The 182 (1957) and 182A (1958) were the only 182s to come out without cowl
flaps. This "feature" makes the oil temps run pretty warm, especially
climbing in the summer over high terrain. I've done an STC search and
haven't found anybody who has done the work on what is commonly called a
"summer lip" for the airplane cowl. There are summer lips for the 120, 140,
170, and 172, but none for the 182.

Has anybody here done a 337 installation that I could copy rather than
reinventing the wheel with the SAC FSDO? I'd really like to avoid the
hassle of doing the paperwork blizzard from scratch.

Hmm, my 182A was built in '56. G

If I remember there was a small lip along the lower, center edge of the
cowling. Is that what you're talking about?

I should be able to take a peek at it this weekend.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.
