## 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 WPR26LA006](https://openairdocs.org/ntsb/WPR26LA006), Oct 2, 2025: Siai-Marchetti SM 1019 (N3172U), Richland, WA, substantial damage, investigation ongoing
- [NTSB GAA19CA528](https://openairdocs.org/ntsb/GAA19CA528), Sep 7, 2019: Siai-Marchetti SM 1019 (N16XC), Lakeport, CA, substantial damage. Probable cause: The pilot's exceedance of the airplane's critical angle of attack during takeoff in gusting, variable wind conditions, which resulted in a loss of airplane control and subsequent impact with water.
- [NTSB ERA09CA220](https://openairdocs.org/ntsb/ERA09CA220), Mar 29, 2009: SIAI Marchetti SM-1019B (N273LH), Dade City, FL, substantial damage. Probable cause: The pilot's failure to maintain directional control during initial climb.

## FAA accident and incident reports (4)
