What happened
During an aerial application mission involving the spraying of dimilin to control gypsy moth populations, a Douglas DC-3 struck power lines while operating over hilly, wooded terrain. An observer in a nearby aircraft noted that the DC-3 began a gradual climb that eventually transitioned into a steep, nose-high attitude. Despite attempts by the observer to establish radio communication with the crew, no contact was established.
According to reports from the observation aircraft, the DC-3 entered a stall and subsequent spin at an altitude of approximately 1,200 feet above ground level before impacting the terrain. The accident resulted in two fatalities, as both pilots on board were killed.
Findings
An investigation into the accident found no evidence of mechanical failure occurring prior to the impact. It was noted that the aircraft was not outfitted with a wire cutter kit, which may have been relevant during the encounter with the power lines. The primary factor in the loss of control was the collision with power lines during the flight.
