I am working on a composite repair for the TR sleeve on an RB211-535E4 engine. The actual TR sleeves are made by Rohr. I am in need of a DWG for the TR sleeve.
The damaged area is located on the outer skin in the lower corner of the part at the slider fitting. The area has a graphite doubler...
I also posted this in the Composite section, but I think it is as or more relevant here.
