NTSB narrative
The pilot reported that, in anticipation of a difficult approach and landing due to the reported wind, he configured the airplane early with the mixture rich, propeller at high rpm, and the fuel selected to the fullest tank. He did not extend the landing gear due to the distance from the airport. The pilot entered the traffic pattern on a normal 45-degree entry for landing. On final approach, he failed to perform the prelanding checklist and to confirm that the landing gear was down. The airplane touched down on the runway with the landing gear retracted, which resulted in substantial damage to the fuselage structure. The pilot stated that, during the annual inspection, the gear warning horn system was noted to be out of adjustment, and this had not been resolved. The pilot reported no other preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot’s failure to extend the landing gear before landing. Contributing to the accident was an uncorrected malfunction of the landing gear warning horn system.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2012-07-12.
