TM 10-4610-246-13 APPENDIX B MAINTENANCE ALLOCATION CHART (MAC) Section I INTRODUCTION B.1 The Army Maintenance System MAC. a. This introduction (section I) provides a general explanation of all maintenance and repair functions authorized at various maintenance levels under the standard Army Maintenance System concept. b. The Maintenance Allocation Chart (MAC) in section  II  designates  overall  authority  and  responsibility  for  the performance  of  maintenance  functions  on  the  identified  end  item  or  component.  The  application  of  the  maintenance functions   to   the   end   item   or   component   will   be   consistent   with   the   capacities   and   capabilities   of   the   designated maintenance levels, which are shown on the MAC in column (4) as: Unit - includes two subcolumns, C (operator/crew) and O (unit) maintenance. Direct Support - includes an F subcolumn. General Support - includes an H subcolumn. Depot - includes a D subcolumn. c. Section  III  lists  the  tools  and  test  equipment  (both  special  tools  and  common  tool  sets)  required  for  each maintenance function as referenced from section II. d. Section IV contains supplemental instructions and explanatory notes for a particular maintenance function. B-2 Maintenance Functions. Maintenance functions are limited to and defined as follows: a. Inspect.  To  determine  the  serviceability  of  an  item  by  comparing  its  physical,  mechanical,  and/or  electrical characteristics 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 characteristics 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, chemical fluids, or gases. d. Adjust.  To  maintain  or  regulate,  within  prescribed  limits,  by  bringing  into  proper  position,  or  by  setting  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, measuring, and diagnostic equipment used in precision measurement. Consists of comparisons of two instruments, one  of  which  is  a  certified  standard  of  known  accuracy,  to  detect  and  adjust  any  discrepancy  in  the  accuracy  of  the instrument being compared. g. Remove/Install.         To   remove   and   install   the   same   item   when   required   to   perform   service   or   other maintenance 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.
