Aircraft Accident/Incident Report

Wonder Lake, Illinois 60097
Saturday, September 14, 1996 13:00 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that during climb out after takeoff the engine sustained a partial loss of power. The pilot executed an emergency landing in a corn field approximately three quarters of a mile from the airport. A weld repair had been performed on the muffler. Another pipe on the muffler was cracked, and brown residue was around the crack. The internal baffling inside the muffler was broken loose, and pieces of the baffling were missing. The exhaust pipe which had been welded was broken loose from the internal baffling. The aircraft's manufacturer does not recommend welding any exhaust system components, and the aircraft's logbook had an entry on 10/20/95 which read 'welded crack in muffler.'

NTSB Probable Cause Narrative

a blocked exhaust pipe as a result of an inadequate weld repair to the muffler.
