BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY.

CONCURRENT REQUIREMENTS

Refer to Paragraph 1.B., Concurrent Requirements.

BACKGROUND

Accomplishment of this service bulletin will ensure that the escape slide packs mounted on the Forward, Mid

and Aft entry and service doors do not experience an un-commanded deployment of the escape slide. If this

service bulletin is not accomplished, un-commanded deployment of the slide during normal airplane maintenance

or operation could result in injury to passengers and crew, damage to equipment, and the slide could not be

used in an emergency evacuation.

Two incidents of uncommanded escape slide inflation have been reported. In both cases, out of tolerance trigger

mechanism components (sector and sear) were found in the regulator valves which produced insufficient trigger

engagement and reduced pull force values.

Accomplishment of this service bulletin will modify the regulator valve by replacing the existing trigger mechanism

sector and sear.

Two incidents of uncommanded escape slide inflation have been reported. In both cases, out of tolerance

trigger mechanism components (sector and sear) were found in the regulator valves which produced

insufficient trigger engagement and reduced pull force values.

Accomplishment of this service bulletin will modify the regulator valve by replacing the existing trigger

mechanism sector and sear.
