Korean Air Boeing 777 arrived at Narita Airport from Incheon (Incheon) in June last year while traveling on the taxiway, there was a problem that the axle of the right tire near the center of the fuselage broke and could not move. The safety committee was investigating the cause as a serious incident that could lead to an accident.

According to a report published by the Japan Transport Safety Board, the aircraft seemed to continue to operate with cracks in the axle components that were corroded and broken, and the axle was broken when it landed.

This aircraft was inspected and maintained every 10 years, but no corrosion inhibitor was used when assembling the axle parts according to the manufacturer's manual at that time.

Although this manual has already been reviewed, it has been confirmed that corrosion has been confirmed even on the axles of other aircraft of the same type, and the Transport Safety Board believes that the use of corrosion inhibitors did not lead to trouble. I conclude.
