Maintenance Misdiagnosis Precursor to Tail Rotor Control Failure
On 9 December 2007 Eurocopter EC135T2 JA31NH, operated by All Nippon Helicopter, took off from Tokyo Heliport for a ferry flight to Shizuoka Heliport. The helicopter crashed on approach after a loss of tail rotor (fenestron) control. The pilot died and a mechanic onboard was seriously injured.
