On May 6, 2018, about 1510 eastern daylight time, an experimental, amateur-built Apollo AG-1 gyroplane, N141C, was substantially damaged when it collided with power lines during a precautionary landing near Smith Beach, Virginia. The private pilot sustained minor injuries. The gyroplane was operated by the private pilot as personal flight conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Instrument meteorological conditions prevailed and no flight plan was filed for the flight that departed Halifax-Northampton Regional Airport (IXA), Roanoke Rapids, North Carolina, about 1330. The flight was destined to Accomack County Airport (MFV), Melfa, Virginia.The pilot reported that he started to fly across the Chesapeake Bay to the Cape Charles VOR at 1,300 ft above ground level. As the airplane approached the shoreline at the Cape Charles VOR, the pilot turned north toward MFV. At that time, the cloud ceiling began to lower very rapidly, so he made the decision to land at a private airstrip prior to MFV. He mistook a road for the private airstrip and the gyroplane collided with power lines during the attempted landing. The pilot added that there were no preimpact mechanical malfunctions with the gyroplane. Examination of the wreckage by a Federal Aviation Administration inspector revealed that it was intact and resting on its right side on a road. The inspector noted that the fuselage sustained substantial damage. He did not observe any anomalies with the flight controls and was able to successfully test-run the engine on the airframe. The recorded weather at MVF, at 1515, was: wind from 170° at 4 knots; visibility 1 3/4 miles in mist; overcast ceiling at 500 ft; temperature 18° C; dew point 17° C; altimeter 29.85 inches of mercury. The pilot also reported that he utilized weather equipment onboard his gyroplane, but did not receive a weather briefing from flight service.
