LEGEND AND EXPLANATION OF SYMBOLS USED IN REPORT 4760-1
1. Each activity will enter in the applicable column the appropriate symbol to indicate status, position, priority,
responsibility or authorization for each item.
2. Extra pages shall be added to the package as necessary to provide history, results of investigations or comments
to clarify the position or the item itself.
3. The action taken for each item in each of the columns from the "N/S Action" column through the "PSA" column
will be an integrated action by all concerned following INSURV CT/AT, GMI/FCT, and PSA related conferences.
4. The following is a brief description of the purpose of each column:
a. Column "N/S Action" - Indicates Ship Program Manager assignment of responsibility. No government
SCN funded work is authorized in this column. Authorization of work will be as stated under the
"PSA" column for each line item in the work package.
b. Column "K" - Column "K" is used to indicate the position of the shipbuilder for an item indicated in
column "N/S Action" as being the responsibility of the shipbuilder to correct. The shipbuilder may
prepare insert pages for comments as appropriate. A rationale is to be provided for all items not
accepted (marked "KZ") by the shipbuilder.
c. Column "SOS" - This column is used to indicate the position of the Supervising Authority for each of
the items as feasible but especially for those items on which the shipbuilder has responded in column
"K".
d. Column "Ship" - This column is used by the ship to indicate the status or action desired for each item
still considered open, including a priority assignment regardless of the responsibility/action indicated by
INSURV or assigned by the Ship Program Manager or reported corrected by the Supervising Authority.
Comments from Ship's Force providing further information and clarification as insert pages are
especially helpful in planning correction of any item.
e. Column "TY" - This column indicates the position of the TYCOM on the priority assignment of the
ship.
f. Column "PSA" - This column is used by NAVSEA. Authorization of SCN funded work appears only
in this column.
