Aviation Machinist's Mate AD
Aviation Machinist's Mates (AD) maintain, inspect, troubleshoot, preserve, and de-preserve aircraft engines and their related systems, including fuel, lubrication, compression, combustion, exhaust, accessory gearbox, aircraft mounted accessory drive, propeller, anti-ice, and bleed air systems.  They conduct special and conditional inspections and oil analysis.  In addition, they conduct functional checks and required adjustments on engines and related systems.  They also supervise and provide training to powerplant work centers.

Aviation Machinist's Mates are aircraft engine mechanics. They inspect, adjust, test, repair and overhaul aircraft engines and propellers. ADs also perform routine maintenance, prepare aircraft for flight and assist in handling aircraft on the ground.

These technicians may also volunteer to fly as Naval aircrew. Aircrew performs numerous in-flight duties and operates aircraft systems in turbojet, helicopter, or propeller aircraft. Aircrew earns additional pay for flying. (See the Aircrew Program for details.)

 

The duties performed by ADs include:

  • maintaining and servicing aircraft engine, fuel and lubrication systems;
  • handling and servicing aircraft ashore or aboard ship;
  • performing complete aircraft turboshaft/turboprop engine repair;
  • determining reasons for engine degradation via spectrometric oil analysis tests;
  • evaluating jet engine performance, using jet test cells for fixed turbojet engines;
  • performing helicopter maintenance, installing and maintaining engines, drive accessories and gear boxes;
  • performing propeller repairs;
  • possibly functioning as aircrewman in various types of aircraft.

 

Working Environment

Aviation Machinist's Mate may be assigned to sea or shore duty any place in the world, so their working environment varies considerably. They may work in hangars or hangar decks, outside on flight decks or flight lines at air stations.


They may work in clean or dirty areas, but they are almost always working in noisy environments.
They work closely with others, do mostly physical work and require little supervision. ADs also serve as flight engineers aboard certain aircraft.

Qualifications

People in this rating should be able to express themselves clearly in speaking and writing. They should have no speech impediment, and they must pass hearing and color perception tests.


ADs need good memories and the ability to do repetitive tasks, perform detailed work and keep accurate records. Manual dexterity and teamwork are also vital. Normal hearing and color perception is required for this rating.

 

AD - Aviation Machinist Mate Intermediate Level
Aviation Machinist’s Mates Intermediate Level conduct intermediate level repair on aircraft engines.  They perform complete intermediate level turboshaft, turbofan, turbojet, and turboprop engine repair to include propellers, rotors, gearboxes, and drive accessories.  In addition, they evaluate turbine engine performance using jet test cells and advanced calibration equipment.

AD - Aviation Machinist Mate Organizational Level
Aviation Machinist’s Mates Organization Level conduct scheduled and unscheduled maintenance on aircraft engines, fuel, and lubrication systems.  They also perform aircraft turboshaft, turbofan, turbojet, and turboprop engine repairs.  Additionally, they perform helicopter and propeller maintenance to include rotors, gearboxes, and drive accessory repairs.  They also evaluate jet engines performance using advanced calibration equipment.

** Note: AM, AME, and AD combine at paygrade E-9 to the rating of Master Chief Aircraft Maintenanceman (AFCM).
