ARMY TM 10-1670-279-23&P AIR FORCE T.O. 13C5-27-2 NAW NAVAIR 13-1-28 Section IV. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) Paragraph Page 2-9 PMCS Procedures............................................................................................................... 2-10 2-9. PMCS Procedures. The following describe PMCS procedures on the unit and intermediate direct support (DS) levels. a. General. Table 2-1 lists preventive maintenance checks and services. The purpose of PMCS is to ensure that the 22-foot diameter cargo extraction parachute is operational. b. Frequency of Performing PMCS. PMCS will be performed before equipment is packed for use, during modification and repair after use, or at any time deemed necessary by the air delivery equipment maintenance officer. c. PMCS Columnar Entries, Table 2-1. Enter data in columns as follows: (1) Item number. The item number column shall be used as a source of the item number required for the "TM Number" column on DA Form 2404 (Equipment Inspection and Maintenance Worksheet) when recording the results of PMCS. (2) Interval. This column identifies the required PMCS interval. (3) Item to be inspected. Contains the common name of the item to be inspected. (4) Procedures. Provides a brief description of the procedure by which the checks are to be performed. d. Recording Defects. All defects discovered during the inspection will be recorded using the applicable specifics in DA PAM 738-750, DA PAM 738-751, and TB 43-0002-4. e. Overage Items. The 22-foot cargo extraction parachute has no age or service life. f. Inspection Function Requirement. Normally, a technical/rigger-type inspection will be performed by air delivery 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 defects 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 a 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 small cargo parachutes will be made on a shadow 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. NOTE Parachutes which are deemed unserviceable by a packing or rigging activity will be rigger-rolled prior to being sent to a repair activity. 2-10
