Incident Overview
During a descent from 1800 to 1500 feet above ground level (AGL), the pilot adjusted the throttle to maintain airspeed and altitude. However, the throttle became unresponsive; it could be pushed in and pulled out without any change in engine power.
Landing and Impact
The pilot executed a crosswind landing on a road that was under construction. While maneuvering to avoid debris on the road, the aircraft struck a canister, causing the left main landing gear to be sheared off.
Pilot Observations
The pilot reported that the weather was clear, with wind from the south at 10 knots, gusting to 15 knots. Approximately 20 miles away, a weather station recorded wind from 110 degrees at 10 knots and a temperature of 88 degrees Fahrenheit. The pilot speculated that the carburetor may have frozen, but this was not verified.
Aftermath
No further details about the aircraft, occupants, or subsequent actions were provided in the source.
