Incident Overview
A pilot reported that during a routine flight, he was concentrating on practicing a close or precise traffic pattern. While on the base leg of the pattern, he intended to extend the landing gear but inadvertently added an extra notch of flaps instead. The pilot did not visually confirm the position of the landing gear or flap levers before making the selection.
Warning Horn Malfunction
The pilot also reported that the landing gear warning horn did not sound during the sequence. The absence of the auditory alert may have contributed to the pilot's failure to recognize the incorrect configuration before touchdown.
Damage Assessment
The aircraft touched down with the wheels retracted. As a result, both propellers, the belly of the airplane, and structural formers were bent or damaged during the wheels-up landing. No further details about the extent of the damage or other involved systems were provided in the report.
Pilot Actions
The pilot acknowledged that his focus on the precision of the pattern led him to neglect cross-checking the landing gear and flap controls. He did not look at the levers before actuating them, leading to the error.
