Metal fatigue and aircraft design flaw 6 Structural failure of the right horizontal stabiliser due to metal fatigue and aircraft design flaw 1978-06-26 Helikopter Service Flight 165: North Sea, Norway Sikorsky S-61: Fatigue 18 Rotor blade loosened after fatigue to the knuckle joint: crashed into the sea [10] 1979-05-25 American Airlines Flight 191
Having developed a suitable design for such an aircraft, development activity on the Lampyridae programme proceeded to the construction of a single three-quarter scale piloted model of the aircraft. [4] This model was initially used for a series of wind tunnel tests. Commenced during 1985, these tests are known to have involved at least two ...
The accident killed 48 people in all: 35 passengers and five crew members on board the aircraft, and seven occupants of the houses.There were 250 passengers and 13 crew who survived; however 37 passengers and crew and another 11 people on the ground were injured in the accident. The aircraft was damaged beyond repair and written off. [14]
All 151 people on board evacuated the aircraft via the evacuation slides and the aircraft was repaired. [ 34 ] On 28 August 2002, America West Airlines Flight 794, an Airbus A320-231 registered as N635AW, experienced thrust asymmetry while landing at Phoenix Sky Harbor International Airport and veered off the runway.
There are two generic types of aircraft structure, safe life and fail safe. The former is one that has low residual strength if a primary load-bearing member should fail, whereas the latter has alternative load paths so that if a primary load-bearing member cracks, residual strength remains because the loads can be assumed by adjacent members.
The aircraft used was a Boeing 727-200 purchased by the television production companies, registration XB-MNP [1] (formerly N293AS). [2] The site in Mexico was chosen because authorities in the United States would not allow the test to take place. [3] [4] The aircraft's original owner was Singapore Airlines. [5]
The aircraft was a Douglas DC-6, registration N37512, serial number 43001. The airframe had flown 22,068 flying hours, and had undergone an inspection 105 hours before the accident. The aircraft was powered by four Pratt & Whitney R2800-CB16 engines, fitted with Hamilton Standard 43E60-317 propellers. [5]
