Summary

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, and -400ER series airplanes. This AD was prompted by multiple reports of uncommanded escape slide inflation. This AD requires modifying the escape slide regulator valves of the forward-entry door, forward-service door, aft-entry door, and aft-service door, and as applicable, modifying the escape slide regulator valves of the mid-entry door and mid-service door. 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.
