TM 5-5420-209-12APPENDIX BMAINTENANCE ALLOCATION CHARTB-1.Maintenance Allocationthe Three Level Maintenance ConceptSection I. INTRODUCTIONChart (MAC). This MAC assigns maintenance functions in accordance withAllocation Chart, Section II.B-2.Use of the Maintenancea. The MAC assigns maintenance functions based on the following considerations:(1) Skills available.(2) Work time required.(3) Tools and test equipment required and/or available.b. If a lower level of maintenance identified in column (4) of the MAC cannot perform all tasks of a single maintenancefunction (e.g., test, repair), then the higher level that can perform other tasks of that function is also indicated.c. Higher maintenance levels are automatically authorized to perform maintenance functions assigned to a lowermaintenance level.d. Higher maintenance levels will perform the maintenance functions of lower maintenance levels when required ordirected by the Commander who has authority to direct such tasking.e. Assignment of a maintenance function in the MAC does not carry automatic authorization to carry the relatedspare or repair parts in stock. Information to requisition or secure parts will be as specified in the associated RPSTL.f. Normally, there will be no deviation from the assigned level of maintenance. However, in cases of operationalnecessity, maintenance functions assigned a higher level may, at the request of the lower level, be assigned to the lowerlevel on a one-time basis, if specifically authorized by the maintenance officer of the higher level to which the function isassigned. In such a case, the special tools, equipment, etc., required by the lower level to perform this function will befurnished by the higher level assigned the function. Also, transfer of a function to a lower level does not relieve the higherlevel of responsibility for the function, so the higher level will provide technical supervision and inspection of the functionbeing performed at the lower level.B-3.Maintenance Functions. Maintenance functions will be limited to and defined as follows.a. Inspect.To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical charac-teristics with established standards through examination (e.g., by sight, sound, or feel).b. Test.To verify serviceability and detect incipient failure by measuring the mechanical or electrical characteristicsof an item and comparing those characteristics with prescribed standards.B-1
