Doc,
My O2 mask wearing days are over. If I have to get a mask to fly my Yak, it's
gone. [Wink]
I only need heat in the dead of winter while cruising at altitude and the standard
-52 system works just fine for that. I don't want to engineer a whole new
system to replace one that works fine.
However, like many other systems in our planes it must be inspected to insure it
is working properly...lest it bite you. And inspecting this section of exhaust
can only be done by removing it and looking closely for any cracks inside
the inner most pipe.
I suspect my -52 isn't the only one that has not had such an inspection done in
a while...if ever. I also suspect there are other -52's out there right now
with cracked pipes that are pumping CO into the cockpit. What are the odds that
only one -52 in the world (mine) had an exhaust crack in that section of pipe?
Fly safe,
Steve
