2. Retacking. Replace broken or loose tacking which secures the buffer in the deployment line attaching
loop by retacking according to original tacking details, using one turn double ticket No. 8/7 waxed cotton
thread at each of three tacking points. Secure the tacking ends at each tacking point with a surgeon’s
knot and locking knot. Trim tie ends to ½-inch.
3. Replacing a loop buffer. Replace a damaged or missing deployment line attaching loop buffer on the
cotton deployment bag bridle by fabricating as follows:

loop. Ensure the loop material is not damaged during the cutting process.
b. Cut a 7 ½-inch length of 1 ¾-inch wide, type VIII, nylon webbing and wax the ends.
c. Double the webbing length and position the folded webbing in the original buffer location within the
bridle deployment line attaching loop.
