NOSE GEAR
1. DESCRIPTION
The nose gear consists of a tubular steel strut attached to the engine mount. The free castering nose-
wheel’s maximum turning arc is 216 degrees (108 degrees either side of center). Shock absorption is pro-
vided by a series of stacked, polymer pucks which react against the engine mount. Steering is
accomplished by differential application of the main gear brakes. The wheel, axle, tire and tube, wheel
bearing, and seal are mounted on the nose gear. (See Figure 32-202)
