Lees Avionics has been providing top quality installation and maintenance services for light aircraft and helicopter owners since 1991. Since then the company has grown significantly and is now based in modern premises at Wycombe Air Park in Buckinghamshire. At this facility we undertake our design work, parts provisioning, technical support activities and can accommodate a wide range of aircraft for avionic replacement and upgrades. We are an authorised dealer for most of the major avionics equipment manufacturers.

Lees Avionics is an EASA Part 21J design approved organisation (Approval no: EASA.21J.174) and such has the capability to produce in-house modifications on aeroplanes and rotorcraft up to 15,000 kg MTWA and 6,000 kg MTWA respectively. Above these weights, modifications are undertaken in conjunction with a partner company. We can design, submit and certify minor and major avionics modifications to meet your individual requirements. If you have a foreign registered aircraft, we work with Designated Engineering Representatives to achieve the certification requirements of different authorities.
