## Analysis

ACCORDING TO THE PLT, THE ACFT WAS STANDING UNATTENDED WITH THE ENG RUNNING AT 1000 RPM WHEN AN INEXPERIENCED PERSON ATTEMPTED TO SHUT DOWN THE ENG. HE REPORTEDLY PUSHED THE THROTTLE IN, INSTEAD OF PULLING IT OUT & THE ACFT JUMPED THE CHOCKS. ACCORDING TO 2 OTHER INDIVIDUALS, THE PLT INITIATED A TAKEOFF, BUT HE SAID THE ENG DID NOT DEVELOPE SUFFICIENT POWER, SO HE MADE A FORCED LANDING. SUBSEQUENTLY, THE ACFT HIT TREES & WAS DAMAGED. THE PLT HAD NO RECENT FLYING TIME.
