It would be possible for someone to remove them from the preamble by modifying the FDR file, but I have no evidence that anyone did this.
I have four FDR files from another source and they also have no AC ID or FLEET ID fields. Rob Balsamo asked me to share the other files, but my source has has denied permission since they were from a client and that client had not given permission for my source to share the files with me. My source shared the files with me so that I could help him decode them.
I think that the AC ID and FLEET ID fields never appear in the text preamble contrary to Dennis Cimino's claim that they always do.
