Airworthiness Directive · Amendment 39-16025 · Boeing Model 767-200 and -300 Series Airplanes
Boeing Model 767-200 and -300 Series Airplanes
Model 767-200 and -300 series airplanes, line numbers 1 through 793 inclusive; certificated in any category; equipped with door-mounted escape slide systems; as identified in Boeing Service Bulletin 767-25A0266, Revision 3, dated July 3, 2008.
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. This action is intended to address the identified unsafe condition.
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, accomplish the following:
(a) Within 96 months after the effective date of this AD, replace the applicable slide-rafts at the applicable door or doors, and do all other applicable actions including, but not limited to, changing the latches, and replacing or modifying the counterbalance assemblies, by accomplishing all applicable actions specified in the Accomplishment Instructions in Boeing Service Bulletin 767-25A0266, Revision 3, dated July 3, 2008.
(b) Actions done before the effective date of this AD in accordance with the service bulletins listed in Table 1 of this AD are acceptable for compliance with the corresponding requirements of this AD.
