the vertical. When new the wheel angle unloaded will be vertical or
very slightly ‘towed in’ at the bottom. A wheel sitting splayed
outwards at the bottom indicates the gear leg (or axle) has been bent,
and is no longer serviceable. If landed heavily with brakes on, or on a
rough surface, significant drag loads may be applied. Check for play
in the connections of the steel drag brace to the main gear leg and
where it attaches to TU15. Lock the brakes on and rock the aircraft
backwards and forwards to assess this. Check also the main cross
beam TU9 for straightness.
9.15.2 Nose landing gear - If the aircraft is heavily landed on the nose
landing gear the leg itself may become bent. This may not be readily
apparent from an external inspection. The weakest part is where the
leg wastes down in size to accept the suspension rubbers. If it bends
here it will usually result in increased friction in the rudder / ground
steering circuit. Press down the tail to lift the nosewheel and push the
rudder side to side. If increased friction is found, this indicates a bent
noseleg. Removing the noseleg will confirm this. It may also be
possible if overloaded to bend the large washer under the suspension
rubbers, or even drive the rubbers over the washer.
9.15.3 Wheel rims - If the aircraft is heavy landed it is possible for the tyre
to deflect to the point where the wheel rim comes in contact with the
ground, and will dent / distort. Check this visually and by spinning
the wheels. Underinflated tyres will cause this damage following
slightly less firm arrivals
9.15.4 Tube 27’s - These are the diagonal cabin brace tubes behind the pilot
and passenger seats, extending to the top corners of the cabin. These
brace the cabin and stop parallelograming of the structure sideways.
If the aircraft is landed heavily on one wheel these can be damaged –
the fittings become stretched in the tube ends and relative movement
develops. This can be checked by:
Stand just outside the cockpit with doors open Hold the wing lift struts
feel each end of the TU27’s for movement – where the insert goes into
the tube, and where the insert attaches to the airframe. If noticeable
movement exists then there is damage, and the damaged part must be
replaced.
