Safety record

Accident & incident history

2022-02-09 Accident · Bel Air, MD Damage: Substantial NTSB · ERA22LA117
Reported aircraft: Hughes 369D
Probable cause: A loss of engine power due to bearing failures in the turbine section resulting from a fatigue fracture of the oil supply line that fed oil to the Nos. 6 and 7 bearings. The oil line failure led to rapid deterioration of the bearings from oil starvation. Contributing to the power loss was the installation of a No. 8 stationary seal with an undersized outside diameter, which resulted in a reduction of support for the turbine section rotating components and resulted in high vibration loads in the engine, which ultimately caused the oil supply line to fatigue and fail. Also contributing was the improper or inadequate inspections of the No. 8 stationary seal by maintenance personnel.
2020-04-25 Accident · Pylesville, MD Damage: Substantial NTSB · ERA20LA160
Reported aircraft: Hughes 369
Probable cause: The loss of engine power due to fuel starvation as a result of unporting of the fuel tank supply pickup while the helicopter was maneuvered to move a conductor wire. Contributing to the accident was the helicopter s inappropriate configuration for the type of operation being conducted, which impeded the pilot s ability to release the long line and perform a successful emergency landing.
