Probable cause

The premature liftoff by the PIC and his failure to attain proper rate of climb. Factors relating to the accident were the gusty crosswind weather conditions, the failure of the PIC to use all available runway, and transmission wires.

Analysis

The PIC initiated a takeoff from a runway intersection, lifted off prematurely, and the acft settled back onto the runway. The PIC continued the takeoff and lifted off at the end of the runway. The acft settled slightly after takeoff and began a shallow climb. When the acft approached power lines at an altitude too low to clear the wires, the pilot attempted to turn to avoid impact. The left wing struck power lines located about 2500 ft from the end of the runway, and the acft descended uncontrolled and impacted the ground.
