Which avionics brands do you install?

Garmin as an Authorized Dealer, plus Electronics International, Dynon, Aspen Avionics, Mid-Continent Instruments and uAvionix, and we install and support Avidyne, JPI and PS Engineering equipment. Each brand has its own page under Brands with what we do for it.

What does a Garmin panel upgrade cost and how long does it take?

It depends on the aircraft and the equipment. A GFC 500 autopilot or a single GTN navigator is typically a few days on the floor; a full TXi or G1000 NXi retrofit is measured in weeks. We give a written estimate with a schedule before any work starts, and apply any current Garmin promotion that fits.

Do you do the transponder and pitot-static checks after an install?

Yes. Islander holds limited instrument and radio ratings for FAR 91.411, 91.413 and 91.225 certifications on the makes in our FAA capability list, so the required checks after an ADS-B or transponder installation are done here under our Part 145 certificate. The installation itself is repair-station work on the listed airframes (Beechcraft, Piper PA-28, Cessna 208, Cirrus, Diamond, Epic) and Part 91 work by our certificated mechanics on everything else.

Can you install equipment I bought online?

Call us first. Dealer-installed Garmin equipment carries the full warranty and qualifies for Garmin rebates; equipment bought elsewhere often does not, and some items are dealer-only.

Part 145 and Part 91 — who signs the work

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.
