## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power, cruise - normal
  - reason for occurrence undetermined, pilot in command (cause)
- Ditching, descent - emergency

## Analysis

BEFORE THE ACCIDENT THE ACFT HAD NOT BEEN FLOWN FOR 4 MONTHS.  THE FLT DEPARTED & PROCEEDED OFFSHORE DUE TO REPORTED CONGESTION OVER LAND.  THE FLT WAS 14 MILES OFFSHORE WHEN THE ENG QUIT.  THE PLT WAS UNABLE TO RESTART IT & DITCHED THE ACFT WHICH BECAME INVERTED AFTER TOUCHDOWN.  THE PLT EXITED THE ACFT & WAS RESCUED BY A NEARBY BOAT.  THE ACFT WAS NOT RECOVERED; THEREFORE, NO DETERMINATION COULD BE MADE AS TO THE REASON FOR THE REPORTED LOSS OF ENG POWER.
