This chapter contains aircraft descriptions, JM procedures, and aircraft preparation techniques for nonstandard rotary-wing and fixed-wing aircraft. The aviation supporting unit prepares the aircraft for equipment and personnel drops to include seat and door removal or installation and rearrangement of seat belts. The installation of a field expedient anchor line cable is the jumpmaster’s responsibility. Aircraft preparation is usually accomplished jointly by the loadmaster or crew chief and JM. These aircraft are service tested and approved for personnel airdrop operations.
