## NTSB investigations (1)

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 WPR10LA034](https://openairdocs.org/ntsb/WPR10LA034), Oct 21, 2009: Aero Commander 690 (N690TR), Cedar City, UT, substantial damage. Probable cause: The failure of the landing gear accumulator/regulator and the installation of the improper priority valve, which precluded the landing gear from extending and locking into place.

## FAA accident and incident reports (2)

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
