## Probable cause

FUEL STARVATION CAUSED BY FUEL CONTAMINATION.

## Sequence of events

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

- Loss of engine power, maneuvering
  - fluid,fuel - contamination (cause)
  - fluid,fuel - starvation (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - crop (contributing factor)

## Analysis

WHILE FLYING HIS NEWLY BUILT HOMEBUILT AIRCRAFT, THE PLT SAID HE EXPERIENCED A PROGRESSIVE POWER FAILURE. AN EMERGENCY DESCENT WAS MADE INTO A BEAN FIELD RESULTING IN SUBSTANTIAL DAMAGE TO THE ACFT AND MINOR INJURIES TO THE PLT. POST ACCIDENT INVESTIGATION REVEALED SOME FIBERGLASS CONTAMINANTS IN THE FUEL LINE WHICH WOULD CAUSE FUEL STARVATION.

## Other investigations on N1066 (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.

- [NTSB CHI92DCD01](https://openairdocs.org/ntsb/CHI92DCD01), Feb 3, 1992: Raymond Bristow Rand KR-2 (N1066), Boone, IA, destroyed, 1 fatal. Probable cause: FAILURE OF THE PILOT TO MAINTAIN AIRCRAFT CONTROL. A FACTOR IN THE ACCIDENT IS TOTAL FAILURE OF THE AIRPLANE CANOPY.
