TM 5-6115-332-14 P-8-614-14 TO 35C2-3-424-1 APPENDIX C MAINTENANCE  ALLOCATION  CHART  (FOR  ARMY  AND  MARINE CORP ONLY) Section I. INTRODUCTION C-1.   General a.  This   section   provides   a   general   explanation   of all  maintenance  and  repair  functions  authorized  at various   maintenance   levels. b.  Section   II   -   designates   overall   responsibility for  the  performance  of  maintenance  functions  on the   identified   end   item   or   component   and   the   work measurement  time  required  to  perform  the  func- tions   by   the   designated   maintenance   level.   The   im- plementation   of   the   maintenance   functions   upon the  end  item  or  component  will  be  consistent  with the   assigned   maintenance   functions. c.  Section  III  -  lists  the  tools  and  test  equipment required  for  each  maintenance  function  as  refer- enced  from  Section  II. C-2.  Explanation  of  Columns  in  Sec- tion H a.  Column  1.  Group   Number.   Column  1  lists group   numbers   to   identify   related   components.   as- semblies,   sub-assemblies,   and   modules   with   their next  higher  assembly.  The  applicable  groups  are listed   in   the   MAC   in   disassembly   sequence   begin- ning  with  the  first  group  removed. b.   Column   2.   Component/Assembly. This   col- umn   contains   the   noun   names   of   components,   as- semblies,   sub-assemblies   and   modules for   which maintenance   is   authorized. c.  Column   3.   Maintenance   Functions. T h i s column   lists   the   functions   to   be   performed   on   the item  listed  in  column  2.  The   maintenance   functions are  defined   as   follows: (1)  Inspect.   To   determine   serviceability   of   an item  by  comparing  its  physical,  mechanical,  and/or electrical  characteristics  with  established  stan- dards   through   examination. (2)  Test.   To  verify  serviceability   and   detect incipient   failure   by   measuring   the   mechanical   or electrical   characteristics   of   an   item   and   comparing those   characteristics   with   prescribed   standards. (3)  Service.  Operating   required   periodically to  keep  an  item  in  proper  operating  condition,  i.e.,  to clean   (decontaminated),   to   preserve,   to   drain,   to paint,   or   to   replenish   fuel,   lubricants,   hydraulic   flu- ids,   or   compressed   air   supplies. (4)  Adjust.  T O  maintain   within   prescribed limits,   by   bringing   into   proper   or   exact   position,   or by  setting  the  operating  characteristics  to  specified parameters. (5)  Align.   To   adjust   specified   variable   ele- ments  of  an  item  to  bring  about  optimum  or  desired performance. (6)  Calibrate.  T O  determine   and   cause   cor- rections  to  be  made  or  to  be  adjusted  on  instruments or   test   measuring   and   diagnostic   equipments   used in   precision   measurement.   Consists   of   comparison of  two  instruments,  one  of  which  is  a  certified  stan- dard   of   known   accuracy,   to   detect   and   adjust   any discrepancy   in   the   accuracy   of   the   instrument   being compared. (7)  Install.   The  act  of  emplacing,  seating,  or fixing   into   position   an   item,   part   of   module   (com- ponent  or  assembly)  in  a  manner  to  allow  the  proper functioning  of  an  equipment  or  system. (8)  Replace. The   act   of   substituting   a   ser- viceable   like   type   part,   sub-  assembly,    or    module (component or    assembly)    for    an unserviceable counterpart. C-1
