Main Landing Gear Areas
(a) Examine the main landing gear area as follows: 1) Examine the outer and inner cylinder lugs for distortion, cracks and other types of damage.
2) Examine the side brace, drag brace, trunnion link, forward and aft trunnion attachments, and torsion links for cracked paint, distortion, or other damage.
3) Examine the gear side brace downlock linkage for cracks or other types of damage. 4) Look at the hydraulic fluid levels in the shock struts. a) Do a two-point servicing check or service the shock struts per AMM 12-15-31.

b) If a high drag or side load landing, and a hard landing occur at the same time, or the shock strut servicing was not correct, remove the main gear inner cylinders.
1.
Dimensionally check the barrel of the inner
_ cylinder, truck beam, and axles for distortion or bending, and examine for cracking.
2.
Inspect the interior components of the shock strut
_ for damage. 5) Examine bolts and pin connections in the main gear (not inspected in Phase I) for distortion.
(b) Remove trunnion link per AMM 32-11-11/401, and NDT inspect the forward trunnion fuse bolt (Fig. 204). 1) Remove grease reservoir and inspect the aft trunnion fuse
nut to ensure nut is secure and not cracked or distorted (Fig. 205).
NOTE: This inspection should be done only after the
____ trunnion link has been reinstalled.
2) Remove the retention pin for the main landing gear outboard fuse pin, and rotate the pin to ensure no crank-shafting or deformation of the pin (Fig. 201 and 202).

(5) Nose Landing Gear Areas
(a) Examine the nose landing gear areas as follows:
1) Look at the hydraulic fluid levels in the shock struts. Do a two-point servicing check or service the shock struts per AMM 12-15-41. a) If a high drag or side load landing, and a hard landing
occur at the same time, or if the nose gear hits hard, remove the nose gear inner cylinders. Do this also if the shock strut servicing was not correct.
1.
Dimensionally check the barrel of the inner
_ cylinder and axles for distortion or bending, and examine for cracking.
2.
Inspect the interior components of the shock strut
_
for damage.
2) Make sure the nose wheel steering system operates correctly and the steering mechanism is rigged correctly (AMM 32-51-00/501).
3) If any landing gear wheels are removed because of a blown tire, do the steps that follow (AMM 05-51-54/201): a) Examine the nose wheel structure for cracks. b) Examine the nose wheel bearings for smooth operation
(no roughness).

(6) Fuselage:
(a) Examine the lower fuselage structure for skin buckling, flaking paint, cracks, and loose fasteners.
NOTE: Examine the area below the body crease and from station
____
727 to 100 inches aft.
1) Make sure the fasteners are installed in the correct positions.
(b)
Examine the wing to fuselage joints at stations 540 and 664 for distortion, flaking paint, cracks and loose fasteners. 1) Make sure the fasteners are installed in the correct
positions.
(c)
Examine the upper fuselage structure between S-6 LH and S-6 RH at station 540, 664 and 727 for buckling, distortion, flaking paint, cracks and loose fasteners. 1) Make sure the fasteners are installed in the correct
positions.
(d)
Examine the bulkheads at body stations 294.5 and 360 and the fuselage structure immediately outboard of the nose wheel well for buckling, flaking paint, cracks and loose fasteners.
