Incident Overview
A pilot reported that the departure airport was situated in a valley surrounded by mountains, with an elevation of approximately 6,800 feet. With the wind from the northwest, Runway 33 was determined to be the most favorable for takeoff. A ridge located about half a mile north of the airport necessitated a turn to the east after departure, followed by flying out of the valley along a road. The temperature at the time was estimated to be 70 degrees Fahrenheit.
Fuel and Departure
The aircraft was refueled to the minimum fuel load required for the trip. The pilot stated that after takeoff, he turned to the east as planned. Shortly thereafter, the aircraft encountered downdrafts and turbulence, and the pilot was unable to maintain or increase altitude.
Power Line Strike and Landing
During the encounter with the downdrafts, the aircraft struck power lines. Despite the impact, the aircraft remained airborne and continued flying. The pilot was able to land the aircraft without further incident.
