## Probable cause

THE PILOT'S FAILURE TO USE CARBURETOR HEAT, RESULTING IN CARBURETOR ICE AND LOSS OF ENGINE POWER AND SUBSEQUENT FORCED LANDING IN THE OCEAN.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise - normal
  - weather condition - carburetor icing conditions
  - carburetor heat - improper use of, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing
  - terrain condition - water

## Analysis

THE PILOT WAS CRUISING AT 2500 FEET, WHEN THE LEFT ENGINE QUIT, FOLLOWED SHORTLY BY THE RIGHT ENGINE.  HE MADE A QUICK, UNSUCCESSFUL ATTEMPT TO RESTART THE ENGINES AND THEN CONCENTRATED ON EXECUTING A FORCED LANDING IN THE OCEAN. THE AIRPLANE WAS RECOVERED, AND AFTER REPLACING THE SALT WATER DAMAGED MAGNETOS AND FUEL PUMP, THE LEFT ENGINE WAS RUN FROM IDLE TO FULL POWER USING FUEL THAT WAS IN THE TANK.  THE PILOT SAID THAT HE DID NOT USE CARBURETOR HEAT DURING THE FLIGHT.  THE TEMPERATURE/DEW POINT WAS 66/59 DEGREES F.  THE FAA CHART FOR CARBURETOR ICING PROBABILITY SHOWNS A MODERATE CHANCE OF ICING AT CRUISE POWER FOR THIS TEMPERATURE/DEW POINT COMBINATION.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19920813031259A](https://openairdocs.org/incident/19920813031259A), Aug 13, 1992: Beech 76, Hyannis, MA, Substantial damage. Lost both engines five minutes after takeoff. Ditched in ocean. No defects found. Fuel exaustion or carburetor ice.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
