Two words... Preventative maintenance.

Which can be done by the owner, not a renter.

It can also be done by the renter, as long as the renter only works on the
airplane being operated by him (which is the scenario in question here).

If the airplane is used for Part 135 service, the renter is technically not
allowed to. However, if I were that renter, and I couldn't find an approved
mechanic to do the work, I would still do it myself and let the FBO know
that some non-Part 135 service had been performed on the airplane.

Heck, for that matter, I'd let the FBO know what I'd done regardless and
make them pay for the bulb.
