Inspect the cylinder walls for signs of vertical
scuffing pattern (refer to the reference
pictures as shown on the right for scuffing
examples).
If no scuffing is found, then inspection is

a picture of the borescope display of each
identified cylinder wall surface if scuffing
is found.
Once completed, upload the images using
the STUI Camera “Select a picture in
Gallery” function.
In addition, the following 2 items must
be included for PA approval process.
