Accidents & Serious Incidents involving GLF4

  • GLF4, Bedford MA USA, 2014 (On 31 May 2014, a Gulfstream IV attempted to take off with the flight control gust locks engaged and, when unable to rotate, delayed initiating the inevitable rejected take off to a point where an overrun at high speed was inevitable. The aircraft was destroyed by a combination of impact forces and fire and all seven occupants died. The Investigation attributed the accident to the way the crew were found to have habitually operated but noted that type certification had been granted despite the aircraft not having met requirements which would have generated an earlier gust lock status warning.)
  • GLF4, Berlin Tegel Germany, 2007 (A Gulfstream 4 departing from Berlin at night with good surface visibility prevailing was cleared to taxi onto the parallel runway beyond the one in use for landing because both the GND and TWR controllers had incorrectly assumed the original parking position of the aircraft. Upon approaching the runway crossing, the Gulfstream 4 crew recognised a stream of approaching aircraft and held clear whilst (with difficulty) alerting the TWR controller to their implied crossing clearance. At this point the controller recognised the ATC error.)
  • GLF4, Le Castellet France, 2012 (On 13 July 2012, a Gulfstream G-IV left the side of the runway at high speed during the landing roll at Le Castellet following a positioning flight after ineffective deceleration after the flight crew had forgotten to arm the ground spoilers. The Investigation found that pilot response to this situation had been followed by a loss of directional control, collision with obstructions and rapid onset of an intense fire. Contributory factors identified included poor procedural compliance by the pilots, their lack of training on a relevant new QRH procedure which Gulfstream had ineffectively communicated and ineffective FAA oversight of the operation.)
  • GLF4, Teterboro NJ USA, 2010 (On 1 October 2010, a Gulfstream G-IV being operated by General Aviation Flying Service as ‘Meridian Air Charter’ on a corporate flight from Toronto International to Teterboro made a deep landing on 1833m-long runway 06 at destination in normal day visibility and overran the end of the runway at a speed of 40 to 50 knots before coming to a stop 30m into a 122m long EMAS installation.)
  • GLF4, vicinity Kerry Ireland, 2009 (On 13 July 2009, a Gulfstream IV being operated by Indian operator Asia Aviation on a private flight from Kerry to Luton with one passenger on board in day IMC suffered a left main windshield failure shortly after take off and elected to make a return to land. Having received an ATC clearance to do so, it then failed to follow it and began a steep descent approximately 6 nm to the south of the airport towards high ground. When ATC became aware of this, an urgent instruction to climb was given and eventually the return was completed.)
