Narrative:JAL Flight 350 took off from Fukuoka (FUK) runway 16 at 07:34 for a regular flight to Tokyo-Haneda (HND). The aircraft climbed to the cruising altitude of FL290. At 08:22 the crew started their descend to FL160. After reaching that altitude, they were cleared to descend down to 3000 feet. The aircraft was cleared for a runway 33R ILS approach and 5deg of flaps were selected at 08:35, followed by 25 degrees of flaps one minute later. The landing gear was lowered at 08:39 and 50 degrees of flaps were selected two minutes after that. At 08:42 the aircraft descended through 1000 feet at an airspeed of 135 knots with wind from a direction of 360deg at 20 knots. The co-pilot called out "500 feet" at 08:43:25 but the captain did not make the "stabilized" call-out as specified by JAL operational regulations. The airspeed decreased to 133 knots as the aircraft descended through 300 feet at 08:43:50 and the co-pilot warned the captain that the aircraft was approaching the decision height. At 08:43:56 the radio altimeter warning sounded, followed by the flight engineer calling out "200 feet", which was the decision height, three seconds later . At 08:44:01 the aircraft descended through 164 feet at 130KIAS. At that moment the captain cancelled autopilot, pushed his controls forward and retarded the throttles to idle. The co-pilot tried to regain control but the aircraft crashed into the shallow water of Tokyo Bay, 510m short of the runway 33R threshold. The nose and the right hand wing separated from the fuselage. The captain had recently suffered a psychosomatic disorder; preliminary reports suggested that the captain experienced some form of a mental aberration. He had been off duty from November 1980 to November 1981 for these reasons.
