Aircraft Maintenance Engineering (AME) is a highly technical and specialized field, and as such, it is divided into several streams or categories depending on the type of aircraft that the AME is qualified to work on. The following are some of the common streams in AME:
Aeroplane Stream: This stream is for AMEs who are qualified to work on fixed-wing aircraft, such as commercial airliners, private jets, and military aircraft.
Helicopter Stream: This stream is for AMEs who are qualified to work on rotary-wing aircraft, such as helicopters.
Avionics Stream: This stream is for AMEs who are qualified to work on the electronic systems of an aircraft, such as navigation, communication, and control systems.
Powerplant Stream: This stream is for AMEs who are qualified to work on the engines of an aircraft, such as turbine and reciprocating engines.
Structures Stream: This stream is for AMEs who are qualified to work on the structural components of an aircraft, such as the fuselage, wings, and tail.
Each stream has its own set of regulations, standards, and type rating exams. It's also worth noting that some institutions or universities may offer a combined AME course that covers all the streams.
