WARNING
Upper and middle control line assembly will be
replaced as an entire assembly if any one of the
upper and middle control lines in the control line
assembly is damaged. Failure to follow these
replacement procedures may have adverse effects
on the performance of the main canopy and may
result in a malfunction of the parachute and severe
injury or death to personnel.
NOTE
Procedures in this work package will be used to replace the left or right aft control line
assembly. The left and right aft control line assemblies are mirror images of each other.
Both sides are installed in the same manner described in this work package.
Replace a damaged control line assembly as follows:
1. Place canopy in proper layout
2. Invert canopy between lines 1 and 28.
3. Straighten the control line assembly, ensuring that it is free and clear from all attaching points in the
canopy to the junction with the lower (red) control line down to the control toggle. Ensure that there
are no twists, entanglements or knots.
4. Align the new control line assembly on top of the damaged control line assembly and pin the new
control line assembly next to the attaching points as this will assist in re-attaching the new control line
assembly. Reference the control line assembly diagrams in this work package to ensure the control
line assembly has been correctly routed and attached to the canopy.
5. Replace the left or right aft Control Line assembly in this order:
a.
Middle Control Line Assembly
b.
Upper Long Control Line
c.
Upper Short Control Line
d.
Extended Gore Limiter Line
e.
Lower Control Line
