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 DCA18CA074](https://openairdocs.org/ntsb/DCA18CA074), Nov 19, 2017: Boeing 737 7H4 (N740SW), Los Angeles, CA, no damage. Probable cause: The provisioning agent's lack of situational awareness while stepping from the airplane to the provisioning van. Contributing to the accident was the provisioning vans failed switch. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
