MAIN LANDING GEAR - INSPECTION/CHECK
1. General
A. Periodic inspection of the landing gear is described in paragraph 2. A special inspection is necessary after a hard landing, after a brake seizure when the airplane is being towed, or is moving at high speed on the ground, after the gear has collided with an obstacle, and after a high energy stop. For special inspections refer to Chapter 5.
2. Main Landing Gear Inspection
A. Equipment and Materials
(1) Axle nut thread gage - F80198
B. Examine main landing gear.
(1)
With power off, check main actuator and all hydraulic connections for leaks.
(2)
Check shock strut for leaks and specified extension. Examine exposed surface of inner cylinder for dirt scratches or galling.
(3)
Examine main gear tires and wheels. Refer to Main Gear Tires and Wheels -Inspection/Check, 32-45-0.
(4)
Check safety switch sensors, and all electrical wiring for security and chafing.
(5)
Check hydraulic hoses for chafing, and static discharge wire for loose attachment and failure to contact ground.
(6)
Examine torsion links and lower drag strut attachment for tightness, missing cotter pins, lockrings and lockbolts.
(7)
On right gear check also ground speed brake operating cable for damage corrosion and security of attachments.
