Can a crewmember deadhead with less than the eight hours of required rest if they are not going to perform any 121 duties that day?

here is the scenario,

crewmember works from about 4pm to 10:15pm. they are scheduled to dead head out the next morning with a show time of 5:30am. they will not be performing any flight duties but just deadheading.

is that legal?
 
yes by the regs. You are not performing duties under this part. In can not be counted as rest or duty free. Now a union contract might address something different
 
Yup, legal, however if you were going to have any duty (stop laughing) following the deadhead, you would need at least 8 hours of rest from the block in time of your DH flight.

Yes.

Here is a simple way to apply part 121.471(a)(4) (and the infamous Whitlow Letter):

1. While sitting in your left/right flight deck duty seat expecting to fly as a required crewmember determine your expected takeoff time. Add the scheduled flight time to block in, plus fifteen minutes for post flight (or what ever your company allows for post flight duty). Example:

Proposed t/o time - 1800
Scheduled flight - 0200
Taxi time - 0005
Block In - 2005
Off Duty - 2020


2. Look back to the previous day at 20:20.

3. Look forward from that time (previous day at 20:20) to now and find at least eight hours consecutive rest (at least nine hours if 121.471(b)(3) applies). You are good to go. If you can't find at least eight hours consecutive rest (again nine hours if 121.471(b)(3) applies), then you cannot fly the trip as a required crewmember.

All of the required rest duty limits for airline pilots only apply to accepting duty as a required crew member. There are no regulations for accepting deadhead assignments.
