A PRELIMINARY STEPS

NOTE: This MPC is completed by a Depot repair activity or requires Depot level assistance.

1. Contact USCG regional dive lockers for first right of source IAW COMDTINST 3150.1 (series) before con-tacting contracted dive services.

WARNING

ENSURE EQUIPMENT IS PROPERLY TAGGED OUT. FAILURE

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 pre-clean 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. Verify propeller pitch position.

a. Place the speed/pitch control mode SELECTOR switch in the “EMERGENCY MANUAL” position.

b. Pitch the propeller manually to the “ZERO PITCH” position as indicated on the scale located on the

Oil Distribution (OD) box.

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