PA23-160 PLT HAS WATER IN FUEL CAUSING ENG FAILURE. EMER LNDG OFF ARPT LNDG.

Narrative

NORMAL VFR DEP FROM LITTLE ROCK; CLBOUT TO 4000 FT; THEN WAS RELEASED BY LIT DEP; ENCOUNTERED TURB JUST AFTER SWITCHING FUEL FROM MAIN TO AUX ON BOTH TANKS. HAD FOUND WATER DURING PREFLT IN ALL TANKS AND DRAINED UNTIL CLR OF WATER. R ENG SPUTTERED AND LOST PWR. SWITCHED BACK TO MAINS; FEATHERED R ENG AUTOMATIC AND ATTEMPTED RESTART. NO RESTART; HAD TURNED 180 DEGS TO RETURN TO NEAREST ARPT; CONWAY 12 MI. AT 8 MI OUT L ENG BEGAN TO SPUTTER AND LOST PWR DUE TO WATER INGESTION. TRIED TO KEEP ENG RUNNING SO AS TO PASS WATER; BUT NOT ABLE TO MAINTAIN ALT. LOCATED SUITABLE PASTURE FOR LNDG. LANDED WITH NO PROPERTY DAMAGE. NO INJURY. THE PROB WHICH NEEDS TO BE ADDRESSED IS THAT THE SUMP SYS FOR CLRING WATER FROM THIS ACFT WILL NOT CLR THE SYS OF ALL THE WATER. REPEATED DRAINING STILL LEAVES WATER IN THE AREA BELOW THE PICKUPS AND IN CARB BOWLS. TURB WILL CAUSE THIS WATER TO BE INGESTED INTO THE ENGS CAUSING LOSS OF PWR OR COMPLETE FAILURE. THERE SHOULD BE AN AIRWORTHINESS DIRECTIVE REQUIRED ON THESE ACFT FOR ADDITIONAL FUEL DRAINS AND CARB DRAINS. TYPE OF ACFT PA23-160.
