PRIA Requirements for Part 91 Operators
Since Part 91 operators do not meet the definition of an air carrier, they are not required to request PRIA records when hiring a pilot.
However, certain records must be retained by Part 91 operators in case they receive a records request from an air carrier.
Within 30 days after receiving a PRIA request, the Part 91 operator must provide records pertaining to:
training, qualification, proficiency, or professional competency of the pilot;
any disciplinary action that was not subsequently overturned;
any release from employment or resignation, termination, or disqualification with respect to employment; and any FAA-mandated alcohol and drug testing program results.
In many cases, a Part 91 operator may not have any records on the pilot that would be pertinent to the PRIA request. In these situations, a simple letter to the requestor stating that no records are available satisfies the regulatory requirements.
