## Analysis

DURING A TEST FLIGHT FOR CERTIFICATION OF WING TIP TANKS, WHILE PERFORMING SPINS, THE AIRCRAFT ENTERED A FLAT SPIN. THE PILOT WAS UNABLE TO REGAIN CONTROL AND EXITED THE AIRCRAFT AND PARACHUTED TO SAFETY. THE AIRCRAFT COLLIDED WITH THE TERRAIN SHORTLY THEREAFTER. THERE WERE NO MECHANICAL FAILURES OR MALFUNCTIONS REPORTED AT THE TIME OF THE ACCIDENT.

## 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 19880225003889A](https://openairdocs.org/incident/19880225003889A), Feb 25, 1988: Beech STC36, Ramona, CA, Destroyed. Flat spin developed on spin test for STC. Unable to recover test pilot bailed out and landed safely.

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.
