Analysis

Pilot and pax departing 2170 ft rwy at near max gross weight pax stated it didnt appear as if they were going to clear high tension power lines located about 2400 ft from rwy end. Pilot made left turn and impacted unmarked wires about 600 ft left of extended centerline. It was within the a/c performance capabilities to clear the wire obstructions of the rwy end,however,the loss of lift in the premature left turn resulted in a degredation of a/c performance. The pilot was notable to clear the additional wires during the turn.
