Last month's KF-16C crash attributable to maintenance error: Air Force
2022/12/30
SEOUL, Dec. 30 (Yonhap) -- The South Korean Air Force on Friday attributed last month's crash of a KF-16C fighter jet to a maintenance error that led to the abrasion of a fuel pump part and an engine stoppage.
Wrapping up a month-long investigation, the armed service said that the crash on Nov. 20 was ascribed to a failure by maintenance staff to lock a nut -- used to fixate the drive shaft of the engine fuel pump -- during maintenance work in 2010.
The absence of the nut caused the abrasion of a cogwheel on the drive shaft, which blocked the normal transfer of fuel to the engine.
