it doesn't matter who you work for, under what part or what pilot certificate level you hold. the rules are all the same. 

Under the new regulation, third class medicals issued to pilots under age 40 became valid for a maximum of 60 months, up from 36 months. Pilots who are age 40 and older will still renew a third class medical every 24 months.

First class medical certificates are now valid for 12 months for pilots who had not reached age 40 at the time of their medical examinations. Pilots age 40 and over will continue to renew a first class medical every six months.

Under the new regulation, when the first class privileges expire after twelve months, the first class medical lapses to a third class medical. The regulation change does not affect the duration of second class medical certificates, so, for pilots under age 40, the first class and second class medical durations run concurrently for twelve months.
