Hello team,

I live in Oregon and the temps are starting to fall to freezing levels. I have a 63 Piper Cherokee and it is advised to install the winterization plate when ambient temperatures drop below 50 degrees.

Was wondering if any of you have the same situation. I have the plate but to be honest have had multiple A&Ps look at it and are perplexed as to how it would be installed and it’s purpose. None of the Cessna's use them nor any of the Pipers they have worked on.

I have looked on YouTube and have seen videos of people in Alaska using metal tape to cover the air inlet.

I am assuming the cold air flowing through the intake with the higher temps of the oil flowing through it may cause a fracture but am obviously at a loss of knowing the principle behind the design especially since other aircraft with the exact same engine don’t ever use them.

The airplane is 60 years years old and I haven’t spent much time flying in freezing temperature's. If anyone has any feedback it would be greatly appreciated.

Kind regards…
