This maintenance level IS not included in Section II, column (4) of the Maintenance Allocation Chart. Functions to
this level of maintenance are identified by a work-time figure in the "H" column of Section II, column (4), and an
associated reference code is used in the Remarks column (6). This code is keyed to Section IV, Remarks, and
the SRA complete repair application is explained there.
