While approaching a private airstrip, a pilot reduced engine power to idle and applied carburetor heat during a 3-to-5-minute glide. When additional power was needed, the engine did not respond, leading to a forced landing into transmission wires and terrain.

Incident Overview

A pilot reported that while approaching a private airstrip for landing, he reduced the engine power to idle, pulled on the carburetor heat, and glided for 3 to 5 minutes. During this glide, he never cleared the engine. He later realized that the approach would be short and that additional power would be required to reach the airstrip. When he moved the throttle forward, there was no increase in power response.

Forced Landing

The pilot stated that the airplane was very low to the ground, leaving insufficient room to maneuver. During the subsequent forced landing, the airplane impacted transmission wires and then the ground.

Environmental Conditions

The temperature and dew point were 75 degrees Fahrenheit and 53 degrees Fahrenheit, respectively. According to icing probability charts, conditions were favorable for carburetor ice formation.

Pilot Actions

The pilot reported that he reduced the engine to idle, applied carburetor heat, and did not clear the engine during the prolonged glide. No further details regarding the aircraft or injuries were provided in the source.
