Incident Overview
On a scheduled service (flight NU611) from Naha Airport to Ishigaki Island, the aircraft departed Naha at 1309 LT with 133 passengers and a crew of five. The flight to Ishigaki was uneventful at an altitude of 24,000 feet. The crew received clearance to descend to 8,000 feet and then to 3,000 feet on approach.
Approach and Landing
Ishigaki Airport was using Runway 22. The wind was from 300° at 12 knots, and the outside air temperature was 32°C. The aircraft landed with crosswinds at a speed 6 knots above Vref. The landing involved a bounce, followed by a second touchdown.
Post-Landing Events
After touchdown, the spoilers and thrust reversers appeared to be inoperative. The crew decided to shut down both engines, which rendered the anti-skid system unusable. The inner tires on both main landing gear burst almost simultaneously when the aircraft was 125 meters from the runway end. The airplane skidded to the left, overran the runway, and came to rest 145 meters beyond the runway end.
Evacuation and Fire
All 138 occupants evacuated quickly. Among them, 49 were injured. Twelve minutes after the aircraft came to rest, one of the engines exploded and caught fire. The aircraft was partially destroyed by the subsequent fire.
Damage
The aircraft sustained partial destruction due to fire.
