Built in 2001, HB-ZDE flew with Air-Grischa till August of 2005, when it was sold to Rhein-Heli and based in Balzers (Lichtenstein) till July of 2012, when - unfortunately - Rhein-Heli together with many other traditional and standalone helicopter companies merged into Swiss Helicopter AG. Lichtenstein does not maintain its own aircraft registry, all its aircraft carry a HB-registration plus the flag of Lichtenstein instead of the Swiss cross required on Swiss aircraft.
