## NTSB investigations (4)

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 DCA25WA121](https://openairdocs.org/ntsb/DCA25WA121), Nov 11, 2024: Agusta A109S (N449C), Dublin, Ireland, incident, no damage
- [NTSB WPR21LA039](https://openairdocs.org/ntsb/WPR21LA039), Nov 6, 2020: Agusta A109 (N109EX), Los Angeles, CA, substantial damage. Probable cause: The loss of tail rotor control due to the separation of the tail rotor duplex bearing ring nut from the thrust sleeve, which resulted in the loss of helicopter control.
- [NTSB CEN19FA185](https://openairdocs.org/ntsb/CEN19FA185), Jun 28, 2019: Agusta A109 (N11NM), Brainerd, MN, substantial damage, 2 fatal. Probable cause: The pilot's spatial disorientation during an instrument approach in dark night instrument meteorological conditions, which resulted in a loss of control and subsequent impact with terrain.
- [NTSB CEN16FA372](https://openairdocs.org/ntsb/CEN16FA372), Sep 17, 2016: Agusta A109 (N91NM), Alexandria, MN, destroyed. Probable cause: The pilot's excessive cyclic input during a missed approach maneuver in night instrument meteorological conditions, which resulted in a loss of control and spiraling descent into terrain.
