118. Retract A-frame shootbolts and rotate the A-frame to stowed position.
A-frame shootbolts will not retract.
Press and hold the A-frame ROTATE DEPLOY button on the interface
enclosure. Release shootbolt/s.
Check for security of the A-frame rotate shootbolt housing - tighten the A-
frame rotate shootbolt housing if necessary. Report any adjustment to

Remove the shootbolt handle and retract the shootbolt pins from opposite
side.
Check for housing distortion. Report damage to maintenance.
Check the alignment of holes.
♦ If holes are out of alignment report defect to maintenance so that the A-
frame stop pads can be re-shimmed.
♦ If the misalignment is fore and aft. Report to maintenance so that re-
shimming of the A-frame stop pads can be carried out.
♦ If the misalignment is vertical then check for excessive hinge bush wear.
Report any wear to maintenance
Check rotate cylinder mounting points to ensure pins are in place and
secure.
If rotate cylinders appear to be functioning check for mechanical obstruction,
check all hinge points, clean and lubricate as required. Report any
damage/deformation to maintenance.
119. Stow far bank support.
Check the far bank support upper shootbolt is fully retracted.
If shootbolt can not be retracted, check R clip is removed and the weight of
far bank support is fully taken with the tail lift. DO NOT apply too much
pressure, this will prevent the shootbolt being released.
Check that the far bank support lower shootbolt is fully retracted.
