TECHNICAL DESCRIPTION, OPERATING, MAINTENANCE AND REPAIR MANUAL
1.6.6.3 Nose wheel leg
The nose wheel leg of the retractable undercarriage( Fig.3) position ( B) is fixed into
the engine bed. The nose wheel leg is the wheel arm towed type.
The damping of the arm is carried out with the flexible elements from polyurethane,
which are located in the tube of the leg ( B ). The nose undercarriage leg is retracted
backwards. The drag stay ( KS ), which is connected with the piston of the hydraulic
face ram provides for the movement of the nose undercarriage. The gas strut ( GF )
provides for the emergency extension of the nose undercarriage. This gas strut
extrudes the drag stay into the arrested position.
The control of the nose undercarriage leg is carried out with help of the control cables
( KZ ) „Cabelcraft“ type connected with the rudder pedals.
