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 CHI03LA046](https://openairdocs.org/ntsb/CHI03LA046), Jan 5, 2003: Cessna 310R (N37221), Ada, MN, destroyed.
