B-5. MAINTENANCE CATEGORIES AND WORK TIMES. The maintenance

categories (levels) AVUM, AVIM and DEPOT are listed on the

Maintenance Allocation Chart with individual columns that indicate

the work times for maintenance functions at each maintenance level.

Work time presentations such as 0.1 indicate the average time it

requires a maintenance level to perform a specified maintenance

function. If a work time has not been established, the columnar

presentation shall indicate "-.-". Maintenance levels higher than

the level of maintenance indicated are authorized to perform the

indicated function.

B-6. TOOLS AND TEST EQUIPMENT (Section III). Common tool sets (not

individual tools), special tools, test and support equipment

required to perform maintenance functions are listed alphabetically

with a reference number to permit cross-referencing to column 5 in

the MAC. In addition, the maintenance category authorized to use

the device is listed along with the item National Stock Number

(NSN) and, if applicable, the tool number to aid in identifying the

tool/device.
