Models named: 767-200, -300, -400ER series. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to The Boeing Company Model 767-200, -300, and -400ER series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 767-25-0548, Revision 1, dated April 23, 2015.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 42 months after the effective date of this AD, modify the escape slide regulator valves of the forward-entry door, forward-service door, aft-entry door, and aft-service door, and as applicable, modify the escape slide regulator valves of the mid-entry door and mid-service door, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0548, Revision 1, dated April 23, 2015.

Unsafe condition

This AD was prompted by multiple reports of uncommanded escape slide inflation. We are issuing this AD to prevent out-of-tolerance trigger mechanism components (sector and sear) in the escape slide regulator valves, which can produce insufficient trigger engagement and reduced pull force values, possibly leading to uncommanded deployment of the slide during normal airplane maintenance or operation. This condition could result in injury to passengers and crew, damage to equipment, and the slide becoming unusable in an emergency evacuation.

Affected ADs

None.
