## 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
  - aircraft performance,turn capability - exceeded (cause)
  - flight controls - improper use of, pilot in command (cause)
  - weather condition - temperature extremes (contributing factor)
  - performance data - not used, pilot in command (cause)
  - maneuver - excessive, pilot in command (cause)
  - stall - uncontrolled, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
  - object - tree(s) (contributing factor)

## Analysis

THE ACFT COLLIDED WITH TREES AND THE GROUND AFTER STALLING DURING A PULL-UP WHILE MANEUVERING FOR AERIAL APPLICATION. IT WAS A HOT DAY AND THE ACFT HAD RECENTLY BEEN LOADED. THE PLT ADVISED TO 'BEWARE OF DENSITY ALTITUDE AND TURNING HARD OVER TREES.' THIS ACFT ALSO HAD AN EXTENDED WING WHICH REDUCED ROLL RATE BUT SHOULD INCREASE LOAD LIFTING. THE PLT SAID THE ACCIDENT WAS PILOT ERROR.

## 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 19840721034629A](https://openairdocs.org/incident/19840721034629A), Jul 21, 1984: Ayres S2RRESTD, Bryan, TX, Destroyed. Stalled during a pull up from a spray run. Went thru trees prior to ground impact. Density altitude a factor.

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.
