I was flying my A36 bonanza on a mid-day solo return flight of approximately 40 NM distance from lantana (lna) fl, to home field, 64X near stuart (a 40 NM distance). I had been with flight following from pbi approach control when the engine lost partial power and ran rough. I was just north of the jupiter inlet at 1000 ft over the shoreline when this happened, and notified pbi approach control of my problem. I asked for a vector to north county airport, F45, (which the controller promptly provided). Not knowing specifically what the engine problem was and being barely able to climb at 200 FPM on full power, I declared an emergency to pbi approach. I landed without difficulty at F45. Inspection on the ground indicated that the #5 cylinder head had separated just above the barrel. The cylinder is being replaced along with the associated exhaust manifold, which also cracked. Cylinder pressures taken only 10 hours before and oil change on april with routing oil analysis and oil filter inspection gave no indication of any engine problems.

Title: PLT OF A BEECH A36 LOST PWR AT 1000 FT CRUISE OFF SHORE CAUSING HIM TO REQUEST ASSISTANCE FOR VECTORS FROM APCH CTL TO THE NEAREST ARPT.
Narrative: I WAS FLYING MY A36 BONANZA ON A MID-DAY SOLO RETURN FLT OF APPROX 40 NM DISTANCE FROM LANTANA (LNA) FL, TO HOME FIELD, 64X NEAR STUART (A 40 NM DISTANCE). I HAD BEEN WITH FLT FOLLOWING FROM PBI APCH CTL WHEN THE ENG LOST PARTIAL PWR AND RAN ROUGH. I WAS JUST N OF THE JUPITER INLET AT 1000 FT OVER THE SHORELINE WHEN THIS HAPPENED, AND NOTIFIED PBI APCH CTL OF MY PROB. I ASKED FOR A VECTOR TO N COUNTY ARPT, F45, (WHICH THE CTLR PROMPTLY PROVIDED). NOT KNOWING SPECIFICALLY WHAT THE ENG PROB WAS AND BEING BARELY ABLE TO CLB AT 200 FPM ON FULL PWR, I DECLARED AN EMER TO PBI APCH. I LANDED WITHOUT DIFFICULTY AT F45. INSPECTION ON THE GND INDICATED THAT THE #5 CYLINDER HEAD HAD SEPARATED JUST ABOVE THE BARREL. THE CYLINDER IS BEING REPLACED ALONG WITH THE ASSOCIATED EXHAUST MANIFOLD, WHICH ALSO CRACKED. CYLINDER PRESSURES TAKEN ONLY 10 HRS BEFORE AND OIL CHANGE ON APRIL WITH ROUTING OIL ANALYSIS AND OIL FILTER INSPECTION GAVE NO INDICATION OF ANY ENG PROBS.
