Incident Overview
A training flight at the Frisco Jetport ended with a hard landing that caused substantial damage to the aircraft. The flight instructor stated the purpose was to practice maneuvers and landings to prepare the student for a commercial pilot flight evaluation.
Sequence of Events
According to the instructor, the pattern to runway 17 was normal. Upon crossing the threshold between 50 and 75 feet above ground level (AGL), the student closed the throttle and slightly lowered the nose to maintain airspeed. At 15 feet AGL, the student raised the nose to initiate the round out. When this did not slow the rate of descent, both the instructor and student reached to apply power. The aircraft then landed "particularly hard," bounced, and became airborne again.
The instructor recognized that the left main landing gear had been "ripped off" and took control, landing on the right main gear. The aircraft came to rest with its nose off the edge of the runway in an upright position.
Damage
The aircraft sustained damage to the main landing gear, the left landing gear, the propeller, and the left wing.
Conditions
The recorded winds at the Addison Airport, located 10 nautical miles south of the Frisco Jetport, were from 180 degrees at 18 knots. The density altitude, calculated by the NTSB investigator-in-charge, was 2,247 feet.
