What publication is the primary index for req- uisitioning   all   Navy   publications,   forms, technical directives, and departmental directives Q6. stocked  at  the  Defense  Distribution  Depot Susquehanna Pennsylvania (DDSP)? What publication contains a listing of published and  distributed  NAVAIR  technical  directives  as they apply to a particular aircraft? TECHNICAL DIRECTIVES LEARNING OBJECTIVES: Identify the purpose, types, and categories of the technical directives. Describe the methods for updating technical directives. Technical  directives  (TDs)  are  letter-  and message-type directives that direct modifications and onetime  inspections  of  weapons  systems  and equipment. In addition, TDs provide the technical information necessary to properly inspect or alter the configuration   of   aircraft,   engines,   systems,   or equipment. The TD system is the only authorized method   for   directing   the   accomplishment   and recording of modification and onetime inspections of NAVAIR equipment. The Naval Air System Command Technical Directive System, NAVAIR 00-25-300, contains the policies and procedures that govern the TD system. TDs are used for the following purposes: Authorize and direct incorporation of approved retrofit changes Issue  directions  for  onetime  inspections  or precautionary  instructions  regarding  personnel safety  and  equipment  limitations Provide  detailed  instructions  necessary  to perform inspections or install retrofit changes and to report and record compliance Provide  an  official  record  of  inspections  and retrofit  changes  for  purposes  of  technical directive status accounting Respond quickly to safety or urgent operational requirements to incorporate retrofit changes Expeditiously  implement  minor  changes requested by the fleet There are four types of TDs as follows: Formal Change TD. A formal change TD is the primary document for implementing a configuration change.  The  formal  change  TD  provides  the information that is needed to make the change and to record  that  the  change  was  completed.  A  formal change TD directs the addition, deletion, removal, 3-7
