The public federal record on N441MD, 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 Keystone Aerial Surveys INC, a corporation, certificate issued September 14, 2019, expires September 30, 2029. No fractional interest recorded. [1]
The airworthiness certificate on file is dated December 15, 1992, 13 years after the 1979 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 other airframe has carried N441MD 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]
