Scope This manual lists spares and repair parts; special tools; special test, measurement, and diagnostic equipment (TMD

33、E), and other special support equip- ment required for performance of direct support, and general support maintenance of the AN/GRC106. It authorizes the requisitioning and issue of spares and repair parts as indicated by the source and maintenance codes. 2. General This Repair Parts and Special Too

34、ls List is divided into the following sections: a. Section II. Repair Parts List. A list of spares and repair parts authorized for use in the perfor- mance of maintenance. The list also includes parts which must be removed for replacement of the authorized parts. Parts lists are composed of func- ti

35、onal groups in numeric sequence, with the parts in each group listed in figure and item number se- quence. b. Section III. Special Tools List. Not applicable. c. Section IV. National Stock Number and Part Number Index. A list, in National item identification number (NIIN) sequence, of all National s

36、tock numbers (NSN) appearing in the listings, followed by a list, in alphameric sequence, of all part numbers appearing in the listings. National stock numbers and part numbers are cross-referenced to each illustra- tion figure and item number appearance. 3. Explanation of Columns a. Illustration. T

37、his column is divided as follows: (1) Figure number. Indicates the figure number of the illustration on which the item is shown. (2) Item number. The number used to identify item called out in the illustration. b. Source, Maintenance, and Recoverability (SMR) Codes. (1) Source code. Source codes ind

38、icate the manner of acquiring support items for maintenance, repair, or overhaul of end items. Source codes are entered in the first and second positions of the Uniform SMR Code format as follows: CodeDefinition PA Item procured and stocked for anticipated or known usage. XA Item is not procured or

39、stocked because the requirements for the item will result in the replacement of the next higher assembly. XD A support item that is not stocked.

Maintenance codes are assigned to indicate the levels of maintenance authorized to USE and REPAIR support items. The maintenance codes are entered in the third and fourth positions of

41、 the Uniform SMR Code format as follows: (a) The maintenance code entered in the third position will indicate the lowest maintenance level authorized to remove, replace, and use the support item. The maintenance code entered in the third posi- tion will indicate one of the following levels of mainte
