## Analysis

RADAR TRACK SHOWS C195 PLT WAS DESCENDING INTO CONGESTED AIRSPACE AT ABOUT 192 MPH, ABOVE MAX STRUCTURAL CRUISE SPEED OF 178 MPH, LESS THAN 1 MIN FROM TRAFFIC PATTERN ENTRY. RADAR DATA AND WITNESS CONFIRM A SECOND ACFT IN PROXIMITY, ENGAGED IN AEROBATICS. WHILE MANEUVERING, C195 PLT EXCEEDED DESIGN LIMITS AND ACFT RT WING FAILED IN STRUCTURAL OVERLOAD.

## 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 19860201044589A](https://openairdocs.org/incident/19860201044589A), Feb 1, 1986: Cessna 195A, Black Diamond, WA, Destroyed. Outer 5 feet of wing broke off during a high speed descent. Radar indicates aircraft at or near red line speed.

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.
