## Analysis

FOLLOWING THE TAKEOFF FROM A PRIVATE STRIP NEAR WYNNE, ARKANSAS, THE PILOT REPORTED THAT HE FAILED TO ESTABLISH AND MAINTAIN AN ADEQUATE ANGLE OF CLIMB WITH THE HEAVILY LOADED CONDITION OF THE AIRCRAFT. THE AIRCRAFT IMPACTED TREES IN THE FLIGHT PATH, THEN COLLIDED WITH THE TERRAIN. A POST-IMPACT FIRE OCCURRED.

## 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 19880606019179A](https://openairdocs.org/incident/19880606019179A), Jun 6, 1988: Scwzer G164A, Wynne, AR, Substantial damage. Realized after takeoff aircraft would not clear trees. Dumped load and tried to turn away but crashed into 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.
