As the Leaders in Managed Aircraft Maintenance Services, Sigma Aerospace’s Avionics team are specialists at installing, modifying, and repairing Avionics systems.



Avionics Maintenance

From scheduled avionic maintenance of a single aircraft through to a fleet wide upgrade of avionics systems, Sigma has the capability to manage this in house or, if more convenient, at your own location.

Our World class reputation has allowed us to complete major avionics upgrades on various aircraft including a fleet of corporate jets in long term contract, a fixed price ADSB upgrade of 18 turboprop aircraft (50 and 70 seat), as well as various upgrades to general aviation aircraft.

Whether a single engine aircraft or a fleet of aircraft, all work is quoted and you can be sure you will be kept fully informed through our first class service process. We deliver on time and budget.
