Is my Reiff sump heater installation
illegal without the A&P signoff?

The above text says that you don't need an IA to prepare a 337.
You need an log book entry on any maintenance or alteration.
Unless it's covered in the preventive maintenance exceptions
that has to be an A&P.

Thanks Ron. I went back to my partner and he looked through the
manual that came with our preheater and buried somewhere in there is
text that states and A&P is not required to do the installation, just
the signoff.

Since the bird went into the shop this afternoon for a possible
rebuilt carb., we will have the proper notation made.

Appreciate setting me straight.
