B. Inspection of the NLG
(1) Do a General Visual Inspection of the protective finish on the surface of the NLG and its components for damage.

If the protective finish or primer layers are damaged, do a repair (Ref. AMM TASK 32-21-00-100-001).

(2) Do a General Visual Inspection of the shock-absorber sliding tube and the chrome plating on the NLG retraction actuator and downlock-release-actuator rods. Do a check for wear, scores and damage.
If:

the chrome surface of the shock-absorber sliding tube, or
the chrome plating on the NLG retraction actuator, or
the NLG downlock release actuator
are possibly dry, put a small quantity of Mineral Hydraulic Fluid-Damper - - (Material No.02BBB9) on a clean Textile-Lint free Cotton - (Material No.14SBA1) .
Apply a thin layer of hydraulic-fluid on the chromium surfaces.

(3) Do a General Visual Inspection of the NLG hydraulic hoses and rigid pipes.
Make sure that:

the Hydraulic Hoses and Rigid Pipes are correctly installed and clamped. Do a General Visual Inspection for distortion, cracks, damage and signs of fretting because of vibration.
All the hoses are installed in their correct location and are not twisted.
There are no signs of hydraulic leakage from the unions.
All the brackets, line support blocks and clamps are correctly installed and safetied.
There is the correct clearance between all hydraulic pipelines and their related structure.

(4) Do a General Visual Inspection of the NLG Electrical Conduits, Connectors and Protective Coverings.
Make sure that:

All the electrical conduits, connectors and protective coatings are in good condition.
All the electrical connections and connectors are correctly installed and safetied.
There is no fluid contamination.
If necessary, clean the area of contamination.
