Safety record

Accident & incident history

2024-07-26 Incident · Oktaha, OK Damage: Minor NTSB · ENG24LA028
Reported aircraft: Bell 407
Probable cause: The loss of engine power due to high cycle fatigue failure of a power turbine stage 3 turbine wheel blade. The resulting engine imbalance caused a decoupling of the gas producer stage 1 and stage 2 turbine wheels leading to a stage 1 turbine overspeed and subsequent turbine wheel burst.
