I have the stock Cessna clock that has stopped working. Fuse and wiring are good, clock is inop. Questions, after reading 91.213(d)(3)(ii) -Doed the fuse need to be removed? It’s already inop, but not really deactivated, so thinking I would need to. -Does a mechanic need to placard & log it as inop? I think I can do so, but thinking about what a pilot can/can’t do under maintenance regs. In order to prevent POA arguments about needing a clock, just assume I have another one installed and working that meets the intent of the FARs (which I do).
