Aircraft Consumables & OEM Spare Parts
Quick and safe purchasing for routine maintenance.
Filters, seals, bearings, fasteners, lamps and tires — routine maintenance runs on consumables and OEM spare parts. Aviatrading helps maintenance stores and MROs find them quickly from sellers worldwide, with the condition and certificate type on every listing.
Small parts, big consequences
Consumables are cheap compared with an engine module, but a missing seal or the wrong fastener can hold an aircraft on the ground just as long. And because they are small and plentiful, they are also where untraceable and counterfeit parts most often slip in.
Buying consumables well means two things: getting them fast and getting them with clean traceability. Aviatrading helps with both.
Consumables and expendables
Maintenance teams source:
- Filters — fuel, oil, hydraulic and air filter elements.
- Seals and gaskets — O-rings, packings, gaskets.
- Bearings — ball, roller and spherical bearings.
- Hardware — bolts, nuts, rivets, screws, clamps.
- Lighting — lamps and light assemblies.
- Wheels and tires — tires, tubes and brake wear parts.
- Fluids and lubricants — oils, greases and hydraulic fluids.
Browse seals and gaskets, bearings, metalware and tyres in the catalog.
OEM, PMA and standard parts
Three kinds of parts show up in every stores room:
- OEM parts — made by the original manufacturer of the aircraft, engine or component.
- PMA parts — made by another company under an FAA Parts Manufacturer Approval, often at a lower price. Check that your operator and aviation authority accept them for your aircraft.
- Standard parts — made to a published industry standard such as AN, MS or NAS, like many bolts, nuts and O-rings.
On Aviatrading you can search by the part number you need and compare offers across sellers. For the bigger picture, see aviation aftermarket parts.
Shelf life and traceability
For consumables, check:
- Shelf life — many seals, sealants and adhesives expire a set time after their cure or manufacture date.
- Batch or lot number — so the part can be traced back if a batch is recalled.
- Certificate of conformity — from the manufacturer or distributor, for new standard parts and consumables.
- Packaging — original, sealed packaging and storage conditions.
For OEM rotables and components, ask for a release certificate. Our guide to FAA 8130-3 and EASA Form 1 explains what to look for.
Avoid suspected unapproved parts
Suspected unapproved parts — counterfeit, undocumented or wrongly certified — are a real risk with small, high-volume items. Warning signs include prices far below the market, missing or photocopied paperwork, and packaging that does not match the manufacturer's.
Read our bogus parts policy and non-airworthy parts policy, and always check the traceability documents before you pay.
