NOTE : Quoted from the "Maintenance Manual for use by the Maintenance and Repair Shops" —Airframe Manual — DGAC — SFACT — N° AC 65-15.
1) With the rim / disk locking device being engaged in the deep slot, rotate the disk setting device so as to lock the disk onto the rim.
2) Put the control surface to neutral position. Position the clinometer on the control surface and rotate the rim setting device so as to bring the bubble of the center level between the marks (the rim should be unlocked from the frame).
3) Lock the ring on the frame using the ring lock on the frame.
4) Bring the control surface to its maximum travel limit.
5) Unlock the disk from the rim using the rim / disk locking device.

NON-DESTRUCTIVE INSPECTION
DESCRIPTION AND OPERATION
1. GENERAL
The purpose of non—destructive inspection consists in detecting structural defects without altering the area or adjacent equipment.
It mainly consists in an inspection for cracks and corrosion. The main methods used are :
— visual inspection,
— penetrant inspection as a complement to the visual inspection.
2. DESCRIPTION
A. Visual inspection
This method consists in visually inspecting suspicious parts. This requires a thorough cleaning of the incriminated area.
Visual inspection is the oldest and most common form of non—destructive inspection. It provides a means of detecting and examining a wide variety of material surface discontinuities such as cracks, corrosion, contamination, surface finish, weld joints, solder connections and adhesive disbonds.
This method can be used by any person but requires, nevertheless, the knowledge, skills and abilities to understand where flaws are likely to occur in the aircraft.
The use of optical aids for visual inspection is beneficial and recommended.
