A selection of articles in SKYbrary relating to events which included Human Factors as a contributory factor.

  • A109, vicinity London Heliport London UK, 2013 (On 16 January 2013, an Augusta 109E helicopter positioning by day on an implied (due to adverse weather conditions) SVFR clearance collided with a crane attached to a tall building under construction. It and associated debris fell to street level and the pilot and a pedestrian were killed and several others on the ground injured. It was concluded that the pilot had not seen the crane or seen it too late to avoid whilst flying by visual reference in conditions which had become increasingly challenging. The Investigation recommended improvements in the regulatory context in which the accident had occurred.)
  • A124, Zaragoza Spain, 2010 (On 20 April 2010, the left wing of an Antonov Design Bureau An124-100 which was taxiing in to park after a night landing at Zaragoza under marshalling guidance was in collision with two successive lighting towers on the apron. Both towers and the left wingtip of the aircraft were damaged. The subsequent investigation attributed the collision to allocation of an unsuitable stand and lack of appropriate guidance markings.)
  • A139 / A30B, Ottawa Canada, 2014 (On 5 June 2014, an AW139 about to depart from its Ottawa home base on a positioning flight exceeded its clearance limit and began to hover taxi towards the main runway as an A300 was about to touch down on it. The TWR controller immediately instructed the helicopter to stop which it did, just clear of the runway. The A300 reached taxi speed just prior to the intersection. The Investigation attributed the error to a combination of distraction and expectancy and noted that the AW139 pilot had not checked actual or imminent runway occupancy prior to passing his clearance limit.)
  • A306 / B744, vicinity London Heathrow UK, 1996 (On 5 April 1996 a significant loss of separation occurred when a B744, taking off from runway 27R at London Heathrow came into conflict to the west of Heathrow Airport with an A306 which had carried out a missed approach from the parallel runway 27L. Both aircraft were following ATC instructions. Both aircraft received and correctly followed TCAS RAs, the B744 to descend and the A306 to adjust vertical speed, which were received at the same time as corrective ATC clearances.)
  • A306, East Midlands UK, 2011 (On 10 January 2011, an Air Atlanta Icelandic Airbus A300-600 on a scheduled cargo flight made a bounced touchdown at East Midlands and then attempted a go around involving retraction of the thrust reversers after selection out and before they had fully deployed. This prevented one engine from spooling up and, after a tail strike during rotation, the single engine go around was conducted with considerable difficulty at a climb rate only acceptable because of a lack of terrain challenges along the climb out track.)
  • A306, Paris CDG France, 1997 (On 30 July 1997, an Airbus A300-600 being operated by Emirates Airline was departing on a scheduled passenger flight from Paris Charles de Gaulle in daylight when, as the aircraft was accelerating at 40 kts during the take off roll, it pitched up and its tail touched the ground violently. The crew abandoned the takeoff and returned to the parking area. The tail of the aircraft was damaged due to the impact with the runway when the plane pitched up.)
  • A306, Stockholm Sweden, 2010 (On 16 January 2010, an Iran Air Airbus A300-600 veered off the left side of the runway after a left engine failure at low speed whilst taking off at Stockholm. The directional control difficulty was attributed partly to the lack of differential braking but also disclosed wider issues about directional control following sudden asymmetry at low speeds. The Investigation concluded that deficiencies in the type certification process had contributed to the loss of directional control. It was concluded that the engine malfunction was due to the initiation of an engine stall by damage caused by debris from a deficient repair.)
  • A306, vicinity Birmingham AL USA, 2013 (On 14 August 2013, a UPS Airbus A300-600 crashed short of the runway at Birmingham Alabama on a night IMC non-precision approach after the crew failed to go around at 1000ft aal when unstabilised and then continued descent below MDA until terrain impact. The Investigation attributed the accident to the individually poor performance of both pilots, to performance deficiencies previously-exhibited in recurrent training by the Captain and to the First Officer's failure to call in fatigued and unfit to fly after mis-managing her off duty time. A Video was produced by NTSB to further highlight human factors aspects.)
  • A306, vicinity JFK New York USA, 2001 (On November 12, 2001, an Airbus Industries A300-600 operated by American Airlines crashed into a residential area of Belle Harbour, New York, after take-off from John F. Kennedy International Airport, New York. Shortly after take off, the aircraft encountered mild wake turbulence from a departing Boeing 747-400.)
  • A306, vicinity London Gatwick, 2011 (On 12 January 2011, an Airbus A300-600 being operated by Monarch Airlines on a passenger flight from London Gatwick to Chania, Greece experienced activations of the stall protection system after an unintended configuration change shortly after take off but following recovery, the flight continued as intended without further event. There were no abrupt manoeuvres and no injuries to the 347 occupants.)
  • A306, vicinity Nagoya Japan, 1994 (On 26 April 1994, the crew of an Airbus A300-600 lost control of their aircraft on final approach to Nagoya and the aircraft crashed within the airport perimeter. The Investigation found that an inadvertent mode selection error had triggered control difficulties which had been ultimately founded on an apparent lack understanding by both pilots of the full nature of the interaction between the systems controlling thrust and pitch on the aircraft type which were not typical of most other contemporary types. It was also concluded that the Captain's delay in taking control from the First Officer had exacerbated the situation.)
  • A30B, en-route, Bristol UK, 2000 (On 27 June 2000 an Airbus A300-600 being operated by American Airlines on a scheduled passenger service from London Heathrow to New York JFK was being flown manually in the day VMC climb and approaching FL220 when a loud bang was heard and there was a simultaneous abrupt disturbance to the flight path. The event appeared to the flight crew to have been a disturbance in yaw with no obvious concurrent lateral motion. Although following the disturbance, the aircraft appeared to behave normally, the aircraft commander decided to return to London Heathrow rather than commence a transatlantic flight following what was suspected to have been an un-commanded flight control input. An uneventful return was made followed by an overweight landing 50 minutes after take off.)
