Incident Overview
A Cessna 172RG aircraft made a landing with its landing gear retracted. After touching down, the aircraft slid off the runway and struck a snowbank.
Pilot Actions
The pilot reported that a warning horn sounded after takeoff, prompting a return to land. On the initial approach, the pilot lowered the landing gear but then raised it after sighting another aircraft in the traffic pattern. On a second approach, the pilot did not lower the landing gear.
Subsequent Inspection
Following the incident, an inspection of the aircraft found no malfunction with either the stall warning horn or the landing gear warning horn. However, a witness reported hearing the landing gear warning horn in the background when the pilot transmitted on the radio.
