Bottom line

A person may serve as a required pilot flight crewmember only if that person holds the appropriate medical certificate issued under part 67, or other documentation acceptable to the FAA, in physical possession or readily accessible in the aircraft. A pilot certificate, including a student pilot certificate issued after April 1, 2016, issued under part 61 is issued without an expiration date.
