NTSB Accident History (2)
| Date | NTSB # | Damage | Highest Injury | Probable Cause |
|---|---|---|---|---|
| Apr 24, 2020 | WPR20LA130 | Substantial | Fatal | An in-flight separation of the tail rotor gearbox from the airframe due to fatigue failure of the gearbox attachment studs, resulting in a loss of directional control and subsequent ground impact. Contributing to the accident were 1) the improper application of paint on the clamping surfaces between the tail rotor gearbox and the vertical stabilizer that led to the initiation of fatigue fractures on the gearbox attachment studs and 2) the lack of a requirement to check the torque of the gearbox attachment hardware after installation of a gearbox onto the airframe. |
| Jul 15, 2008 | LAX08LA230 | Substantial | Minor | A total loss of engine power due to the failure of the No. 1 bearing for undetermined reasons. |
