Saudia Flight 162

Saudia Flight 162 was a scheduled flight from Jeddah, Saudi Arabia, to Karachi, Pakistan, with a stopover in Dhahran, Saudi Arabia. On 23 December 1980, the Lockheed L-1011 TriStar suffered a high-altitude uncontrolled decompression above international waters off Qatar, killing two children who were among the 271 passengers.

This was the second accident involving a Saudia TriStar in four months after Saudia Flight 163, the sister ship to HZ-AHJ operated by L-1011 HZ-AHK, burned after an emergency landing at Riyadh International Airport, killing all 301 aboard.

Accident

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 exited the aircraft 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 which 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. Their bodies were never found.

The explosion caused a loss of hydraulic fluid in systems A and B, the failure of the No. 2 engine power generator, and the detachment of the left main landing gear door. The flight crew manually deployed the oxygen masks, and Captain Zaghaba took control. An emergency descent was initiated with the 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 constantly turn to the left, using the ailerons, 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.

Despite the damage, the landing gear extended normally and the aircraft made a successful landing at 02:48. Zaghaba taxied the aircraft to an apron, where he shut down engines 1 and 3. Doors L1 and L2 were opened, but the evacuation slides did not inflate due to the failed generator on engine 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.
