ATA	Description
71 - 7111 Engine Cowl Flaps	Powerplant The flaps mounted in engine cowling for increased cooling air flow. Also includes the component whichelectrically or hydraulically actuates the cowl flaps. Typical parts are actuator, piston, seal, hingebracket, skin, doubler, rod, rod end, lever, rivet, bolt, and flap, etc.
32 - 3213 Main Landing Gear Strut/Axle/Truck	Landing Gear The main landing gear components and parts such as struts, axles, trucks which support the aircraft onthe ground or water. Typical parts are shock device, torque link, beam and skid/shock device onrotorcraft.
71 - 7112 Engine Air Baffle Section	Powerplant For reports of baffles which direct cooling air flow to the engine cylinders and accessories. Does notinclude cylinder baffles certificated with the engine which are filed in JASC code 8530. Typical parts arebaffle, shield, bracket, shroud, cooling ducts for starters, and generators, etc.
32 - 3220 Nose/Tail Landing Gear	Landing Gear The miscellaneous parts of the nose or tail gear system which cannot be directly associated with aspecific nose/tail gear code such as attachment, struts, axles, etc. This code is not to be used forextension/retraction mechanism, steering/dampening system, or doors.
71 - 7120 Engine Mount Section	Powerplant The structural framework which supports the engine on the nacelle, firewall or pylon. Typical parts aremount, bracket, fitting, shock mount, bolt, isolator, hanger, etc.
32 - 3221 Nose/Tail Landing Gear Attach Section	Landing Gear The parts and assemblies that attach the nose/tail gear to the airframe structure. Applicable to fixed orretractable type landing gear.
71 - 7130 Engine Fireseals	Powerplant The fire-resistant partitions and seals mounted on or about the power package to isolate areas subjectto fire. Does not include firewalls which are filed in JASC code 5412. Typical parts are shroud, bracket,etc.
32 - 3222 Nose/Tail Landing Gear Strut/Axle	Landing Gear The nose gear component parts such as shock struts and axles, which support the aircraft on theground. Torque links are included but steering/shimmy dampening systems and units are excluded.
71 - 7160 Engine Air Intake System	Powerplant The portion of the powerplant system which directs airflow to the engine. Does not include integralstructure with the airframe, which shall be included in the applicable structures JASC chapter. Typicalparts are carburetor air heat doors, alternate air doors, linkages, controls, filter element, ducts, hose, airbox, latch, seals, nose ring cowls, scoops, compressor fan cowls, compressor fan case, buried engineducts, vortex generators, actuators, control handles, cables, wiring, plumbing, doors, warning systems,position indicators, etc.
32 - 3230 Landing Gear Retraction/Extension System	Landing Gear The miscellaneous parts of the retraction and extension systems other than actuators, and dooractuating mechanism. Location, such as nose, right or left main should be referenced in the "PartLocation" field unless the defective part is common to all locations. Typical parts are leveling cylinders,centering system, actuator brackets, bungees, emergency extension system parts, uplocks/downlocks,uplock/downlock actuator, drag braces, etc.
