Safety record

Accident & incident history

2004-04-03 Accident · Bakersfield, CA Damage: Substantial Serious injury NTSB · LAX04LA176
Reported aircraft: Bell 47G-4A
Probable cause: a loss of tail rotor drive due to a disconnection of the drive shaft's splined coupling at the tail rotor gear box. The splined coupling to tail rotor gear box disconnection occurred as a result of tail boom flexing due to the combined effects of an uninstalled structural support tube and a crack in left side frame tubes. Inadequate maintenance inspection was a factor.
