Japan Ground Self-Defence Force’s (JGSDF) OH-1 Ninja light observation helicopter fleet resumed on March 1, 2019, after a gap of nearly four years.
The helicopter fleet was grounded following a crash in February 2015. The crash was attributed to faulty engine parts, according to Scramble Magazine.
The OH-1 is manufactured by Kawasaki Heavy Industries for the JGSDF. The helicopter is a successor to the OH-6D helicopter of the JGSDF.
