REPLACE
Replace missing or damaged vent lines as follows:
1. Remove an original vent line by cutting the stitching at each end of the line.
2. Cut a length of ¾-inch wide tubular nylon webbing equal to the length of an adjacent affixed vent line;
sear the ends.
3. Mark the webbing length at points six-inches from each end.
4. Position one end of the webbing length in the original location of one vent line and align the six-inch mark
with the upper edge of the vent reinforcement band (upper lateral band).
5. Beginning at a point 1/8-inch back from the vent reinforcement band (upper lateral band) upper edge,
secure the positioned webbing end to the radial tape by stitching two 5/32-inch wide rows of double-throw
zig-zag stitching to a point ½-inch beyond the positioned webbing length. Stitching will be made using the
specifics in Table 2, WP 0046 00, SEWING PROCEDURES.
