The public federal record on N669KB, read the way a buyer, lender or insurer reads it: FAA registration, prior tail numbers keyed on the serial number, reuse of the tail number, recent registry filings, and the NTSB accident record under this and every earlier registration.
Valid registration to Sof Air INC, a corporation, certificate issued May 1, 2017, expires May 31, 2027. No fractional interest recorded. [1]
The airworthiness certificate on file is dated July 27, 2006, 40 years after the 1966 manufacture year. A re-issued certificate commonly follows export and re-import, a rebuild, or a return to the register after cancellation. The cause is documented in the FAA aircraft records file, which the full report obtains. [1]
No earlier tail number is recorded against serial 66-1229 for this model in the deregistered file. [2]
No other airframe has carried N669KB according to the deregistered file. [2]
1 document received recently: Bill of sale (evidence of ownership) (September 25, 2026). [3]
No NTSB investigation records located under N669KB. CLEAR means the query ran and returned nothing, not that nothing ever happened. [4]
These live in the FAA aircraft records file (every document ever filed against the aircraft) and, for larger aircraft, the International Registry. Part of the full report.
AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
