## Sequence of events

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

- Loss of engine power(total) - nonmechanical, approach - vfr pattern - downwind
  - fuel system - starvation (contributing factor)
  - operation with known deficiencies in equipment - attempted, pilot in command (contributing factor)
  - in-flight planning/decision - poor, pilot in command (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll
  - terrain condition - soft

## Analysis

THE PILOT MADE A STEEP RIGHT BANK WHILE ENTERING THE DOWNWIND LEG ON APPROACH TO LAND WHEN THE ENGINE QUIT AND THE PILOT WAS FORCED TO MAKE AN EMERGENCY LANDING IN A FIELD SHORT OF THE RUNWAY. UPON EXAMINATION OF THE FUEL SYSTEM THERE WAS A LACK OF FUEL IN THE LINES BETWEEN THE IN-LINE FUEL FILTER, ELECTRIC FUEL PUMP, ENGINE DRIVEN FUEL PUMP AND CARBURETOR. THE FUEL SYSTEM WAS PURGED OF AIR BY LOOSENING THE FUEL LINE AT THE CARBURETOR AND HAND CRANKING THE ENGINE. THE ENGINE WAS THEN STARTED AND RAN SATISFACTORILY. THE BUILDER OF THE EXPERIMENTAL AIRCRAFT STATED THAT IT HAD BEEN HIS EXPERIENCE THAT DURING A STEEP BANKED RIGHT OR LEFT TURN THE FUEL WILL PULL AWAY FROM THE FUEL SUMP OUTLET OF THE ENGINE, ALLOWING AIR TO ENTER THE FUEL LINES.

## 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 19860828044389A](https://openairdocs.org/incident/19860828044389A), Aug 28, 1986: Amtrru VARIEZELONG, Plainfield, IL, Substantial damage. The engine lost power after a steep turn on downwind. Excessive bank caused fuel unporting and air into fuel line.

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.
