Had a line check the other day, the overall outcome was a pass. At the start of it, when the LCA was reviewing certs and docs, it was discovered that I had missed an update on one of my manuels which he decided was a no fly, he allowed me to update my manual since I had the revsision tucked away and I had forgetten about and all is updated and I flew the flight as scheduled. While he concluded the line check was a pass, this revsision update was considered a "training event", so I'm a little confused, is this something to disclose, gonna be on my PRIA? Just unsure about how to go about it with a future employer.
