## Sequence of events

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

- In flight collision with object, maneuvering - turn to reverse direction
  - object - tree(s) (contributing factor)
  - in-flight planning/decision - inadequate, pilot in command (contributing factor)
  - proper altitude - not maintained, pilot in command (cause)
  - clearance - inadequate, pilot in command (cause)
- In flight collision with terrain/water, maneuvering - turn to reverse direction
  - terrain condition - ground (contributing factor)

## Analysis

DURING AN AGRICULTURAL SPRAY MANEUVER BACK TO A FIELD THE PIC WAS FERTILIZING, THE PIC STATED HE ALLOWED THE ACFT TO BECOME TOO SLOW AND THE AIRCRAFT DESCENDED INTO TREES WHICH BORDERED THE FIELD. THE PIC STATED HE SHOULD HAVE BEEN FLYING WITH A LIGHTER LOAD OR SHOULD HAVE ADDED PWR SOONER IN THE TURN TO MAINTAIN OBSTACLE CLEARANCE ALTITUDE.

## 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 19860514017609A](https://openairdocs.org/incident/19860514017609A), May 14, 1986: Ayres S2RR1340REST, Stuttgart, AR, Destroyed. Airspeed was too low in a turn after the spraying run. Dumped the load,added full power but settled into the trees.

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.
