FLIGHT CONTROL SHEAR RIVETS - MAINTENANCE PRACTICES
1. Shear Rivets
A. Shear rivets provide a means by which normal operation of essential flight systems can be maintained in the event of failure or jamming of related or interconnected secondary systems. Each shear rivet location is marked by a placard or marker stating Shear Joint and the quantity and type of shear fastener used. The accompanying chart contains a list of all shear joints used in the flight control systems along with part numbers and references to maintenance manual sections where maintenance procedures can be found.

FLIGHT CONTROLS SURFACE - INSPECTION/CHECK
1. General
A. The following section defines the allowable limits for trailing edge movement of flight control surfaces with the airplane on the ground.
B. Measurement is to be made with control surface in approximate faired position at surface inboard trailing edge unless otherwise noted.
C. Movement within limits is acceptable provided that the wear at the mechanical parts is distributed evenly throughout the points in the system. However, if inspection and checking reveals that wear is noticeably present at a local area, then that portion of the system should be restored to serviceability.
2. Equipment and Materials
A. Dial Indicator - Accurate to 0.001 inch
B. Spring Force Scale, Push Type - Capable of 33 ±0.2 pounds
C. Mounting Device to hold the dial indicator
3. Ailerons and Aileron Tabs (Fig. 601)
A. Do a check of the play of one aileron with no movement of the opposite aileron or the control wheel:
WARNING: KEEP PERSONS AND EQUIPMENT AWAY FROM ALL CONTROL SURFACES AND THE LANDING GEAR WHEN HYDRAULIC POWER IS SUPPLIED. THE AILERONS, ELEVATORS, RUDDER, FLAPS, SLATS, SPOILERS, STABILIZER, LANDING GEAR AND THRUST REVERSERS CAN MOVE QUICKLY WHEN SUPPLIED WITH POWER BY THE HYDRAULIC SYSTEMS. INJURIES TO PERSONS OR DAMAGE TO EQUIPMENT CAN OCCUR WHEN HYDRAULIC POWER IS SUPPLIED.
(1)
Pressurize the aileron trim control hydraulic systems A and B (Ref 27-11-0, MP).
(2)
Make sure the control wheel is centered.
(3)
Attach a mounting device to the top wing structure (outboard of the aileron) and do these steps:
(a)
Attach the dial indicator so you can take measurements from the outboard corner of the aileron trailing edge.
