We just completed our first engine starts and taxi test. The next day I noticed a few areas of small cracks or crazing lines on the aft window. The crazing lines are on both side of the aft window in the same location (where the lexan has the most radius bend). I will try to post some photos here.
They appear to be from the stress of the bend of the lexan. They do not appear to start at the screw holes or the aft edge of the lexan glass. If you run your finger nail across the outside, you can feel it line, but nothing on the inside.
I know there was some comments about not using black electrical tape for masking, which we did not. We used painters masking tape when it was painted. We have not spilled or used any gas or solvents on the glass. Anyone else have any problems here??? Vans said fly it and keep an eye on it, they dont know what is causing it.
