Accidents & Serious Incidents involving AS50

  • AS50 / PA32, en-route, Hudson River NJ USA, 2009 (LOS HF) (On August 8, 2009 a privately operated PA32 and a Eurocopter AS350BA helicopter being operated by Liberty Helicopters on a public transport sightseeing flight collided in VMC over the Hudson River near Hoboken, New Jersey whilst both operating under VFR. The three occupants of the PA32, which was en route from Wings Field PA to Ocean City NJ, and the six occupants of the helicopter, which had just left the West 30th Street Heliport, were killed and both aircraft received substantially damaged.)
  • AS50, Dalamot Norway, 2011 (LOC HF FIRE) (On 4 July 2011, an Airlift Eurocopter AS 350 making a passenger charter flight to a mountain cabin in day VMC appeared to suddenly depart controlled flight whilst making a tight right turn during positioning to land at the destination landing site and impacted terrain soon afterwards. The helicopter was destroyed by the impact and ensuing fire and all five occupants were fatally injured. The subsequent investigation came to the conclusion that the apparently abrupt manoeuvring may have led to an encounter with ‘servo transparency’ at a height from which the pilot was unable to recover before impact occurred.)
  • AS50, en-route, Hawaii USA, 2005 (WX LOC HF) (On 23 September 2005, an AS350 helicopter, operated by Heli USA Airways, crashed into the sea off Hawaii following loss of control associated with flight into adverse weather conditions.)
