| Nature: | Private |

| Investigating agency: | NTSB |
| Confidence Rating: |  Accident investigation report completed and information captured |
The private pilot stated that, during landing, he pitched the airplane’s nose up "slightly" and reduced engine power before the main landing gear wheels touched down on the runway. The nosewheel landing gear then touched down and collapsed.
Postaccident examination of the nosewheel landing gear revealed that the trunnion casting was fractured. Metallurgical examination of the trunnion casting revealed fractures consistent with overstress. No evidence of preexisting cracks was observed on any of the fracture surfaces. No other mechanical malfunctions or failures that would have precluded normal operation were noted. Therefore, it is likely that the pilot did not properly flare the airplane, which led to a hard landing and the subsequent collapse of the nosewheel landing gear.
Probable Cause: The pilot’s improper landing flare, which led to a hard landing and the subsequent collapse of the nosewheel landing gear due to the overstress failure of the nosewheel landing gear trunnion casting.
