Aircraft Modifications & Upgrades

There are many different modifications available for your aircraft. Some may be made mandatory by EASA, FAA or the aircraft manufacturer, but the improvement of performance, reliability or ease of operation may also be a good reason to perform a modification on your aircraft.


Examples of mandatory modifications are mode “S” transponders, 8.33 kHz radios, RVSM systems, TCAS systems, IFR equipment or EASA and/or FAA Airworthiness Directives.


There are also numerous optional modifications available for most aircraft. When you have specific wishes concerning modifications on your aircraft, like GPS or autopilot systems, compliance with the applicable regulations is essential. Should your specific modification be not yet approved, we can set up and manage the approval process, making sure that your aircraft is compliant with the regulations.
