The Aircraft Gas Turbine Engine Repair and Overhaul Technician’s primary responsibilities include:

  • repair and overhaul of gas turbine engines
  • rebuilding gas turbine engines
  • balancing components and assemblies
  • testing and troubleshooting gas turbine engines, and
  • inspecting gas turbine engine components and assemblies

In some companies, the job of the gas turbine engine repair and overhaul technician is broken down into three roles, namely inspection, disassembly / assembly and testing. The scope of the analysis, therefore, may be divided into multi-level skills depending upon company policies which would result in graduates being required to perform only a portion of the tasks listed in the analysis, while in other instances they would perform all of them.

This occupation occurs primarily in power plant shops of larger airlines, independent repair and overhaul shops and the repair and overhaul shops of engine manufacturers.

 

Certification Requirements

To qualify for certification with CCAA, the applicant must possess the necessary knowledge and skills and have acquired a minimum of thirty-six (36) months in the occupation.
