7.5.1.1 GENERAL
LANDING GEAR ASSY.
• Check condition of landing gear legs and trailing links (cracks in paint indicate overloads;
especially inspect areas of welding seams).
•
Check condition and tight connections of over-center struts and jackscrew linear actuators
(especially upper swivel joint connection of actuators and fuselage frame).
• Check proper function of trailing link springs assy. by moving wing tips up and down. Move
and rotate wheel to check friction and backlash of wheel bearings (observe section 6.5).
WHEEL DOOR ASSY.
• Check condition of composite structure of wheel doors, in particular for delaminations at
the hinges.
• Disconnect the joints of the actuation mechanism of the doors and check free movement
of doors.
• Clean and grease hinges of L/G doors if required (observe section 6.5). Reconnect joints
(spring-securing at RH ball joint!).
• Check condition and function of spring linkage of the RH door.
•
Check cable mechanism of the LH door for condition and proper installation of cables,
springs, pulleys and pulley guides and roller strut. With the gear extended, the closing
cable must have a minimum pre-load, barely free from slack. If required, adjust the
pre-load compression pressure spring of the closing cable.
• Check clearance between tires and doors to be at least 10 mm / 0.4 in. Adjust the RH door
at the ball joint and the LH door at the roller of the roller strut if required.
WHEEL BRAKES
• Check condition of brake assembly in forward fuselage and in landing gear bay (proper
routing, chang and leakage of brake master cylinder, wheel cylinders, brake uid lines
and thread ttings).
• Check condition of brake discs (wear, scratches, cracks) and brake pads.
Minimum brake lining thickness: 1.5 mm / 0.06 in
