Rapid Response MRO: Building the Ultimate AOG Consumables Kit
When it comes to rapid action and maintenance response, the best approach is a well-stocked kit with common lubricants, sealants, and oils widely used across aircraft in the field. These should be consumables that work across most aircraft you encounter, not specialty materials.
When you need to build or replenish your AOG kit, talk to us at Greenwood Aerospace. We carry hundreds of the most common consumable items listed on GSA Advantage for your convenience and ease of procurement. Make sure to check out our products there, and you can also go straight to the links in our quick buy table below.
What AOG Kits Are For
AOG kits are built for teams that are on the road, responding to maintenance actions at the local station or on the road. AOGs mostly operate out of vans or trucks, so they need everything for the mission at hand packaged in a neat and organized kit.
Since they are responding to maintenance calls that might be hours from home, your AOG teams need all the materials for every repair on hand without having to restock. See, it is the responsibility of AOG teams to go to stricken or grounded aircraft, diagnose the problem, and repair it on site.
Since these repairs that AOGs are called on are often a distance from a home base, the kit needs to be lean enough to fit in a van or truck, yet well-curated enough to include the core adhesives, tapes, abrasives, and greases needed daily.
Let’s dive into the core products for each section of the kit.
Structural Epoxies for Field Repairs
Let’s start with common structural epoxies. Epoxies have virtually limitless value in your toolkit because they are used for so many different applications. They are a truly multi-use adhesive used all over the aircraft for all kinds of things. They are generally sandable and paintable, can fill voids, and are used for a ton of other jobs.
These are the core epoxies we suggest you stock in your road kits to bond common substrates throughout the aircraft.
Contact & Gasket Adhesives
Moving on to contact and gasket adhesives, 3M EC-1300L and Dapco 3300 silicone adhesive kits are among our go-to adhesives in this space.
3M EC-1300L is a standard staple product used for bonding, creating seals, and many other common applications. It is a yellow, solvent-based contact adhesive that provides an excellent initial high-tack, uniform bond strength, and reliable flexibility.
Dapco 3300 silicone adhesive kits are available in 4 oz and pint sizes and are designed for high-temperature and firewall-adjacent bonding applications. This particular RTV sealant maintains elasticity and adhesion under sustained heat exposure, making it well-suited for gap filling in engine bays and other thermally stressed areas of the aircraft where other sealants fail.
Windshield Sealants and Other Specialty Adhesives
Now, let’s talk about windshield sealants and other specialty sealants.
The windshield takes a beating and must remain fully sealed. Pounding rain, jet streams, you name it. The sealants must be built for the rigors of being at the very leading edge of the aircraft and sealing the windshield fully.
Top 5 Tapes Every AOG Team Carries
Moving on to the tapes that every AOG team needs in their kit.
Surface Protection & Erosion Tapes
3M is the Big Kahuna of aircraft-grade tapes, and Greenwood Aerospace has them.
Polyurethane protective tapes are an indispensable tool for leading-edge protection on wings, stabilizers, and radomes.
Glass cloth tapes are well known in the composite aircraft community, as they are widely used in those aircraft designs. But they are also used in standard aircraft compositions.
We sell the polyurethane tapes in several different widths and types
- 3M 8671, 8681HS, and 8663DI polyurethane protective tapes (2–12 in widths) for leading edges, struts, and radomes.
- 3M 5451/5453 PTFE and glass‑cloth tapes as anti‑chafe and high‑temp protection options.
Marking, Masking, and Cabin Tapes
Moving on to marking, masking, and cabin tapes.
These tapes are widely used for a variety of tasks throughout the aircraft. Marking and masking tapes are used for the painting process to mark the lines for different shades and contrasts, and so on.
For carpet work, you might also want to stock Orcon 21000 tape, and for Cessna-specific applications, Cessna S1078-2 fabric tape is a great option for OEM repairs.
OEM and Utility Tapes
You will need general-use tape for many tasks, so make sure you have plenty.
If you work on ANY type of propeller-driven aircraft, you will want to stock up on tapes specific to the task at hand.
Hartzell B‑6654‑100 pressure‑sensitive tape, 1 in × 36 yd, for propeller and spinner quick fixes, is a must-have for all of you King Air AOGs out there.
Jaco Aerospace P55‑2IN white tape, 2 in × 25 yd, is a multi‑purpose utility tape that can be used on carpet since it is flame-retardant tape for seams. Again, if you work on aircraft with carpet and other interior furnishing, you will want these.
Abrasives & Surface Prep That Actually Fit in a Kit
Surface prep is an integral part of all corrosion repair, and the odds are extraordinarily high that you will need it throughout the process.
Hand Abrasives and Pads
When you're working in tight spaces or on delicate surfaces where power tools would be overkill, hand abrasives are your best friend. The 3M Scotch-Brite 7447 general-purpose hand pads (6 in × 9 in, 20 per box, 5 per pack) are the workhorse of surface prep in AOG kits. These maroon pads are perfect for removing corrosion, scuffing paint before bonding, and general surface prep.
They're aggressive enough to remove light corrosion and oxidation, but won't gouge aluminum or composite substrates when used properly.
Cleaners, Degreasers, and Primers
Let’s talk cleaning products that make prep work stick.
Clean surfaces are non-negotiable, and your AOG loadout must use a layered approach to surface preparation.
Eastman Skykleen 1000 solvent is your surface cleaner before any bonding or sealing operation. Available in aerosol 16 oz cans for spot work and 5-gallon pails for depot-level consumption, Skykleen 1000 is approved under many OEM specs and removes oils, greases, and light contaminants without leaving residue.
The aerosol is perfect for AOG work—just spray, wipe with a clean lint-free cloth, and you’re ready to bond. It evaporates quickly and doesn’t require a secondary rinse, which is critical when working in the field without a wash rack.
After your surface is prepped and sealed, you need to protect those joints. Henkel/Hysol and PPG CA1000/CA1010 Mastinox jointing compounds come in small cartridges for joint protection after prep.
These anti-corrosion compounds create a protective barrier over fasteners, lap joints, and other vulnerable areas where moisture intrusion could restart the corrosion cycle. The cartridge format means you can apply them precisely without waste, and they cure to a flexible protective film that moves with the airframe.
Grease & Lube Load-Outs for Mixed Fleets
Now, we need to move on to greases and lubricants. These are absolutely critical infrastructure items used daily; if adhesives are the backbone, then greases and lubricants are the circulatory system. Every single moving part of the aircraft, from the landing gear, struts, and flight control linkages, depends on proper lubrication to operate smoothly.
If you think this is an inflated overview, realize that aircraft have had to return to base after takeoff when the gear failed to retract. After a ground retraction, the diagnosis was inadequate lubrication of the landing gear.
Core Airframe Greases
These greases should be in all AOG kits. These products are daily go-tos that lubricate bearings, landing gear, and most lube points across the entire airframe.
Here’s the quick breakdown of what each Aeroshell grease does best:
- Aeroshell 22 is your general-purpose, extreme-pressure grease for wheel bearings, actuators, and heavily loaded applications. It’s rated from -65°F to +450°F and approved for everything from Cessnas to wide-bodies.
- Aeroshell 33 is a medium load grease for flight control bearings, hinges, and general airframe use. It’s the “if you can only carry one grease” choice for light to medium aircraft.
- Aeroshell 5 and 6 are general-purpose greases with good low-temperature performance, often specified for control surface bearings and general mechanisms.
- Aeroshell 7 is a low-temperature grease for arctic and high-altitude operations where other greases stiffen. If you support operations in cold climates, this is non-negotiable.
- Aeroshell 14 is an extreme-pressure, high-load grease for landing gear, flap tracks, and other heavily loaded sliding surfaces.
- Aeroshell 64 is a wide-temperature-range synthetic grease approved for wheel bearings and systems that experience both extreme heat and extreme cold.
ExxonMobil Mobil Grease 28 and 33 complete your core grease offering. These are widely approved in mixed OEM environments and cross-reference to Aeroshell products in maintenance manuals. Mobil Grease 28 is an extreme-pressure synthetic grease similar to Aeroshell 22 and 64: use it on wheel bearings, actuators, and heavily loaded components.
Mobil Grease 33 is a general-purpose airframe grease that competes with Aeroshell 33 and is approved on a wide range of aircraft. We stock both cartridges for easy grease gun dispensing and small pails for shop or depot use.
The reason to carry both Aeroshell and Mobil Grease is flexibility. Some maintenance manuals specify one brand, some specify the other, and some allow either. By carrying both, you eliminate guesswork and ensure compliance regardless of which aircraft you’re working on.
Specialty and High-Performance Lubes
Moving on, let’s look at a handful of specialty lubricants. These are ones you might not use daily, but are common enough to keep on hand and in your kit for that rainy day.
LANXESS/Royco greases and oils, specifically 11MS, 22CF, 27, 43, 481, 500, and 555, are your MIL-spec workhorses. If you're working on military aircraft or aging civilian aircraft with military heritage (think DC-3s, King Airs, and older bizjets), these products are specified by number in the maintenance manuals. Royco 11MS is a rust-inhibited mineral oil for instruments and hydraulic systems.
Royco 22CF is a corrosion-preventive compound for long-term storage and preservation. Royco 27 is a general-purpose mineral oil for actuators and mechanisms. The 43, 481, 500, and 555 variants cover everything from synthetic hydraulic fluids to preservative oils for specific military applications. These aren't products you use speculatively—you carry them because the manual calls them out by MIL-PRF number, and nothing else is acceptable.

Penetrants and Corrosion Preventives
Corrosion preventatives are another core lubricant product you need to stock in your AOG kit.
When you're working on aircraft in the field, you will encounter seized fasteners, corrosion, and hardware that needs protection where traditional greases fail. These products are your first line of defense against corrosion in the field and your last resort for removing stuck components without resorting to destructive methods.
Kano Aerokroil 10 oz aerosols for freeing seized fasteners without collateral damage.
Unlike penetrating oils, which rely completely on viscosity. AeroKroil uses capillary action to work itself into the tightest spaces between threads and bearing surfaces. It breaks down rust and other corrosion, removes carbon deposits, and displaces moisture, making it a more useful product than competitors like WD-40. It also does this without attacking paints, melting plastics, or damaging composite materials.
For active corrosion arrest and long-term cavity treatment, you need CorrosionX aerosol (U074092) and Lear Chemical ACF-50. These are beyond just penetrants; they are corrosion inhibitors that actively prevent oxidation and provide long-lasting protection in areas that are not easy to re-treat.
CorrosionX is a polar bonding fluid that bonds to metal surfaces and also displaces moisture at a microscopic level. Spray it into wing spars, onto control cables, landing gear cavities, and anywhere else where moisture or intrusion is a problem, and it creates a self-healing protective film that will last for months on end. Lear Chemical ACF-50 takes a different approach. It is specifically designed for aviation use and excels at treating hard-to-reach internal structures and preventing filiform corrosion beneath the paint. You will need this product to treat the interiors of control surfaces, seal lap joints, and protect cable systems. Some operators even fogged the entire airframe with ACF-50 as part of a corrosion preventive program.
Finally, we have Sandstrom 28A dry‑film lubricant aerosols (DFL‑E628) for hardware where grease is not acceptable. This dry film lubricant deposits a thin layer of solid lubricant, typically molybdenum disulfide or PTFE, and provides lubrication without mess, contamination risk, or dirt attraction.
See, greases and wet oils are also major attractants for dirt, which can cause corrosion on your components. There are certain areas where dry film lubricants are the only option to prevent caking from dirt and grime.
