## Probable cause

THAT THE PILOT MISJUDGED THE DISTANCE FROM THE WIRES WHICH REQUIRED A RAPID PULL-UP MANEUVER AND HIS FAILURE TO MAINTAIN ADEQUATE FLYING SPEED. CONTRIBUTING TO THIS ACCIDENT WERE THE TRANSMISSION WIRES.

## Sequence of events

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

- Loss of control - in flight, maneuvering - turn to reverse direction
  - object - wire,transmission (contributing factor)
  - distance - misjudged, pilot in command (cause)
  - pull-up - excessive, pilot in command (cause)
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT COMPLETED HIS SWATH RUN AND MISJUDGED THE DISTANCE OF THE TRANSMISSION WIRES. IN ORDER TO AVOID HITTING THE WIRES THE PILOT EXECUTED A RAPID PULL-UP DURING THE 90/270 DEGREE REVERSAL TURN.  THE PILOT FAILED TO MAINTAIN ADEQUATE FLYING SPEED AND THE AIRPLANE SETTLED TO THE GROUND, CARTWHEELED, AND SUBSEQUENTLY BURNED.

## 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 19910801031109A](https://openairdocs.org/incident/19910801031109A), Aug 1, 1991: Eagle DW1, Poston, AZ, Destroyed. Stalled on pull up to miss wires on a spray run. Settled,cartwheeled and burned.

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.
