## Probable cause

IMPROPER IN-FLIGHT PLANNING/DECISION BY THE PILOT WHICH RESULTED IN A TIGHT MANEUVER AT INADEQUATE AIRSPEED AND A SUBSEQUENT STALL. A CONTRIBUTING FACTOR WAS THE PRESENCE OF HIGH OBSTRUCTIONS (TREES).

## 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
  - in-flight planning/decision - improper, pilot in command (cause)
  - terrain condition - high obstruction(s) (contributing factor)
  - maneuver - excessive, pilot in command (cause)
  - airspeed - inadequate, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACFT WAS OBSERVED ON A FINAL SWATH RUN (TO THE NORTH) ALONG THE WEST SIDE OF A RICE FIELD. AT THE END OF THE SWATH RUN, THE ACFT ENTERED A CLIMB OVER A WOODED AREA & THE PLT BEGAN A STEEP LEFT TURN TO MANEUVER THE ACFT FOR A TRIM PASS OVER THE NORTH EDGE OF THE FIELD. A WITNESS RPRTD THAT ABOUT 3/4 OF THE WAY THRU THE TURN, THE ACFT APPEARED TO SNAP-ROLL. IT THEN ENTERED A NEAR VERTICAL DESCENT & CRASHED. APRX 33 MI SOUTH AT JONESBORO, AR, THE 1051 CDT WIND WAS FROM 050 AT 7 KTS. NO PRE-ACDNT MALFUNCTION OR FAILURE OF THE ACFT OR ENG WAS FOUND.

## 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 19890705019719A](https://openairdocs.org/incident/19890705019719A), Jul 5, 1989: Ayres S2RR1340REST, Reyno, AR, Destroyed, 1 fatal. Stalled in a steep turn around while spraying a field. Crashed into trees and burned. Classic accelerated stall.

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.
