On July 25, 1985, a Beech 58P (registration N6039S) was involved in an aviation accident near Buena Vista, CO. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During takeoff at about 40 ft AGL, the left engine failed. The pilot applied incorrect emergency procedures and lost control during the forced landing. Inspection revealed a blocked air filter, misaligned air box, and a bogus gasket.
Accident Description
During the takeoff roll, the aircraft experienced a failure of the left engine at an altitude of approximately 40 feet above ground level (AGL). In response, the pilot initiated a forced landing. During the landing, the pilot employed incorrect emergency procedures and was unable to maintain lateral and directional control of the aircraft.
Inspection Findings
A post-accident inspection of the aircraft revealed several issues related to the left engine induction system. The left engine induction air filter had disintegrated, and the resulting debris blocked the air box outlet. Additionally, the air box was found to be misaligned, which prevented the actuation of the alternate air source door. A bogus gasket had been installed between the air box flange attachment and the firewall.
