Kettle River, MN, US

On May 16, 1994, a Stinson 108-2 (registration N9761K) operated by Steven J. Korhonen was involved in an aviation accident near Kettle River, MN. Investigators recorded the probable cause as: THE PILOT'S IMPROPER USE OF CARBURETOR HEAT AND THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING. THE CARBURETOR ICING WEATHER CONDITION WAS A FACTOR. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot reported engine power loss seconds after takeoff, leading to a forced landing into trees. Investigators found no mechanical anomaly but noted carburetor icing conditions.

Accident Overview

A pilot experienced a loss of engine power shortly after takeoff, resulting in a forced landing that brought the aircraft into contact with trees. The pilot reported that the engine lost RPM, sputtered, and stopped approximately 10 to 12 seconds after departure.

Pilot Report

According to the pilot, the engine progressively lost revolutions per minute, began sputtering, and ultimately ceased operation. The pilot executed a forced landing, but the airplane struck trees during the descent. The pilot also stated that a carburetor heat check had been performed during the pre-takeoff run-up.

Investigation

FAA inspectors examined the airplane following the incident and were unable to identify any mechanical anomaly within the engine that would account for the power loss. During the wreckage examination, an inspector noted that the carburetor heat control was in the 'off' position.

Weather Conditions

At the time of the incident, the ambient temperature was 51 degrees Fahrenheit, and the dew point was 43 degrees Fahrenheit. These temperature and dew point values are conducive to the formation of serious carburetor icing.
