Airworthiness Directive · Amendment 39-14416 · Boeing Model 767-200 and -300 Series Airplanes
Boeing Model 767-200 and -300 Series Airplanes
This AD applies to Boeing Model 767-200 and -300 series airplanes; certificated in any category; equipped with off-wing emergency escape slides; as identified in Boeing Special Attention Service Bulletin 767-25-0358, dated September 18, 2003; and Boeing Special Attention Service Bulletin 767-25-0317, dated June 27, 2002.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200 and -300 series airplanes. This AD requires measuring the turnbuckle gap of the inflation cylinder of the off-wing emergency escape slide; corrective action if necessary; and installing a safety device on the inflation cylinder of the off-wing emergency escape slide. This AD results from a report indicating that the inflation trigger cable may inadvertently disconnect from the inflation turnbuckle of the inflation cylinder of the off-wing emergency escape slide, due to incorrect spacing of the cable insertion gap; and additional reports indicating that the pull force increase mechanism on the off-wing charged cylinder assemblies of the escape slide may be inadvertently disengaged. We are issuing this AD to prevent failed deployment of the emergency escape slide during an emergency, which could impede an evacuation and result in injury to passengers or airplane crewmembers, or inadvertent inflation and loss of an emergency escape slide during flight, which could result in possible structural damage to the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 36 months after the effective date of this AD: Accomplish the actions specified in paragraphs (f)(1) and (f)(2) of this AD.
(1) Measure the turnbuckle gap of the inflation cylinder of the off-wing emergency escape slides to ensure it meets the maximum allowable spacing limit and do applicable corrective actions by doing all the actions specified in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0358, dated September 18, 2003. Accomplish any corrective action before further flight in accordance with the service bulletin.
(2) Install a safety device on the PFIM of the inflation cylinder of the off-wing emergency escape slides, and part-mark the inflation cylinder as applicable, by doing all the actions specified in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0317, dated June 27, 2002.
Note 1: Goodrich Service Bulletins 130104-25-342, dated July 23, 2003; and 130104-25-328, Revision 1, dated July 23, 2003; may be used as additional sources of service information for accomplishing the actions.
As of the effective date of this AD, no person may install an inflation cylinder of the off-wing emergency escape slides on any airplane, unless it has been modified according to paragraph (f) of this AD.
