 B.  Airplane Inspection
 S 212-005
 (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.

 3)  You found damage to one or more of the parts during your inspection of the landing gear.
 (i)  
Make sure the main landing gear retracts and extends correctly (AMM 32-32-00/501).

 (j)  
Lower the airplane from the jacks (AMM 07-11-01/201).

 S 212-008
 (2)  Do the inspection of the nose landing gear and support structure.
 (a)  
Make sure the shock strut pressures are normal and the hydraulic fluids are at the correct levels (AMM 12-15-02/301).

 (b)  
Lift the nose of the airplane with jacks (AMM 07-11-01/201).

 (c)  
If you found tire damage in the Phase 1 inspection, do the steps that follow: 1) Remove and examine the wheel structure. 2) Examine the axle.

 (d)  
Examine all structural components of the nose landing gear and carefully examine the components that follow: 1) the shock strut 2) the torsion links 3) the drag strut 4) the lock links.

 (e)  
Examine the wheel well area and carefully examine the parts that follow: 1) the web (the left and right side walls) 2) the aft bulkhead 3) the trunnion attachments 4) the drag strut attachments.

 (f)  
If one or more of the conditions that follow occurred; remove, disassemble, and examine all parts of the shock strut (AMM 32-21-01/401). 1) The shock strut pressures were sufficiently low to cause

 damage. 2) The hydraulic fluid levels were sufficiently low to cause damage. 3) You found damage to one or more of the parts during your inspection of the landing gear.

 (g)  
Make sure the steering system is adjusted and operates correctly (AMM 32-51-00/501).

 (h)  
Make sure the nose landing gear retracts and extends correctly (AMM 32-34-00/501).

 (i)  
Lower the nose of the airplane from the jacks
 (AMM 07-11-01/201).
