Accident & incident history

1998-12-23 Accident · Quincy, CA Damage: Destroyed Fatal injury NTSB · LAX99FA057
Reported aircraft: Bell UH-1H — a different aircraft that carried the N4590 registration before this airframe.
Probable cause: An inaccurate exhaust gas temperature gauge, that allowed the engine to be run over-temperature unknowingly by the pilot, which resulted in the subsequent failure of the turbine sections. Also causal was the pilot's failure to maintain rotor RPM during the autorotation. A factor in the accident was the operator's failure to adequately perform engine health indicator tests.
