## Analysis

THE ACFT CRASHED IN THE GULF OF MEXICO WHILE THE PLT WAS ON A NIGHT X-COUNTRY FLT. THE WX AT THE DESTINATION HAD BEEN FORCAST TO BE IFR. HOWEVER, IN THE AREA OF THE ACCIDENT, WITNESSES STATED THE WX WAS GOOD WITH NO FOG & IT WAS A DARK NIGHT. WHEN THE ACFT DID NOT ARRIVE, A SEARCH WAS INITIATED. THE WRECKAGE WAS FOUND THE NEXT DAY AT 1106 EST WHERE THE ACFT CRASHED ABOUT 3 MI SOUTH OF HORSESHOE BEACH. NO PREIMPACT PART FAILURE OR MALFUNCTION WAS FOUND. RADAR DATA SHOWED THAT THE ACFT HAD ENTERED A SPIRAL BEFORE CONTACT WAS LOST IN THE VICINITY OF THE CRASH SITE. A CHECK OF THE PLT'S BLOOD SHOWED A SLIGHT AMOUNT OF ALCOHOL; HOWEVER, SOME OR ALL OF THIS COULD HAVE BEEN ATTRIBUTED TO PUTREFACTION.
