Aircraft Nose Gear Shock Strut Operation and Servicing

Nose gear shock struts often have attachments for external shimmy dampers to control oscillations.
Some nose gear struts are equipped with a locking or disconnect pin for quick turning during towing or positioning.
Nose and main gear shock struts on aircraft are equipped with jacking points and towing lugs for maintenance and towing.
Shock struts contain an instruction plate near the filler inlet and air valve assembly for filling with fluid and inflating.
It is crucial to follow the instruction plate for the correct type of hydraulic fluid and pressure for inflating the strut.
The inner construction of a shock strut involves fluid movement during compression and extension, controlled by a metering pin.
The compression stroke begins as the aircraft wheels touch the ground, with the strut compressing and the metering pin controlling fluid flow.
During taxi operations, the air in the tires and the strut combine to smooth out bumps.
Insufficient fluid or air in the strut can cause the compression stroke to not be properly limited, resulting in impact forces.
Efficient operation of the shock struts requires proper maintenance of fluid and air pressure, including deflating and servicing the strut.
Two common types of high-pressure strut servicing valves are the AN6287-1 valve rated to 3,000 psi and the MS28889-1 valve rated to 5,000 psi.
The procedure for servicing shock struts involves positioning the aircraft, checking the swivel nut, and depressurizing the valve core if present before deflating and servicing the strut.
