## NTSB investigations (4)

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 MIA08CA072](https://openairdocs.org/ntsb/MIA08CA072), Mar 4, 2008: Eurocopter France AS350B1 (N152TA), Linden, NJ, substantial damage. Probable cause: The pilot's improper preflight preparation and his failure to maintain control of the helicopter.
