SECTION 6 – LANDING GEAR and BRAKES
6.1
LANDING GEAR
Main gear comprises two separate composite beams which are bolted to the fuselage at
the top and centre and to the wheel stub at the bottom.
The nose gear is a welded steel, trailing arm assembly with a rubber spring system. The
nose wheel is steerable with the rudder pedals.
Nose Wheel and Main Wheel Speed Fairings (wheel spats) are optional equipment.

MAIN GEAR
Figures 12, 15 an 14 illustrate the main landing gear. The illustrations should be used in
conjunction with the following procedures during removal and installation of component
parts.
WARNING: Check looseness of main U/C beams by lifting each wing and trying to
move beam back and forth. If movement, tighten clamp bolts (2) evenly to take
beam movement out. Do not over tighten or exceed 3 threads clear on the nuts
(use extra washers). Over tightening can cause bolt fracture and failure to tighten
both can also cause bolt failure.
(See Torque Value Figure 1-2).
The wheels comprise two wheel halves which are assembled as shown in Figure 15.
During assembly of the main wheels the through-bolts/nuts should be tightened to the
value specified in Table 2.
The assembly of the wheels to the undercarriage leg is shown in Figure 14.
