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 MIA08LA185](https://openairdocs.org/ntsb/MIA08LA185), Sep 6, 2008: Bellanca 17-30A (N9792E), Sparta, TN, substantial damage. Probable cause: Failure of the nose landing gear mount during a normal landing due to an improper weld. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
