Airworthiness Directive · Amendment 39-15795 · Boeing Model 777 Airplanes
Boeing Model 777 Airplanes
This AD applies to Boeing Model 777-200, -200LR, -300, and -300ER series airplanes, certificated in any category; as identified in Boeing Service Bulletins 777-31A0119 and 777-31A0120, both Revision 2, both dated June 12, 2008.
We are adopting a new airworthiness directive (AD) for certain Boeing Model 777 airplanes. This AD requires installing software upgrades to the airplane information management system (AIMS) located in the flight compartment. This AD results from an investigation that revealed that detrimental effects could occur on certain AIMS software during flight. We are issuing this AD to prevent an unannunciated loss of cabin pressure. If an undetected loss of pressure event were to cause an unsafe pressure in the cabin, the flight crew could become incapacitated.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Do the actions specified in paragraphs (f)(1) and (f)(2) of this AD at the time specified, as applicable.
(1) Within 15 months after the effective date of this AD: Install the AIMS Blockpoint 2006 (BP06) operational software by doing all the actions in accordance with the Accomplishment Instructions of Boeing Service Bulletin 777-31A0119 or 777-31A0120, both Revision 2, both dated June 12, 2008; as applicable.
(2) Prior to or concurrently with accomplishing the software installation, install the AIMS Blockpoint 2005A (BP05A) software in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-31-0098, Revision 1, dated May 3, 2007; or Boeing Special Attention Service Bulletin 777-31-0097, Revision 3, dated February 22, 2007; as applicable.
Actions accomplished before the effective date of this AD in accordance with Boeing Service Bulletin 777-31-0119, dated October 16, 2006, or Boeing Alert Service Bulletin 777-31A0119, Revision 1, dated March 27, 2007; and Boeing Service Bulletin 777-31-0120, dated October 16, 2006, or Boeing Alert Service Bulletin 777-31A0120, Revision 1, dated March 23, 2007; are considered acceptable for compliance with the corresponding actions specified in this AD.
