On August 24, 2003, about 1110 eastern daylight time, a Boeing 757-223, N609AA, operated by American Airlines Inc. as flight 1163, a Title 14 CFR Part 121 scheduled domestic passenger flight, had a failure of the left main landing gear truck beam, while taxiing for takeoff at Miami International Airport, Miami, Florida. Visual meteorological conditions prevailed. An instrument flight rules flight plan was filed. The airplane received minor damage. The two airline transport-rated pilots, four flight attendants, and 163 passengers reported no injuries. The flight was originating at the time, and was en route to Chicago, Illinois.
The flight had departed the gate and was taxiing on taxiway M4, at about 5-10 knots, when the airplane yawed and tilted to the left, and then stopped. Another pilot advised that there appeared to be a problem with the left gear. The airplane was shut down, the passengers and crew exited the airplane through door L1, using stairs. Examination of the left main landing gear reveled that the truck beam, part number 161N1611-6, serial number 16PE2, had a circumferential fracture 14 inches forward of the aft 2 wheels, and had separated into 2 pieces. The truck beam had been in service since the airplane was new in 1996, and had accumulated 7,517 cycles. The service life on this part is 12,000 cycles or 10 years which ever came first.
