Here's the "real" regulation from 121.383

engaged in operations under this part if that person has reached his
60th birthday.

Note that there is no distinction between PIC and SIC and Robert, there
are no part 121 PICs with only a Class 2 Medical Certificate, but there
are SICs with only a Second Class. Both must cease Part 121 operations
upon reaching their 60 (65) birthday.

Thanks Bob, we can always count on you to look this stuff up. I think
the reason that there is no distinction between PIC and SIC is because
of the old sole manipulator thing. The SIC is sole manipulator on
every other leg . As I understand it, the FO will have to be under 60
when the new rule comes out.
