There are two versions:

FAA Version: Goes to the FAA, and they provide info back to the carrier regarding your medical, certs, ratings, and violations. IIRC it does NOT actually return info on failed checkrides, but this could still be acquired by a FOI request I think.

Air Carrier Version: Goes to previous employers. The CFRs specify exactly what info has to be provided...basically your training performance and disciplinary actions relatred to flying duties. I think disciplinary action related to telling your CP to go f### himself is not supposed to be reported via PRIA, but landing in the TDZ at the DEPARTURE end of the RWY and subsequently going into the grass would be reported.
