Incident Overview
A flight instructor reported that during a landing attempt, the student pilot was controlling the aircraft. The airplane floated down the runway and eventually touched down on the first third of the runway. After the initial touchdown, the airplane bounced. During the second bounce, the instructor announced that he was assuming control of the aircraft and simultaneously advanced the throttle to full power.
Throttle Restriction and Maneuver
However, the student pilot's hand position on the throttle prevented the instructor from achieving full throttle application. The instructor was attempting to gain altitude without stalling the airplane. Due to the restricted throttle, the airplane subsequently struck a fence near the departure end of the runway.
Forced Landing and Damage
After striking the fence, the instructor reduced power and initiated a forced landing to an open field. The airplane sustained substantial damage to the left side horizontal stabilizer. The instructor reported that there were no mechanical malfunctions or failures that would have precluded normal operation.
