After years of reading about UV degradation, exposure issues with covering materials; and seeing UV tests galore I got to thinking to myself. "how many hours of sunlight exposure will most Piets actually experience?" I'm sure they exist, but I don't know of a single Piet that doesn't reside full-time in a hangar. I then did some math and calculated the number of hours a year she's actually outside, and what percentage of those days are full sun, and what percentage of full-sun days eve/morning flights with a low sun angle to arrive at some numbers. I'm certainly not suggesting UV protection is unimportant. I'm just wondering if we are possibly overdoing it sometimes considering the real world application on this airplane. Do some figuring, I'll bet you'll be surprised. I was. I think I concluded that I could fly with untreated ceconite for like two decades.

I have an engine just about apart, and a spare for parts. Good to know that other engines/parts are out there. Thanks for the information. -------- John Read this topic online here: http://forums.matronics.com/viewtopic.php?p=429582#429582 ________________________________ Message 5 _____________________________________ Time: 06:44:24 PM PST US Subject: Pietenpol-List: Re: 12 rebuildable Corvair engines 20 miles from B-head From: "fastj22" I found a guy in Colorado that has at least 6 cores and set me up with what I think is a great build.
