The 15 foot extraction parachute has no age or service life. f. Inspection Function Requirement. Normally, a technical/rigger-type inspection will be performed by airdrop equipment maintenance personnel at a packing, rigging, or repair activity. The inspection of initial receipt items will be performed as a separate function from packing or rigging activity; the item to be inspected will be placed in proper layout on packing table or suitable sized floor area. Should defect or damage be discovered at any point during the inspection, the inspection will be terminated and the applicable item will be processed and forwarded to repair activity. The repair activity, in turn, will conduct a technical/rigger-type inspection that will be performed by only those parachute rigger personnel cited in AR 750-32, Airdrop, Parachute Recovery and Aircraft Personnel Escape Systems. The repair activity inspection of parachutes will be made on a shadow small cargo table. Any defect discovered during a unit level repair activity inspection which exceeds the capability of that activity will require the affected item to be evacuated to an intermediate direct support (DS) maintenance function for further determination of economic repair and repair accomplishment, if applicable. 2-10
