A CTPL librarian should not duplicate a TD, but he or she must maintain positive control. To do this, the librarian should annotate page 1 of the master copy of the TD as to the location of other copies of the TD. When the TD is returned, the CTPL librarian should dispose of it in accordance with local procedures and annotate the master copy as to its location and status. Upon receipt of the Weekly Summary of Issued Technical  Directives,  the  CTPL  librarian  should  review the summary for TDs that have been issued and are required to be acted upon by his or her activity but have not been received. After verifying and resolving any discrepancies in this summary, the librarian retains the summary for reference as well as for use during the audit of the CTPL. REQUISITIONING PRINTED TECHNICAL DIRECTIVES TDs  are  requisitioned  in  accordance  with procedures outlined in NAVAIR 00-25-100, Work Package (WP) 017 00. Formal or hard copy TDs are stored at Defense Distribution Depot Susquehanna Pennsylvania.  TDs  stored  at  this  depot  are stock-numbered items and are listed in NAVSUP PUB 2002.  NAVSUP  PUB  2002  contains  the  information  to identify and requisition individual TDs. To requisition TDs, you should use one of the military standard requisition  and  issue  procedure  (MILSTRIP)  methods. The  technical  publication  library  (TPL)  is  a centrally  managed  function  under  the  quality  assurance division of an aviation maintenance department. Based on activity organization, there are normally two types of  libraries  within  an  aviation  maintenance organization. If more than one library is required to meet the needs of an aviation maintenance department, a central library is established to manage the overall distribution  of  technical  information.  When  one  library is designated as the central library, all other libraries are designated as dispersed libraries. Dispersed libraries are  located  in  individual  work  centers  and  are responsible for storing and making available to their users the technical documents for the equipment under their cognizance. The central library is responsible for the   initial   outfitting   of   the   dispersed   libraries. Additionally, all requests for additional publications are made through the central library. You should refer to Naval Air Systems Command Technical Manual Program, NAVAIR 00-25-100, and the Naval Air Technical  Data  and  Engineering  Service  Command (NATEC)   Technical   Publication   Library   (TPL) If a TD cannot be obtained from NATEC, another squadron, or a supporting IMA, request the TD from cognizant  wing  via  message  with  the  aircraft controlling custodian, type commander, and support equipment  controlling  authority  (ACC/TYCOM/ SECA) as information addressees. program  for  detailed  technical  library  establishment and operating procedures.

Q9.    After amendment C has been applied to a tech- nical directive, what action must occur if the TD is to be further changed? Q1O.   What process is used to remove a technical dir- ective (TD) from the active files? Q11.   What  information  summary  contains  a  weekly  list of technical directives (TDs) that have been issued? 3-13 revisions for the central technical publication library (CTPL) and dispersed libraries. The TPL program software  provides  for  updating  the  automatic distribution requirements listing (ADRL), maintaining a dead file of publications no longer held in the CTPL, printing change entry certification records (CECRs), and  maintaining  a  CECR  tickler  file.  Detailed operating  instructions  are  contained  in  “Library Operating Procedures” in the main menu of the TPL program and in NAVAIR 00-25-100.
