Thanks for the detailed response, Denny. Good looking
Apache, by the way. I sent an inquiry to C&D and got
a prompt response this morning. Guess it is time to do some
troubleshooting on my end.

As Jay commented, Fat Albert is a 1957 Apache - fat and spoiled...

The Aztec I referred to is a D model, that came from a sheriff's
auction out of Texas... It was a drug seizure plane that occurred in a
hail of gunfire, so it was named, The Blue Shooter... It's heater
(Janitrol as I remember) worked well... So well, that on one dark and
steely cold morning, flying from Michigan to Florida in IFR conditions,
it kept overheating the brand new S-TEC 50 autopilot causing it to
silently and sneakily go off line at the most inconvenient moments...
The controllers at Greenville, South Carolina were convinced I was
snorting something... The Blue Shooter is currently hauling bank
checks across the North Sea, 6 nights a week...

Fat Albert's old Southwind worked, but did not handle bitter cold
adequately... The difference with this new C&D heater is night and
day... C&D has a PMA for the heater so no paperwork other than the
A&P's entry in the log is required... There was a bit of work even
though it is roughly the same size and clamped right into the ductwork,
the various parts are not in the same location around the can... One
blower was mounted on a shelf above it... The most work was for the new
switch and wiring harness... The old wiring was asbestos and cloth
cover, still serviceable, but not pretty or desireable, and the C&D
warranty requires the new switch with teflon wiring... At this point I
am happy as a clam in mud, with it... We will see how it fares over the
next few years... An interesting point is that the combustion air, fan
motor has a ram air flow switch which not only turns off the
electricity to the blower motor but also raises the brushes off the
commutator so they don't wear as the fan is rotated by the ram air...
They claim a 4,000 hour life rating on the combustion air, fan motor...

The annual is just completing, I will post a blow by blow on that in a
few days... Mucho $$ this year that Jay can relate to...
