REFERENCES: /A/ SB 777-55A0018 /B/ MOM-MOM-11-0682-01B DESCRIPTION: As described in ref /A/ SB IN01 and ref /B/ MOM(Multi-Operator Message), currently Boeing does not recommend accomplishment of ref /A/ SB, dated 27 Jul 2011 at this time due to the problems of required parts and tools. Therefore, ANA has not started ref /A/ SB and is waiting for ref /A/ SB rev.1 being released (It would be released in the first quarter of 2012 as noted in ref /B/ MOM). Also, ANA has not ordered any parts and tools, since problems are on them. Boeing informed us that new tool design will be completed in Apr 2012, but available date is unknown, and parts will be available in Oct 2012. Therefore, we would like to request that AD is issued after all the tools and parts are available based on ref /A/ SB rev.1. Best Regrds, Jun Sugita All Nippon Airways
