To answer your question, tail shaft, and tail gearbox covers are normally screwed in place, and it would not be practical for a pilot to remove these on a walk round. My thoughts on a pilots walk round, are just to see if someone has left a tool on the aircraft, or a panel fastener not done up, otherwise where would you stop. There are many controls etc covered up that a pilot cannot see.
A double tail rotor, that sounds like a complicated nightmare.
