## 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 SEA08LA178](https://openairdocs.org/ntsb/SEA08LA178), Aug 14, 2008: Kolb Mark III (N18EX), Richland, WA, substantial damage, 1 fatal. Probable cause: The pilot's failure to maintain an adequate airspeed above stall speed while executing a steeply banked turn in the traffic pattern.
