F35 fighter plane crash Abrupt descent due to pilot “spatial incongruity” 17:10 on August 9
About the accident that the state-of-the-art F35 fighter crashed off the coast of Aomori Prefecture, the Air Self-Defense Force was in a state of "spatial incompatibility" where the pilot could not recognize the attitude of the aircraft correctly, and there was a high possibility that it crashed without noticing the sudden drop Summarized the survey results.
In April, the Air Self-Defense Force accident investigation committee compiled an investigation report on the accident where one of the pilots died when the Air Self-Defense Force's state-of-the-art Stealth Fighter F35A1 crashed off Aomori Prefecture.
According to it, from the record left on the same aircraft that was trained together, the accident aircraft suddenly descended from an altitude of about 10000 meters and crashed in about 30 seconds, just before the crash to over 1100 km / h It seems that it was reached.
The accident aircraft began to descend to take a distance from the U.S. military aircraft that passed through the same airspace, but on the way, it seems that the pilot fell into a state of `` spatial incompatibility '' where the attitude of the aircraft could not be recognized correctly and suddenly descended about it.
The reason for the lack of spatial awareness was that the flight seemed to be affected at night, and the pilot seemed to have crashed without noticing the sudden drop.
In addition, on the accident aircraft, it seems that the warning sound that warned of the danger of the crash was sounded twice, and the pilot was not able to recover from the sudden descent, or it seems that it was not in time.
On the other hand, it is estimated that the Air Self-Defense Force had no aircraft defects, and the flight resumed from the 1st of this month.
