MAINTENANCE ALLOCATION CHART

SECTION

I. Introduction

B.1. MAINTENANCE ALLOCATION CHART.

a. This Maintenance Allocation Chart (MAC) assigns maintenance functions in accordance with the AviationMaintenance concept for Army aviation. These maintenance levels - Unit Maintenance (AVUM), Direct Support(AVIM), and Depot Maintenance - are depicted on the MAC as:

AVUM - corresponds to an O codein the Repair Parts andSpecial Tools List(RPSTL).

AVIM - corresponds to an F codein the Repair Parts andSpecial Tools List(RPSTL).

DEPOT - corresponds to a D code inthe Repair Parts and Spe-cial Tools List (RPSTL).

b. The maintenance to be performed below depot and in the field is described as follows:

(1) Aviation Unit Maintenance (AVUM) activities will be staffed and equipped to perform high frequency9On-Aircraft9 maintenance tasks required to retain or return aircraft systems to a serviceable condition. Themaintenance capability of the AVUM will be governed by the Maintenance Allocation Chart (MAC) and limitedby the amount and complexity of ground support equipment (GSE), facilities required, authorized manningstrength, and critical skills available. The range and quantity of authorized spare modules/components will beconsistent with the mobility requirements dictated by the air mobility concept. (Assignments of Maintenance tasksto divisional company size aviation units will consider the overall maintenance capability of the division, therequirements to conserve personnel and equipment resources, and air mobility requirements.)

(a) Company Size Aviation Units: Perform those tasks which consist primarily of preventive mainte-nance and maintenance repair and replacement functions associated with sustaining a high level of aircraftoperational readiness. Perform maintenance inspections and servicing to include preflight, daily, intermediate,periodic (or phased), and special inspections, as authorized by the MAC or higher headquarters. Identify the causeof equipment/system malfunctions using applicable technical manual troubleshooting instructions, built-in testequipment (BITE), installed aircraft instruments, or test, measurement, and diagnostic equipment (TMDE).Replace worn or damaged modules/components that do not require complex adjustments or system alignment andwhich can be removed/installed with available skills, tools, and ground support equipment. Perform operationaland continuity checks and make minor repairs to the electrical system. Inspect, service, and make operational,capacity, and pressure checks to hydraulic systems. Perform servicing, functional adjustments, and minor repair/replacement to the flight control, propulsion, power train, and fuel systems. Accomplish airframe repair that does

TM 1-6625-735-14

B-1

not require extensive disassembly, jigging, or alignment. The manufacture of airframe parts will be limited tothose items which can be fabricated with tools and equipment found in current air mobile tool and shop sets.Evacuate unserviceable modules/components and end items beyond the repair capability of AVUM to the supportAVIM.

(b) Less than Company size Aviation Units: Aviation elements organic to brigade, group, battalionheadquarters, and detachment size units are normally small and have less than 10 aircraft assigned. Maintenancetasks performed by these units will be those which can be accomplished by the aircraft crew chief or assignedaircraft repairman and will normally be limited to preventive maintenance, inspections, servicing, spot painting,module/component fault diagnosis, and replacement of selected modules/components. Repair functions will nor-mally by accomplished by the support AVIM unit.

(2) Aviation Intermediate Maintenance (AVIM).

(a) Provides Mobile, responsive9One-Stop9maintenance support. (Maintenance functions which are notconducive to sustaining air mobility will be assigned to depot maintenance.)

(b) May perform all maintenance functions authorized to be done at AVUM. Repair of equipment forreturn to user will emphasize support or operational readiness requirements. Authorized maintenance includesreplacement and repair of modules/components and end items which can be accomplished efficiently with avail-able skills, tools, and equipment.

(c) Establishes the Direct Exchange (DX) program for AVUM units by repairing selected items for returnto stock when such repairs cannot be accomplished at the AVUM level.

(d) Inspects, troubleshoots, performs diagnostic test, repairs, adjusts, calibrates, and aligns aircraft systemmodules/components. AVIM units will have capability to determine the serviceability of specified modules/components removed prior to the expiration of the Time Between Overhaul (TBO) or finite life. Module/component disassembly and repair will support the DX program and will normally be limited to tasks requiringcleaning and the replacement of seals, fittings, and items of common hardware. Airframe repair and fabrication ofparts will be limited to those maintenance tasks which can be performed with available tools and test equipment.Unserviceable repairable modules/components and end items which are beyond the capability of AVIM to repairwill be evacuated to Depot Maintenance.

(e) Performs aircraft weight and balance inspections and other special inspections which exceed AVUMcapability.

(f) Provides quick response maintenance support, including aircraft recovery and air evacuation, on-the-job training, and technical assistance through the use of mobile maintenance contact teams.

(g) Maintains authorized operational readiness float aircraft.

(h) Provides collection and classification services for serviceable/unserviceable material.

(i) Operates a cannibalization activity in accordance with AR 750-50. (The aircraft maintenance companywithin the maintenance battalion of a division will perform AVIM functions consistent with air mobility require-ments and conservation of personnel and equipment resources. Additional intermediate maintenance support willbe provided by the supporting nondivisional AVIM unit.)

B.2. USE OF THE MAINTENANCE ALLOCATION CHART (SECTION II.).

NOTE

Approved item names are used throughout this MAC. Generic terms/nomenclatures (if any) areexpressed in parentheses and are not to be considered as official terminology.

a. This Maintenance Allocation Chart assigns maintenance functions to the lowest level of maintenance, basedon past experience and the following considerations:

(1) Skills available.

(2) Work time required.

(3) Tools and test equipment required and/or available.

b. Only the lowest level of maintenance authorized to perform a maintenance function is indicated. If thelowest maintenance level cannot perform all tasks of any single maintenance function (e.g., test, repair), then thehigher maintenance level(s) that can accomplish additional tasks will also be indicated.

c. A maintenance function assigned to a maintenance level will automatically be authorized to be performedat any higher maintenance level.

d. A maintenance function that cannot be performed at the assigned level of maintenance for any reason maybe evacuated to the next higher maintenance level. Higher maintenance levels will perform the maintenancefunctions of lower maintenance levels when required by the commander who has the authority to direct suchtasking.

e. The assignment of a maintenance function will not be construed as authorization to carry the related repairparts or spares in stock. Information to requisition or otherwise secure the necessary repair parts will be asspecified in the associated Repair Parts and Special Tools List (RPSTL).

f. Normally there will be no deviation from the assigned level of maintenance. In cases of operationalnecessity, at the request of a lower maintenance level and on a one-time basis, transfer of maintenance functionsto the lower level may be accomplished by specific authorization of maintenance officer of the higher level ofmaintenance to which the function is assigned. The special tools, equipment, etc., required by the lower level ofmaintenance to perform this function will be furnished by the maintenance level to which the function is assigned.This transfer of a maintenance function to a lower maintenance level does not relieve the higher maintenancelevel of the responsibility for the function. The higher level of maintenance will provide technical supervision andinspection of the function being performed at the lower lever.

B.3. DEFINITIONS.

a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or electricalcharacteristics with established standards through examination (e.g., by sight, sound, or feel).

b. Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteris-tics of an item and comparing those characteristics with prescribed standards.

c. Service. Operations required periodically to keep an item in proper operating condition, i.e., to clean(includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemicalfluids, or gases.

TM 1-6625-735-14

B-3

d. Adjust. To maintain or regulate, within prescribed limits, by bringing into proper or exact position, or bysetting the operating characteristics to specified parameters.

e. Align. To adjust specified variable elements of an item to bring about optimum or desired performance.

f. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or test, mea-suring, and diagnostic equipments used in precision measurements. Consists of comparisons of two instruments,one of which is certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of theinstrument being compared.

g. Remove/Install. To remove and install the same item when required to perform service or other mainte-nance functions. Install may be the act of emplacing, seating, or fixing into position a spare, repair part, or module(component or assembly) in a manner to allow the proper functioning of an equipment or system.

h. Replace. To remove an unserviceable item and install a serviceable counterpart in its place.9Replace9isauthorized by the MAC and assigned maintenance level is shown as the 3d position code of the SMR code.

i. Repair. The application of maintenance services, including fault location/troubleshooting, removal/installation and disassembly/assembly procedures, and maintenance actions to identify troubles and restore ser-viceability to an item by correcting specific damage, fault, malfunction, or failure in a part, subassembly, module(component or assembly), end item, or system.

j. Overhaul. That maintenance effort (service/action) prescribed to restore an item to a completely serviceable/operational condition as required by maintenance standards in appropriate technical publications (i.e., DMWR).Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not normallyreturn an item to like new condition.

k. Rebuild. Those services/actions necessary for the restoration of unserviceable equipment to a like newcondition in accordance with original manufacturing standards. Rebuild is the highest degree of material main-tenance applied to Army equipment/components.

This fine document...

Was brought to you by me:

Liberated Manuals -- free army and government manuals

Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?

I am setting this document FREE. This document was made by the US Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.

I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
