## 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 LAX02IA013](https://openairdocs.org/ntsb/LAX02IA013), Oct 23, 2001: McDonnell Douglas 600N (N959SD), Long Beach, CA, incident, no damage. Probable cause: The fatigue failure of a 5/16-inch boom attach bolt was most probably caused by the angular misalignment between the tail boom bolt hole and the fuselage mounted nutplate.
