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 children who were among the 271 passengers.[2][3][1]
This was the second accident involving a Saudia Lockheed L-1011 Tristar in four months, after Saudia Flight 163 burned down after an emergency landing at Riyadh International Airport, killing all 301 aboard.[4]
Aircraft and crew[edit]
The accident aircraft was a Lockheed L-1011-200 TriStar, registration HZ-AHJ (S/N 1161) was delivered to Saudia in 1979.[1][5][6]
There were three crew members in the flight deck. The captain, Fouad Zaghaba;[7] the first officer; and the flight engineer were certified for the flight and had received adequate training.[2]: 159

The aircraft took off from Jeddah at 22:30 local time and landed without incident in Dhahran at 00:29, where the aircraft was refueled, 60 passengers deplane and 87 passengers boarded. After takeoff at 01:51, the aircraft was cleared to an altitude of 33,000 feet. As it climbed through 29,000 ft, one of its main wheel tires failed, exploding and creating a hole in the fuselage and cabin floor. Debris of metal and tire rubber were flung through the cabin and injured several passengers. Two young passengers, a 14-year-old girl and a 1½-year-old boy, were killed when they were ejected through the hole in the cabin floor.[2][1] Their bodies were never found. The explosion caused hydraulic systems A and B to lose fluid, the No. 2 (tail) engine power generator to failed, and the left main landing gear door to be ripped off. The flight crew manually deployed the oxygen masks deployed and captain Zaghaba took control. An emergency descent was initiated, followed by a decision to divert to Qatar's Doha International Airport. Bahrain Air Traffic Control handed control over to Doha, which cleared Flight 162 to land on runway 34. When the flap handle was set to 4°, the flaps did not extend and the captain reported that he needed to rotate the ailerons to the left to keep the aircraft in level flight on a stable heading. He elected to land with the flaps retracted and jettisoned 16 tons of fuel to reduce the aircraft's weight. During the descent, flight attendants calmed down the passengers calm and demonstrated the brace position. Despite the damage, the landing gear extended normally and the aircraft made a successful landing at 02:48. Captain Zaghaba taxied the aircraft to an apron, where he shut down engines no. 1 and 3 (left and right, respectively). Doors L-1 and L-2 aircraft doors were opened but the evacuation slides did not inflate due to the failed generator on engine no. 2. The flight engineer started the auxiliary power unit but it could not be connected to the busbar. Airstairs were brought up to the aircraft and the occupants disembarked. Five passengers sustained minor injuries and were hospitalized.
Investigation[edit]
The cockpit voice recorder (CVR) was overwritten and only contained conversations after the emergency landing. The flight data recorder malfunctioned and recorded erroneous data. As a result, both recorders were unusable. The probable cause of the accident 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.[1][8]
Aftermath[edit]
The aircraft was repaired and returned to service with Saudia.[1] It was retired in 1999 and later scrapped.[9]
