What happened
On February 15, 2009, a training flight involving a Wills Wing Falcon 3 hang glider ended in a fatal accident near Jämsänkoski, Finland. The flight was a significant milestone for the trainee pilot, intended to be their first high-altitude solo flight. The glider was being operated via a car-towed method.
Following a normal takeoff, the glider began to veer to the right. Approximately 250 meters from the launch site, the aircraft underwent a sharp rightward turn and plummeted from an altitude of roughly 50 meters onto the ice of a frozen lake. The trainee pilot sustained fatal injuries and died instantly at the scene.
The investigation
The investigation established that the glider had deviated significantly from the established tow line prior to the loss of control. While the aircraft itself was suitable for training, it had not been officially registered in the Finnish Aeronautical Association's glider catalog.
Investigators also examined the training environment and found that the instructional methods used did not fully comply with the training program approved by the Civil Aviation Authority. Furthermore, a previous safety inspection of the training club by the Finnish Aeronautical Association had failed to identify these instructional deficiencies. The investigation also noted the absence of a line-cutting knife and the fact that the tow release mechanism was located at a distance that could have complicated emergency procedures.
Findings
- The primary cause of the accident was the glider deviating from the tow line, which led to a subsequent loss of control.
- Contributing factors included insufficient training regarding towing procedures and the use of an unapproved training curriculum.
- Inadequate quality control of hang gliding training activities was identified as a systemic issue.
- The change of instructor immediately prior to the flight may have hindered the ability to identify potentially diminished pilot performance.
- Environmental factors, such as the difficulty of maintaining precise directional orientation over a uniform white snow surface, may have contributed to the deviation.
