Standard type of tools, such as screwdrivers, pliers, shall not be listed. When a contractor
21、 cannot obtain an approved list, the manual shall show the contractors recomended special tools and test equipment. However, these recommendations shall be changed promptly, if necessary, to conform to the official Government list as soon as such information is provided to the contractor. 3.3.3.1 Sp

23、identical, they shall be presented only once. b. When swlar, but not completely identical jobs are being covered for more than one physical area, complete and separate instructions may be made for each area so that maintenance personnel are not required to refer to more than one place in the manual
24、to complete a single job. the presentation of identical information shall, insofar as possible, use identical headings, words, tables and illustrations, In such cases, c. An exception to the requirement for separate coverage by areas called for in b above, shall be made when the procedures and equip
