Southwest Air Lines Flight 611


Southwest Air Lines Flight 611 is the only significant aircraft accident on record at Ishigaki Airport. The accident occurred on 26 August 1982 when the Boeing 737-200 overran the runway while attempting to land. The aircraft caught fire and was destroyed, but none of the 133 passengers and 5 crew died in the accident although two crew and one passenger were seriously injured.

Flight

Southwest Air Lines Flight 611 took off on runway 36 from Naha Airport on the island of Okinawa at 13:09 for a regular flight to Ishigaki Airport, Japan. The aircraft climbed to the cruising altitude of Flight level 240. On approach to Ishigaki, the crew was given weather information for Ishigaki — wind 300 degrees at 12 knots; temperature 32 degrees C ; active runway: Runway 22. The crew of Flight 611 made a crosswind landing at a speed slightly higher than the reference airspeed. The aircraft bounced and on touching down again the spoilers and thrust reversers did not seem to operate. The flight crew shut down both engines but this action disabled the anti-skid braking system, and during the landing rolls the inner tires on both main gear legs burst almost simultaneously. Flight 611 overran the runway and came to rest 145 meters beyond the threshold at 13:49. Everyone on board was evacuated. At 14:01 the Boeing 737 caught fire and was destroyed.
None of the 138 passengers and crew were killed in the accident, but 67 were injured. Serious injuries were prevented by a quick evacuation although a stewardess and an elderly woman passenger were detained in hospital.
