MAIN SPAR. Main Spar Seal


The increased pressure inside the engine compartment and the decreased pressure between the main spar and the wing spar leads to the flow of hot air from the engine compartment into that space. According to the factory, this may cause delamination and compromise their structural integrity. The factory recommends sealing with silicone. I decided to block this flow of air by sealing the space with a silicone-based seal that I glued in place with high temperature RTV.
