History
Between 1948 and 2001, the AM rating consisted of two additional service ratings:
- AM - Aviation Structural Mechanic
- AME - Aviation Structural Mechanic (Equipment)
- AMH - Aviation Structural Mechanic (Hydraulics)
- AMS - Aviation Structural Mechanic (Structures)
AME's maintain and repair oxygen, cockpit and cabin pressurization, and ejection seat systems. The AMH was for hydraulic systems (landing gear, brakes, flight controls and all related). The AMS was structural/sheet metal. Today's AM rating began from the Aviation Metalsmith used between 1921 and 1948.
