An entry is made for items A through H, and
M, on each XRAY message submitted to the
CNO. All XRAYS submitted that contain item L
will include CNO as an information addressee.
Entries are made for all other items as the
situation requires. If certain items are not
required, they are not listed.
An explanation of the XRAY message is
contained in the following paragraphs. As you
read this section, refer to the format.
The FROM, TO, INFO, and SUBJ lines make
up the heading of the report. The name of the
activity originating the message is entered on the
FROM line. The name of the primary addressee
or the activity to which the report is sent is entered
on the TO line. The primary addressee is normally
the controlling custodian. The names of informa-
tion addressees are entered on the INFO line.
These include those activities with a need to know
of the reportable action. The SUBJ line contains
five items of information, listed in a particular
NOTE: Items in the subject line that are
enclosed in parentheses will vary with different
the items enclosed in
quotation marks will be present in every report.
First, the abbreviated name of the controlling
custodian of the aircraft being reported is entered.
The next item is the word XRAY. The third part
of this line is the abbreviated name of the
reporting custodian and detachment number, if
applicable, of the aircraft being reported. Next,
the serial number of the XRAY message is
entered, and then the report symbol. A typical
subject line would read as shown below.
LANT XRAY VP-5 099 5442-1
Item Abureau number. The bureau number
of the aircraft being reported is entered here. This
is important because the bureau number is the
only single identification that is different for every
aircraft in the Navy, regardless of type or model.
The CNO maintains and controls the master
BUNO register to ensure that a data number, once
assigned for use with a production contract, is
never reused. The accountability of the aircraft
depends upon the bureau number.
Item Bpermanent unit code. The six-digit
permanent unit code (PUC) representing the
reporting custodian of the aircraft being reported
is entered here. Each reporting custodian of
aircraft has been assigned a permanent unit code
by the Chief of Naval Operations, or, in the case
of detachments, by the controlling custodian. The
assignment of a PUC to a new reporting custodian
is also controlled by CNO. This code will never
change regardless of any change of location,
organization, or mission that a particular activity
may undergo. Except in the case of detachments,
a permanent unit code is never used again
once the unit to which it was assigned has
been decommissioned. A detachment may be
reassigned the same permanent unit code each
time it is formed as long as the designation
remains the same, and it is deployed to the same
ship or station. For example, HC-12, Det 69, with
PUC 999999 could be created and inactivated any
number of times provided the regular location of
deployment (for example, CV-69) was the same.
PUC number 999999 could not be assigned to any
unit other than HC-12, Det 69.
Item Cdate of action. The month, day, and
year of the action reported are entered here. The
month is expressed first as a two-digit number;
and finally, the year using the last two digits. For
example, 21 March 1986 would be reported as
Item Daction code. One of the 12 action
codes previously discussed and listed in table 6-2
is entered as item D. The action code describes
the particular action being reported. Action codes
used for reporting a change in either reporting or
controlling custody are A, F, G, R, and Y. Action
codes used for reporting other than a change in
custody are E, H, M, S, and X.
Item Estatus code. Reported under item E
is the new status code into which the XRAY action
moves the aircraft. If the action being reported
does not involve a change in status, the current
applicable status code is entered. A status code
describes the aircraft. Table 6-4 gives a listing of
permissible action code/status code combinations.
After selection of a status code, the action
code/status code combinations table found in the
governing instruction should be consulted. If the
combinations selected do not agree with the table,
an error has probably been made and another
selection is required. Extreme care is required in
the selection of the status code.
Item Fmodel designation. The full and
complete model designation of the aircraft being
reported is entered h&e; for example, A-4E, P-3B
