TO COMPLY MAY RESULT IN SERIOUS PERSONAL INJURY

OR DEATH.

2. Complete Equipment Lockout/Tags-Plus Process IAW COMDTINST 9077.1 (series).

B INSPECT UNDERWATER HULL AND APPENDAGES

1. Inspect the entire underwater hull and all appendages.

a. Conduct a preclean biofouling inspection, (Refer to Form 1).

b. Conduct diver hull inspection, (Refer to Form 2).

(1) Complete any additional inspection forms to document underwater component damage or find-ings, (Refer to Form 3, Form 4, and Form 5).

C CHECK HUB AND PROPELLER PITCH

1. Check that the securing rods welded on the propeller blade bolts are connected and in good condition, (Refer to Figure 1).

2. Energize one of the Controllable Pitch Propeller (CPP) electric pumps IAW posted operating procedures.

3. Check pitch positions.

a. Verify propeller is in the “PITCH” position.

b. Turn the speed/pitch control mode SELECTOR switch in the “EMERGENCY MANUAL” position.

c. Pitch the propeller manually to the “ZERO PITCH” position indicated on the scale located on the Oil

(1) Verify with the diver that the corresponding marks are aligned at the hub and blade palm.

g. Check the propeller hub for signs of external oil leaks.

h. Pitch the propeller manually back to the “ZERO PITCH” position.

i. Place speed/pitch control mode SELECTOR switch to the normal operating position.

j. Secure the electric CPP pump IAW posted operating procedures.

4. Repeat Steps 1 C 1. through 1 C 3.j. for the remaining propeller hub.

5. Reconnect necessary Operating Components and Remove Lockout/Tags-plus Material and Hardware IAW COMDTINST 9077.1 (series).
