## 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 WPR23LA278](https://openairdocs.org/ntsb/WPR23LA278), Jul 19, 2023: Aerospatiale AS-355E Twin Star (N102UM), Farmington, UT, substantial damage. Probable cause: The premature failure of one of the No. 2 engine compressor bleed valve, which resulted in a partial loss of power to that engine.
