Accidents & Serious Incidents involving B742

  • B742 / A320, Frankfurt Germany, 2006 (On 12 January 2006, an Air China Boeing 747-200 which had just landed at Frankfurt failed to correctly understand and read back its taxi in clearance and the incorrect readback was not detected by the controller. The 747 then crossed another runway at night and in normal visibility whilst an A320 was landing on it. The A320 responded by increased braking and there was consequently no actual risk of collision. The controller had not noticed the incursion and, in accordance with instructions, all stop bars were unlit and the RIMCAS had been officially disabled due to too many nuisance activations.)
  • B742 / B741, Tenerife Canary Islands Spain, 1977 (On 27 March 1977, a KLM Boeing 747-200 began its low visibility take-off at Tenerife without requesting or receiving take-off clearance and a collision with a Boeing 747-100 backtracking the same runway subsequently occurred. Both aircraft were destroyed by the impact and consequential fire and 583 people died. The Investigation attributed the crash primarily to the actions and inactions of the KLM Captain, who was the Operator's Chief Flying Instructor. Safety Recommendations made emphasised the importance of standard phraseology in all normal radio communications and avoidance of the phrase "take-off" in ATC Departure Clearances.)
  • B742 / B744, Chicago O'Hare IL USA, 1999 (On 1 April 1999, an Air China Boeing 747-200F which had just landed on and cleared runway 14R at Chicago O’Hare failed to follow its correctly read back taxi-in clearance and crossed the landing runway at night ahead of a Boeing 747 taking off. The latter rotated abruptly and banked away from the taxiing 747, missing it by an estimated 75 feet. It was found that the Air China aircraft had realised it was going the wrong way but had slowed rather than stopped taxiing with the nose of the aircraft past the runway centreline as it was overflown.)
  • B742, Brussels Belgium, 2008 (On 25 May 2008 a Kalitta Air B747-200F, which was departing Brussels on a cargo flight to Bahrain, overran Runway 20 at Brussels Airport, Belgium during a rejected take-off. The aircraft came to a stop 300m beyond the end of runway 20 and broke into three parts. The crew of four and one passenger safely evacuated from the aircraft and suffered only minor injuries.)
  • B742, Düsseldorf Germany, 2005 (On 24 January 2005, an Atlas Air Boeing 747-200F overran the end of the landing runway at Düsseldorf after runway braking action notified just prior to landing as medium due to snowfall unexpectedly deteriorated after the snowfall intensified. The overrun led to collision with ground obstacles and engines 2 and 3 caught fire. Escape slide malfunction at the forward left hand door led to an alternative non standard crew evacuation route being used. Significant damage to the aircraft resulted in it being declared a hull loss. The Investigation took almost 8 years to complete and publish.)
  • B742, Halifax Canada, 2004 (On 14 October 2004, a B742 crashed on take off from Halifax International Airport, Canada, and was destroyed by impact forces and a post-crash fire. The crew had calculated incorrect V speeds and thrust setting using an EFB.)
  • B742, Montreal Canada, 2000 (On 23 July 2000, a Boeing 747-200 being operated by Royal Air Maroc on a scheduled passenger flight from New York to Montreal overran the temporarily restricted available landing runway length after the aircraft failed to decelerate sufficiently during a daylight landing with normal on-ground visibility. It struck barriers at the displaced runway end before stopping 215 metres further on. Shortly before it stopped, ATC observed flames coming out of the No. 2 engine and advised the flight crew and alerted the RFFS. However, no sustained fire developed and the aircraft was undamaged except for internal damage to the No 2 engine. No emergency evacuation was deemed necessary by the aircraft commander and there were no occupant or other injuries)
  • B742, Sokoto Nigeria, 2013 (On 4 October 2013, a Boeing 747-200 touched down short of the intended landing runway at Sokoto after the Captain opted to reduce track miles by making a direct visual contact approach in dark night calm wind conditions rather than continuing as initially cleared towards an ILS approach in the reciprocal runway direction. The Investigation was hampered by an inoperative FDR and failure to preserve relevant CVR data on the grounded aircraft and concluded that the decision to make a visual approach rather than an ILS approach when the VASI was out of service for both runways was inappropriate.)
  • B742, Stockholm Arlanda Sweden, 2007 (On 25 June 2007, a Boeing 747-200F being operated by Cathay Pacific on a scheduled cargo flight from Stockholm to Dubai had completed push back for departure in normal daylight visibility and the parking brakes had been set. The tow vehicle crew had disconnected the tow bar but before they and their vehicle had cleared the vicinity of the aircraft, it began to taxi and collided with the vehicle. The flight crew were unaware of this and continued taxiing for about 150 metres until the flight engineer noticed that the indications from one if the engines were abnormal and the aircraft was taxied back to the gate. The tow vehicle crew and the dispatcher had been able to run clear and were not injured physically injured although all three were identified as suffering minor injury (shock). The aircraft was “substantially damaged” and the tow vehicle was “damaged”.)
  • B742, en-route, Mount Galunggung Indonesia, 1982 (On 24 June 1982, a British Airways Boeing 747-200 lost power on all four engines while flying at night at FL370 en route from Kuala Lumpur to Perth. During the ensuing sixteen minutes, the aircraft descended without power from FL370 to FL120, at which point the flight crew were able to successfully restart engines one, two and four after which an en route diversion was made to Jakarta.)
  • B742, en-route, Penghu Island Taiwan, 2002 (On 25 May 2002, a China Airlines Boeing 747-200 broke up in mid air, over Penghu Island Taiwan, following structural failure as a result of an improper repair in 1980, which had not been detected by subsequent inspections.)
  • B742, vicinity Stansted UK, 1999 (On 22 December 1999, a KAL Boeing 747 freighter crashed shortly after take-off from Stansted UK, following an ADI malfunction.)
