After stopping, the aircraft slowly tilted backwards because the body gear had been ripped off or disabled on takeoff. The aircraft came to rest on its tail with its nose elevated. Until the accident, it was not known that the 747 would tilt backwards without the support of the main body gear.
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
The proposed models would have combined the 747's fuselage with a new wing spanning 251 feet (77 m) derived from the 777. Other changes included adding more powerful engines and increasing the number of tires from two to four on the nose landing gear and from 16 to 20 on the main landing gear. [242]
China Airlines Flight 006 was a daily non-stop international passenger flight from Taipei to Los Angeles International Airport.On February 19, 1985, the Boeing 747SP operating the flight was involved in an aircraft upset accident, following the failure of the No. 4 engine, while cruising at 41,000 ft (12,500 m).
On August 4, 1983, Pan Am Flight 73, a 747-100, struck a VASI light installation and its concrete base landing at Karachi International Airport, causing the nose gear to collapse backwards and to the left, resulting in total destruction of the VASI light installation and damage to the forward cargo hold, floor of the first class section, and ...
A Delta Air Lines flight landed with its “nose landing gear up” at Charlotte Douglas International Airport in North Carolina on Wednesday morning, the FAA says.
Wheel-well stowaways have been widely covered in the press and media at large throughout the history of passenger airlines.One of the most notable incidents involved Keith Sapsford (14) from Sydney, Australia, who fell 200 feet (60 m) to his death from the wheel-well of a Tokyo-bound Japan Air Lines Douglas DC-8 on February 24, 1970, shortly after takeoff from Sydney Kingsford Smith Airport.
