Re: F-15 Fighter Jet Crash

On June 11, 2018, approximately at 6:26 AM, a U.S Air Force F-15 fighter jet crashed in the waters south of Okinawa

Although no damage to the Okinawa residents from the accident has been reported, one misstep of aircraft-related accidents could result in a serious accident involving human lives and property.

The U.S Forces aircrafts including those belonging to Kadena Air Base, caused as many as 30 accidents including a forced landing into flames, fallen parts and emergency landings within only the past one year. Every time such accidents took place, we, the Okinawa Prefectural Government, and concerned municipalities requested the U.S. Forces to conduct thorough examination of aircraft maintenance system. We cannot contain our strong indignation that the accident took place despite our repeated requests.

Furthermore, we were informed that the U.S Air Force has implemented the operational safety review of all aircrafts in the wake of a series of serious accidents and the review of all air force units belonging to Kadena Air Base was completed by May 21st this year. However, the accident took place after the review and thus, it has raised serious doubts and distrust concerning the aircraft maintenance and the safety measures put in place by the U.S. Forces.

We strongly protest against the occurrence of the accident and demand fundamental review of aircraft maintenance and safety management system. We also firmly call for suspension of the flight of the aircrafts in question until the cause of the crash is determined, as well as a thorough investigation into the cause, prompt disclosure of the findings, and implementation of effective preventive measures.

Takeshi Onaga
Governor
Okinawa Prefectural Government
