Hi X
Thanks for the 3 posts
ABDA4B decodes to N863DD not assigned by FAA, this aircraft is now registered N860DD since June last year, presumably miscoding old ID
3CFAF9 D-CWIR is now N288VP, Cessna 525B CitationJet CJ3, c/n 525B-0288, Eclipse 5 Coal Sales and is allocated A2ED9C. Registered 26/12 and is in the d/b under its allocated A2ED9C. Again presumably using its old ID.
Who are TYU? I don't recognise the code.
