a)
Correct engine oil level using the dipstick inside the oil tank.
A8 Freedom and Integrity of Control Rods
Check:
a)
Condition and security of the safety points on the control rods, linkages, bearings and fiberlock nuts. There should be
insignificant play in the “Uniball” rod-end bearings and no evidence of corrosion or damage. The control rods should be
straight and undamaged. The control rods should be free to rotate slightly around their axis when gripped and given a light
twist. Any undue force needed or inability to twist the bearing may indicate a problem of the bearing and should be further
investigated.

a)
All the rotor head securing nuts are secure and that all the safety locking systems are present and functional;

Examine as far as possible the rotor head and hub-bar assemblies for cracks, damage, wear, corrosion and rubbing;
c)
The state of the pre-rotator ring-gear teeth and make sure they are not damaged or excessively worn;
d)
Make sure the pre-rotator flexible shaft and the Bendix pre-rotation gear are adequately coated with grease.
A10 Undercarriage Right Hand Side
Check:
a)
State and safety of the undercarriage leg and mounting bolts.
A11 Wheels and Wheel Spats
Check:
a)
State and safety of the anchoring of the wheel, hub, axle and wheel spats;
b)
All the tyres for damage and check tyre pressures are correct;
c)
Check for damage, rubbing marks on the tyres and position of creep marks;
d)
The brake lines and make sure there is no evidence of bending or chafing.
Either roll the gyroplane forward or remove the wheel spats to check the whole of each tyre.
Ensure any dirt and debris has been removed from inside the wheel spats.
Check
the
function
of the braking system.
