## 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 ERA22LA179](https://openairdocs.org/ntsb/ERA22LA179), Apr 4, 2022: Mooney M20M (N41XL), Manville, NJ, substantial damage. Probable cause: The pilot’s delayed go-around decision following an encounter with a tailwind during landing, which resulted in an inability to climb and subsequent impact with trees.
- [NTSB CEN09CA414](https://openairdocs.org/ntsb/CEN09CA414), Jul 2, 2009: Mooney M20 (N270SD), Steamboat Springs, CO, substantial damage. Probable cause: The pilot's improper pitch control during the go-around, which resulted in an aerodynamic stall.
