## MC-4 RAM AIR FREE-FALL PERSONNEL PARACHUTE SYSTEM PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) 

## GENERAL 

The following describe PMCS procedures on the unit and direct support levels. The PMCS table has been provided to ensure the MC-4 parachute is in proper operating condition and ready for its primary mission. 

Warnings and Cautions. Warnings and cautions appear before applicable procedures. You must observe these WARNINGS and CAUTIONS to prevent serious injury to yourself and others, and to prevent damage to equipment. 

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. 

## PMCS Columnar Entries Table 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 the PMCS. 

Interval. This column identifies the required PMCS interval. 

Item to be Inspected. Contains the common name of the item to be inspected. 

Procedures. Provides a brief description of the procedures by which the checks are to be performed. 

Recording Defects. All defects discovered during the inspection will be recorded using the applicable specifics in DA Pamphlet 750-8, DA Pamphlet 738-751 and TB 43-0002-43. 

Over Age Items. During any inspection, or at any time that an item is found to be over age (i.e., shelf/service-life has expired as specified in TB 43-0002-43), the item will be removed from service, condemned, and tagged, in accordance with DA PAM 738-751. 

Conservation of Resources. To conserve time and labor, and to avoid evacuation to a direct support maintenance activity, unit/detachment commanders may designate, in writing, rigger personnel to accomplish classification inspection of over age air delivery equipment and the classification of Beyond Economical Repair (BER) parachutes. 

Inspection Function Requirement. Normally, air delivery equipment maintenance personnel at a packing, rigging, or repair activity will perform a technical/rigger-type inspection. 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 a 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. The repair activity inspection of personnel parachutes will be made on the light table. 

Any defect discovered during a unit level repair activity inspection, that exceeds the capability of that activity, will require the affected item to be evacuated to a direct support maintenance function.
