PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
The following describe PMCS procedures on the unit and direct support levels. The PMCS table has been
provided to ensure the 28-Foot Diameter Cargo Extraction 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
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 airdrop equipment maintenance
PMCS Columnar Entries Table 1. Enter data in columns as follows:
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.
Interval. This column identifies the required PMCS level.
Item to be inspected. Contains the common name of the item to be inspected.
Procedures. Provides a brief description of the procedure 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 PAM 738-750, DA PAM 738-751, and TB 43-0002-43.
Conservation of Resources. To conserve time and labor, and to avoid evacuation to an intermediate
maintenance activity, unit/detachment commanders may designate, in writing, rigger personnel to accomplish
classification inspection of overage air delivery equipment.
Inspection Function Requirement. Normally, airdrop 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 packing surface 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 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 maintenance function for further
determination of economic repair and repair accomplishment, if applicable.
Parachutes that are deemed unserviceable by a packing or rigging
activity will be rigger-rolled in accordance with WP 0054 00,
