Saudi Arabian Airlines / Kazakhstan Airlines Flight 763/1907Tuesday November 12, 1996
Midair collision 17 km W of New Delhi. The Saudi 747 had just taken off from New Delhi airport ascending to 14,000 feet while the Il-76 was descending. Three hundred twelve aboard the B-747 and thirty-seven aboard the Il-76 were killed. The Il-76 descended below its assigned altitude. The death toll was reduced from 351 to 349 after Kazakstan Airlines reported 37 aboard rather than 39. Neither aircraft was equipped with an Airborne Collision Avoidance System. The 747 had taken off from Delhi and had been cleared to climb to FL140. Meanwhile, the IL76, which was inbound to Delhi on the same airway, had been cleared to descend to FL150. However, due to a misunderstanding, the pilot and most of the cockpit crew of the IL76 believed the flight had been cleared to continue down to FL140. The Indian accident report attributed the failure of most of the IL76 crew to correctly understand the situation due to their lack of a working knowledge of English. Also contributing to the crew's decision to continue the descent below their clearance limit were poor cockpit resource management, a lack of leadership by the captain, a lack of co-ordination between the crew and a general casual attitude to the conduct of the flight.
