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
