 NOSE GEAR - DESCRIPTION AND OPERATION
_____________________________________
 1.  General (Fig. 1)
_______
 A.  The nose gear provides directional control and supports the forward end of the airplane while on the ground. The nose gear consists of a shock strut, drag strut, lock link, lock springs, torsion link, and tow fitting.
 2.  Component Details
_________________
 A.  Drag Strut (Fig. 1)
__________
 (1)  
The drag strut carries forward and aft loads and stabilizes the shock strut. The drag strut is hinged in the middle and consists of an upper and a lower strut. The upper strut attaches to the wheel well side walls and the lower strut attaches to the shock strut outer cylinder. During retraction the drag strut folds in the middle.

 B.  
Lock Link (Fig. 1)

_________
 (1)  
The lock link consists of a forward lock link, and an aft lock link. The forward end connects at the hinge point of the drag strut and the aft end attaches to the wheel well aft wall. The links lock in an overcenter position to keep the nose gear extended or retracted until the lock actuator (Ref 32-34-00) unlocks it.

 C.  
Lock Spring (Fig. 1)

___________
 (1)  
The lock springs attach to the aft lock link and to the forward lock link. The springs keep the lock link in the overcenter position until the lock actuator supplies a force to stretch the springs out of the locked position.

 D.  
Shock Strut (Fig. 2)

___________
 (1)  
The nose gear shock strut is the main supporting member of the nose gear. The shock strut consists of an inner cylinder and an outer cylinder. The outer cylinder is connected to the wheel well side walls with trunnion pins and the inner cylinder slides within the outer cylinder.
