The A03 with the standard gearbox for NORMAL category aircraft, commuters and agricultural aircraft. The core design feature is regular operation, non-inverted, regular g-load considerations. This gearbox variant can be combined with the 500 and 550 hp power versions as well as high altitude mission layouts.
As the gearbox is integrating the oil management, this installation is needs less installation consideration and less 3rd party system integration.
A03 type design is certified in compliance to EASA CS-E / TYPE-CERTIFICATE-DATA-SHEET No.: E.150.
