## Probable cause

THE LOSS OF ENGINE POWER WHEN IT OVERHEATED DUE TO LOW COOLANT LEVEL, WHICH RESULTED FROM THE INADEQUATE PREFLIGHT INSPECTION BY THE PILOT.  A FACTOR RELATING TO THE ACCIDENT WAS THE OBSTRUCTION IN THE LANDING AREA.

## 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
  - fluid,coolant - low level (cause)
  - aircraft preflight - inadequate, pilot in command (cause)
  - cooling system - overtemperature (cause)
- Nose over, landing - roll
  - airport facilities,runway/landing area condition - hidden obstruction(s) (contributing factor)

## Analysis

THE ENG QUIT IN CRUISE FLT WHEN IT OVERHEATED AND THE PILOT MADE AN EMERGENCY FORCED LDG IN AN OPEN FIELD.  THE ACFT IMPACTED A LOG DURING LDG GND ROLL AND NOSED OVER.  EXAM OF THE ACFT REVEALED THE LIQUID COOLANT FOR THE ENG WAS LOW.

## 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 19911123053339A](https://openairdocs.org/incident/19911123053339A), Nov 23, 1991: Amtrdf KITFOX, West Jordan, UT, Substantial damage. Engine overheated in flight. Struck a log and overturned on precautionary landing. Forgot to service coolant.

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.
