Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that while on short final he slowed the airplane down and “flared too soon over the runway which caused a hard landing.” Subsequently, the main landing gear collapsed on the grass runway and the airplane skidded to a stop upright. The fuselage sustained substantial damage. Photographs of the accident site revealed that a small bird house attached to a metal pole was struck by the tail of the airplane. The pole was about 5 ft tall co-located with a white fence and was located about 35-40 ft prior to a yellow tire that marked the location of the grass runway’s threshold. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
