SDLM, conversion, modification, modernization,
and ASPA inspections performed on the aircraft
by an overhaul activity or commercial contractor.
When an aircraft is transferred to a NAV-
AVNDEPOT or contractor activity for rework,
the aircraft logbook accompanies the aircraft and
is brought up to date as necessary by the activity
performing the work. This applies even though
there is no change in reporting custodian (fig. 6-5).
This record is permanently retained.
Technical Directives (OPNAV 4790/24A)
Technical Directives forms, which make up the
technical directives section of the logbook, contain
records of all NAVAIR technical directives (TDs)
affecting the airframe structure and its integral
parts. A separate form is used for each type of
directive in this section.
The system for recording TD data is called the
Technical Directive Status Accounting (TDSA)
system. Technical directive requirements lists
Nos. 02 and 04 are prepared and distributed to
reporting custodians by the Naval Aviation
Maintenance Office (NAVAVNMAINTOFF),
which is the TDSA program manager. List No.
02 contains a listing of directives applicable to a
specific bureau number, but not incorporated;
and list No. 04 contains a listing of directives
applicable to a specific bureau number and
reported as incorporated. Lists Nos. 02 and 04
are distributed to activities on a quarterly basis.
Since these listings reflect applicable TDs, it is not
necessary to add TDs to the lists that are not
Lists Nos. 02 and 04 should be inserted in the
technical directive section of the aircraft logbook,
with list No. 02 preceding list No. 04. You should
refer to the latest editions of OPNAVINST 4790.2
and NAVAIR 00-25-300 for a more detailed
explanation of the TDSA system.
Upon receipt of the initial lists Nos. 02 and
04 of the same date, you should remove Technical
Directives forms from the logbook; and after
verification against the new lists, retain or destroy
them at the direction of the reporting custodian.
