SH36 CREW HAD AN ENG FAILURE IN LEX CLASS E.

Narrative

JUN/FRI/03; XA00Z; PASSING OVER LEX; WE WERE IN CRUISE. LEX ATC SAID 'ARC X; DSND; MAINTAIN 6000 FT.' BEFORE I TOUCHED THE PWR OR PITCHED DOWN FOR THE DSCNT; THERE WAS A 'POP.' THE L ENG SEIZED AND AUTO FEATHER KICKED IN. MY FO AND I WENT THROUGH THE PROPER CHKLISTS FOR VITAL ACTIONS FOR ENG FAILURE. WE THEN ADVISED ATC THAT WE HAD A L ENG FAILURE. LEX APCH WAS VERY PROMPT. WE ADVISED THAT WE WANTED TO STAY AT A HIGH ALT AND DIVERT TO BOWMAN FIELD. WE WERE HANDED TO SDF APCH. THEY GAVE US DISCRETION DSCNTS AND GOOD VECTORS -- VERY ACCOMMODATING. WE SECURED THE FAILED ENG AFTER A FAILED AIR START. AS WE WERE LINED UP FOR BOWMAN; I REALIZED THE PLANE WAS MAINTAINING ALT AND DRIFT DOWN WAS NOT A THREAT; SO DECIDED SDF WAS SAFER TO LAND AT -- BETTER EMER VEHICLES; LONGER RWY; ETC. SO; WE CHANGED DEST TO SDF. WE LANDED FINE AND REQUESTED TO TAXI WITHOUT DELAY; SO I WOULD NOT GET STUCK (I HAVEN'T TAXIED ON 1 ENG FOR ANY LENGTH OF TIME). I AM STILL WAITING ON THE CAUSE OF THE FAILURE. THE ENGS WERE BOTH RUNNING WITHIN COMPANY LIMITS; WHICH IS MORE STRICT THAN PRATT & WHITNEY LIMITS. I HEARD SPECULATIONS ABOUT A BAD FUEL CTL UNIT; BUT STILL DON'T KNOW. I GNDED THE PLANE IN SDF; AND IT'S BEING REPAIRED BY THE FBO. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: CREW WAS FLYING A SH36 ACFT. RPTR SAID THE ENG DRIVEN HIGH PRESSURE FUEL PUMP FAILED. THE PUMP WAS REPLACED; AND THE ACFT HAS NOT HAD AN ENG PROB SINCE.
