COMPLIANCE INFORMATION RELATED TO THIS REVISIONo

No more work is necessary on airplanes changed as shown in the initial release of this service bulletin.

Federal Aviation Administration (FAA) Airworthiness Directive 99-17-20, Amendment 39-11266, is related to

this service bulletin.

Airplane ND895 was added to the service bulletin effectivity. Airplanes NU701 and NU721-NU723 were

removed from this service bulletin. The effectivity for a circuit breaker was corrected.

REASON FOR REVISION

This revision is sent to add a reference to the FAA Airworthiness Directive 99-17-20, Amendment 39-11266.

This revision removes 757-300 airplanes from the effectivity and adds airplane ND895. In addition, the

effectivity for a circuit breaker was corrected.

For 757-300 airplanes, this service bulletin is replaced by Service Bulletin 757-25-0219.

As part of a service bulletin validation program, this change was completed on airplane NT795 by Service

Bulletin 757-25-0200 (Rapid Revision RR92025-22V) before the initial release of this service bulletin.

Paragraph 1.A., Effectivity, shows changes of airplane operators. Each operator should examine the

Effectivity paragraph for changes.

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

BACKGROUND

The Federal Aviation Administration (FAA) has

issued an Airworthiness Directive (AD) which

requires incorporation of Service Bulletin

757-25-0200, Revision 0. This service bulletin is

equivalent to Service Bulletin 757-25-0200, Revision

0. Service Bulletin 757-25-0200, Revision 0, was

separated into two service bulletins. Service

Bulletin 757-25-0200, Revision 1, applies to 757-200

airplanes. Service Bulletin 757-25-0219 applies to

757-300 airplanes.

This change will prevent off-wing slide loss while in

flight due to the slide compartment door opening.

Five operators have reported loss of an off-wing

slide while in flight. In each of these incidents, the

slide compartment door opened, the slide carrier

rotated out and the slide departed from the aircraft.

This may result in tears and punctures in the wing

flaps and airplane skin.

This service bulletin gives instructions to add a

bumper to the bottom of the off-wing escape slide

carrier. The bumper forces the carrier to stay in the

fully stowed position when the off-wing slide

compartment door is faired. In the fully stowed

position the locking pin for the slide carrier will line

up with the hole in the carrier lock fitting. This

allows the carrier to be locked without the

opportunity for the locking pin to jam.

As part of a service bulletin validation program, this

change was completed on airplane NT795 by

Service Bulletin 757-25-0200 (Rapid Revision

RR92025-22V) before the initial release of this

service bulletin.

Boeing Service Related Problem (SRP)

757-SRP-25-0140 is related to this service bulletin.

ACTION (PRR 54530-209)

On the left and right off-wing escape systems.

Install a bumper assembly on the off-wing slide

carrier. Install a witness mark placard on the lip of

the maintenance access door opening. Install a new

instruction placard on the back of the maintenance

access door.

EFFECTIVITY (757-200 airplanes with over-wing

exits)

C. Reason

The Federal Aviation Administration (FAA) has issued an Airworthiness Directive (AD) which requires

incorporation of Service Bulletin 757-25-0200, Revision 0. This service bulletin is equivalent to

Service Bulletin 757-25-0200, Revision 0. Service Bulletin 757-25-0200, Revision 0, was separated

This may result in tears and punctures in the wing flaps and airplane skin.

This service bulletin gives instructions to add a bumper to the bottom of the off-wing escape slide

compartment door is faired. In the fully stowed position the locking pin for the slide carrier will line up

the locking pin to jam.

As part of a service bulletin validation program, this change was completed on airplane NT795 by

Service Bulletin 757-25-0200 (Rapid Revision RR92025-22V) before the initial release of this service

bulletin.

Boeing Service Related Problem (SRP) 757-SRP-25-0140 is related to this service bulletin.

Revision 1 - Airplane ND895 was added to the service bulletin effectivity. This bulletin applies to

service bulletin. For 757-300 airplanes, this service bulletin is replaced by Service Bulletin

757-25-0219. In the Accomplishment Instructions, the effectivity for a circuit breaker was corrected.

D. Description

On the left and right off-wing escape systems: A bumper assembly is installed on the off-wing slide

carrier. A witness mark placard is installed on the lip of the maintenance access door opening. A

new instruction placard is installed on the back of the maintenance access door.

This procedure must be completed with the 140N0811 Access Door removed from the 140N0810

Container Assembly. A container assembly is located in the upper aft outboard corner of the main

gear wheel well on both the left and right sides.

(a) Person 1 - Locate person 1 on trailing edge by the off-wing escape slide system to get access to

the slide compartment door and the escape slide system maintenance access door.

(b) Person 2 - Locate person 2 in the wheel well at the 140N0810 Container Assembly.

II. Person 1 - Can slide compartment door be closed and faired with yellow crank handle in unlocked (full

up) position?

(a) If yes - Hold slide compartment door in faired position for Steps III. and IV.

(b) If no - Remove one NAS1149E0363 washer from each screw on bumper assembly. Return to

Step II.

III. Person 2 - Push carrier outboard until contact is made with slide compartment door and bumper. Hold

this position while performing Step IV.

IV. Person 1 - Attempt to lock system by releasing trigger and moving yellow crank handle to locked

position. Does yellow crank handle move normally to the locked position?

(a) If no and yellow crank handle jams before it reaches the locked position - Add one NAS1149E0363

washer to each screw on bumper assembly. Return to Step III.

(b) If no and moving the yellow crank handle to the locked position requires higher than normal forces

on the crank handle and the bottom of the slide compartment door deflects outward, 0.01 inches to

0.18 inches further than the previously faired condition - Remove one NAS1149E0363 washer from

each screw on bumper assembly. Return to Step IV.

(c) If yes - Step IV. Complete. Rigging of bumper complete.
