What happened
During the final approach phase of a training flight, the student pilot realized the aircraft was too high. In an attempt to descend, the student reduced power to idle and deployed full flaps while on short final.
The instructor observed that the airspeed had dropped to between 80 and 85 mph and the descent rate had increased to approximately 1,000 feet per minute. While the instructor expected the student to add power to arrest this descent, the student instead initiated an early roundout.
Upon noticing the situation, the instructor took control of the aircraft and advanced the throttles. Despite this intervention, the airplane abruptly veered to the right. The aircraft subsequently made a hard landing approximately 1,000 feet past the runway threshold, coming to rest about 100 feet to the right of the runway. There were no injuries reported.
