2. Spares Affected Group 1, Configuration 1:
Examine your spares supply for 512Z2001-1, -2, or -3 Inner Cylinder Assemblies. If any of these Inner Cylinder Assemblies are found, remove the Aluminum-Nickel-Bronze Inner Cylinder Bushings 512Z3002-1 and replace with Copper-Nickel-Tin Inner Cylinder Bushings 512Z3002-2. Refer to CMM 32-11-74 as an accepted procedure.
Identify on the part that the change given in this bulletin was done. Use the rubber stamp (Code RO) or ink jet (Code J) method. Refer to SOPM 20-50-10 as an accepted procedure.
Group 1, Configuration 2 and Group 2: None B. CONCURRENT REQUIREMENTS None.
C. COMPLIANCE The Federal Aviation Administration (FAA) will possibly release an Airworthiness Directive related to Requirements Bulletin B787-81205-SB320045-00 RB. The Airworthiness Directive will make the compliance tasks and times given in Requirements Bulletin B787-81205-SB320045-00 RB mandatory.
Accomplish the required actions, based on applicable conditions in Table 5, Table 6, Table 7, Table 8, and Table 9 in accordance with Accomplishment Instructions.
When more than one OPTION is given for a CONDITION, do only one of the OPTION numbers. When more than one ACTION is given for a CONDITION number or an OPTION number, do all of the ACTION numbers for that CONDITION number or OPTION number.
