## Probable cause

THE LOSS OF ENGINE POWER DUE TO FUEL STARVATION RESULTING FROM THE PILOT'S INADEQUATE PREFLIGHT INSPECTION.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, maneuvering - aerial application
  - fuel system,vent - blocked(total)
  - maintenance,service of aircraft/equipment - inadequate, company/operator management (contributing factor)
  - fluid,fuel - starvation (cause)
  - aircraft preflight - inadequate, pilot in command (cause)
- In flight collision with terrain/water, maneuvering - aerial application
- Nose over, landing - roll
  - terrain condition - crop

## Analysis

THE PILOT EXPERIENCED A LOSS OF ENGINE POWER DURING THE PULL-UP FOR A REVERSAL TURN IN AN AERIAL APPLICATION MANEUVER.  PILOT MADE A FORCED LANDING IN A FIELD, AND THE AIRCRAFT NOSED OVER DURING LANDING ROLLOUT. THE FUEL SELECTOR WAS IN THE RIGHT TANK POSITION.  THE INVESTIGATION REVEALED THAT THE RIGHT FUEL TANK VENT WAS COMPLETELY BLOCKED BY AN INSECT'S NEST.

## Other investigations on N7761V (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.
