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 FTW99LA068](https://openairdocs.org/ntsb/FTW99LA068), Jan 21, 1999: Waco YMF-5 (N19Y), Edmond, OK, substantial damage. Probable cause: The pilot's failure to attain the proper touchdown point due to excessive airspeed and his failure to abort the landing. Factors were the pilot's excessive braking and the short, grass runway. From the FAA Accident/Incident Data System.
