- The joint plate at RIB 22.
B. Detailed Inspection of Outer Wing, Rear-Spar Aft Face, between RIB 11 and RIB 27, including Joint Plate at RIB 22
(1) Examine the applicable inspection area. Make sure that:
Subtask 57-21-00-916-052-A (1) Examine the applicable inspection area. Make sure that:
- There is no corrosion
- There are no cracks or damage
- There are no fuel or hydraulic leaks

5. Close-up(1) If there is a TPS layer, do a check of the condition and integrity of the TPS layer (Ref. AMM TASK 51-78-00-916-001):
NOTE: Airbus recommends that you always apply a new layer of TPS. This is to make sure that the TPS layer continues to give satisfactory corrosion protection. If, after the check, you think that the TPS layer is in the correct condition, you can apply a new layer as a spray on the remaining layer.
(2) If the TPS layer has local damage, remove the damaged TPS layer (Ref. AMM TASK 51-78-00-916-001) and apply a new layer of Corrosion Preventive Compound-Water Displacing & Heavy Duty Hard Film - (Material No.12ADB1) : - To the rear-spar aft face of the outer wing between RIB 11 and RIB 27 including the joint plate at RIB 22 (Ref. AMM TASK 51-78-00-916-001).
