Accidents & Serious Incidents involving B741

  • B741, en-route, East Moriches NY USA, 1996 (On 17 July 1996, a Boeing 747, operated by TWA, experienced an in-flight breakup and then crashed into the Atlantic Ocean near East Moriches, New York, USA.)
  • B741, en-route, Gunma Japan 1985 (On August 12, 1985 a Boeing 747 SR-100 operated by Japan Air Lines experienced a loss of control attributed to loss of the vertical stabiliser. After the declaration of the emergency, the aircraft continued its flight for 30 minutes and subsequently impacted terrain in a mountainous area in Gunma Prefecture, Japan.)
  • B741, en-route, Pacific Ocean, 1997 (On 28th December 1997, a Boeing 747-100 being operated by United Airlines, which had departed from Tokyo for Hawaii, encountered severe turbulence thought to have been associated with a Jet Stream over the Pacific Ocean.)
  • B741, vicinity London Heathrow UK, 1997 (On 6 December 1997, a British Airways Boeing 747-100, departing from London Heathrow airport, had an engine bird strike just after take off, causing substantial damage and falling debris.)
  • 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.)
