Accidents & Serious Incidents involving MD11

  • MD11, Dublin Ireland, 2002 (On 3 February 2002, a Delta Airlines MD-11 encountered a sudden exceptional wind gust (43 kts) during the landing roll at Dublin, Ireland. The pilot was unable to maintain the directional control of the aircraft and a runway excursion to the side subsequently occurred.)
  • MD11, Hong Kong China, 1999 (On 22 August 1999, a Boeing MD11 being operated by China Airlines on a scheduled passenger flight from Taipei to Hong Kong carried out a normal ILS approach to Runway 25 Left in a strong crosswind and some turbulence but the night landing on a wet runway surface in normal visibility was very hard after a high sink rate in the flare was not arrested. The right main landing gear collapsed, the right wing separated from the fuselage and the aircraft caught fire and became inverted and reversed ending up on the grass to the right of the runway. Rapid attendance by the RFFS facilitated the escape of most of the 315 occupants but there were 3 deaths and 50 serious injuries as well as 153 minor injuries. The aircraft was destroyed.)
  • MD11, New York JFK USA, 2003 (A McDonnell Douglas MD11F failed to complete its touchdown on runway 04R at New York JFK until half way along the 2560 metre-long landing runway and then overran the paved surface by 73 metres having been stopped by the installed EMAS. The Investigation found no evidence that the aircraft was not serviceable and noted that the and that the landing had been attempted made with a tailwind component which meant that the runway was the minimum necessary for the prevailing aircraft landing weight.)
  • MD11, Riyadh Saudi Arabia, 2010 (On 27 July 2010, a Boeing MD11F being operated by Lufthansa Cargo on a scheduled flight from Frankfurt to Riyadh bounced twice prior to a third hard touchdown whilst attempting to land on 4205 metre-long Runway 33L at destination in normal day visibility. The fuselage was ruptured and, as the aircraft left the side of the runway, the nose landing gear collapsed and a fire began to take hold. A ‘MAYDAY’ call was made as the aircraft slid following the final touchdown. Once the aircraft had come to a stop, the two pilots evacuated before it was largely destroyed by fire. One pilot received minor injuries, the other injuries described as major.)
  • MD11, en-route, Atlantic Ocean near Halifax Canada, 1998 (On 2 September 1998, an MD-11 aircraft belonging to Swissair, crashed into the sea off Nova Scotia following an in-flight electrical fire.)
  • MD11, en-route, near Cape Ashizuri, Japan, 2007 (On 10 January 2007, a Transmile Air Services Boeing MD11F First Officer became suddenly incapacitated by seizure during a flight from Anchorage to Hong Kong. A diversion was made and the affected pilot hospitalised where the cause was identified as a previously non-symptomatic brain tumour.)
  • MD11, vicinity East Midlands UK, 2005 (On 3 December 2005, the crew of a MD-11 freighter failed to set the (very low) QNH for a night approach, due to distraction, and as a result descended well below the cleared altitude given by ATC for the intercept heading for the ILS at Nottingham East Midlands airport, UK.)
  • MD82 / MD11, Anchorage AK USA, 2002 (On 17 March 2002, at Ted Stevens Anchorage Airport, a McDonnell Douglas MD82 operated by Alaska Airlines, on a night pushback in snow conditions collided with an inbound taxiing McDonnell Douglas MD-11. The MD82 suffered substantial rudder damage although the impacting MD11 winglet was undamaged.)
