The noncertificated pilot in an unregistered light sport airplane, reported that he departed the runway during the initial takeoff climb and could not gain altitude. He attempted to return to the runway and landed hard in an orchard. The pilot later reported that prior to takeoff, a large helicopter was hovering close to the runway. "I believe I entered his rotor wash and lost lift."

The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The airplane sustained substantial damage to the wings.

The uncertificated pilot did not submit the NTSB Form 6120.1 Pilot/Operator Aircraft Accident/Incident Report.
