The public federal record on N503DK, 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 Kroesch Donald F, an individual, certificate issued August 22, 2024, expires August 31, 2031. No fractional interest recorded. [1]
The airworthiness certificate on file is dated February 22, 2022, 21 years after the 2001 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 CH20198-1705 for this model in the deregistered file. [2]
No other airframe has carried N503DK 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]
