## Probable cause

THE PILOT'S FAILURE TO ENSURE AN ADEQUATE SUPPLY OF FUEL, WHICH RESULTED IN 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, descent - normal
  - fluid,fuel - exhaustion (cause)
  - fuel supply - inadequate, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing - flare/touchdown

## Analysis

THE PILOT REDUCED POWER TO DESCEND FOR LANDING AT HIS AIRSTRIP AFTER COMPLETING AN AERIAL APPLICATION FLIGHT AND THE ENGINE QUIT DUE TO FUEL EXHAUSTION. THE ACFT IMPACTED AGRICULTURAL IRRIGATION EQUIPMENT DURING THE ENSUING FORCED LANDING.

## 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 19900715027099A](https://openairdocs.org/incident/19900715027099A), Jul 15, 1990: Ayres S2RR1340REST, Royal City, WA, Substantial damage. Ran out of fuel on final for ag strip. Dived under powerlines but struck an irrigation sprinkler and crashed.

## Other investigations on N8468V (3)

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.
