MAINTENANCE ALLOCATION CHART

Section I. INTRODUCTION

GENERAL

This Maintenance Allocation Chart (MAC) designates responsibility for performance of maintenance repair functions

at specified maintenance levels.

Section I is a general explanation and definition of terms.

Section II shows the maintenance level responsible and estimated work measurement time for specific functions.

Section III lists common tool sets and the special tools, test, and support equipment required for each maintenance

function shown in Section II.

Section IV lists the remarks referenced in Section II.

EXPLANATION OF COLUMNS IN SECTION II

Column 1, Group Number. Column 1 lists group numbers, the purpose of which is to identify components,

assemblies, subassemblies, and modules with the next higher assembly.

Column 2, Component/Assembly.

Column 2 contains the noun names of components, assemblies,

subassemblies, and modules for which maintenance is authorized.

Column 3, Maintenance Function. Column 3 lists the functions to be performed on the item listed in Column 2.

Column 4, Maintenance Level. Column 4 specifies, by the listing of a "work time" figure in the appropriate

subcolumn(s), the level of maintenance authorized to perform the function listed in Column 3. This figure represents the

active time required to perform that maintenance function at the indicated level of maintenance. If the number or level of

the tasks within the listed maintenance function vary at different maintenance levels, appropriate work time figures will be

shown for each level. The number of man-hours specified by the work time figure represents the average time required to

restore an item (assembly, subassembly, component, module, end item, or system) to a serviceable condition under

typical field operating conditions. This time includes preparation time, troubleshooting time, and quality assurance/quality

control time in addition to the time required to perform the specific tasks identified for the maintenance functions

authorized in the MAC. This figure does not include any time for performance of preliminary tasks listed elsewhere in the

MAC; e.g., removal of engine under repair of fuel pump,
