Incident Details
The pilot reported that during the base leg of the approach, he was engaged in multiple communications on both company frequency and UNICOM while adjusting the traffic pattern to accommodate slower traffic on the runway and maintaining aircraft control in gusty wind conditions. He stated that the landing gear handle was selected to the down position and verified on the checklist review, but he did not check the gear down panel lights due to line-of-sight interference caused by the right side control yoke and distractions from communications and traffic.
Landing and Aftermath
As the pilot reduced power for the flare, the landing warning horn did not sound. The horn is connected to a relay that is linked to the gear handle. The aircraft subsequently landed with the landing gear retracted, resulting in a wheels-up landing.
Post-Inspection Findings
An inspection of the landing gear system revealed that the gear had partially extended, but the extension motor had failed. The failure prevented the gear from completing its extension cycle.
Probable Cause
No probable cause was stated in the source.
