## 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 CHI03LA209](https://openairdocs.org/ntsb/CHI03LA209), Aug 22, 2003: Young Cozy MkIV (N96PJ), Quincy, IL, substantial damage. Probable cause: The pilot's improper flare.
- [NTSB FTW97LA009](https://openairdocs.org/ntsb/FTW97LA009), Oct 4, 1996: Young Cozy MK IV (N96PJ), Pueblo, CO, substantial damage. Probable cause: the pilot/builder's improper design change which resulted in a loss of control following an intentional stall. A factor was an erroneous weight-and-balance calculation.

## FAA accident and incident reports (5)
