Pressurization and Oxygen Systems

[Mark Hislop]

Alan:

Along with all of the things Kevin and Bob mentioned, also check the avionics inspection panels just in front of the wind shield. They are also part of the pressure vessel. The gaskets get old and worn. Worse yet, people sometimes use silicone to try to seal them, and they get torn when you remove the panels. Also check to see that the small cups underneath each of the dzus fasteners are in place (they probably are missing). These are used to seal all of the fastener holes.
