elongation of the bolts or bolt holes. If ANY bolt-hole elongation is
more than .010” inch then the propeller must be returned to CATTO
for a closer inspection and the attaching bolts must be replaced.
e.
Inspect the spinner rear bulkhead and engine flange for fretting. If the
fretting is severe and cannot be dressed out with emery cloth and re-
anodized (for aluminum parts only) then the parts must be replaced. Clean
the flange faces for re-installation.
