AD NUMBER: 2009-20-02

MANUFACTURER: Boeing Model 767-200 and -300 Series Airplanes
SUBJECT: Airworthiness Directive 2009-20-02

SUMMARY:This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-200 and -300 series airplanes, that requires replacing certain door-mounted escape slides and slide- raft assemblies with new slide-raft assemblies. This AD also requires the following actions, as applicable: replacing certain escape system latches with new latches; modifying or replacing certain counterbalance assemblies with new counterbalance assemblies; and adjusting the door counterbalance system. The actions specified by this AD are intended to prevent the escape slides and slide-rafts of the forward and mid-cabin entry and service doors from being too steep for evacuation in the event that the airplane rotates onto the aft fuselage into the extreme tip-back condition. In the extreme tip-back condition, the forward and mid-cabin exits could result in steeper sliding angles, which could cause injury to passengers and crewmembers during an emergency evacuation.
