Cessna 182RG Gear-Up Landing Due to Pilot Oversight and Inoperative Warning System (N1818R)

What happened

The pilot reported that he intended to complete one circuit around the airport traffic pattern to warm the engine oil prior to an annual inspection of his Cessna 182RG. During this maneuver, he failed to extend the main landing gear before attempting to land. The aircraft touched down on its belly, resulting in the main landing gear bulkheads being minimally ground down during the slide across the concrete runway surface.

The investigation

A postcrash examination of the aircraft revealed that the electrical warning module associated with the landing gear warning system was inoperative. This mechanical failure meant that the pilot did not receive an audible or visual alert indicating that the gear was not fully locked down during the approach and landing phase.

Findings

The primary factor contributing to this incident was the pilot's failure to extend the landing gear. This oversight occurred despite the presence of a warning system, which was found to be non-functional. The combination of human error and equipment failure resulted in the gear-up landing condition.
