MAIN CANOPY GORE, EXTENDED GORE AND SECTION REPLACEMENT
CAUTION
Structural soundness of the main canopy can be seriously degraded, if more than the
allotted gore or section panel replacements are completed on the main canopy through its
lifecycle.
During the lifecycle of the main canopy (figure 15) the limitations for gore replacement, extended gore,
mesh netting and the section panel replacements are as follows: replacement of 3 entire gores and not
more than 3 section replacements on the A&D section panels, and 8 section replacements on the B&C
section panels. A section panel can only be replaced once throughout the lifecycle of the main canopy.
These are the maximum section panel replacements that can be performed throughout the lifecycle of the
main canopy. Only authorized manufactured section panels will be used when performing gore, extended
gore, mesh netting and section replacements on the main canopy.
Limitations. When the maximum replacement panels have been installed on the main canopy, for
instance if the maximum section panels have been replaced on the A&D section panels previously and
another A&D section panel needs to be replaced the main canopy will be deemed beyond economical
repair (BER) no other repairs can be made to the canopy.
Gore Replacements (ABCD Section Panels). Only 3 entire gore sections can be replaced throughout
the lifecycle of the main canopy. Gore replacements will be replaced as an entire gore assembly. The
individual sections panels required for the entire replacement of the gore are to be sewn together prior to
being sewn onto the main canopy. Detailed replacement procedures can be found in WP 0028 00.
NOTE
If a gore replacement is required and the canopy has been repaired previously with the
maximum 3 sectional replacements on sections A&D the canopy will be deemed beyond
economical repair (BER). This will also apply to sections B&C.
A&D Section Replacements. Only 3 sections on both the A&D panels can be replaced throughout the
lifecycle of the main canopy. When the three section panels have been replaced on either A&D sections, if
additional damage occurs to any of the A&D section panels and a replacement is required the canopy
shall be placed out of service as BER.
B&C Section Replacements. Only 8 section panels can be replaced on the B&C section panels
throughout the life cycle of the main canopy.
Extended Gore Replacements. Extended gores can be replaced on either side but are limited to only 2
extended gore replacements throughout the lifecycle of the parachute. Replacements will be in
accordance with the procedures outlined in the specific WP 0029 00 and WP 0030 00.
Mesh Netting Replacements. Replacement of the mesh netting panels, all 3 Mesh netting panels can
be replaced only one throughout the lifecycle of the main canopy. Replacements will be in accordance
with the procedures outlined in the specific WP 0031 00.
