Incident Overview
A pilot reported a hard landing after encountering difficulties during the final approach. According to the pilot's statement, the Visual Approach Slope Indicator (VASI) indicated that the airplane was high when turning onto the final approach leg. The pilot subsequently reduced speed and reacquired the VASI.
Sequence of Events
Approximately 100 feet from the landing threshold, the pilot extended the flaps to the full down position. At that point, the airspeed was 60 knots, and the airplane was about 30 feet above the runway threshold with a high sink rate. The pilot initiated a roundout, but the flare was executed late. As a result, the airplane collided with the runway, bounced about 6 feet into the air, pitched up, and yawed to the left. The pilot added power, but the airplane then struck the runway hard, bounced again, and impacted the runway in a nose-down attitude on the nose gear and left main landing gear.
Post-Event Examination
After the airplane was shut down, an examination revealed that the firewall was buckled. No other damage items were noted in the report.
