Maintenance Operations


Principles of maintenance l.jpg

Principles of Maintenance

  • Maintenance performed at level best qualified, responsive & cost effective

  • IAW MAC chart

  • Repairs beyond organic capability delivered to next level

  • Unit level performed before evacuated

  • Controlled exchange used to support maintenance


Levels of maintenance l.jpg

Levels of Maintenance

  • Unit Maintenance: Maintenance which an organization has authorization & responsibility to perform on its own equipment.

  • Subdivided into:

    • first level (operator)

    • second level (trained maint. personnel)


Levels of maintenance cont l.jpg

Levels of Maintenance (cont)

  • Direct support: performed by TOE or TDA units responsible for DS

  • “return to user basis”

  • Technical assistance to unit maintenance elements

  • Repairable exchange of serviceable items for unserviceable


Levels of maintenance cont5 l.jpg

Levels of Maintenance (cont)

  • General support: maintenance support provided on an area basis

  • Overhaul at this level

  • Equipment repaired returned to supply system

  • “return to user” beyond DS

  • Repair part stocked for GS maint


Levels of maintenance cont6 l.jpg

Levels of Maintenance (cont)

  • Depot: performed by TDA industrial activities or Commercial contracts

  • Rebuild beyond GS capability

  • Workload programmed & budgeted annually by wholesale level

  • Rebuilt materiel returned to wholesale supply system


Evacuation repair eligibility of materiel l.jpg

Evacuation & Repair Eligibility of Materiel

  • Maintenance beyond units capability evacuated to next higher level

  • TI done before evacuation:

    • to determine extent of repairs

    • classify item as economically uneconomically repairable

    • detemine if condition was from other than normal wear or combat damage.


Evacuation repair eligibility of materiel cont l.jpg

Evacuation & Repair Eligibility of Materiel (cont)

  • Estimate the cost of repair:

    • Direct labor

    • Direct materials

    • Indirect or overhead costs

    • Contractual services

    • shipping costs


Evacuation repair eligibility of materiel cont9 l.jpg

Evacuation & Repair Eligibility of Materiel (cont)

  • Condition codes used to classify equipment:

    • A - serviceable (without qualifications)

    • B - serviceable (with qualifications)

    • F - unserviceable (repairable)

    • G - unserviceable (incomplete)

    • H - unserviceable (condemned)


Pll definitions l.jpg

PLL Definitions

  • PLL: list of authorized repair parts to be on-hand or on order

    • support daily maint operations for a prescribed number of days

    • demand supported, non-demand supported, and initial stocked items

    • managed by AR 40-61, DA PAM 710-2-1


Pll definitions cont l.jpg

PLL Definitions (cont)

  • Initial Fielding List (IFL): support kits developed and fielded concurrently with DEPMEDS

    • managed individually by TAMMIS or DA Form 3318, Record of Demands

    • retention for 2 years without being demand support (can be extended by authorization from USAMMA)


Pll definitions cont12 l.jpg

PLL Definitions (cont)

  • Combat PLL: parts stocked for unit maint in combat/prescribed # of days

  • Mandatory Parts List (MPL): minimum stockage essential for use during wartime

    • published in TB 8-6500-MPL

    • TOE units with organic maintenance must stock MPL

    • D & D+60 Guard & Reserve also


Items authorized for pll combat pll stockage l.jpg

Items Authorized for PLL/Combat PLL Stockage

  • PLL consists of:

    • items & quantities designated as initial stockage

    • demand supported items control period

    • Active - 180 days, USAR - 360 days

    • Other non-demanded supported items when authorized by 1st general officer in chain of command


Items authorized for pll combat pll stockage cont l.jpg

Items Authorized for PLL & Combat PLL Stockage (cont)

  • PLL consists of: (cont)

    • parts for commercially designed equipment based on local experience

    • if authorized to perform next level maintenance may contain those

    • Basic Issue Items (BII) parts packed with equipment


Items authorized for pll combat pll stockage cont15 l.jpg

Items Authorized for PLL & Combat PLL Stockage (cont)

  • Combat PLL consist of items & quantities prescribed by MPLs

  • Items consumed in maintenance (bench stock):

    • ordered & stocked on usage basis

    • stocked 7 days supply

    • no PLL records required unless part of PLL basic load


Initial stockage of pll l.jpg

Initial Stockage of PLL

  • Initial stockage level determined by

    • U.S. Army Materiel Readiness Support Activity (USAMRSA)

    • U.S. Army Medical Materiel Agency (USAMMA)

  • Guidance for requesting assistance in paragraph 8-5, Chapter 8, of DA Pam 710-2-1


Initial stockage of pll cont l.jpg

Initial Stockage of PLL (cont)

  • Upon receipt of PLL data:

    • prepare & process DA Form 2063-R

    • prepare a DA Form 3318 for each line authorized for stockage. Use stockage code “MS”

    • request initial stockage of PLL


Non stocked item demand file l.jpg

Non-Stocked Item Demand File

  • Definition: separate file of DA Form 3318s used to record demands for parts not part of unit’s PLL to determine if parts should be stocked

  • Items must meet stockage criteria:

    • 3 demands in most recent 180 days

    • 3 demands in most recent 360 days


Non stocked item demand file cont l.jpg

Non-Stocked Item Demand File (cont)

  • Items meet criteria can be moved DS

    • Unit commander decides to stock

    • if added, use ACWT for stockage level

    • prepare DA Form 3318

      • file 3318 in PLL file, at to 2063-R, order

    • if not added, write “Commander does not desire to stock this item” continue to track


Non stocked item demand file cont20 l.jpg

Non-Stocked Item Demand File (cont)

  • Maintenance of 3318:

    • 1st demand prepare 3318, post demand, order item & record request on 2063-R, file in NIIN sequence

    • 2nd & subsequent demands, post demand to 3318, line out demands out side of control period, review to see if item qualifies for DS


Authorized stockage list asl l.jpg

Authorized Stockage List (ASL)

  • MEDLOG Battalions operating under AR 40-61 as SSAs will provide Class VIII to all TOE units in their area

  • Re-supply of Class VIII will sustain essential maint operations

  • ASL shows items that are proven to be sufficiently active to warrant stockage regardless of demand


Authorized stockage list asl22 l.jpg

Authorized Stockage List (ASL)

  • ASL managed in a stock record account to show receipt, issue, and asset status of materiel

  • Repair parts stocked to re-supply unit level requirements & for MEDLOG’s organizational mission

    • NMCS time recorded on back of 314


Mission capability cont29 l.jpg

    • day item is gained is counted as day

    • day item is lost is not counted as day


Mission capability cont30 l.jpg

Mission Capability (cont)

  • Deficiency: defect that makes item, system, subsystem inoperable(NMC)

  • Shortcoming: fault requires maint supply action, does not make (NMC)


Purpose of readiness reporting l.jpg

Purpose of Readiness Reporting

  • Readiness determined by reporting actual status to established standard

  • Deficiences identified to detemine MC & time frame to achieve

  • Deficiences corrected by repair, redistribution, substitution, replenishment, or modernization within budget constraints
