## 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 SEA03LA125](https://openairdocs.org/ntsb/SEA03LA125), Jul 4, 2003: Sikorsky UH-19D (N37799), La Grande, OR, destroyed. Probable cause: The cross threading and separation of the clutch assembly while maneuvering which resulted in a loss of engine power followed by a hard landing. An inadequate maintenance overhaul was a factor.
