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.

Network-capable, menu-driven TPL computer software tracks current manuals, changes, and The NATEC technical publication library (TPL) program is used in Navy activities to manage the Technical Publication Library program Q8.   What type of change should be used to cancel an existing technical directive? 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.
