Incident Overview
During final approach for a power-off landing demonstration, the aircraft experienced a hard touchdown, resulting in substantial damage. The pilot reported that during the landing flare, he noticed his aiming point was 'moving in the wrong direction.' He immediately attempted to add power, but as he did so, the aircraft arrived at the ground and '3 pointed,' causing damage.
Runway Conditions
The pilot stated that the runway had 'a large drop from about 50 percent of the length to the north.' He further indicated that he thought 'the gradual loss of headwind when [he] descended below the crest of the runway, and the resultant loss of translational lift, allowed an increase in descent rate that went undetected until the flare.'
Pilot Actions
The pilot was demonstrating a power-off landing. He noted that his aiming point began moving in the wrong direction during the flare, prompting an immediate attempt to add power. However, the aircraft contacted the ground before the power application could arrest the descent rate, resulting in a hard three-point landing and structural damage.
Conclusion
The accident investigation source provides the pilot's description of events and runway characteristics but does not state a probable cause for the incident. The information is limited to the pilot's statements and the resulting substantial damage.
