K L Line-over.  A type of deployment malfunction that occurs  when one or more suspension lines pass over the top of the  canopy during deployment preventing complete, normal  inflation. Not to be confused with “partial inversions.” Kicker plate.  A launching disc which is placed under the  pilot chute. Kill-line collapsible bridle.  A main pilot chute bridle  configuration whereby the pilot chute is collapsed by use of  a retractable centerline after it has deployed the parachute. Locking cone.  A cone shaped metal device used in  conjunction with end tabs and ripcord pins to hold the  container flaps closed. Locking pins.  Straight or curved metal pins used with  a throwout or pull-out pilot chute for securing the  container closed. L/D.  Lift to drag ratio. Lap parachute.  A parachute that rests in the lap of the wearer  and attaches to the harness with risers to snaps and D-rings  on the front. Resembles a chest parachute with long risers.  Not in current use. Locking ripcord pin.  A small metal prong, slightly smaller  in diameter than the ripcord cable and fastened to it by means  of a swage fitting or serving and solder. One pin is attached  to the end of the cable and the others (when two or more are  used) are set at intervals on the cable. The spacing of the  pins is dependant on the distance between the cones on the  container flap. The locking pins pass through the locking  cones of the flaps and thus serve to lock the container until  such time as the pins are withdrawn.  Lateral band.  Lower (in the periphery) or upper (in the vent  hem), a reinforcement web. Launching disc.  A kicker plate placed under the pilot chute. Lockstitch.  Type of stitching used in manufacturing  parachutes. This type of stitch is formed by two threads. A  loop of the thread is passed through the material where it is  entered by the supply of the other thread. The loop of the first  thread is drawn into the material to the extent that the loop or  lock is approximately halfway between the two surfaces of the material. Also known as a type 301 stitch. Leg strap.  That part of the harness webbing that encircles  the wearer’s leg. The leg straps can be adjusted to fit the user. Life cycle.  Service life. The time that a parachute may be  considered usable. Lift web (main).  The portion of the harness from the shoulder  to the hip area; generally from the canopy releases to the leg  strap junction. Loft.  A facility for the repair and maintenance of parachutes. Logbook. A format for complying with 14 CFR part 65,  subsection 65.131(a) in regards to recording the work done  by the rigger on parachutes. Lift webs.  The front portion of the harness from the shoulder  to the leg strap junction; includes the risers if there are no  riser releases. Lift.  The force perpendicular to drag that helps reduce  vertical descent. Line extension.  When the lines are fully deployed; prior to  line stretch. Machine head.  The entire metal housing that supports the  moving parts and bearings of the machine. Main parachute.  A parachute assembly, excluding the  harness, that is used in conjunction with a reserve parachute  assembly as the primary assembly for a premeditated jump. Line separator.  A tool used to separate and hold the lines  of a round parachute during the packing process. Main seam.  That which joins two adjacent gores in a canopy;  also known as a radial seam. Line stowing.  The process of drawing the suspension lines  into suspension line retaining loops in the parachute pack;  accomplished to prevent entanglement or twisting of the  lines during opening of the parachute. Stows may be held  by retaining loops or rubber bands. Maintenance.  Inspection, overhaul, repair, preservation, and  replacement of parts but excludes preventative maintenance. Line stretch.  Occurs during deployment, after the lines are  fully extended. Follows snatch force and line extension. M  G-6
