## 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 DCA25FA071](https://openairdocs.org/ntsb/DCA25FA071), Dec 26, 2024: Boeing 737 (N958AK), Henderson, NV, no damage, investigation ongoing
- [NTSB DCA25LA025](https://openairdocs.org/ntsb/DCA25LA025), Oct 24, 2024: Boeing 737-9 (N27515), Houston, TX, substantial damage. Probable cause: Brake application before all three landing gears were on the ground, which caused the failure of the right main landing gear tires and resulted in tire fragments impacting the fuselage.
- [NTSB DCA23LA445](https://openairdocs.org/ntsb/DCA23LA445), Sep 7, 2023: Boeing 737-9 (N37531), Hebron, KY, no damage. Probable cause: An inadvertent encounter with convectively induced turbulence (CIT) during descent.
