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 NYC66F0099](https://openairdocs.org/ntsb/NYC66F0099), Jul 19, 1965: Lockheed 10A (N38PB), East Boston, MA, substantial damage ## FAA accident and incident reports None matched to N38PB. ## Reports on N38PB not matched to an aircraft (1) They name N38PB, but no registry record covers the date, the aircraft registered then was built later, or the report describes another aircraft. - [Incident 19810705060649I](https://openairdocs.org/incident/19810705060649I), Jul 5, 1981: Doug DC3 (N38PB), Boston, MA, Minor damage.
