9-14. The PJM is responsible for the inspection of the jumpers on the aircraft before an Airborne operation. Only by a complete and systematic equipment inspection of each jumper can the PJM ensure that personnel aboard their aircraft are safe to jump. Jumpmasters must observe all jumpers don the equipment, and make corrections as needed to prevent deficiencies. Buddy rigging is used: The buddy system is a systematic method of donning and adjusting the main and reserve parachutes. It provides an additional safety check, prevents unnecessary delays during JMPI, and provides the jumper with the maximum amount of comfort while wearing the parachute harness. To increase efficiency and reduce risks, jumpmasters are encouraged to gather the chalk and provide a demonstration of the buddy system prior to donning parachutes. This is especially beneficial during reintegration jumps. If a jumpmaster rigs a jumper, it is acceptable for the jumpmaster to JMPI that jumper. The rigging procedures and the JMPI sequence are two different systematic checks. However, if another JM is available, then that JM should not inspect the jumper that they rigged.Note. ALL PERSONNEL must utilize the buddy system to don the main and reserve parachute,INCLUDING THE JUMPMASTERS upon their completion of JMPI.
