principles of maintenance
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
function concept and objective of tamms
Function, Concept, and Objective of TAMMS
  • Function: provide DA & commanders with info - effectiveness of maint policies, procedures and actions
  • Concept: record essential data concerning equipment operations
  • Objective: record minimum data, but essential data for control, operation & maint at each level of command

purpose of readiness reporting
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
individual responsibilities for readiness reporting
Individual Responsibilities for Readiness Reporting
  • Operator PMCS: operator responsible to notify maint activity of repairs identified
  • Repairer: maintain 314
  • DA 2406: definitions, reportable equipment, responsibilities, distribution, and procedures listed in AR 700-138
