The NTSB's narrative final · quoted from the NTSB record

THE CREW OF AN ALL CARGO FLIGHT EXPERIENCED A FAILURE OF THE LEFT ENGINE WHILE IN THE TRAFFIC PATTERN AT THEIR DESTINATION. THEY RAISED THE LANDING GEAR BUT FAILED TO FEATHER THE LEFT PROPELLER AND FAILED TO TRIM THE AIRCRAFT. THE RESULTING SKID AND INCREASED DRAG MADE FURTHER FLIGHT IMPOSSIBLE. THE CREW ELECTED TO DITCH THE AIRCRAFT IN A LAGOON ABOUT 2 MILES SOUTHWEST OF THE AIRPORT. THE AIRCRAFT WAS NOT RECOVERED FROM THE LAGOON AND THEREFORE IT WAS NOT DETERMINED WHY THE LEFT ENGINE LOST POWER.
