## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRCRAFT CONTROL AND THE INADVERTENT STALL. A FACTOR WAS THE PILOT'S DIVERTED ATTENTION IN THE COCKPIT.

## Sequence of events

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

- Loss of control - in flight, maneuvering - aerial application
  - fluid,oil - pressure too low
  - aircraft control - not maintained, pilot in command (cause)
  - diverted attention, pilot in command (contributing factor)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - altitude - inadequate

## Analysis

THE PILOT'S ATTENTION WAS DIVERTED TO INSIDE THE COCKPIT FROM A LOW OIL PRESSURE CONDITION AFTER HE MANEUVERED FROM AN AGRICULTURAL SWATH RUN. AS HE ATTEMPTED TO ADJUST THE ENGINE CONTROLS FOR THE CONDITION, THE AIRPLANE STALLED AND DESCENDED UNCONTROLLED INTO A COTTON FIELD. THE PILOT STATED THE AIRPLANE HAD REACHED 300 FEET AGL WHEN THE STALL OCCURRED AND HE DID NOT HAVE ENOUGH ALTITUDE TO RECOVER BEFORE IMPACT. THE USABLE OIL QUANTITY FOR THE ENGINE IS 16 QUARTS. FOUR QUARTS OF OIL WERE DRAINED FROM THE ENGINE BY THE FAA INSPECTOR AND RECOVERY PERSONNEL AT THE ACCIDENT SITE.

## 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 19921006055569A](https://openairdocs.org/incident/19921006055569A), Oct 6, 1992: Cessna A188B, Montrose, AR, Substantial damage. Stalled during spray run turn around by diverting attention to adjust power and propeller.

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.
