  • A320, vicinity Perth Australia, 2015 (Synopsis: On 12 September 2015, an Airbus A320 autopilot and autothrust dropped out as it climbed out of Perth and multiple ECAM system messages were presented with intermittent differences in displayed airspeeds. During the subsequent turn back in Alternate Law, a stall warning was disregarded with no actual consequence. The Investigation attributed the problems to intermittently blocked pitot tubes but could not establish how this had occurred. It was also found that the priority for ECAM message display during the flight had been inappropriate and that the key procedure contained misleading information. These ECAM issues were subsequently addressed by the aircraft manufacturer.)
  • A321, Manchester UK, 2008 (1) (Synopsis: On 18 July 2008, an Airbus A321-200 operated by Thomas Cook Airlines experienced hard landing during night line training with significant aircraft damage not found until several days later. The hard landing was subsequently partially attributed to the inability to directly observe the trainee pitch control inputs on side stick of the A321.)
  • A321, Manchester UK, 2008 (2) (Synopsis: On 28 July 2008, the crew flying an Airbus A321-200 departing Manchester UK were unable to raise the landing gear. The fault was caused by damage to the Nose Landing Gear sustained on the previous flight which experienced a heavy landing.)
  • A321, en-route, Northern Sudan, 2010 (Synopsis: On 24 August 2010, an Airbus A321-200 being operated by British Midland on a scheduled public transport service from Khartoum to Beirut experienced, during cruise at FL360 in night IMC, an electrical malfunction which was accompanied by intermittent loss of the display on both pilots’ EFIS and an uncommanded change to a left wing low attitude. De-selection of the No 1 generator and subsequent return of the rudder trim, which had not previously been intentionally moved, to neutral removed all abnormalities and the planned flight was completed without further event with no damage to the aircraft or injuries to the 49 occupants.)
  • 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.)
  • A332, vicinity Brisbane Australia, 2013 (Synopsis: On 21 November 2013, an A330 rejected its take off from Brisbane after an airspeed indication failure. Following maintenance intervention, a similar airspeed indication fault on the subsequent departure was reported to have been detected after V1. Once airborne, reversion to Alternate Law occurred and slat retraction failed. After an air turnback, it was discovered that the cause of both events was blockage of the No. 1 Pitot Head by a mud-dauber wasp nest which was created during the initial two hour turnround at Brisbane. Investigation of a 2014 event to a Boeing 737 at Brisbane with exactly the same causation was noted.)
