## NTSB investigations (2)

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 LAX94LA241](https://openairdocs.org/ntsb/LAX94LA241), Jun 7, 1994: Hughes 369D (N4943T), Kaneohe, HI, substantial damage. Probable cause: the operator's and pilot's failure to ensure that the cargo net containing empty paper bags was sufficiently ballasted to prevent it from flying up into the tail rotor.
