## Analysis

THE ACFT DRIFTED LEFT OFF THE RWY DURING TAKEOFF AND COLLIDED WITH TREES. THIS WAS A HOME BUILT ACFT THAT HAD JUST BEEN CERTIFIED. THE OWNER/BUILDER HAD MADE HIGH SPEED TAXI RUNS BUT DID NOT FEEL COMFORTABLE TO FLY IT. ANOTHER PLT WAS ASKED AND AFTER A SHORT TAXI AND RUN-UP THIS PLT ATTEMPTED TO FLY. HE LOST CONTRL AND CRASHED AFTER COLLIDING WITH THE TREE LINE TO THE LEFT OF THE RWY. THE OWNER/BUILDER SAID THAT THE POWER WAS APPLIED TOO RAPIDLY WITH TOO LITTLE RIGHT RUDDER APPLIED INITIALLY. BY THE TIME FULL RT RUDDER WAS APPLIED THE ACFT WAS GOING LEFT OFF THE RWY AND WAS PULLED OFF THE GROUND PREMATURELY TO TRY TO GET OVER THE TREE LINE. THIS WAS THE ACFTS MAIDEN FLT.
