Probable cause
Impact with power lines due to the pilot’s obscured vision due to the low angle of the sun, which prevented the pilot from seeing the lines.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
According to the pilot of the gyroplane, he was practicing aborted takeoffs from a field that had power lines near the practice area and performing 180-degree turns to simulate a return to the runway. He successfully completed one practice maneuver, taking off to the south and making a 180-degree turn to the north. During the second practice maneuver, he took off to the north and began a 180-degree turn to the south. The pilot stated that, immediately after making the turn, the sun obscured his vision for several seconds. The gyroplane then struck a power line, and the pilot pushed the cyclic forward to land in the field. Subsequently, the gyroplane impacted the ground hard, which resulted in substantial damage to the airframe. At the time of the accident, the angle of the sun was low and directly in the flightpath during the turn. The pilot reported no preimpact mechanical malfunctions or failures with the gyroplane that would have precluded normal operation.
Factual narrative
According to the pilot of the gyrocopter, he was practicing aborted takeoffs with 180-degree turns to a simulated runway in a field that had power lines in the vicinity of the practice area. He successfully completed one simulated aborted takeoff and turned back toward the simulated runway. During the second practice maneuver, he took off to the north, and began the 180-degree turn to the south. The pilot stated the sun obscured his vision for several seconds, the gyrocopter struck a powerline, and he pushed the cyclic forward in order to land in the field. Then, the gyrocopter impacted the ground hard, which resulted in substantial damage to the airframe. The pilot reported no preimpact mechanical malfunctions or failures with the gyrocopter that would have precluded normal operation.
