Brief Description:	Plenum Cover Cracks
During oil change, at 285 hours, I found several small cracks in the plenum cover. I stop-drilled the cracks, and fabricated .032 inch thick 2024-T4 doublers, powder coated them, and riveted them in place. Additional cracks are likely to occur, and if I decide to rebuild the plenum, I likely will use .040 inch as the base material and incorporate similar doublers.
