Recent Agustawestland Philadelphia AW139 accidents
The inflight loss of collective control of the helicopter due to thermal damage of a collective control torque tube that abraded with misrouted electrical wiring, which resulted in an electrical short and inflight fire. Contributing to the accident were the incorrectly manufactured wiring support strip assembly that misrouted electrical wires near the collective control torque tube, the ambiguity of the support strip assembly drawing that allowed for its incorrect manufacturing, the inadequate quality control processes to identify the incorrectly manufactured support strip assembly, and the helicopter manufacturer’s inadequate assembly instructions that allowed the misrouting of the electrical wiring, due to the incorrectly manufactured strip assembly, on the helicopter production line.
A yaw excursion and uncontrolled descent due to loss of tail rotor effectiveness during aerial firefighting operations resulting in an impact with trees. A contributing factor was the pilot’s failure to maintain sufficient airspeed, coupled with a quartering tailwind during aerial firefighting operations. An additional factor was the operator’s lack of guidance to the hazards associated with aerial firefighting operations near and around smoke columns.
The fatigue failure of a tail rotor blade erosion shield extension, which resulted in in-flight damage to a main rotor blade.
