NTSB narrative
THE PILOT SAID THAT ABOUT 10 MINUTES AFTER TAKEOFF, AND WHILE CRUISING AT ABOUT 800 FEET AGL, THE RIGHT ENGINE OIL PRESSURE BEGAN DECREASING AND THE TEMPERATURE INCREASING. ABOUT 2 MINUTES LATER THE RIGHT ENGINE STARTED RUNNING ROUGH AND BACKFIRING, SO HE SHUT IT DOWN. MEANWHILE HE MISTAKENLY TURNED INTO A SMALL BAY INSTEAD OF TOWARD HIS DEPARTURE AIRPORT. BECAUSE OF THE HIGH TERRAIN AND HOUSES ON HIS LEFT HE ATTEMPTED A SLOW TURN TO THE RIGHT. WHEN THE AIRPLANE GOT INTO A LOW AIRSPEED BUFFET, AND THE PILOT THOUGHT IT WAS ABOUT TO GO INVERTED, HE CUT POWER ON THE LEFT ENGINE, LEVELED THE WINGS, AND DITCHED IN THE SHALLOW WATER NEAR THE SHORELINE. INVESTIGATION FOUND THAT DURING THE AFTER TAKEOFF GEAR RETRACTION THE RIGHT MAIN LANDING GEAR RETRACTION CHAIN BROKE AND PUNCTURED THE RIGHT ENGINE'S OIL TANK, WHICH ALLOWED ALL THE OIL TO DRAIN OUT. NO MECHANICAL PROBLEMS WERE FOUND WITH EITHER OF THE TWO ENGINES.
Probable cause
THE PILOT'S IMPROPER IN FLIGHT PLANNING/DECISION. A FACTOR WAS THE PARTIAL LOSS OF POWER ON ONE ENGINE.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
