Pilots station SPAD inspections:

TB 1-1520-238-20-66

(26) Reconnect the DASE Computer connectors (P682, P686 & P688).

Reset (close) the

BUCS circuit breaker in the Pilots station (center C/B Panel).

CAUTION

Do not attempt to move the pilots controls with the CPG'S SPAD shear

pins removed. Manual movement of the Pilots controls may break/ shear

the SPAD shear pins in that station. Ensure no BUCS locks (pins) are

installed. The pilots station controls will move (powered) during the

following procedures.

(27) Verify that the aircraft is cleared for flight control movement. Apply primary hydraulic and

electrical power. Verify that the "BUCS ON" a caution/warning light is "ON."

(28) Move the CPG's Cyclic Stick in one control axis at a time (Lateral [side to side],

Longitudinal fore & aft]). Visually confirm the movement of the Main Rotor Head (swashplate) in response to

the cyclic control inputs. Continue to verify individually, the control responses for the Collective and Directional

(pedal) controls. If the controls do not respond correctly, troubleshoot I/A/W reference e., apply corrective

action and retest.

(29) If the controls responded properly, move (depress) the left directional control pedal

forward,

and move the cyclic stick to the full aft position prior to shutting down power; this orients; the

pilot station

SPAD's for inspection purposes. Remove hydraulic and electrical power. Proceed to

CAUTION

The Mechanical Cam contained in each SPAD must be repositioned to the

center or armed position (switch detent aligned with indicator); and held

momentarily to install the shear pin. Failure to reset/arm the cam renders

the SPAD inoperative.

NOTE

Ensure that the "shear point" (notch) in the shear pin is properly located in each

SPAD Assembly (visible between the moveable arms).

(30) Install the shear pins in each SPAD Assembly in the CPGs Station. Refer to tasks 11.43

for the collective SPAD; 11.46 for the Directional SPAD; 11.83 for the Lateral SPAD; and 11.82 for the

Longitudinal SPAD.

(31) Re- connect plug P118/J118 adjacent to CPG's Directional SPAD (panel B60).

(32) Installation of the access panels for the CPG Station SPAD's may be deferred until

completion of the Pilots Station SPAD's.

c. Pilots station SPAD inspections:

NOTE

Observe all task preconditions, notes, cautions and warnings or damage to the

personnel or the aircraft may result. Retain all fastening hardware for

reinstallation. Inspect removed shear pins for straightness (bent/bowed) and

deep material scratches - none allowed. Minor surface scratches along the pin

shank are permitted, as are tooling marks and gouges, resulting from the

removal process on the ends of the pin (head/taper).

(1) Remove the Pilots Foot Guard/Shield (7-311180008), I/A/W task 2.189.
