N451WS — Robinson Helicopter R44 II
Public record from the FAA Aircraft Registry and the NTSB Aviation Accident Database. Registered owners are not named on this page.
This airframe has a record under a different tail number
The manufacturer serial number carried by N451WS also appears on 1 NTSB record filed under N510KJ. A search on N451WS alone — including the FAA's own registry — does not show it, because the tail number changed and the serial number did not.
Serial matches are only accepted when the manufacturer on the NTSB record agrees with the manufacturer on the FAA registration.

A record on this list is a report that an event occurred. It is not a statement about the aircraft's present condition — an airframe can be repaired to standard and returned to service, and the NTSB record stays on file either way. What the repair actually involved is in the logbooks and the FAA document file.
