Commercial Airplane Group 767 Service Bulletin ALERT Revision Transmittal SheetNumber: 767-78A0089Date: July 19, 2001 Revision 5: June 09, 2009 ATA System: 7831 SUBJECT: EXHAUST (JT9D ENGINE) - Thrust Reverser Sleeve - Improved Thrust Reverser Deactivation Pin Modification This revision includes all pages of the service bulletin.

COMPLIANCE INFORMATION RELATED TO THIS REVISION Group 1:

No more work is necessary on airplanes changed as shown in Revision 2, Revision 3, or Revision 4 of this service bulletin.

Group 2:

More work is necessary on airplanes changed as shown in Revision 2, Revision 3, or Revision 4 of this service bulletin. Airplanes that delivered with the 315T3222-3 bushing need to replace the 315T3222-3 bushing with the 315T3221-1 bushing. If Group 2 operators previously replaced the 315T3222-3 bushing with the 315T3222-10 bushing, the 315T3222-10 bushing must be replaced by the 315T3221-1 bushing due to inadequate edge margin.

Federal Aviation Administration (FAA) Airworthiness Directive 2002-19-11, is related to this service bulletin.

REASON FOR REVISION This revision is sent to add the 315T3221-1 bushing installation for airplanes delivered with the 315T3222-3 bushing. Revision 4 of this service bulletin added the 315T3222-3 bushing configuration. However, Boeing received a report from an operator that the 315T3222-3 bushing could not be replaced by the 315T3222-10 bushing due to inadequate edge margin. Therefore, this revision replaces the 315T3222-3 bushing with a new 315T3221-1 bushing that will provide adequate edge margin.

These sections were changed:

1. In Effectivity - Airplanes, paragraph 1.A.1., airplanes that delivered with the 315T3222-3 bushing configuration were moved to a new Group 2.

2. In Material - Price and Availability, paragraph 2.A., price and ROLT data is added for the new 015T1838-1 and 015T1838-2 kits. Also, notes are added to clarify the correlation of the new kits to the old kits for Group 2 airplanes.

3. In Kits/Parts, paragraph 2.C.1., a table was added for the new 015T1838-1 and 015T1838-2 kits.

4. In Work Instructions, paragraph 3.B., Step 4 was added to Work Package 2 for Group 2 airplanes.

5. In Figure 4, Step 5 was added to inspect for cracks, and Step 11 was changed to wet install the fasteners.

6. Figure 11 was added for Group 2 airplanes.

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.

CONCURRENT REQUIREMENTS None

BACKGROUND The Federal Aviation Administration (FAA) has issued an Airworthiness Directive (AD) which requires incorporation of this service bulletin.

This service bulletin provides modification instructions to improve the thrust reverser deactivation pin's structural integrity. This modification will ensure non-deployment of a deactivated thrust reverser.

Four partial deployments of improperly deactivated thrust reversers have been reported by operators with PW4000 engines. These occurred during landing, with up to 12 inches of the reverser deployed. Investigation of these events found that the, motorized isolation valve was not locked-out, as required by the 767 Dispatch Deviations Guide. This allowed hydraulic pressure to be available to the actuators when the reverser levers were activated on landing. The pin insert, located on each reverser sleeve, did not completely resist the deployment loads and twisted out of place allowing movement of the deactivated thrust reverser. The JT9D thrust reverser design is similar to the PW4000 thrust reverser design.

Further investigation and analysis by Boeing has also found that the current deactivation pin arrangement may not always restrain a reverser against a full powered deployment.

The improved deactivation pin modification consists of: (1) replacing the pin insert with one that has increased load carrying capability, (2) the bushing in the aft cascade ring is replaced with one that allows clearance for the new insert and (3) the deactivation pin is replaced with a longer one which will engage the cascade bushing despite any tolerances in the reverser.

Boeing Service Related Problem (SRP) 767-SRP-78-0042 is related to this service bulletin.

ACTION (PRR B13498-R) For each reverser half, replace the aft cascade bushing, sleeve insert, and the deactivation pin with new components.

EFFECTIVITY All JT9D powered 767 airplanes.

COMPLIANCE Boeing recommends incorporation of this service bulletin within 24 months after November 5, 2002.

Federal Aviation Administration (FAA) Airworthiness Directive 2002-19-11, Amendment 39-12891, is related to this service bulletin.
