## 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 DEN00LA094](https://openairdocs.org/ntsb/DEN00LA094), May 21, 2000: Cessna T210M (N66DF), Laramie, WY, substantial damage. Probable cause: The pilot-in-command's failure to confirm, the landing gear was down and locked. Factors were the check pilot's failure to confirm the landing gear was down and locked, and the sun glare.

## FAA accident and incident reports (1)

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.

- [Accident 20000521012239A](https://openairdocs.org/incident/20000521012239A), May 21, 2000: Cessna T210M (N66DF), Laramie, WY, No damage. (-23) After completion of airwork manuevers during his commercial asel examination 2100ZZ, the applicant proceeded to land. During landing the gear collapsed.

## Service difficulty reports

None filed for this aircraft. Matched to this aircraft by N-number and event date, checked against the reported serial number, make and model.

## STCs that may be installed (OpenAirDocs) (479, first 50)
