Skymaster Arctic Circle Ditching.

[hharney]

In the POH of my 1968 Super Skymaster (lots of emphasis on the SUPER) Section VII on Optional Systems contains "Cold Weather Equipment" and says:

WINTERIZATION KIT.
"For continuous operation in temperatures consistently below 20 degrees F, the Cessna winterization kit, available from your Cessna Dealer, should be installed to improve engine operation. The kit consists of two baffles for the front engine, one baffle for the rear engine, and crankcase breather insulation for both engines. Once installed, the crankcase breather insulation is approved for permanent use in both cold and hot weather."

Attached is a photo of the front baffles but I have never seen the rear engine baffle. The rear engine baffle is attached to the lower outside ring below the prop on the exit end of the airflow. This statement is pretty standard in most all the Cessna piston Pilot handbooks except for the Turbo models. Maybe the Turbo models generate enough heat and do not require this?
