Nynja Operators Manual issue 2 (E) 1.2 

44 

9.15   Checks following a heavy landing  

9.15.1 Main Undercarriage  - The main gear legs will splay outwards if 

overloaded. Usually a heavy landing will be slightly wing down and 
one leg will distort more than the other. So initially observe from the 
front and check for symmetry. Check also the angle of the wheel to 
the vertical. When new the wheel angle when 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 SKR.15. Lock the brakes on and rock the aircraft 
backwards and forwards to assess this. Check also the main cross 
beam SKR.9 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 Tubes SKR.27 - 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:
