3.2.94.12 Parachute, seat-type. A parachute designed for attachment to the saddle of the harness and may serve as a seat cushion in certain types of aircraft.

3.2.94.13 Parachute, troop. A parachute used by paratroopers for a premeditated jump over a designated area.

3.2.94.14 Pilot chute. A small parachute used to accelerate deployment of the main parachute. Some pilot chutes are equipped with a metal spring device to open the canopy when released from the pack.

3.2.95 Pilot chute frame. A wire frame or spring used in the pilot chute to initiate the opening action of the chute upon release from the pack.

3.2.96 Pin, locking (ripcord). A short metal pin attached to the ripcord cable that is inserted into a pack cone or other device to secure the flaps as a function of closing a parachute pack.

3.2.97 Pocket, log record. A small patch pocket sewn to the pack or riser for carrying the parachute log record.

3.2.98 Radial seam. The seam sewn from skirt to vent holding gores together and used as a guide for the suspension lines for round type parachutes. This term is normally used in lieu of main seam for ribbon-type parachutes.

3.2.99 Reefing rings. The rings sewn to the skirt of a canopy at suspension line attaching points through which the reefing line is passed.

3.2.100 Reinforcement tapes. Any tape or webbing sewn to a pack or canopy at a point of high load to distribute the load and strengthen the fabric.

3.2.101 Release, canopy. A device that is designed to permit rapid separation of the canopy and risers from the suspended load.

3.2.102 Release, harness. A device that is designed to permit rapid release of the harness from the wearer.

3.2.103 Release, 3-ring. The rings and webbing that compose a riser/canopy release mechanism consisting of three interlocked rings of graduated size..

3.2.104 Ribs. The airfoil shaped panels that are attached to the upper and lower gliding surfaces in the chordwise direction, generally for a ram-air gliding type parachute but may refer to internal structure of some round type parachutes.

3.2.105 Rib panel reinforcements. The tapes that are sewn on the ribs.
