Are Aircraft Cleaning Products “FAA Approved”? What the FAA, EPA, Boeing and Gulfstream Actually Do

Many aircraft detailers and chemical suppliers describe products as “FAA approved.” The phrase sounds reassuring. It suggests that a federal aviation authority tested the cleaner, confirmed that it is safe on every aircraft surface and issued an official approval.

That is not how the system works.

The FAA does not operate a general approval program for aircraft soaps, degreasers, polishes, disinfectants or brightwork coatings. There is no universal FAA stamp that makes a detailing chemical acceptable for every aircraft, every surface and every cleaning task.

What exists instead is a layered system:

  • The aircraft or component manufacturer publishes maintenance procedures and identifies acceptable products, product families or material specifications.
  • Organizations such as Boeing and SAE publish tests that evaluate whether a material is likely to damage aircraft substrates.
  • The EPA regulates products that make disinfecting, sanitizing, insect-control or other pesticidal claims and offers a separate voluntary Safer Choice program for certain cleaners.
  • The operator remains responsible for using the correct current maintenance data for the aircraft, serial number, completion and task.

That distinction matters. A product can be EPA registered but incompatible with an acrylic window. It can pass a Boeing material-compatibility specification but still not be named in the maintenance procedure for a particular Gulfstream. It can be sold through Boeing Distribution without being “FAA approved.” It can also be perfectly appropriate for a limited cabin-cleaning task even though its brand name never appears in an aircraft manual.

The real question is not, “Is this product FAA approved?” It is, “What evidence supports using this product on this surface, for this task, on this aircraft?”

What the FAA actually regulates

The FAA regulates aircraft airworthiness and the performance of maintenance, preventive maintenance, alterations and inspections. It does not ordinarily evaluate bottles of detailing chemicals one by one.

The FAA has addressed aircraft cleaning directly. In InFO 16005, Automotive Detailing Companies Working on Aircraft, the agency explains that the physical act of washing an aircraft, by itself, is usually neither maintenance nor preventive maintenance. However, the complete job frequently includes regulated steps, such as:

  • covering or protecting static ports and other openings;
  • closing and securing panels or fan-cowl doors;
  • completing post-wash inspections;
  • clearing drains;
  • reapplying lubrication or preservatives; and
  • recording maintenance-related work.

Once the work becomes maintenance or preventive maintenance, the applicable rules and technical data matter. Under 14 CFR § 43.13, maintenance personnel generally use the methods, techniques and practices in the current manufacturer’s maintenance manual or Instructions for Continued Airworthiness, or other methods acceptable to the FAA.

There is an important nuance here. The FAA’s Advisory Circular 43-205 explains how alternative chemicals or processes may be qualified. If a task requires FAA-approved maintenance data—an Airworthiness Directive task is a good example—a change to the specified chemical or process may also require FAA approval. For ordinary tasks that do not require approved data, a manufacturer may identify alternatives through manuals, service letters or similar instructions, or compatibility may be supported by suitable testing.

That is very different from the FAA approving a commercial cleaner for general detailing use.

The FAA also publishes useful chemical and process guidance. Its active AC 43-4B, Corrosion Control for Aircraft, says that the aircraft manufacturer’s corrosion program takes precedence when one exists. Among its practical recommendations:

  • Cleaning compounds with a pH greater than 10 are not recommended for metal cleaning.
  • More concentrate is not automatically better; excessive concentration can raise pH and cause damage.
  • A thixotropic cleaner meeting the applicable specification can be used in wheel wells where water rinsing is permitted.
  • Solvents differ greatly in toxicity, flammability and their effect on paint, so they are best limited to the correct local application.
  • Steam cleaning is not recommended for general aircraft use because it can erode paint, craze plastics, debond adhesives, damage electrical insulation and remove lubrication from bearings.
  • After washing, rinse away the cleaner, inspect drains and water traps, lubricate as required and reapply preservation.

So the FAA regulates the airworthiness context and provides accepted practices. It does not award a universal “FAA approved cleaner” badge.

What EPA registration means—and what it does not mean

The EPA is responsible for a different question.

An ordinary cleaning product that only claims to remove dirt, stains, grease or odors is generally not a pesticide. EPA explains that when a product claims to sanitize, disinfect, sterilize, kill germs or otherwise mitigate a pest, it becomes subject to the registration provisions of the Federal Insecticide, Fungicide, and Rodenticide Act unless an exemption applies. The distinction is explained in the EPA’s guidance on determining whether a cleaning product is a pesticide.

For a disinfectant, “EPA registered” is the accurate term. EPA reviews the data supporting the pesticidal claims and accepts the product’s registration and label, including where and how it may be used, what organisms it controls and the required contact time. The label is a legal use document.

EPA registration does not by itself establish that a product:

  • will not craze an aircraft transparency;
  • is harmless to every paint, sealant, plated finish, leather or fire-treated fabric;
  • may be fogged around avionics, smoke detectors or electrical equipment;
  • is authorized by the aircraft OEM; or
  • is suitable for every cabin surface merely because “aircraft” appears somewhere on the label.

Material compatibility and disinfectant efficacy are separate questions. A good aviation disinfectant should satisfy both.

Examples of products EPA has reviewed

AeroDis 7127 is a useful example. Its EPA-accepted label carries Registration No. 84683-3-67026, identifies aircraft lavatories, galleys, windows and transparencies, tray tables, overhead bins and other hard aircraft surfaces, and states that the product meets AMS 1452 and AMS 1453. Yet the Boeing Distribution listing for AeroDis 7127 shows its FAA Approval Code as “N/R”—not required or not reported. That is a concrete illustration of the difference between EPA registration, aviation material testing, a distributor listing and FAA approval.

Calla 1452 is another aviation-focused disinfectant. It is EPA registered and is marketed for hard, nonporous surfaces with a specified dilution and wet contact time. That EPA registration supports the disinfecting claim; the product’s aviation specifications and the applicable aircraft manual address compatibility and use.

EPA’s pesticide database also contains mainstream products whose approved use sites include aircraft. For example, the EPA record for a PURELL multi-surface disinfectant registration lists “aircraft” among its use sites. That does not make the product universally compatible with every aircraft material. It means the EPA-accepted label permits the pesticidal use described on that label.

EPA also runs the voluntary Safer Choice program. Its current Safer Choice product list includes a small aircraft-cleaning category with examples such as Calla 301A Degreaser Concentrate, X-405 Window Cleaner Concentrate and X-410Q Interior Cleaner Concentrate. This is not a mandatory review of all aircraft cleaners, and it is not an FAA or OEM approval. It is a separate EPA certification against the Safer Choice standard.

The overlap can look contradictory until the scope is understood. Calla 301A appears in EPA’s aircraft-cleaning category, while its Boeing Distribution listing reports a concentrate pH of 12 to 12.5. FAA corrosion guidance says cleaners above pH 10 are not recommended for metal cleaning. Safer Choice certification does not cancel that aircraft-material precaution; the intended surface, required dilution and final use concentration still matter. Different programs are answering different questions.

This is why saying “EPA approved” can also be imprecise. Better language is:

  • “EPA registered under Reg. No. ______ for the labeled disinfecting use”; or
  • “EPA Safer Choice certified.”

Callington’s aircraft insecticides provide an especially clear example of what EPA review actually means. When EPA reviewed Callington 1-Shot Aircraft Insecticide, EPA required the labeling to limit the product to aircraft cargo holds. The EPA-accepted amended label from 2012, under EPA Registration No. 83795-1, describes it as an insecticide for “cargo holds only.” A later accepted version expressly states, “Do not use in aircraft cabins,” requires application while the aircraft is unoccupied and on the ground, and requires fresh-air ventilation for 30 minutes before passengers board.

By contrast, EPA conditionally registered Callington Pre-Spray Aircraft Insecticide on May 15, 2025, under EPA Registration No. 92953-1. Its label permits pre-embarkation treatment of unoccupied aircraft cabin, crew and cargo areas—but prohibits application to an occupied aircraft. Applications must be performed by properly trained airline personnel. The product must dry for at least 10 minutes, followed by at least 10 minutes of ventilation, before passengers and crew may board.

This comparison shows that EPA does review certain aircraft products when they are legally pesticides, and that its review can determine precisely where, when and how a product may be applied. One-Shot is limited to cargo holds; Pre-Spray may be used in unoccupied cabin areas under its specific directions. But EPA registration is not an FAA approval, an OEM endorsement or confirmation that the product is compatible with every aircraft material. In fact, EPA’s own registration notice states that registration must not be construed as an endorsement or recommendation of the product.

What Boeing really does

Boeing’s system is often the source of the “certified” or “approved” language used in chemical marketing. To understand it, separate four different things:

  1. The model- and task-specific Aircraft Maintenance Manual (AMM). This is the first place to look for the actual cleaning procedure, required precautions and consumable references.
  2. A material-evaluation specification. Boeing D6-17487 and the newer BSS 7432 provide test requirements for categories of maintenance materials. Passing a specification shows conformance to defined tests.
  3. A Boeing test letter or No Technical Objection (NTO). This documents the scope of Boeing’s review. It is not automatically the same as regulatory approval or a blanket authorization for every application.
  4. A Boeing Distribution catalog listing. Boeing sells thousands of cleaners and consumables. Catalog availability is not proof that the product is specified for every Boeing aircraft or task.

What D6-17487 testing actually evaluates

For general exterior cleaners, waxes, polishes and polishing compounds, commonly cited D6-17487 testing includes:

  • sandwich corrosion;
  • acrylic crazing;
  • paint softening; and
  • hydrogen embrittlement.

Those are serious aviation-compatibility tests. They address risks that an ordinary automotive or household product manufacturer may never have evaluated.

But passing them is not the same as receiving a unique FAA certificate number. D6-17487 is the document/specification number. A supplier may have a report number, a test-laboratory certificate or a Boeing letter, but Boeing is not handing the product an “FAA approval number.”

The clearest example is Boeing’s 2004 evaluation of Nuvite NuPower II. Boeing tested it to D6-17487 Revision P and reported that it passed sandwich-corrosion, acrylic-crazing, paint-softening and hydrogen-embrittlement tests. Boeing then stated that it had “no technical objection” to maintenance-facility use. In the same letter, Boeing made no claim or guarantee about the cleaner’s actual polishing performance.

That is more precise—and more useful—than calling NuPower II “FAA approved.”

Examples of Boeing-Specification Products

The following examples show how to read the available evidence without overstating what it means.

NuPower II

What the documentation supports: Boeing tested NuPower II to D6-17487 Revision P. It passed sandwich-corrosion, acrylic-crazing, paint-softening and hydrogen-embrittlement tests. Boeing issued a No Technical Objection for maintenance-facility use.

What it does not prove: This is not a performance guarantee, FAA approval or permission to use the product on every aircraft surface.

Calla 500

What the documentation supports: Boeing Distribution says Calla 500 conforms to D6-17487, AMS 1526 and other specifications. It is intended for exhaust deposits and general exterior cleaning.

What it does not prove: This does not establish blanket acceptance for every Boeing model, dilution or cleaning task. Its Boeing catalog page lists the FAA Approval Code as “N/R.”

LPS Precision Cleaner/Degreaser

What the documentation supports: The product is listed as conforming to Boeing D6-17487 Revision T and SAE AMS 1526C for exterior-cleaning compatibility.

What it does not prove: This does not authorize users to disregard the current AMM or apply the product around every sensor, transparency or aircraft component.

AeroDis 7127

What the documentation supports: AeroDis 7127 is an EPA-registered aircraft disinfectant with AMS 1452 and AMS 1453 claims and aircraft-specific use directions.

What it does not prove: EPA registration and aviation compatibility testing do not constitute universal FAA or Boeing approval for every cabin material.

Boeing’s cleaning process is as important as the bottle

Boeing’s published aircraft-cleaning process emphasizes a controlled sequence:

  1. Inspect the aircraft and identify heavy contamination or damage.
  2. Close doors, windows and hatches, and protect sensors, antennas, pitot probes and openings as required.
  3. Remove loose contamination with a pre-rinse.
  4. Mix the aircraft cleaner at the specified dilution and use soft, nonabrasive tools.
  5. Use low-pressure washing and avoid high pressure near rivets and seams.
  6. Thoroughly rinse before cleaner residue dries.
  7. Spot-clean fuel, hydraulic fluid, carbon or tar only with a suitable specialty cleaner.
  8. Dry and inspect the aircraft.
  9. Remove protection, check drains and perform the required follow-on work.
  10. Lubricate or preserve components when the maintenance procedure requires it.

Publicly indexed 737 AMM material reinforces the same point: cleaning is tied to inspection for leaks, corrosion, staining and deterioration, and the procedure cross-references separate tasks for polishing and corrosion removal. The AMM uses consumable codes and specifications, not a simple universal “approved products” shelf.

For a Boeing aircraft, the correct question is therefore: “What does the current AMM task for this airplane and area require, and does this product have traceable conformity to the required specification at the intended concentration?”

Gulfstream: the OEM that often gives the strongest product-level guidance

Gulfstream documentation is a good example of why aircraft detailing cannot be reduced to a single approved-products list.

An older G550 Completion Center Maintenance Handbook gives material-specific instructions for wood, granite, Lexan, vinyl laminate, plated finishes, stainless steel, leather, carpet and fabric. It names products that would surprise anyone expecting every acceptable cleaner to have an aviation-only label:

  • Brillianize or Plexiglas cleaner for Lexan;
  • Pledge only to minimize scratches in Lexan;
  • Meguiar’s No. 34 or New Life Cream Polish for certain vinyl-laminate work;
  • mild commercial liquid soap for leather or rubber; and
  • warm soapy water for stainless steel.

The same handbook also contains strong limitations. It says not to clean Lexan in a circular motion, not to bring regular chlorine bleach such as Clorox aboard the aircraft, not to use full-strength bleach on carpet or fabric, and not to use unlisted materials on treated fabric. It warns that aggressive cleaning can remove fire retardant and compromise flammability characteristics.

A G550 external-washing AMM task dated June 30, 2011 is even more explicit. It says pressure washing is not recommended, water pressure should be minimized, cleaning agent should be pH-neutral or slightly alkaline, and Formula 409 “is not authorized for use on Gulfstream aircraft” because of corrosive properties. It also calls for landing-gear lubrication before washing and cautions against chloride-containing fluids around engine and APU intakes.

Gulfstream’s exterior procedures can be equally specific. A publicly available G550 wing-leading-edge procedure states:

  • no sanding;
  • no chlorinated solvents or chlorinated cleaners;
  • clean with a lint-free cloth and an approved solvent; and
  • do not remove the protective Alclad layer during polishing.

These are exactly the kinds of surface-specific restrictions a generic “aircraft safe” label cannot replace.

The Gulfstream brightwork change: from Xzilon 3 to Skyde Clear

The history is revealing.

In the G650 exterior-metallic-surfaces polishing program revised November 30, 2017, Gulfstream recommended Xzilon 3 as additional corrosion protection in corrosion-prone environments. The same document required Xzilon 3 on the cockpit windshield and side-window frames regardless of operating environment. The program also warned that Xzilon dulled the shiny finish.

Public documentation shows a different direction emerging in 2023.

Skyde Clear, made by Nuvite, was introduced publicly in fall 2023. Its technical data sheet identifies Gulfstream GAMPS 4001 and Boeing BSS 7432, and describes a one-coat polymeric clear coating for polished bare aluminum. The documented application covers leading edges, winglets, stabilizers and inlets.

Frasers Aerospace, Nuvite’s distributor and training partner, reports that Gulfstream engineers assisted with the product’s development and that the first practical training at Gulfstream Farnborough was followed by a planned rollout to other Gulfstream service centers. Its explanation for the change is straightforward: existing approved products were providing little practical protection, while Gulfstream testing of Skyde Clear reportedly produced approximately six months of protection with normal cleaning and no repolishing.

The operational advantages are easy to understand:

  • longer intervals between polishing;
  • less labor and downtime;
  • less repeated metal removal over the life of the aircraft;
  • improved corrosion protection in coastal or otherwise corrosive environments; and
  • one coating application rather than multiple coats.

Skyde Clear also has tradeoffs. It is a coating, so the final appearance depends heavily on preparation and application technique, and some dulling may occur. The surface must be free of polish and contamination. Application lines should be controlled and overlapping after the coating becomes tacky must be avoided. Cured coating removal requires compounding or the approved stripping process.

Did Gulfstream completely replace Xzilon or make Skyde Clear mandatory?

The public evidence supports this much:

  • Xzilon 3 was explicitly recommended—and required in limited G650 frame locations—in the 2017 program.
  • Skyde Clear was publicly described as approved for Gulfstream leading edges by October 2023.
  • Skyde Clear documentation identifies Gulfstream GAMPS 4001.
  • Gulfstream engineers reportedly supported development and the product began rolling into Gulfstream service centers.

What the public evidence does not conclusively establish is that Gulfstream formally withdrew Xzilon from every current model document or made Skyde Clear mandatory fleetwide. Current Gulfstream manuals and technical bulletins are generally available to customers through MyGulfstream, not as a complete public library.

The accurate conclusion is that Gulfstream moved from a documented Xzilon-centered approach toward approving and deploying Skyde Clear as a longer-lasting alternative. Before treating that as a mandatory replacement on a particular aircraft or location, the operator should verify the latest model-specific AMM, GAMPS 4001, service information and Aircraft Maintenance Program.

Other OEM examples prove that “aviation product” is not a simple category

Cessna manuals have historically permitted ordinary mild soap or dishwashing liquid for certain cleaning tasks while prohibiting household glass spray and specific solvents around aircraft transparencies. Some Cessna data also warns against silicone-based exterior wax because of static buildup and warns that high-pressure washing can remove grease and damage sensitive components.

Salts Gone reported in August 2024 that its Aviation Formula had been added to Cessna maintenance documentation after testing to AMS 1526C. The manufacturer also publishes claimed Cessna manual excerpts and its AMS test documentation. That is meaningful when the current manual for the applicable model and task contains the reference. Until confirmed in current Textron-controlled data, the vendor’s broad statement that it appears in “all” Cessna manuals should not be stretched into acceptance for every Textron aircraft, component or cleaning task.

Airbus provides another useful contrast. Airbus uses its AMM and Consumable Materials List and evaluates maintenance materials to AIMS 09-00-002. In a published dry-wash information document, Airbus said conformity to AIMS 09-00-002 helps demonstrate that a compound will not degrade painted exterior surfaces when properly used—but Airbus still did not recommend dry or waterless cleaning because of concerns about residue, long-term coating effects and micro-scratching. Airbus described it as an operator-responsibility practice only when the AMM exterior-cleaning task is followed. Passing a material test did not automatically make the entire process recommended.

Airbus consumable references can also be product-specific. A supplier’s aerospace-approvals summary for Samsol T1, for example, identifies an Airbus CML reference and A330 AMM Item 11-002 for dry-cleaning solvent. That is useful traceability, but the supplier sheet is not a substitute for confirming the current CML and AMM applicability.

Bombardier provides an unusually narrow example of language that really does become mandatory. Transport Canada AD CF-2025-57, addressing missing clad material on certain Global-series vertical-stabilizer leading edges, requires inspection and—when applicable—corrosion removal, eddy-current testing and application of Xzilon 3, or an approved Bombardier disposition. That is not a general endorsement of Xzilon for all Bombardier detailing. It is a required action for a defined unsafe condition, aircraft group, location and procedure. The scope is what gives the word “required” its meaning.

That is a recurring lesson: product compatibility, procedure acceptance and task authorization are related, but they are not identical.

Why is all of this so confusing?

Because the aviation industry uses the word “approved” for several very different things:

  • FAA approved data: regulatory approval in a maintenance or certification context.
  • EPA registered: a pesticide or disinfectant label reviewed under FIFRA.
  • EPA Safer Choice certified: voluntary certification to a safer-chemistry standard.
  • OEM listed or recommended: a manufacturer names a product or product type in a manual, service document or material specification.
  • Meets Boeing D6-17487/BSS 7432 or an SAE AMS: the product has evidence of conformity to defined tests.
  • No Technical Objection: an OEM reviewed a specific proposal or material within a defined scope and identified no technical objection.
  • Sold by Boeing Distribution: the product is available through a Boeing-owned supply channel.
  • Operator approved: an airline or flight department has accepted the product into its own controlled procedure.

Those phrases are not interchangeable.

The confusion gets worse because many current OEM manuals are behind customer portals, procedures vary by serial number and interior completion, and vendors naturally compress a long technical story into a short marketing phrase. “FAA approved” fits on a label. “Tested to Boeing D6-17487 Revision T for exterior-cleaner compatibility at the specified dilution, subject to the current model-specific AMM” does not.

But the longer sentence is much closer to the truth.

Then what products should an aircraft detailer use?

Use a decision hierarchy instead of searching for one universal approval.

1. Identify the exact surface and task

“Cleaning an airplane” is not one task. Painted exterior, bare aluminum brightwork, acrylic windows, composite structures, landing gear, wheel wells, leather, veneer, stone, plated fixtures, fabric, carpet, lavatory surfaces and touchscreens all have different risks.

2. Start with the current aircraft-specific instructions

Check the current AMM, Completion Center Maintenance Handbook, Component Maintenance Manual, operator procedure and any coating or interior warranty instructions that apply to the exact aircraft and configuration.

If the OEM names a product, prioritize it. If the OEM names a material specification or consumable code, select a product with traceable evidence that it conforms to the current required specification.

3. For disinfecting, check both regulatory status and aircraft compatibility

Prioritize an EPA-registered product whose label covers the intended site, surface and organism. Confirm its dilution, application method and wet contact time. Then verify that the product also meets the relevant aviation compatibility standard—such as AMS 1452/1453—or is accepted in the applicable OEM/operator procedure.

EPA registration without material compatibility is incomplete. Material compatibility without EPA registration is also incomplete when the product makes a disinfecting claim.

4. Respect material and process limits

Do not use a product merely because the manual fails to name it as prohibited. Look for restrictions on:

  • pH;
  • chlorine, ammonia, ketones or chlorinated solvents;
  • abrasives;
  • silicone;
  • flammability;
  • pressure and temperature;
  • dwell time;
  • rinsing and residue;
  • application around electrical equipment, sensors and transparencies; and
  • required lubrication or preservation after cleaning.

5. When the manual is silent, build evidence

The absence of a brand name does not automatically make a product unacceptable. A sensible substitution file can include:

  • the product’s SDS and technical data sheet;
  • the exact intended dilution and application process;
  • independent test reports to relevant Boeing, Airbus, SAE or military specifications;
  • written OEM or engineering concurrence when available;
  • operator authorization; and
  • a controlled test on an inconspicuous area for cosmetic compatibility.

An inconspicuous test can reveal staining or gloss change. It cannot prove the absence of sandwich corrosion, hydrogen embrittlement, acrylic stress crazing or long-term damage. That is why laboratory evidence still matters.

6. Document what was used

For professional work, record the product, dilution, lot when appropriate, surface, dwell time, procedure/manual reference and any required follow-on inspection, lubrication or preservation. Good traceability is more defensible than a vague “aircraft approved” claim.

A practical example: can we use Lysol in the lavatory?

Often, yes—but the reasoning should be better than “no one says we cannot.”

If the task is simple cleaning of a compatible toilet or hard, nonporous lavatory surface, a suitable household-type cleaner may be acceptable when the current aircraft or completion manual does not prohibit it and the operator accepts it. Gulfstream’s own older completion handbook is proof that OEMs sometimes name ordinary commercial products rather than aviation-exclusive chemicals.

If the task is disinfection, use a specific EPA-registered Lysol product according to its label. Verify that the label covers the surface and use site, and follow the required contact time. Do not assume that one Lysol formula is interchangeable with another.

Then consider the aircraft:

  • Avoid overspray on plated fixtures, acrylic, leather, fabric, wood veneer, touchscreens, electrical equipment and smoke detectors.
  • Apply product to the cloth rather than spraying around sensitive equipment when the OEM procedure calls for controlled application.
  • Do not mix it with bleach, ammonia or another cleaner.
  • Rinse or wipe residues when required by the label or aircraft instructions.
  • If the operator wants the strongest aviation traceability, prioritize an EPA-registered aircraft disinfectant that also carries aviation compatibility testing, such as AeroDis 7127 or Calla 1452.

The practical answer is not that Lysol is “FAA approved.” It is that a particular EPA-registered formulation may be appropriate for a particular lavatory surface when used according to its label, the aircraft documentation and the operator’s procedure.

Better language for detailers and product suppliers

Instead of writing:

We use only FAA-approved aircraft products.

Use specific, verifiable language:

We select products according to the aircraft manufacturer’s current maintenance instructions and operator requirements. Where applicable, we use products with documented conformity to Boeing, Airbus or SAE material-compatibility specifications and EPA-registered disinfectants according to their labels.

For an individual product, say exactly what the evidence shows:

  • “Tested to Boeing D6-17487 Revision P.”
  • “Conforms to SAE AMS 1526C.”
  • “Named in Gulfstream GAMPS 4001.”
  • “Boeing issued a No Technical Objection dated April 28, 2004.”
  • “EPA Reg. No. 84683-3-67026; aircraft hard-surface uses appear on the label.”
  • “Listed in AMM task ______ for this aircraft model and revision.”

Specific language builds more trust than an approval claim that cannot be produced.

The bottom line

There is no single government agency that universally approves or rejects every chemical used to detail aircraft.

The FAA regulates airworthiness, maintenance performance and the use of approved or acceptable technical data. The EPA regulates pesticidal claims and offers voluntary safer-chemistry certification. OEMs publish task-specific procedures, product recommendations and material specifications. Test laboratories establish whether a chemical conforms to defined compatibility tests. Operators control the procedures used on their fleets.

When a current OEM procedure recommends a product, prioritize it. When the OEM specifies a material standard, use a product with traceable conformity to that standard. When disinfecting, prioritize an EPA-registered product whose label includes the intended use and whose aircraft-material compatibility is also supported. When the manual warns against a pH range, solvent family, abrasive, pressure or application method, respect that limit.

And when a supplier says “FAA approved,” ask the most useful follow-up question in aircraft detailing:

Approved by whom, under what document, for which aircraft, surface, task, concentration and revision?
