## Analysis

THE PILOT WAS ON A SPRAY FLIGHT OVER AN AREA OF SAND HILLS. WHILE DROPPING FLAGS TO HELP DETERMINE THE WIND ON THE SURFACE, HE ENCOUNTERED UNFAVORABLE WIND CONDITIONS AND A SUDDEN LOSS OF LIFT. HE APPLIED FULL POWER, BUT WAS UNABLE TO RECOVER FROM THE MUSHING CONDITION BEFORE HITTING THE GROUND. THE PILOT REPORTED SEVERE TO EXTREME TURBULENCE, A TEMPERATURE OF 85 DEGREES FAHRENHEIT, AND BELIEVED THERE WERE DOWNDRAFTS AND UNUSUAL WIND CIRCULATION AMONG THE SAND DUNES.

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19820617023329A](https://openairdocs.org/incident/19820617023329A), Jun 17, 1982: Airpts A9B, Ulysses, KS, Substantial damage. Pilot was making second pass over field when aircraft hit downdraft and crashed.

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.
