Bob,

My window cracked at about 250 hours and I had a fast build door as= well.=20 My kit is 506 and was purchased in 2000. I fly consistently at FL250 and= a few=20 times at FL280. When I repaired it I put a lot more carbon over the stiffe= ner=20 section. The crack was in the upper rear corner and went around the corner= right=20 against the carbon outer shell. It was very difficult to see as was yours= and I=20 noticed it when cleaning one day. Mine cracked at FL250 and sounded like= a=20 baseball hit the door somewhere.

One possible theory is could be overpressure on the door seal in addi= tion=20 to the cabin pressure. I noticed when testing the pressurization on= the=20 ground that the door is pushed outward by the door seal.

Another friend of mine blew this window out of the plane at FL210 nea= r=20 Bend, OR. His was not a fast build door. Luckily his wife was not in the= plane=20 with him. She would not enjoy flying quite as much any more.

I wonder if there are others out there that have had this problem.
