Corroded Engine Mount Frame
In a thread titled "Ceramic Coated Exhaust", SkyKing pondered: "I wonder how many others that have the P-models have had or are having surface erosion of the long upward tilting angle piece on the left side of their rear engine mount that sits next to the left-side exhaust and turbo?"
I took my digital camera out to my plane to check. Sure enough, the frame is showing surface corrosion. The picture is attached. My shop (who is new to this plane), said that is something they would routinely touch up at annual.
Are others finding this to be a chronic problem? Does it need a heat shield, or will high temp paint handle the job?
For those with sharp eyes, I placed a quarter (25 cent coin) between the vertical exhaust and frame at the far left in this picture. This was intended to show the approximate clearance. I’d estimate the clearance is about 2/3rds the height of a quarter.
