WHILE ENROUTE TO BIRMINGHAM THE PILOT EXPERIENCED A COMPLETE POWER FAILURE WHEN NO. 2 CYLINDER SEPARATED FROM THE ENGINE ASSEMBLY. THE PILOT ATTEMPTED TO MAKE AN EMERGENCY LANDING ON INTERSTATE 65 NEAR HANCEVILLE, AL, AND THE AIRCRAFTCOLLIDED WITH AN EMBANKMENT ADJACENT TO THE SOUTHBOUND LANES. THE INVESTIGATION DETERMINED THAT THE AIRCRAFT HAD EXPERIENCED SEVERE ENGINE VIBRATIONS TWICE WITHIN THE THREE MONTHS PRIOR TO THE ACCIDENT. ON BOTH OCCURRENCES THE CYLINDERS WERE OVERHAULED AND THE AIRCRAFT RETURNED TO SERVICE. THE MAINTENANCE PERSONNEL WHO REPAIRED THE ENGINE STATED THAT HE DID NOT FOLLOW THE PROCEDURES AS OUTLINED IN THE ENGINE SERVICE MANUAL. THE FAILURE TO RETORQUE AND INSPECT THE ENGINE ASSEMBLY CAUSED THE OTHER CYLINDERS STUDS TO LOOSEN AND EVENTUAL NO. 2 CYLINDER FAILURE.
