cancelled. A TD that is issued with no completion date
should be removed from your active files after a
cancellation amendment has been issued. A completed
TD is retained (not discarded) as a permanent record of
system configuration at the designated compliance
maintenance level. An unincorporated TD that is
beyond its completion date does not relieve the
maintenance responsibility for compliance.
Supersedure is the administrative process by which
an issued TD is removed from active files. An interim
TD is superseded by a formal change TD. A TD
revision supersedes the basic TD, including all
previously issued amendments and revisions.
Cancellation terminates compliance requirements
and removes a TD from active files. A cancelled TD
may be discarded. A TD cancellation is usually issued
as a TD amendment. Cancellation amendments specify
disposition of prior compliance.
TECHNICAL DIRECTIVE NUMBERING
The TD control center at NATEC assigns TD
numbers by using one of two systems. The first
numbering system is to number the TD sequentially by
title; for example, Avionics Change (AVC) 3500,
which would be the 3,500th avionics change. The
second system is to number the TD sequentially by title
within a specified type/model of equipment; for
example, F-18 Airframe Change (AFC) 45, which
would be the 45th airframe change to the F-18 airframe.
Some of the most common technical directives in TD
code sequence are listed in table 3-1. For a complete
list, refer to NAVAIR 00-25-100, WP 009 00.
Upon receipt of a new TD, the CTPL librarian
stamps the TD with the CTPL stamp and routes a copy
of the TD to quality assurance (QA) for review of TD
applicability. The CTPL librarian should ensure that
the required TD and its revisions and amendments are
routed to a quality assurance representative (QAR) for
Next, the librarian delivers a copy of the TD,
determined to be applicable by QA, along with a TD
routing and tracking sheet, part 1, (fig. 3-4) to
maintenance control for action. Maintenance control
completes part 1, item 3, of the tracking sheet and
routes parts 1 and 2 to QA.
Logs and records will add the TD to the
NALCOMIS TD configuration file and initiate a
maintenance action form (MAF) for each TD that QA
determines to be required. Logs and records should
also annotate the incorporation compliance and the
event on the MAF; for example, incorporation no later
than next phase or not later than next 10 flight hours.
When compliance involves an aircraft, engine, or
component, logs and records will annotate the current
time plus the compliance time as the maximum time
until the aircraft or item is restricted from flight. Logs
and Records also orders the required TD parts or kits
and ensures that the TD routing and tracking, part 2,
(fig. 3-5) is signed or initialed by a QAR before the TD
is logged in the appropriate logbook as not being
appropriate. Logs and Records also adds the new TD to
TDSA List No. 02 if the TD is an AFC or AFB.
