My original ATP was ATP-AMEL with Commercial priveleges -ASEL/Inst. It was originally issued in 1999. I have gotten a few types over the years which have driven several ATP card reissues. So last week I happen to read the back of my license and it states ATP-ASEL/AMEL with no mention of Commercial privileges. I'm thinking this is obviously an error as I have not taken an ATP checkride in any single-engine aircraft, at least not to my knowledge. My fault for not paying more attention over the years, but it appears I now have an extra rating which I did not earn.

Anybody else ever encounter this? Was it easy to correct? I have no idea which FSDO I went thru. Obviously, I'm concerned it might come up during an interview so I'd like to get some documentation rolling now to fix the issue.

Thanks-

KC
