## Probable cause

THE FAILURE OF THE PILOT-IN-COMMAND TO TOUCHDOWN IN A SUITABLE AREA AFTER HE EXPERIENCED A POWER LOSS.   A FACTOR RELATED TO THE ACCIDENT WAS THE IMPROPERLY MAINTAINED CARBURETOR.

## Sequence of events

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

- Loss of engine power, maneuvering
  - fuel system,carburetor float - other (contributing factor)
  - maintenance,calibration - improper, unknown
- Forced landing, descent - emergency
- Undershoot, landing - flare/touchdown
  - planned approach - exceeded, pilot in command(cfi) (cause)
  - proper touchdown point - not attained, pilot in command(cfi) (cause)
- Main gear collapsed, landing
  - terrain condition - rough/uneven

## Analysis

THE CFI WAS CHECKING OUT A PRIVATE PILOT.  THEY WERE DOING STALLS WHEN THE PROPELLER STOPPED.  THE AIRPLANE DID NOT HAVE A STARTER AND THEY TRIED TO GET THE PROPELLER WINDMILLING BUT WERE UNSUCCESSFUL.  THE FAA REPORTED THE PILOT LANDED 30 FT. SHORT OF A 4000 FT FIELD WHICH COLLAPSED THE LANDING GEAR.  ADDITIONALLY, THE FAA REPORTED THE CARBURETOR FLOAT WAS IMPROPERLY SET WHICH CAUSED AN OVERLY RICH MIXTURE AT VARIOUS POWER SETTING.  THEY OBSERVED BLACK SMOKE COMING OUT OF THE EXHAUSTS BETWEEN IDLE AND 1400 RPM/

## 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 19910204001629A](https://openairdocs.org/incident/19910204001629A), Feb 4, 1991: Piper J3C65, Hamilton, OH, Substantial damage. Engine stopped on stall demo. Landed 30 feet short of a 4000 foot field. Carburetor float set too rich.

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.
