On July 31, 1990, a Champion 7EC (registration N8575E) operated by Henry A. Ottawella was involved in an aviation accident near Peebles, OH. Investigators recorded the probable cause as: IMPROPER USE OF CARBURETOR HEAT. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot experienced gradual engine power loss during cruise, applied carburetor heat, and made a forced landing in a soybean field. The aircraft struck a drainage ditch and nosed over. Post-accident examination found no pre-impact mechanical issues; weather was conducive to carburetor ice.
Accident Details
During cruise flight, the pilot observed a gradual reduction in engine power. In response, carburetor heat was applied. When the power loss continued, the pilot shut off the carburetor heat again. A forced landing was executed in a soybean field. During the landing roll, the airplane encountered a drainage ditch and nosed down.
Post-Accident Examination
Following the accident, a thorough examination of the engine and its accessories revealed no evidence of any malfunction that existed prior to impact. All components appeared to be functioning normally at the time of examination.
Weather Conditions
FAA inspectors noted that the weather conditions at the time of the accident were conducive to the formation of carburetor ice. This observation was based on standard meteorological factors.
