program  within  his/her  geographical  areas.  This representative also makes recommendations to the AMMRL program manager about changes to overall management and operational policies and procedures. They schedule, prepare, and maintain IMRLs for all applicable  Navy  aircraft  maintenance  activities; obtain accountable in-use inventory reports from all activities  under  assigned  geographical  areas,  and forward a quarterly inventory report to the ASO. They also update the SERMIS, various IMRLs, and asset reports regularly or as requested by activities in the chain of command. Support  Equipment  Controlling  Authority (SECA).  SECAs are major aviation commands that exercise administrative control of AMMRL program SE end items for allowance and inventory control. The following is a list of designated SECAs: Commander,   Naval   Air   Force,   Atlantic (COMNAVAIRLANT) Commander,  Naval  Air  Force,  Pacific (COMNAVAIRPAC) Chief  of  Naval  Air  Training  (CNATRA) Commander,   Naval   Air   Reserve   Force (COMNAVAIRESFOR) Commander,  Naval  Air  Systems  Command (COMNAVAIRSYSCOM) Naval  Air  Maintenance  Training  Group (NAMTRAGRU) Commanders,   Fleet   Air   (COMFAIR). COMFAIRs   represent   the   SECA   within   their geographical areas of responsibility. Aircraft   Maintenance   Activities.  These activities   are   responsible   for   the   operation, maintenance, review, and submission of requests for revision of the IMRL. They also hold the annual inventory and ensure that required custody cards are on hand. Q17. 018. What two instructions describe the procedures for allowance and inventory of the AMMRL program? How   is   Naval   Air   Systems   Command (NAVAIRSYSCOM) involved in the AMMRL program? INDIVIDUAL MATERIAL READINESS LIST (IMRL) LEARNING   OBJECTIVE:   Describe   the sections  of  the  Individual  Material  Readiness List (IMRL) and their purposes. The IMRL is constructed for Navy and Marine Corps  aviation  maintenance  activities  by  extracting applicable   portions   of   SERMIS   data.   Physical inventories and IMRL transaction reports are the basis for the on-hand quantity listed in the IMRL. This data determines the material supportability for each IMRL activity. The data is also consolidated to produce functional  wing,  SECA,  and  Navywide  listings. IMRLs identify material requirements and provide a basis for SE procurement. This information aids in decisions   on   overall   readiness   posture,   budget forecasts, equipment procurement, and redistribution of assets. The IMRL serves as the allowance and inventory management list for SE end items. IMRLs identify material  requirements  and  provide  a  measure  of supportability  of  aviation  maintenance  by  identifying authorized SE allowances and providing inventory data. Inventory records within the SERMIS data base provide  information  used  to  determine  the  total inventory  quantities.  ASO  also  uses  the  IMRL inventory  and  authorized  allowance  data  to  develop the Aviation Consolidated Allowance List (AVCAL) and  Shore  Based  Consolidated  Allowance  List (SHORECAL) for piece part support of SE end items. The IMRL has five major sections: employment data, change list, index, main body, and the activity inventory record. An IMRL legend introduces every IMRL. The legend lists all SERMIS data elements printed in the IMRL with the headings as they appear. A general description of the major IMRL sections with an   explanation   of   their   contents   and   related terminology are as follows: Employment data section. This section gives the activity the list of the employment data used to create that IMRL. This list allows the activity to see the data used to calculate the allowances shown in their IMRL. Change list section. This section is a listing of all the changes to an activity’s IMRL since the printing of the previous IMRL. An update action code shows additions, deletions, or changes that affect an activity. Index  section.  This  section  has  six  parts  or cross-references. The six cross-references are part 3-16
