At about 150 hours of flight time, 125 Tach. After returning from formation flying found a couple of cracked pieces of baffle off the #1 and #4 cylinders. The metal is .032" 2024. I removed the broken pieces and will see if there's much effect on CHT's. These parts were cut per plans. -Update....I think the broken baffles should have been on the outside, not pinched by the screw. I made new baffles but this time made a lip so the edge clears the screw where the crack occurred and stiffens the part. A bead of RTV was applied to reduce fretting.

| The new baffle's edge was folded upward to clear the screw and stiffen where it previously broke. |

| The right cylinder baffle clears the 1/4" screw. A bead of RTV should help reduce fretting. |
