  • AS55, vicinity Fairview Alberta Canada, 1999 (Synopsis: 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.)
  • AT43, vicinity Geneva Switzerland, 2006 (Synopsis: On 29 March 2006 at about 1 mile from touchdown when in VMC on a night approach to destination Geneva, an ATR 42-300 being operated by Farnair on a cargo flight experienced a sudden electrical fire in the flight deck and an emergency was declared to ATC. Despite this situation the aircraft was able to land normally and vacate the runway via an RET after which it was forced to stop.)
  • AT76, en-route, east of Cork Ireland, 2016 (Synopsis: On 24 August 2016, an ATR 72-600 experienced a static inverter failure which resulted in smoke and fumes which were identifiably electrical. Oxygen masks were donned, a MAYDAY declared and after the appropriate procedures had been followed, the smoke / fumes ceased. The Investigation noted a long history of capacitor failures affecting this unit which continued to be addressed by successive non-mandatory upgrades including another after this event. However, it was also found that there was no guidance on the re-instatement of systems disabled during the initial response to such events, in particular the total loss of AC electrical power.)
  • B462, Cape Town South Africa, 2009 (Synopsis: On 19 March 2009 a BAe 146-200 being operated by South African Airlink on a scheduled passenger flight from George to Cape Town in day VMC experienced a flameout of all four engines during the landing roll at Cape Town. The aircraft had enough momentum to roll forward on the runway and vacate onto a taxiway and the APU continued to provide electrical power to the hydraulic system, which facilitated braking and directional control. It was then towed from the taxiway to the apron and the passengers disembarked normally.)
  • B732, vicinity Tamanrassat Algeria, 2003 (Synopsis: On 6 March 2003, a Boeing 737-200 being operated by Air Algerie had just become airborne during a daylight departure when the left hand engine suddenly failed just after the PF had called for “gear up”. Shortly afterwards, the aircraft commander, who had been PNF for the departure, took control but the normal pitch attitude was not reduced to ensure that a minimum airspeed of V2 was maintained and landing gear was not retracted. The aircraft lost airspeed, stalled and impacted the ground approximately 1nm from the point at which it had become airborne. A severe post crash fire occurred and the aircraft was destroyed and all on board except one passenger, were killed.)
  • B734, en-route, eastern England UK, 2018 (Synopsis: On 12 October 2018, the crew of a Boeing 737-400 already released to service under MEL conditions with an inoperative No 1 engine generator encountered a loss of services from the No 2 electrical system en-route to East Midlands which created a situation not addressed by QRH procedures. The flight was completed and both the new and existing defects were subsequently rectified relatively easily. The Investigation concluded that the operator involved appeared to be prioritising operational requirements over aircraft serviceability issues and made a range of Safety Recommendations aimed at improving company safety culture and the effectiveness of regulatory oversight.)
