MC1-1B/MC1-1E TROOP BACK PARACHUTE ASSEMBLY
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 MC1-1B/MC1-1E parachute is in proper operating condition, and ready for its
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
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 738-750, DA PAM 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 the 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 shadow 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 facility.
