## Probable cause

IMPROPER PREFLIGHT BY THE PILOT WHICH RESULTED IN AN INADEQUATE FUEL SUPPLY AND FUEL EXHAUSTION.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise
  - aircraft preflight - improper, pilot in command (cause)
  - fluid,fuel - exhaustion (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing - flare/touchdown

## Analysis

THE PILOT SAID THAT WHILE FLYING AN EXPERIMENTAL COZY ACFT ON A LOCAL FLIGHT, THE ENGINE QUIT. AN EMERGENCY LDG WAS ATTEMPTED IN A FARM FIELD AND THE LEFT GEAR WAS TORN OFF AND THE WINGS DAMAGED IN ADDITION TO OTHER SUBSTANTIAL DAMAGE. POST ACCIDENT INVESTIGATION REVEALED THE FUEL TANKS WERE EMPTY.

## 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 19890225004149A](https://openairdocs.org/incident/19890225004149A), Feb 25, 1989: Amtrcz COZY, Hudson, IA, Substantial damage. Engine stopped on local flight. Struck ground left gear and wing first on forced landing. Fuel tanks were empty.

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.
