## NTSB investigations (3)

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 ENG07IA034](https://openairdocs.org/ntsb/ENG07IA034), Aug 12, 2007: Learjet (N244F), Salt Lake City, UT, incident, no damage. Probable cause: The fatigue fracture of the fan blade due to the blade vendor's improper setup of the forging dies, which resulted in fan blades with airfoils that were below the minimum thickness in the highest…
