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
