COMPLIANCE INFORMATION RELATED TO THIS REVISION Federal Aviation Administration (FAA) Notice of Proposed Rule Making NPRM 2008-NM-056-AD, is related to this service bulletin.

No more work is necessary on the airplane(s) changed in accordance with the original issue or Revision 1 of this service bulletin.

REASON FOR REVISION This revision is sent to inform operators of the following corrections to apply cap seal to the fasteners of the Motor Operated Valve (MOV) actuator bonding jumper fasteners:

– In paragraph 2.C., Parts Necessary For Each Airplane, the QTY for BMS 5-95 was increased to reflect the approximate total amount to consume when applying cap seal to the bonding jumper fasteners.

– In paragraph 2.C., Parts Necessary For Each Airplane, footnote (e) was added to clarify optional part numbers for BMS 5-95 when applying cap seal on the bonding jumper fasteners.

– In Figure 7, Figure 21, and Figure 22, for the install of the MOV actuator, the step table was revised to add a step to apply cap seal on the bonding jumper fasteners after measuring the electrical bond resistance.

– In Figure 7, Figure 21, and Figure 22, footnote (f) was added to clarify optional part numbers for BMS 5-95 when applying cap seal on the bonding jumper fasteners.

The information given in Information Notice 777-28A0034 IN 3 is included in this revision.

Vertical lines are put on the left edge of each page, except in Paragraph 1.A., Effectivity, to show the location of important changes.

Pages with no vertical lines have no important changes.

Commercial Airplanes 777 Service Bulletin SummaryNumber: 777-28A0034Original Issue: August 02, 2007 Revision 2: September 20, 2010 ATA System: 2822 2825 2826 2831 SUBJECT: FUEL - Main and Center Tank Valve Actuators - Inspection and Replacement

CONCURRENT REQUIREMENTS None

BACKGROUND This service bulletin gives instruction to inspect all the motor operated valve (MOV) actuators and to install new MOV actuators where necessary. The MOV actuators are installed at each fuel system. The new MOV actuator will prevent electrical current flow through the actuator into the fuel tank. If this service bulletin is not done it is possible that a flow of electricity into the fuel tank will supply an ignition source for the fuel fumes in the tank.

The Boeing system safety assessment necessary for Special Federal Aviation Regulation (SFAR) 88, showed that under specific conditions it was possible for electrical current to flow through certain MOV actuators into the fuel tank. A new MOV actuator is available to replace the existing MOV actuator with this condition. The new MOV actuator includes an internal electrical isolator to give the MOV actuator protection against electrical energy from lightning, 115 VAC hot shorts, and 28 VDC internal shorts. The new MOV actuator will prevent the flow of an electrical current into the fuel tank and increase the reliability of the fuel system.

This service bulletin replaces the MOV actuator part number MA20A1001-1 with the new MOV actuator part number MA30A1001. The MOV actuator part number MA20A1001-1 is the only installed MOV actuator part number that is affected by this service bulletin.

This service bulletin gives instruction on how to measure the electrical resistance of bonds at the installed MOV actuator locations, how to prepare a Faying surface for the install of the new MOV actuator, how to prepare affected airplane parts, and how to install the new MOV actuator.

This service bulletin is the result of a safety assessment conducted by Boeing under SFAR 88, "Fuel Tank System Fault Tolerance Evaluation Requirements".

Section 9 of the Maintenance Planning Data (MPD) document was changed.

ACTION (PRR 61777-187, PRR 61998-3) The following actions are necessary:

Original Issue: August 02, 2007 777-28A0034Revision 2: September 20, 2010 7 of 96

Page 8Open in PDF

— Gain access to each MOV actuator.

— Inspect each MOV actuator part number. If the MOV actuator part number is MA20A1001-1, remove, discard, and replace with the MOV actuator part number MA30A1001. The MOV actuator part number MA20A1001-1 is the only installed MOV actuator part number that is affected by this service bulletin.

— If you are required to install the MOV actuator part number MA30A1001, you must do an electrical resistance check of each location. If the measured resistance is not acceptable, you must rework the Faying bond and the airplane parts. This may require rework of the index plate and the adapter plate. This may require a tank entry to rework the interface between the adapter plate and the airplane structure.

— Remove, rework, and reinstall the bracket at the APU Isolation MOV actuator location to prevent part interference with the new MOV actuator part number MA30A1001.

— Close access to each MOV actuator.

EFFECTIVITY 777 -200 /-200LR /-300 /-300ER airplanes. Refer to Paragraph 1.A., Effectivity for the list of affected airplanes.

COMPLIANCE Federal Aviation Administration (FAA) Notice of Proposed Rule Making 2008-NM-056-AD, is related to this service bulletin.

Boeing recommends that operators accomplish this service bulletin be incorporated within 60 months after the original issue date on this service bulletin.

INDUSTRY SUPPORT INFORMATION Boeing warranty remedies are not available for the configuration changes given in this service bulletin.
