context_page_description: Aviation structural mechanic is a United States Navy occupational rating.
context_section_description: Aviation structural mechanics maintain aircraft airframe and structural components including flight surfaces and controls, hydraulic and pneumatic control and actuating systems and mechanisms, landing gear systems, air conditioning, pressurization, visual improvement, oxygen and other utility systems, egress systems including seat and canopy ejection systems and components.  They fabricate and repair metallic and nonmetallic materials; perform aircraft daily, special, hourly, and conditional inspections, supervise operation of airframe work centers; maintain aircraft metallic and non-metallic structures including fuselages, fixed and moveable flight surfaces, tail booms, doors, panels, decks, empennages, and seats (except ejection seats); flight controls and related mechanisms; hydraulic power storage and distribution systems including main (primary and secondary), auxiliary (utility), and emergency systems; hydraulic actuating subsystems; landing gear systems including wheels and tires, brakes, and emergency systems; pneumatic power, storage and distribution systems; hoists and winches, wing and tail fold systems; launch and arresting gear systems; hydraulic component repair and test.
  Aviation structural mechanics, safety equipment (AME) maintain safety belts, shoulder harnesses and integrated flight harnesses in aircraft, inertia reels, seat and canopy ejection systems, gaseous and liquid oxygen systems, life raft ejection systems, fire extinguishing systems excluding fire detection systems, portable fire extinguishers, emergency egress systems, air-conditioning, heating cabin and cockpit pressurization, ventilating and antiGsystems, visual improvement systems, other utility systems and associated lines, fittings, rigging, valves and control mechanisms; replenish liquid and gaseous oxygen systems; remove and install oxygen system valves, gages, converters and regulators; inspect, remove, install and rig ejection seats, shoulder harnesses, lap belts and face curtain mechanisms; inspect, remove, install and adjust firing mechanisms and cartridges for ejection seats, lap belts and canopies; operate and maintain liquid nitrogen and liquid and gaseous oxygen shop transfer and recharge equipment; perform daily, preflight, postflight and other periodic aircraft inspections.
  Since 2001, the occupational rating has been divided into two service ratings for E3-E7: 
  AM - aviation structural mechanic
  AME - aviation structural mechanic (safety equipment)
  At the E-8 level, AM and AME personnel may be advanced to AMCS (senior chief aviation structural mechanic). At the E-9 level, AMCS and ADCS (senior chief aviation machinist's mate) personnel look towards advancement to AFCM (master chief aviation maintenanceman).
