WHILE DESCENDING THRU 4300 FT, THE ENG LOST POWER. THE PLT MADE AN EMERGENCY LANDING ON A GULF COURSE, BUT DURING THE LANDING ROLL, THE RIGHT WING OF THE ACFT IMPACTED A POLE & WAS DAMAGED. AN EXAM REVEALED THAT THE 5/16 INCH BOLT, PN STD-847, THAT SECURED THE CRANKSHAFT GEAR TO THE AFT END OF THE CRANKSHAFT HAD BACKED OUT. THIS RESULTED IN SHEARING OF THE DOWL PIN. IN TURN, THE CRANKSHAFT COULD NOT DRIVE THE ACCESSORIES, WHICH INCLUDED THE MAGNETOS & VACUUM PUMP. THE ENG HAD OPERATED 371 HRS SINCE OVERHAUL.
