10-104. The aircrew completes their three-minute slowdown checklist: Aircraft slows to a drop speed of 130 knots (plus or minus three knots indicated airspeed). Paratroop doors opened (if applicable). The loadmaster or flight engineer gives control of the doors to the JMs and takes a position between both jump doors. Once the safety or technical inspection of the paratroop door is complete, the loadmaster informs the JMs, “ARMY YOUR DOOR,” and takes a position in between both paratroop doors. The JM needs to confirm through the loadmaster that the aircraft has slowed to drop speed before assuming control of the paratroop door. This signal can be predetermined during the AMB, aircrew, or JM briefing before flight.Note. Jumpmasters will not assume control of the aircraft paratroop door until the loadmaster has confirmed the aircraft has slowed to 130 knots indicated airspeed.CAUTIONThe anchor line cable stop is in line with the trail edge of the jump door. This is different from the C-130, in which the anchor line cable runs further to the aft of the aircraft. The placement of the anchor line cable stop decreases the amount of workspace for the jumpmaster, safety, and jumper.DOOR SAFETY CHECK10-105. After both JMs receive, “ALL OKAY, JUMPMASTER,” from the No. 1 jumper, the AJM will give the PJM a thumbs up or verbally inform the PJM, “ALL OKAY, JUMPMASTER.” Both JMs will back up and regain control of their USLMs using the hand respective to the door they are jumping from, (right door, right hand, left door, left hand) ensuring that the USLM is not misrouted under their shoulder. The safety can assist the JM in securing their USLM.10-106. The JMs then turn towards the skin of the aircraft, remove the incorporated twist, and reestablish a proper bight. The JM assumes the No. 1 position and inspects their USLM from the USL snap hook until it disappears over their shoulder, and will then sound off with "NUMBER ONE JUMPER CHECK MY STATIC LINE." After completing the No. 1 jumper’s USLM check, the safety then inspects the JMs USLM. Once the safety or technical inspection of the paratroop door is complete, the loadmaster informs the JMs “ARMY YOUR DOOR,” and the following occurs: The safety inspects the JMs rip cord assembly to ensure the tuck tabs are in place, and the T-11 reserve parachute inserts are installed properly before the JM assumes control of the jump door. The safety will then prepare to take control of the JMs USLM. Safety personnel position themselves near the trail edge of the paratroop door, the JM secures the lead edge of the paratroop door by only grasping the metal upper or lower MEDEVAC litter support bracket. The JM hands the safety his or her USLM and sounds off with “SAFETY CONTROL MY STATIC LINE.” Then the JM grasps the trail seat back support rail on the trail edge of the paratroop door. (See figures 10-11 and 10-12 on page 10-36.) The safety controls the USLM for the JM as they perform the door safety check in the following manner: The safety grasps the JMs USLM with one hand above and one hand below their bight, keeping the USLM taut between their hands and ensuring no excessive slack is impeding the JM or causing a safety hazard. The trail hand should be held high near the USL snap hook and the lead hand held low in the vicinity of the JMs pack tray. Both hands should be formed in knife-cutting edges, palms facing outward, fingertips pointed skyward, with the USLM secured between the thumb and palm. Securing the USLM in this manner allows the safety to easily release the JMs USLM, in the event the JM prematurely exits the paratroop door.CAUTIONAll jumpers on the aircraft must enforce rip cord handle awareness at all times. Once the USLM is hooked up to the anchor line cable, the nonstatic line hand will protect or cover the rip cord handle.Notes. The JM ensures the safety has positive control of the USLM before moving toward the paratroop door.Prior to the Airborne operation, the platform locking handle should be secured with hook- pile tape or 100-mile per hour (mph) tape to prevent a potential snagging hazard for the jumpers as they approach the paratroop door.
