Unit of competency
Modification History
Release 2. Equivalent to MEA390 Repair and/or overhaul rotary wing dynamic components with amended prerequisite codes.
Application
This unit of competency requires application of hand skills, theory knowledge and maintenance publication procedures to repair and overhaul rotary wing dynamic components during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.
Applications include rotor assemblies and components, transmissions, drive shafts and couplings from piston and turbine engine rotary wing aircraft.
The unit is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. It is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
