Description

Non Revenue Flights have often been identified as attracting a greater risk of an accident or serious incident than the revenue flights which form the main business of any operator of commercial aircraft. In many respects, the causes of increased risk for this type of flight are similar to those which have been associated with a slightly wider sub group of flights - Non Standard Flights.

Accident & Incident Reports

A selection of accidents and events which have occurred on non-revenue flights:

  • A320, vicinity Perpignan France, 2008 (LOC HF AW) (On 27 November 2008, an A320 operated by XL Airways Germany, crashed into the sea at Canet Plage, France, following loss of control, without recovery, during a low speed handling test attempted at low altitude as part of a function flight.)
  • AS32 / B734, Aberdeen UK, 2000 (AGC RI HF) (For reasons that were not established, a Super Puma helicopter being air tested and in the hover at about 30 feet agl near the active runway at Aberdeen assumed that the departure clearance given by GND was a take off clearance and moved into the hover over the opposite end of the runway at the same time as a Boeing 737 was taking off. The 737 saw the helicopter ahead and made a high speed rejected take off, stopping approximately 100 metres before reaching the position of the helicopter which had by then moved off the runway still hovering.)
  • AS3B, en route, northern North Sea UK, 2008 (LOC WX AW HF) (On 22 February 2008, a Eurocopter AS332 L2 Super Puma flying from an offshore oil platform to Aberdeen was struck by lightning. There was no apparent consequence and so, although this event required a landing as soon as possible, the commander decided to continue the remaining 165nm to the planned destination which was achieved uneventfully. Main rotor blade damage including some beyond repairable limits was subsequently discovered. The Investigation noted evidence indicating that this helicopter type had a relatively high propensity to sustain lightning strikes but noted that, despite the risk of damage, there was currently no adverse safety trend.)
  • AS3B, vicinity Den Helder Netherlands, 2006 (LOC HF AW) (On 21 November 2006, the crew of a Bristow Eurocopter AS332 L2 making an unscheduled passenger flight from an offshore platform to Den Helder in night VMC decided to ditch their aircraft after apparent malfunction of an engine and the flight controls were perceived as rendering it unable to safely complete the flight. All 17 occupants survived but the evacuation was disorganised and both oversight of the operation by and the actions of the crew were considered to have been inappropriate in various respects. Despite extensive investigation, no technical fault which would have rendered it unflyable could be confirmed.)
  • AS55, vicinity Fairview Alberta Canada, 1999 (AW HF FIRE) (On 28th April 1999, an AS-355 helicopter suffered an in-flight fire attributed to an electrical fault which had originated from a prior maintenance error undetected during incomplete pre-flight inspections. The aircraft carried out an immediate landing allowing evacuation before the aircraft was destroyed by an intense fire.)
