Missing tail numbers for American/Envoy

We are experiencing a situation where the registration field is null for a few American and Envoy flights. What we have found is that American has renamed some of their tail numbers, while the FAA registry shows these tails number changes as pending, they are apparently in use. This is more of an informational post to anyone who is also experiencing this issue.

A example is flight 5/7/2023 ENY4146 DFW 1533 AMA 1552

The aircraft type is still being reported.

Thanks,
Jim

Is this a problem with the data you’re receiving from AeroAPI? If so, could you share the request you’re performing (ideally with a flight ID) and the response payload?

Yes I used the Aero API. I recreated on the website using:
ident: ENY4146
start: 2023-05-07
end: 2023-05-08

The flight id is ENY4146-1683315684-airline-573p

Here is the response:

Thanks for your report and additional information. The prior owner of the registration had blocked it with the FAA so it was being suppressed from responses. We’ve overridden its status for now, and you should begin seeing it in responses in the new few hours.
