Incident Overview
A certificated flight instructor (CFI) and a student pilot were practicing crosswind takeoffs and landings in a Cessna 172S. The wind was 8 knots from a 90-degree angle relative to the runway. During the second landing attempt, as the airplane crossed the runway threshold, the student reduced engine power more abruptly than on the previous landing. The airplane bounced, and the flight instructor instructed the student to add power.
Sequence of Events
After the first bounce, the student removed the wind correction on the ailerons and tensed up. The flight instructor attempted to re-apply left aileron control and told the student, "don't fight me." The student then added power while the flight instructor retracted the flaps from the 10-degree setting. The flight instructor expected the student to increase engine power to full for a go-around, but the student did not, and the airplane bounced a second time.
Runway Excursion and Damage
The airplane was at the far right edge of the runway when the flight instructor assumed control and reduced engine power to idle. The aircraft continued off the right side of the runway onto a grass area, where it struck an embankment and nosed over. The accident resulted in substantial damage to the fuselage, wing spar, and firewall.
Flight Crew
The flight instructor and student pilot were the only occupants. No injuries were reported in the source.
