Node Plate (Critical Part)
Visually inspect the Node plate for any signs of damage or strain. Replace on the
recommendation of a Competent Person / Inspector.
Seat Base Assembly and the Recoil Dampers
Visually inspect for any wear or damage and ensure that all bolts, clevis’ and other
fasteners are fully secure. Ensure that clevis pin threads are not visible on damper rods.
Check to ensure that there is no sign of any fluid leaking onto the damper rods.
Suspension
Check the condition and operation of the springs. Check for signs of deformation or
cracking. If the springs show excessive corrosion (pitting or flaking of wire), or if springs
have taken a pre-compression set then they should be changed out. Springs can be
susceptible to yield over time. This can be verified by measuring the deflection of the seat
base in-situ. The following check is recommended to identify whether the springs are fit for
purpose: In-situ spring check: the top of the sliding sleeve should rest against the
compression stop. If a space exists greater than 10mm, then the spring should be replaced.
Recoil Dampers
Ensure that the damper rod-end threads are not visible below the clevis pin eye. Ensure no
sign of any fluid leaking onto the damper rods. Recoil Dampers should also be disconnected
at one end so that their operation can be checked and to check for any bowing of the
damper rods.
Check the spring compression plate for any signs of deformation.
