Circumstances:
The Boeing 727 departed Sapporo-Chitose Airport on a regular schedule flight to Tokyo-Haneda, carrying a crew of 7 and 155 passengers. While cruising at 28,000 feet, the airplane collided with a Japan Air-Self Defence Force North American F-86F Sabre registered 92-7932 and carrying a crew of two. Following the collision, both aircraft went out of control, dove into the ground and crashed in a mountainous area located south of Shizukuishi. While both military pilots were able to eject and were uninjured, all 162 occupants on board the 727 were killed.
Probable cause:
It was determined that the military pilot under training failed to see and avoid other traffic while conducting a training mission. Relatively inexperienced, the trainee pilot had a total of 25 flying hours and delayed a corrective manoeuvre as ordered by his instructor. This caused the right wing of the Sabre to struck the horizontal stabilizer of the B727.
