Mirror installation required?

Can anyone point me to a FAR or Advisory Circular that specifies a mirror is required? I just am curious if its a smart practice or an actual requirement for towing. I'm sure this has been covered before but the proof escapes my research.

Thanks

No FAR requirement. Mirrors are excellent practice. What you carry or mount inside is less likely to attract ramp-inspection attention. What would be more useful is for persons to post N-numbers of airplanes that have 337s for approved installations. Then folks with no mirrors can pursue having approvals for new installations.

In actuality, you don't want to discuss N-numbers with mirrors, unless you KNOW that there is an approved installation. My supposition is that there are a LOT of mirrors out there without an FAA-blessed installation.

There are a couple CAP Alaska machines that have strut-based approved exterior mirrors. I don't recall the link. That might be used as a reference to create a local field approval for other strut equipped towplanes.

All for exterior mirrors,

I think mirrors on each side of the Pawnee's cowl, being closer to the pilot, give a better view than strut mount mirrors. On my Husky, I have a wide mirror inside up high so it looks back out the top skylight. It cannot see below the horizontal stab, but it's okay for the high tow position and better than nothing.

I've heard of, but not used or seen, of tow planes using a rear view camera instead of mirrors.
