Aircraft had been flying for about an hour before the accident occurred. During takeoff, the airplane was traveling about 45 mph, the pilot pushed the stick forward to raise the tail. The airplane started to pull toward the right side of the runway, so the pilot released the right rudder he had for takeoff. The airplane was traveling about 65 mph and airplane became light on its wheels, pilot pulled slightly on the stick and the airplane became airborne. The airplane was yawing to the right thus pilot released back pressure to let the airplane accelerate. The yaw to the right progressed and the airplane started to roll right with a slight pitch up. Pilot attempted to correct the roll with left aileron and coordinated left rudder, but the airplane continued to roll right. The airplane struck the right upper wing at approximately 90 degrees of bank, rolling to the right and then flipped over the nose to an inverted position.

During the investigation inspector reyes and inspector lopez found the forward and aft support tubes that attach the right horizontal stabilizer cracked and corroded. The horizontal stabilizer was still attached to the flight control cables that connect to the elevator. One nut was stripped off the top bolt that attaches the right elevator to the horn at the empennage. Both top brace wires for the right horizontal stabilizer were broken off at the base. The right aft upper brace wire showed stress marks. There was approximately 18 gallons of 100LL fuel at time of takeoff. There was no post crash fire. Stabilizer tubes were sent to NTSB laboratory in Washington d.c. for further analysis.
