SHORTLY AFTER THE PLT DEPARTED ON A FLT, THE ENG LOST POWER WHILE THE ACFT WAS CRUISING AT 1800 FT MSL OVER HILLY TERRAIN. THE PLT REPORTED THAT THE ENG SPEED DROPPED TO 800 RPM & HE WAS UNABLE TO CORRECT THE SITUATION. DURING A FORCED LANDING ON SOFT TERRAIN, THE ACFT ENCOUNTERED A DITCH & NOSED OVER. AN EXAM OF THE ACFT REVEALED THAT A SELF LOCKING, NAS679A3, SAFETY NUT HAD SEPARATED & THE RESPECTIVE BOLT HAD BACKED OUT, DISCONNECTING THE THROTTLE LINKAGE. THE NUT HAD 2569 OPERATIONAL HRS IN SERVICE & THE ACFT HAD FLOWN 44 HRS SINCE THE LAST ANNUAL INSPECTION. CESSNA SERVICE LETTER, SE 76-6, DATED 4/16/79, RECOMMENDED THAT THE NAS679A3 NUT BE REPLACED BY AN AN310 CASTELLATED NUT & COTTER PIN. AS OF THE DATE OF THE ACCIDENT, NO AIRWORTHINESS DIRECTIVE HAD BEEN ISSUED TO REQUIRE THE CHANGE.
