## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, and -400ER series airplanes. This proposed AD was prompted by multiple reports of un- commanded escape slide inflation. This proposed AD would require modifying the regulator valves of the forward entry door, forward service door, aft entry door, and aft service door, and as applicable, modifying the regulator valves of the mid entry door and mid service door. We are proposing this AD to prevent out-of-tolerance trigger mechanism components (sector and sear) in the regulator valves, which can produce insufficient trigger engagement and reduced pull force values, possibly leading to un-commanded deployment of the slide during normal airplane maintenance or operation, and could result in injury to passengers and crew, damage to equipment, and the slide becoming unusable in an emergency evacuation.
