The pilot and passenger were conducting a local flight in a powered parachute from a grass field. The pilot elected to take off to the north-northwest to take advantage of the light wind from that direction instead of taking off to the northeast with a light crosswind. The pilot was aware of trees and powerlines on the departure route to the northwest but thought he could turn left after takeoff to avoid the obstructions. The powered parachute did not climb as quickly as usual during the left turn so the pilot turned back to the right thinking he could parallel the power lines. The powered parachute did not turn as quickly as expected and continued to climb toward the power lines. The pilot thought he had cleared the power lines, but the parachute impacted the static wire above the power lines, which collapsed the parachute, and the airframe fell to the ground. The airframe sustained substantial damage. The pilot reported that there were no mechanical anomalies with the powered parachute that contributed to the accident and said he should have taken off to the northeast and accepted the light crosswind.
