CAUTION
Due to the high stresses to which the

careful maintenance is vitally
important,
particularly
on the leading edge of each

A11 nicks and scratches must be
repaired before the airplane

of stress
which can exceed the strength

In addition

method for detecting
craeks in blades is as follows:
Clean the blade carefully
thoroughly,
using a clean

2.
Prepare ? solution
of SWonon-toxic,
non-corrosive

and 50% kerosene.
3.
Completely immerse the blade in the solution
and allow it to
remain f or a minimum of thirty
minutes.
Af ter this period,
remove the blade from the bath and allow the excess fluid
to
drain.
Spray the blade with carbon tetrachloride
to completely
remove the remaining solution.
A11ow the blade to stand for
fifteen
minutes so that the solution will bleed out of anv
cracks present.
4.
Carefully
inspeet the entire blade under a near-ultraviolet
light
source.
The inspection
must be conducted in a darkened booth or
room.
Solution
bleeding from a surface crack will
show up under
the light
as a bright
