Analysis

During initial climb, the plt smelled smoke & heard a backfire, then the eng lost power. A forced landing was made in a field on rough/uneven terrain. During the landing roll, the acft struck a ditch & was damaged. A visual inspection revealed that the left exhaust muffler had failed at its outlet. This allowed hot exhaust gases to enter the eng compartment & damage the voltage regulator, alternator & magneto wiring (p-leads). With p-lead failure, the magnetos would have been inoperative. An airworthiness directive, AD 76-23-03, which required an inspection of the exhaust sys each 100 hrs, had last been complied with on 8/18/82. However the acft had been operated for only 50 flt hrs since that date.
