(ALL) :
Inspection with rigid probe.
Inspect the HPT nozzles through ports S13 and S15.
Use probe No 1 (black, high magnication) to inspect the
nozzle segments. The high intensity light source is used
to accurately inspect the nozzles.
Insert the probe into the ports and inspect the concave
sides and leading edges of the nozzle segments.
Note: If defects are found, a complete inspection of
the combustion chamber and the nozzles has to be
performed.
