The public federal record on N602WC, 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 Blair Helicopter Service INC, a corporation, certificate issued March 2, 2018, expires March 31, 2028. No fractional interest recorded. [1]
The airworthiness certificate on file is dated February 18, 2019, 49 years after the 1970 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 70-15633 for this model in the deregistered file. [2]
No other airframe has carried N602WC according to the deregistered file. [2]
No bills of sale, loans or releases have reached the registry in recent weeks. The index covers only recent filings; older liens are in the records file. [3]

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.
