FAN AND BOOSTER
(ALL) :
Rigid probe No 2 (yellow), installed on a long right angle
adapter, can be used to reach the front of the splitter
fairing area in order to inspect the booster.
From this position the following are visible:
- Stator vane stage 1
- Rotor stage 2 leading edge through stator stage 1.
Borescope equipment is not needed to inspect stator
stage 1 and stage 2 rotor blades if the fan blades are
removed (when fan blades have to be relubricated, for
example).
