Hughes 369 Safety Record

The flight instructor's failure to verify that the helicopter's skid was clear of an obstruction while demonstrating a one-skid and toe-in landing maneuver. Contributing to the accident was the flight instructor's decision to practice this maneuver at an unauthorized landing site.

The loss of engine power due to fuel starvation as a result of a loose fuel filter upper drain cap, which was not properly secured by maintenance personnel.

The passenger's inadequate visual lookout and failure to maintain clearance from the rotating main rotor disc while the helicopter was hovering. An uphill terrain condition was a factor

The pilot's failure to maintain clearance from the surface of a pond that he was using as a water bucket refill site, which resulted in a tail rotor strike to the water's surface and a torsional overload failure of the tail rotor drive shaft.

The inadvertent entanglement of the crewmemeber's helmet's communication cord with the structure of the helicopter during the helicopter's ascent, which resulted in the crewmember being elevated above ground level before the helmet's cord separated, resulting in the crewmember falling into an apple tree. A factor was the pilot's diminished visual lookout.

The pilot's loss of helicopter control while maneuvering at low altitude, which resulted in a hard landing. The wind gusts were a contributing factor.

The fatigue failure of a turbine blade due to a localized over-temperature of the turbine section as result of a non-uniform fuel distribution by the fuel nozzle. Contributing to the accident was the close proximity of a power line support structure which restricted maneuverability for a successful autorotation.

A partial loss of engine power due to fatigue fracture of the power turbine governor spring, causing a false pneumatic signal to the fuel control and a corresponding reduction in fuel flow.

Fatigue cracking of the oil line from the engine gearbox to the oil pressure gauge, which resulted in loss of engine lubricating oil, leading to seizure of the power turbine.

The inadequate clearance from a tranquilized moose while hovering in ground effect, and the operator's inadequate procedures for such operations, which resulted in an in-flight collision with the moose. Factors associated with the accident were the moose, a sheared tail rotor drive shaft, and the resultant lack of tail rotor anti-torque control.

The pilot's intentional flight into adverse weather conditions, which resulted in a loss of engine power during hover due to snow and ice ingestion. Factors associated with the accident are the pilot's delayed remedial actions, and snow and icing conditions.

The pilot's failure to maintain clearance with the transmission wires due to an inadquate visual lookout while maneuvering during a search and rescue flight.

the pilot's failure to shut down the engine prior to exiting the helicopter resulting in the tail rotor contacting the ground. A contributing factor was the gusting wind conditions present at the accident site.
