## Probable cause

A DELAYED ABORTED TAKEOFF BY THE PILOT IN COMMAND.  A FACTOR IN THE ACCIDENT IS THE PRESENCE OF CARBURETOR ICING CONDITIONS.

## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, takeoff - initial climb
  - powerplant - surge
  - weather condition - carburetor icing conditions (contributing factor)
- Overrun, takeoff - aborted
  - aborted takeoff - delayed, pilot in command (cause)
- On ground/water encounter with terrain/water, takeoff - aborted
  - terrain condition - ditch

## Analysis

THE PILOT OF THE ACCIDENT AIRPLANE ABORTED A TAKEOFF DURING INITIAL CLIMB. ACCORDING TO THE PILOT THE AIRPLANE ENGINE STARTED SURGING AFTER LIFTOFF. HE DECIDED TO LAND AND WAS UNABLE TO STOP THE AIRPLANE ON THE REMAINING PORTION OF THE RUNWAY BEFORE RUNNING OFF THE END AND COLLIDING WITH A DITCH.  A POST ACCIDENT INSPECTION OF THE AIRPLANE AND AN ENGINE TEST RUN DISCLOSED NO DEFECTS.  WEATHER CONDITIONS CONDUCIVE TO THE FORMATION OF CARBURETOR ICE (TEMPERATURE 53 DEGREES, DEWPOINT 29 DEGREES FAHRENHEIT) WERE PRESENT.

## FAA reports on this event (1)

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

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.
