[Bryan Herbert]

KZLA LOS ANGELES (ARTCC)PALMDALE, CA.

 A0371/05 -  THE JAPAN CIVIL AVIATION BOARD (JCAB) WILL BEGIN TESTING
ON A NEW MULTI-FUNCTIONAL TRANSPORT SATELLITE (MTSAT). THIS ADDITION
OF A FIFTH SATELLITE IN THE INMARSAT SYSTEM MAY CAUSE CERTAIN MODELS
OF THE ROCKWELL COLLINS SATCOM TO FAIL. SATCOM MODELS SUSCEPTIBLE TO
THIS PROBLEM ARE LISTED IN ROCKWELL COLLINS SERVICE INFORMATION
LETTERS (SIL) 05-1 FOR BOTH THE SRT-2000 SERIES SATELLITE RECEIVER-
TRANSMITTER UNIT AND THE SDU-906 SERIES SATELLITE DATA UNIT (DATED
MARCH 31, AND APRIL 1, 2005, RESPECTIVELY). THIS FAILURE WILL OCCUR
REGARDLESS OF THE REGION IN WHICH THE AIRCRAFT IS OPERATING. THE
POSSIBLE FAILURE OF THESE ROCKWELL COLLINS SATCOMS, WHILE THIS FIFTH
SATELLITE IS FUNCTIONAL, WILL REMAIN UNTIL THE OPERATOR ACCOMPLISHES
THE NECESSARY CORRECTIVE PROCEDURES LISTED IN THE ROCKWELL COLLINS
SERVICE INFORMATION LETTERS NOTED ABOVE. CONSEQUENTLY AFTER
0508250000, AIRCRAFT EQUIPPED WITH ROCKWELL COLLINS SATCOMS IDENTIFIED
IN THESE SIL(S), WHICH HAVE NOT BEEN UPDATED, WILL BE UNABLE TO
CONDUCT VOICE OR DATA SATELLITE COMMUNICATIONS, TO INCLUDE CONTROLLER
PILOT DATA LINK COMMUNICATIONS (CPDLC) AND/OR AUTOMATIC DEPENDENT
SURVEILLANCE (ADS). THIS SATCOM FAILURE MAY REQUIRE THE USE OF HF DATA
LINK OR VOICE COMMUNICATIONS FOR AIR TRAFFIC CONTROL, COMPANY, AND/OR
OTHER COMMUNICATIONS THROUGHOUT AIRSPACE WORLDWIDE. MORE INFORMATION
