Cathay Pacific Airways flight 508 made a hard landing on runway 16 of New Tokyo International Airport, in which the rear spar of the wing root and its vicinity of the left wing were damaged and the fuel flowed out from No. 1 fuel tank. Fire did not occur. On board the aircraft were a crew of 18 and 283 passengers, and in the emergency evacuation effected, two passengers were seriously injured. Probable cause It is estimated that immediately after the aircraft, which was approaching in a crosswind varying extensively in direction and speed, initiated a decrab operation, the aircraft encountered such a change of the wind that the strong wind which had been blowing crosswise at a right angle until immediately therebefore suddenly decreased and temporarily turned to a tailwind, wherein the captain could not conduct a relevant landing operation with a result of giving rise to a hard landing.
