C. Reason This service bulletin will prevent the partial opening of the entry/service doors during emergency escape slide deployment. If the entry/service doors do not fully open the exit may not be available for emergency evacuation use.
Boeing has received five reports since 1993 of partial entry/service door opening during escape slide deployment testing. Boeing has also received one report of partial entry/service door opening during an actual airplane emergency evacuation.
These events were the result of the separation link assembly on the slide deployment bar not properly rotating to release the deployment cable. It was found that the snap rings attaching the separation links to the deployment bar were missing. Loss of a snap ring will result in movement of the separation link assembly past the stop screws. Movement of the separation link assembly past the stop screws will prevent full rotation of the separation link assembly and normal release of the deployment cable. If the deployment cables do not release from the separation link assemblies on the deployment bar, the un-released deployment cables will prevent full opening of the entry/service door. Service Letter 767-SL-25-101-A was issued to instruct operators to inspect the separation link assemblies for missing or damaged snap links.
This service bulletin installs separation link assemblies secured with a nut and washer instead of a snap ring. The installation of a separation link assembly secured with a nut and washer will prevent movement of the separation link assembly past the stop screws and make sure the service/entry doors open fully in an emergency evacuation.
Boeing Service Related Problem (SRP) 767-SRP-25-0258 is related to this service bulletin.
Revision 1 is sent to incorporate changes found during validation of this service bulletin.
These sections were changed:
1. In Kits/Parts, Section 2.C.1., added existing part numbers to parts table.
2. In Parts Modified and Reidentified, Section 2.C.3., Groups 1-2, deleted 767-25-0428 as the new part number and deleted note (c).
3. In Parts Necessary to Change Spares, Section 2.D., added Spares Kit 015T1811-3
4. Figures 5 and 6, Steps 1 and 9, added reference to Figure 501 in CMM 25-66-30.
5. Figures 5 and 6, Steps 6 and 14, deleted reference to SOPM 20-50-01 and added torque values of 15 - 16 in-lbs.
Revision 2 is sent to update the effectivity and add FAA Airworthiness Directive 2009-04-12. The part number of a cap screw has been changed in figures 3, 4, 5 and 6, and an optional part number added.
Optional part numbers have also been added for the deployment bar assemblies in section 2.C.3, Parts Modified and Reidentified, and figures 7, 8, 9 and 10.
The data given in Information Notice 767-25-0428 IN 02 is included in this revision. This Information Notice was sent to provide the pricing information for the 015T1811-3 spares kit in section 2.A., Material

F. Approval This service bulletin was examined by the Federal Aviation Administration (FAA). The changes specified in this service bulletin comply with the applicable regulations and are FAA approved, as well as European Aviation Safety Agency (EASA)/Joint Aviation Authorities (JAA) approved for all EASA/JAA approved airplanes listed in the service bulletin effectivity. This service bulletin and its approval were based on the airplane in its original Boeing delivery configuration or as modified by other approved Boeing changes.
If an airplane has a non-Boeing modification or repair that affects a component or system also affected by this service bulletin, the operator is responsible for obtaining appropriate regulatory agency approval before incorporating this service bulletin.
This service bulletin has been approved by the FAA. In addition, the Manager of the FAA Seattle Aircraft Certification Office approves the action (i.e. inspection or modification) defined in this service bulletin as an alternative method of compliance to the requirements of paragraph (f) of AD 2009-04-12. All provisions of AD 2009-04-12 that are not specifically referenced in the above statement remain fully applicable and must be complied with.
G. Manpower The table below shows an estimate of the task hours necessary to do this change for each airplane.
This estimate is for direct labor only, done by an experienced crew. Adjust the estimate with operator task hour data if necessary. The estimate does not include lost time. These are some examples of lost time:
Time to adjust to the workplace Time to schedule the work Time to inspect the work Time to cure the materials Time to make the parts Time to find the tools.
