## NTSB investigations (1)

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.

- [NTSB SEA93LA210](https://openairdocs.org/ntsb/SEA93LA210), Sep 25, 1993: White BD-5 (N273GW), Helena, MT, substantial damage. Probable cause: THE PILOT'S FAILURE TO MAINTAIN AIRSPEED. THE PILOT'S LACK OF EXPERIENCE IN THIS MAKE AND MODEL AIRCRAFT WAS A FACTOR.
