LANDING GEAR, WHEELS AND BRAKES
SECTION SIX
GENERAL DESCRIPTION
The main landing gear consists of two interchangeable spring steel gear assemblies and two wheel
and brake assemblies. A common center beam supports each gear half. A dowel pin and clamp is
used to hold the gear in place. The beam is mounted to left and right plates, both of which are
bolted to the lower forward fuselage frame. All landing gear attach points should be carefully
inspected for wear and damage during landing gear checks. Always place the aircraft on jacks prior to
performing any maintenance procedures on the landing gear system.

B. Remove fuselage skins as required.
C. Disconnect flexible hydraulic brake line and plug to prevent leakage and contamination.

E. Remove inboard clamp bolts.
**CAUTION**
The gear is extremely heavy and needs to be handled
accordingly to prevent personnel injury and/or
damage to the gear.
F. With the gear supported, lower it down off and away from the dowel pin. It may be
necessary to pry the gear apart.
