Thanks Roger,
Several of the engine mounts have been replaced over the years. In fact I have one on the front that will be replaced this annual. The cracks keep occurring on the lower "ring" portion of the cowling underneath the prop spinner. It has been repaired several times but the underlying issue seems to be that the entire assembly cannot be reassembled after the repair without having that piece under some stress. The repairs last about 100 hours and then the cracks reappear. The entire cowling has many patches on it so my IA's thought is to attempt to just replace the entire two assemblies hopefully from the same airplane.
We'll see!
Ed
