## Sequence of events

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

- In flight encounter with weather, takeoff - initial climb
  - weather condition - downdraft (contributing factor)
  - weather condition - high density altitude (contributing factor)
- Loss of control - in flight, takeoff - initial climb
  - stall/mush - intentional, pilot in command (cause)
  - weather evaluation - inadequate, pilot in command (cause)
- In flight collision with object, descent - uncontrolled
  - object - tree(s)

## Analysis

N5593C TOOK OFF ON RWY 25 WHICH HAS A HILL OFF THE WEST END. THE WIND WAS FROM THE WEST AT 10 TO 13 KNOTS AND THE TEMPERATURE WAS 95 DEG F. THE PLT SAID THE ACFT ENCOUNTERED  A DOWNDRAFT AS IT APPROACHED THE HILL DURING THE INITIAL CLIMB. THE PLT BECAME CONCERN ABOUT CLEARING TREES BEYOND THE HILL AND DECIDED TO INTENTIONALLY STALL THE ACFT INTO THE TREES.

## 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 19850714065089A](https://openairdocs.org/incident/19850714065089A), Jul 14, 1985: Cessna 170A, Camdenton, MO, Destroyed. Lowered flaps and stalled into trees after pilot felt he could not clear hill. 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.
