8.13 NOSE UNDERCARRIAGE LEG
8.13.1 DESCRIPTION
The nose gear comprises a steerable nose wheel mounted on a welded steel assembly with an
aluminium wheel yoke and a rubber spring system.
Several variations of the steel leg assembly have been used on different aircraft models.
On earlier aircraft the wheel yoke is bolted together (Figure 70) while later models use a 1-piece part.
The steel tube is constrained within two Ertalite bushes mounted in a housing which is attached to
the front of the firewall. For some models this housing is moulded in fiberglass, however for the
majority an Aluminium housing is used.
Nose wheel steering is achieved by connecting the rudder pedal assembly to the nose wheel
steering link by push rods. The nosewheel is centred by springs. Some models incorporate a rubber
“soft link” between pedals and nose leg to improve ground handling.
A nose wheel speed fairing (wheel spat) is standard equipment.
Refer to Section 12 for views of the entire leg / steering assembly.
