Incident Summary
A training flight operated by an unidentified aircraft type concluded with a runway overrun at Bilbao-Sondica Airport. The aircraft, carrying a crew of four, was completing local training maneuvers involving multiple touch-and-go landings. During a subsequent approach, the crew encountered a flaps asymmetry warning, prompting the captain to decide to continue and conduct a flapless landing.
Sequence of Events
The approach was conducted under heavy rain and with a tailwind component. The aircraft touched down further along the runway than intended, on a wet surface. After touchdown, the airplane was unable to decelerate sufficiently to stop within the remaining runway distance and overran the end. Upon leaving the paved surface and contacting soft ground, the nose landing gear and right main landing gear collapsed. The aircraft then came to rest after breaking into three sections. The crew of four evacuated without injury. The aircraft itself was destroyed.
Probable Cause
The official investigation attributed the accident to a wrong approach configuration. Specifically, the crew decided to land in a flapless configuration with a tailwind component at an excessive speed, causing the aircraft to land too far down the runway. Under those conditions, the airplane could not stop within the remaining distance.
