Maintenance Operations
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
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)
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 (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 (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
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)
Estimate the cost of repair:
Direct labor
Direct materials
Indirect or overhead costs
Contractual services
shipping costs
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: 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)
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 (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
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)
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 (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 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)
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
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)
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 (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)
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 (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: 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
Basic Types of Records used in DA PAM 738-750
Operational records: provide for control of operators & equipment, Examples:
Motor Vehicle Utilization Record (DD Form 1970) control use of equip
Organizational Control Record for Equipment (DA Form 2401) identify where equip is
Instructions found in Chapter 2, DA PAM 738-750
Basic Types of Records used in DA PAM 738-750 (cont)
Maintenance Records: used to control maintenance Example:
Exchange tag (DA Form 2402) identify warranty claims & equip improvement
Equipment Inspection and Maintenance Worksheet (DA Form 2404) identify equip faults during operator maint
Preventive Maintenance Schedule and Record (DD Form 314)
Chapter 5, DA PAM 738-750
Equipment Historical Record
Permanent record with info on receipt, operation, maint, modification, transfer & disposal of equipment
Examples:
Log Book Binder-consolidate historical records
Equipment Record Folder-appropriate TAMMS forms
DA Form 2408 Series-historical record
DA Form 2407-Maintenance Request
Mission Capability
FMC: can perform combat mission
NMC: cannot perform combat mission – faults in NOT AVAILABLE/ READY if column of PMCS checklist, outstanding Urgent or limited urgent MWO, Unit commander judges equip not to be safe or able to perform combat mission
Mission Capability (cont)
NMCM: NMC because of maint is being performed:
2406 broken into organic or support
NMCM time recorded on back of 314
NMCS: NMC because of supply
2406 broken into organic or support
NMCS time recorded on back of 314
Mission Capability (cont)
Available Time: # of days that equip is on hand in FMC condition
Possible Time: # of days equip is on hand during reporting period
day item is gained is counted as day
day item is lost is not counted as day
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
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
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
