China Airlines Flight 611 (2002): A Boeing 747-200B disintegrated in mid-air over the Taiwan Strait due to a structural failure caused by improper repairs made following a tailstrike 22 years earlier. [7] All 225 occupants on board were killed.
The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted a jet 2 + 1 ⁄ 2 times its size, to reduce its seat cost by 30%.
China Airlines Flight 006 (call sign "Dynasty 006") was a daily non-stop 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).
With a wing loading of 100 lb/sq ft (490 kg/m 2) the load factor is twice smaller and barely reaches 1g at 40,000 ft (12,000 m). [15] Aircraft with low wing loadings tend to have superior sustained turn performance because they can generate more lift for a given quantity of engine thrust.
Pratt & Whitney faced difficulties with the JT9D design during the Boeing 747 test program. Engine failures during the flight test program resulted in thirty aircraft being parked outside the factory with concrete blocks hanging from the pylons, awaiting redesigned engines. Boeing and Pratt & Whitney worked together in 1969 to solve the problem.
Qantas Flight 30, on 25 July 2008, a Boeing 747-438 operated by Qantas, construction number 25067, registration VH-OJK, was a scheduled flight from London Heathrow to Melbourne with a stopover in Hong Kong. The flight was interrupted on the Hong Kong leg by an exploding oxygen tank that ruptured the fuselage just forward of the starboard wing root.
An aerostructure is a component of an aircraft's airframe. This may include all or part of the fuselage, wings, or flight control surfaces.Companies that specialize in constructing these components are referred to as "aerostructures manufacturers", though many larger aerospace firms with a more diversified product portfolio also build aerostructures.
