REPAIR
NOTE
The following procedures describe basic netting repairs normally required. This should
not be understood to mean that these repairs are the only authorized repairs. Any time
supervisory parachute maintenance personnel determine that other repairs are
necessary to maintain the basic integrity of the net assembly, they may be made using
the following basic criteria.
Procedures in WP 0118 00 may be used to modify the zig-zag sewing machine presser
foot which will assist in the repair and replacement of the anti-inversion net.
Due to the net not bearing any weight, the objectives in making repairs to the net are as follows: to
prevent damage to the parachute's suspension lines and lower lateral bands; to avoid excessive
accumulation of net material during repairs; and to maintain the net in a serviceable condition at minimum
cost. To achieve these objectives, the following guidelines are to be followed in making inspections and
repairs:
1. A limit of two horizontal and two vertical net cords may be broken in any one net section without
repair. Trim the broken cord to within 1/4-inch from where the cord crosses the horizontal or vertical
cord, as shown in figure 1. Only one unrepaired break per net is permitted.
