Integrated Aircraft Maintenance, Workforce and Training

Australia’s only fully integrated provider across aircraft maintenance, overhaul, workforce and engineer training.

Sigma Aerospace Group brings together commercial aircraft maintenance, engine overhaul, component overhaul and parts, aviation workforce solutions, and aircraft engineer training under one operating model.

That matters because aircraft downtime, engineer shortages and licence bottlenecks usually do not happen in isolation. Sigma’s structure is built to connect the aircraft, the people and the training to enable us to deliver best-in-class tailored solutions for aircraft operators.

One integrated engineering solution delivering less friction between maintenance, workforce and training.
