Section 4. CANCELING/EXTENDING
4-4-1. EXTENDING NOTAM DURATION
When there is a need
to extend an existing NOTAM time duration, cancel the original NOTAM and
reissue the data as a new NOTAM with the new time.
a. To cancel a
NOTAM, use the same serial number assigned to the original NOTAM by the USNS
computer, preceded by the letter “C.” If the serial number of a NOTAM
cancellation is invalid (number not in a master file), no action is taken
within the NOTAM system. A cancellation shall receive the same dissemination
as the NOTAM it cancels. Do not carry the NOTAM text in the cancellation.
canceling NOTAMs shall check the NOTAM data to insure the NOTAMs deletion.
Retransmit cancellations not acted upon.
NOTAMs containing erroneous information and reissue. Transmit a new NOTAM
when data is received amending a current NOTAM, and cancel the previous
PUBLISHED NOTAM DATA
a. When data
appearing in a NOTAM is printed correctly in a publication or on a chart,
cancel the NOTAM, but not the data. The cancellation must be formatted in
the following manner:

!DEF C06/006 CHARTED

means the NOTAM is canceled; e.g., !GHI C07/007

remain current until the data is published in one or more of the following,
