  • A321, en-route, near Pamplona Spain, 2014 (Synopsis: On 5 November 2014, the crew of an Airbus A321 temporarily lost control of their aircraft in the cruise and were unable to regain it until 4000 feet of altitude had been lost. An investigation into the causes is continuing but it is already known that blockage of more than one AOA probe resulted in unwanted activation of high AOA protection which could not be stopped by normal sidestick inputs until two of the three ADRs had been intentionally deactivated in order to put the flight control system into Alternate Law.)
  • A332, en-route, Atlantic Ocean, 2009 (Synopsis: On 1 June 2009, an Airbus A330-200 being operated by Air France on a scheduled passenger flight from Rio de Janeiro to Paris CDG as AF447 exited controlled flight and crashed into the sea with the loss of the aircraft and all 228 occupants. It was found that the loss of control followed an inappropriate response by the flight crew to a transient loss of airspeed indications in the cruise which resulted from the vulnerability of the pitot heads to ice crystal icing.)
  • A333, en-route, south of Moscow Russia, 2010 (Synopsis: On 22 December 2010, a Finnair Airbus A330-300 inbound to Helsinki and cruising in very cold air at an altitude of 11,600 metres lost cabin pressurisation in cruise flight and completed an emergency descent before continuing the originally intended flight at a lower level. The subsequent Investigation was carried out together with that into a similar occurrence to another Finnair A330 which had occurred 11 days earlier. It was found that in both incidents, both engine bleed air systems had failed to function normally because of a design fault which had allowed water within their pressure transducers to freeze.)
  • A346, en-route, Amsterdam Netherlands, 2005 (Synopsis: On 8 February 2005, a Virgin Atlantic Airways A340-600 experienced in-flight fuel management problem which led to loss of power of No 1 engine and temporary power loss of No 4. The captain decided to divert to Amsterdam where the aircraft landed safely on three engines.)
  • A388, en-route, northern Afghanistan, 2014 (Synopsis: On 5 January 2014, an Airbus A380-800 en route to Singapore at night made an emergency descent and diversion to Baku after a loss of cabin pressure without further event. The Investigation attributed the pressure loss to a fatigue crack in a door skin which was initiated due to a design issue with door Cover Plates, which had not been detected when the Cover Plate was replaced with an improved one eighteen months earlier. Safety Issues related to cabin crew use of emergency oxygen and diversions to aerodromes with a fire category less than that normally required were also identified.)
  • AS32, en-route, near Peterhead Scotland UK, 2009 (Synopsis: On 1 April 2009, the flight crew of a Bond Helicopters’ Eurocopter AS332 L2 Super Puma en route from the Miller Offshore Platform to Aberdeen at an altitude of 2000 feet lost control of their helicopter when a sudden and catastrophic failure of the main rotor gearbox occurred and, within less than 20 seconds, the hub with the main rotor blades attached separated from the helicopter causing it to fall into the sea at a high vertical speed The impact destroyed the helicopter and all 16 occupants were killed. Seventeen Safety Recommendations were made as a result of the investigation.)
