BACKGROUND
This service bulletin replaces door mounted escape slides and slide-rafts with slide-rafts that can reach the
ground if the airplane is in an extreme tip-back position. At entry and service doors with escape slides installed,
this service bulletin also replaces or modifies the counterbalance assemblies so that the doors will operate
correctly with the heavier escape slide-rafts installed.
While calculating the new adverse sill heights for the 767-400 evacuation systems, it was determined that the
analyses for the highest sill height condition for the exits on the 767-200 and -300 were no longer valid. These
earlier analyses showed that the engine nacelle strut would break away in the event of a main landing gear
failure on that side of the airplane. Recent tests on the engine nacelle strut shows a higher strength than originally
calculated resulting in the highest sill height at the forward and mid-cabin doors occurring with the airplane
resting on one main gear, the opposite engine and the aft fuselage. In this condition, the existing escape slides
and slide-rafts at the forward and mid-cabin entry and service doors will be too short to reach the ground. The
escape slides should be long enough to reach the ground in the most extreme conditions.
The longer escape slide-rafts will allow passengers to safely evacuate the airplane if it is in an extreme tip-back
position.
Boeing Service Related Problems (SRP) 767-SRP-25-0137 and 767-SRP-25-0248 are related to this service
bulletin.
ACTION (PRR B12901-72S)
On Group 1 airplanes, replace the escape slide-rafts at the forward entry and service doors and change the
latches.
On Group 2 airplanes, replace the escape slide-rafts at the forward and mid-cabin entry and service doors and
change the latches.
On Group 3 airplanes, replace the escape slides at the forward entry and service doors and change the latches.
Replace the counterbalance assemblies.
On Group 4 airplanes, replace the escape slides at the forward entry and service doors and change the latches.
Replace or modify the counterbalance assemblies.

The longer escape slide-rafts will allow passengers to safely evacuate the airplane if it is in an extreme
tip-back position.
Revision 1 was sent to change the escape slides and escape slide/rafts installed from part numbers
S416T214-1, -2, -3 and -4 to S416T214-11, -12, -13 and -14. And, add instructions to replace the cable
and test the valve of the inflation trigger system of the escape slide/raft as given in Boeing Service
Bulletin 767-25-0395. Also, add instructions for Group 1 and Group 2 airplanes to adjust the door
counter balance system.
Changes are made to the following sections:
1. Material Information:
a. Changed escape slides and escape slide/rafts from S416T214-1, -2, -3, and -4 to S416T214-11,
-12, -13 and -14 in Operator Furnished Parts.
b. The Existing Parts Accountability is moved to APPENDIX A.
2. Accomplishment Instructions:
a. Added information that airplanes changed as shown in the original issue of this service bulletin
must replace the cable and test the valve of the inflation trigger system of the escape slide/rafts
as given in Boeing Service Bulletin 767-25-0395.
b. Added instructions for Group 1 and Group 2 airplanes to adjust door counter balance systems
as shown in 767 AMM 52-11-16.
3. Figure 1.
a. Escape slide - rafts S416T214-1 and S416T214-2 changed to S416T214-11 and S416T214-12
in Step 16.
4. Figure 4.
a. Escape slide - rafts S416T214-3 and S416T214-4 changed to S416T214-13 and S416T214-14

Boeing Service Related Problem (SRP) 767-SRP-25-0137 and 767-SRP-25-0137 is related to this
service bulletin.
Revision 2 is sent to correct the slide/raft specification numbers shown in the Materials paragraph. The
S416T214-12 slide/raft does have an ELT and the S416T214-11 does have an ELT.
These sections were changed:
1. Section 2. Material Information., The slide-raft assembly part numbers have been corrected. In
addition a note has also been corrected.
Revision 3 is sent to correct the slide-raft assembly part numbers in the materials section.

1. Section 2. Material Information., The slide-raft assembly part numbers have been corrected.
2. Figures 1 and 4., The slide-raft assembly part numbers have been corrected in note (a) in the step
tables.
D. Description
On Group 1 airplanes, replace the escape slide-rafts at the forward entry and service doors and change
the latches.
On Group 2 airplanes, replace the escape slide-rafts at the forward and mid-cabin entry and service
doors and change the latches.
On Group 3 airplanes, replace the escape slides at the forward entry and service doors and change
the latches. Replace the counterbalance assemblies.
On Group 4 airplanes, replace the escape slides at the forward entry and service doors and change
the latches. Replace or modify the counterbalance assemblies.
On Group 5 airplanes, replace the escape slides at the forward and mid-cabin entry and service doors
and change the latches. Replace or modify the counterbalance assemblies at the forward entry and
service doors.
The airplane effectivity is divided in five groups because of different door and counterbalance
configurations.
