SYNOPSIS
On Thursday, May 5, 2016, at around 11:56 Japan Standard Time (JST: UTC + 9 hours a privately owned Glasflügel 304CZ-17, registered JA21BB (glider, single seater), took off from the Kakuda Glider Field in Kakuda City, Miyagi
Prefecture by aero tow for a training flight, but crashed in a mountain forest in Miharu Town, Tamura-Gun, Fukushima Prefecture at around 14:05.
The pilot was the only person on board the aircraft, and he was fatally injured. The glider was destroyed.
Probable Causes:
- It is highly probable that this accident occurred when JA21BB crashed in a mountain forest because it broke up in mid-air while flying.
- It is somewhat likely that the glider broke up in mid-air because, after it had entered a steep turn and stalled while the pilot had succumbed to a state of hypoxia and was semi-conscious, excessive bending occurred owing to aerodynamic force on the glider and the glider was subjected to load exceeding the ultimate maneuvering load, influenced by the fact that the glider assumed a significant nose-down attitude including spin and nosedived, and that it passed through an area of turbulence.
