COMPLIANCE INFORMATION RELATED TO THIS REVISION Federal Aviation Administration (FAA) Airworthiness Directive AD 2009-22-13, is related to this service bulletin.

More work is necessary on airplanes VF181-VF184 changed in accordance with the original issue or Revision 1 of this service bulletin. These airplanes must be in Group 1 since they are equipped with equipment numbers V00157, V00158, V00159 and V00160.

REASON FOR REVISION This revision is sent to correct the effectivity, applicability, summary of hours in the Manpower tables, a number of typographical errors, and nomenclature in the figures. The changes are as follows:

1. In paragraph 1.A. Effectivity, moved VF181-VF184 from Group 4 to Group 1 to include equipment numbers V00157, V00158, V00159 and V00160.

2. In Summary, Manpower, corrected the total tasks hours and elapsed time in the summary table.

3. In paragraph 1.G, Manpower, corrected the applicability in the Work Package summary tables title: "Only the Work Packages for these Groups".

4. In Figure 7, Illustration, removed the applicability. Refer to the applicability in the Accomplishment Instructions.

5. In Figure 7, Illustration, removed the sentence "This figure has been deleted." This was a typographical error.

6. In Figure 13, Step Table, Step 1, QTY, revised the QTY to one (1).

7. In Figure 22, Illustration, removed the applicability. Refer to the applicability in the Accomplishment Instructions.

8. In Figure 23, Illustration, removed the applicability. Refer to the applicability in the Accomplishment Instructions.

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

Commercial Airplanes 767 Service Bulletin SummaryNumber: 767-28A0090Original Issue: July 03, 2008 Revision 2: September 02, 2010 ATA System: 2822 2825 2826 2831 SUBJECT: FUEL - Main and Center Tanks - Valve Actuator Inspection and Replacement

CONCURRENT REQUIREMENTS None.

BACKGROUND This service bulletin gives instructions to inspect all the motor operated valve (MOV) actuators and to install new MOV actuators where necessary. 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 767 Maintenance Planning Data (MPD) Document was change.

ACTION (PRR B13421-6) — 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 MA20A1001-1 is the only installed MOV actuator part number that is affected by this service bulletin.

— If you are required to install the MA30A1001, you must do an electrical resistance check at 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. This may require a tank entry to rework the interface between the adapter and the airplane structure.

— If you are required to install the MA30A1001 at the dual forward/aft engine fuel crossfeed valve actuator location, you must inspect for the "SWEENEY ENGR CORP" marking on the adapter. If found, you must install the shim kit.

— Some airplane models have a deflector installed at the left and right engine fuel shutoff MOV actuator location, where an installed wire support assembly can potentially interfere with the new MOV actuator. If you are required to install the MA30A1001 at these locations, you must also install the new wire support assembly on the deflector. The new wire support assembly will prevent part interference.

— Close access to each MOV actuator.

EFFECTIVITY 767 -200 /-300 /-300F /-400ER airplanes. Refer to Paragraph 1.A., Effectivity for the list of effected airplanes.

COMPLIANCE Federal Aviation Administration (FAA) Airworthiness Directive 2009-22-13 is related to this service bulletin.

Boeing recommends that this service bulletin be incorporated within 60 months from the effective date of FAA AD 2009-22-13.

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