Analysis

The plt noticed smoke in the cockpit & started to make a precautionary lndg at Mexia, TX, which was nearby. However, drg the dscnt to lnd, the smoke dissipated, so he elected to cont to the destn. Drg the climb back to alt, smoke reappeared & was followed by loss of eng power. The plt then tried to make a forced lndg at Mexia; however, there was insufficient alt to reach the arpt. While lndg about 1 mi from the arpt, the acft rolled thru a barbed wire fence & was damaged. An exam of the acft revealed a retaining nut was missing from a clamp near 2 mating surfaces of the exhaustsys near the #6 cylinder. Subsequently, gases from the exhaust sys burned thru a vacuum hose & extensively burned a number of wires in the ignition sys. The acft had been flown 176 hrs since the last eng & airframe inspn.
