## Probable cause

THE INADVERTENT STALL WHILE EXECUTING THE TURN TO REVERSE DIRECTION DURING AN AERIAL APPLICATION FLIGHT.

## 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
  - stall - inadvertent, pilot in command (cause)
- On ground/water encounter with terrain/water, descent - uncontrolled

## Analysis

ACCORDING TO AN FAA INSPECTOR, THE PILOT REPORTED TO HIM THAT WHILE EXECUTING THE TURN TO REVERSE DIRECTION DURING AN AERIAL APPLICATION FLIGHT 'THE AIRCRAFT WOULDN'T ROLL OUT OF TURN AND BEGAN DESCENDING INTO A PASTURE LEFT WING DOWN AT FULL POWER.' THE AIRPLANE IMPACTED THE GROUND IN A LEFT WING LOW ATTITUDE. POST ACCIDENT EXAMINATION OF THE AIRCRAFT WRECKAGE DID NOT REVEAL ANY ANOMALIES THAT WOULD HAVE PREVENTED NORMAL FLIGHT.

## Factual narrative

On May 15, 1995, at 1252 central daylight time, a Fairchild F-23A, N1133Z, sustained substantial damage following a loss of control while maneuvering near Ozark, Arkansas.  The commercial pilot was not injured.  Visual meteorological conditions prevailed for the aerial application flight.

The pilot reported to a Federal Aviation Administration (FAA) inspector that while executing a turn to reverse direction for a second pass, control was lost and "the aircraft wouldn't roll out of turn and began to descend into a pasture left wing down at full power."

Post accident examination of the aircraft wreckage by the FAA inspector revealed damage to the engine mount, propeller, and left wing.  No anomalies were found during the examination that would have prevented normal operation.

Despite numerous attempts, a completed NTSB Form 6120.1/2 was never received from either the pilot or the operator.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
