Part 145 and Part 91 — who signs the work
Under our Part 145 certificate on this page: Lycoming O-320, O-360, O-540 and IO-360-M1A series — annual, 100-hour and periodic inspections; powerplant inspection, minor repair and minor alteration under the limited engine rating. Not under the certificate: engine overhaul.
Islander Aviation (BMV Air Center LLC) is an FAA Part 145 repair station, certificate 6KFR481C, with limited airframe, engine, instrument and radio ratings. Our FAA-accepted Capability List (Rev. 8, 29 September 2026) covers airframe inspections, repairs and alterations on Beechcraft, Piper, Cessna, Cirrus, Diamond Aircraft, Epic Aircraft aircraft; inspections and minor repair of Lycoming, Continental, Austro Engine, Pratt & Whitney Canada engines; and pitot-static, transponder, ADS-B and ELT certifications on the listed makes. Overhauls are not performed under the certificate.
Anything not covered under our Part 145 capability list — King Air, Citation and Pilatus airframes, for example — is still performed by Islander Aviation, as Part 91 maintenance signed off by our FAA-certificated A&P and IA mechanics. Engine overhauls are coordinated with a specialist engine shop.
