1.11 Landing Gear
The main landing gear consists of two special steel spring-leaf struts (1) positioned crossways to fuselage for elastic
cushioning of landing loads.
The two steel spring-leaf struts are attached to the fuselage underside via the main girder.
Two rawhide liners (2 3) are inserted between each spring-leaf and the girder. Two bolts (5) and nuts secure the individual
spring-leaf to the edge of the girder via a light alloy clamp (4) while a single bolt (6) and nut secures the inboard end of the
leaf-spring to the girder.
Figure 1-6 Main landing gear
Wheels are cantilevered on gear struts and feature hydraulically actuated disc brakes (see fig. 4-13) controlled by a lever (1)
located on cabin tunnel between seats. Main gear wheels mount Air-Trac type 5.00-5 tires inflated at 23 PSI (1.6 bar).
Hydraulic circuit shut-off valve (2) is positioned between seats. With circuit shut off, pulling emergency brake lever
activates parking brake function.
Braking is simultaneous on both wheels via a “T” shaped joint (6).
Control lever (1) activates master cylinder (3) that features built-in brake-fluid reservoir (4). The brake system is equipped
with a non-return valve (5), which insures that braking action is always effective even if parking brake circuit should
accidentally be closed.
