## Narrative

PILOT OPERATED AIRCRAFT IN VMC CONDITIONS CONDUCIVE TO INDUCTION ICING FOR APPROXIMATELY 1-1/2 HOURS.  AS PILOT WAS PREPARING FOR FINAL APPROACH TO FALMOUTH AIRPARK, PILOT SELECTED CARB HEAT.  ON SELECTING CARB HEAT,  THE ENGINE RPM FLUCTUATED.  PILOT IMMEDIATELY DE-SELECTED CARB HEAT AND THE ENGINE QUIT OPERATING.  DUE TO THE AIRCRAFT'S LOW ALTITUDE, PILOT ACCOMPLISHED LIMITED TROUBLESHOOTING BEFORE PREPARING FOR AN EMERGENCY LANDING.  OPTIONS WERE A POPULATED BEACH, TREES, OR WATER.  PILOT ELECTED TO LAND APPROXIMATELY 30 YARDS OFFSHORE OF SOUTH CAPE BEACH.  A POST-ACCIDENT ENGINE INSPECTION DID NOT SHOW ANY FAILED ENGINE COMPONENTS.

## The NTSB's investigation of this event (1)

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.
