(1) Do the inspection of the main landing gear and support structure.
(a)
Make sure the shock strut pressures are normal and the hydraulic fluids are at the correct levels (AMM 12-15-01/301).
(b)
Lift the airplane with jacks (Ref 07-11-01/201).
(c)
Examine the inner and outer cylinder lugs.
(d)
Examine all structural components of the main landing gear and carefully examine the components that follow: 1) Shock strut 2) Trunnion link 3) Drag strut 4) Torsion links 5) Truck beam (near inner cylinder forks) 6) Side strut 7) Downlock 8) Truck Position Actuator (the actuator that sets the angle
of the truck beam for retraction and extension 9) Strut doors and the mechanism that retracts and extends the doors.
(e)
Examine the support structure of the main landing gear and carefully examine the components that follow: 1) Landing Gear Beam 2) Support fittings for the landing gear beam
-Inboard
-Outboard
3) Trunnion support fittings and attachments
-Forward
-Aft
4) Stabilizer links and fittings between the rear spar and landing gear beam
-Inboard
-Outboard
5) Body fitting for side strut attachment.
(f)
Examine all of the pin joints and fuse pin connections.
(g)
If you found tire damage in Phase 1, do the steps that follow. 1) Remove and examine the sheel structure. 2) Remove and examine the brake assembly. 3) Examine the axles.
(h)
If one or more of the conditions that follow occurred; remove, disassemble, and examine all parts of the shock strut (AMM 32-11-01/401). 1) The shock strut pressures were sufficiently low to cause
damage. 2) The hydraulic fluid levels were sufficiently low to cause damage.
