What we doMaintenance
We fix what we fly. And what you fly.
Base maintenance at Altenrhein, line maintenance worldwide, and engineers who travel.
The short version
Our hangar at St. Gallen–Altenrhein (LSZR) maintains, repairs, modifies and rebuilds Twin Otters and other utility turboprops, both ours and our customers'. When the aircraft can't come to Altenrhein, the engineers go to the aircraft.
