Porta Air Service GmbH & Co KG

Porta Air Service GmbH & Co KG is an aircraft maintenance company based at Porta Westfalica airport, EDVY, in Germany. It is an EASA and FAA Part 145 approved repair station. The company says its story began in 1965 and that it has kept aircraft flying for over 60 years.

Porta focuses on turboprop and piston aircraft. It services and upgrades everything from a Cessna 172 to a King Air 200. The company lists authorised expertise for the King Air series, TBM, Piper Meridian and JetProp, Cessna 208 Caravan and Mooney aircraft. Maintenance and inspection cover general aviation aircraft of this kind.

Avionics is a major service. Porta is a Garmin Platinum Dealer and an authorised installer. It fits the full Garmin range, from autopilots and GTN navigators to full glass panel retrofits. The company says its in-house avionics team performs and certifies each installation. Its news page reports a Garmin Platinum Dealer award in September 2026.

Porta also rebuilds aircraft, taking them from a bare airframe to first flight. A 2026 project is a full rebuild of a 1987 Beechcraft Bonanza F33A. The shop works with most major aviation insurers on damage assessment, structural repair and return to service.

Special upgrades include BRS whole-aircraft parachute systems, TKS ice protection, Blackhawk engine conversions and Wipaire floats. The company installs, inspects and supports these systems.

For PT6 engines, Porta offers hot section inspections and borescope inspections. A hot section inspection checks the parts that see the highest heat for wear, cracking and heat damage. A borescope inspection looks inside the engine without a full teardown and gives documented findings.

The team has over 25 aviation experts, and many are pilots. Customers talk directly to the person working on their aircraft. Porta describes itself as specialised in turboprops and pistons, independent and personal. Before work starts, it gives a time estimate and a written quote. The company has news and careers pages.
