Saudia Flight 162 was a scheduled flight from Dhahran International Airport, Saudi Arabia to Karachi International Airport, Pakistan that suffered a high-altitude uncontrolled decompression, above international waters off Qatar, killing two of the 292 passengers and crew on board.
The accident aircraft was a Lockheed L-1011-200 TriStar, registration HZ-AHJ (c/n 1161).
Shortly after takeoff, as the aircraft reached an altitude of 29,000 feet during its climb, one of its main wheels failed inside the undercarriage bay, creating a hole in the fuselage and cabin floor. An emergency descent was initiated, followed by a successful landing at Qatar's Doha International Airport. Two passengers were killed when they were ejected through the hole in the cabin floor.
The probable cause of the incident was determined to be a fatigue failure of a flange on the hub of one of the main landing gear wheels. This failure had resulted in one of the tires blowing out. The debris from this explosion had penetrated the cabin of the airplane, causing the explosive decompression. B.F. Goodrich Co. and Lockheed were found to share responsibility for their failure to assess safety hazards associated with this particular wheel design. In addition, the United States Federal Aviation Administration (FAA) was found to have had inadequate oversight of the manufacturers.
