New Delhi-Indira Gandhi

Flight PA073 was cleared to land on runway 25R of Karachi International Airport (KHI), Pakistan. The approach speed just prior to touchdown was 152 knots. After touchdown reverse thrust was applied on engines n°1, 2 and 3. Engine No.4 which had an unserviceable reverser was left in forward idle. Seventy knots was called and some three seconds later reverse power was decreased. At this stage EPR on n°4 engine increased rapidly. The aircraft veered to the left of the centerline at about 7400 feet from the approach end of runway 25R and departed the runway edge at 8000 feet from the approach end of runway 25R with 2,500 feet of runway remaining. Shortly before the aircraft departed the runway, the pilot flying (copilot) reported that he had no brakes and no nose wheel steering. The captain stated that he got on the brakes and tiller at this time to assist. After departing the runway surface the aircraft travelled 380 feet through soft mud before it came to rest at a point about 2100 feet from the end of runway 25R, heading about 160 degrees on the Southern side of the runway with the tail of the aircraft 120 feet from the runway edge. Shortly after the aircraft departed the runway, the nose gear struck a VASI light installation and its concrete base causing the nose gear to collapse backwards and to the left, resulting in total destruction of the VASI light installation and damage to the forward cargo hold, floor of the first class section and the stairway leading to the upper deck. Damage to the aircraft was substantial and it was not repaired. All 243 occupants evacuated safely.

At an excessive approach speed, the crew landed too far down on a wet runway due to rain. After touchdown, the crew applied full brake and deployed the drag chute but this caused all wheels to block and all tire to burst. Unable to stop within the remaining distance, the airplane overran, lost its left main gear and part of its left wing before coming to rest. All 93 occupants were evacuated, among them 12 were injured. The aircraft was damaged beyond repair. The airport just reopened to traffic following the ground fire of an Air France Boeing 747 on June 12.

The aircraft had landed at Palam at 1902 hours following an uneventful flight from Karachi. A thorough service check was carried out, and it was refuelled and loaded for the return flight to Karachi. The total take-off weight indicated on the load sheet was 41 589 lbs. The investigation revealed an error in the empty weight of the aircraft and the actual gross take-off weight was determined to be 41 319 lbs, which is 1 181 lbs less than the maximum permissible all-up weight. At 2018 hours the aircraft commenced its take-off run and was airborne at the latter half of the runway. Soon afterwards flames were observed at the western boundary of the airfield. The crash crew chief had watched the aircraft take-off. He saw the aircraft becoming airborne and then climbing to a height estimated by him to be 50 ft. He then noticed the landing lights pointing downwards and the aircraft losing height. He feared that a crash was imminent and immediately instructed the crew to proceed in that direction. At about this time the crash siren was sounded. The crash tender reached the site of the accident in about 7 to 8 minutes by which time the fire had reached large proportions. Fatal injuries were sustained by 4 members of the crew, 17 passengers and 2 others who were in the vicinity of the crash. Nine passengers and one other were seriously injured. The aircraft was destroyed by impact and fire.
