Airworthiness Directive · Amendment 39-17074 · Equipment/furnishings
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 767-200, -300, and -400ER series airplanes; operating in a passenger or passenger/cargo configuration; certificated in any category; as identified in Boeing Special Attention Service Bulletin 767-25-0428, Revision 3, dated October 21, 2010. The requirements of this AD become applicable at the time an airplane operating in an all-cargo configuration is converted to a passenger or passenger/cargo configuration.
We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, and -400ER series airplanes. That AD currently requires replacing the separation link assembly on the applicable entry and service doors with an improved separation link assembly, and doing related investigative and corrective actions if necessary. This new AD adds an airplane to the applicability and removes certain other airplanes. This AD was prompted by a report that an additional airplane is subject to the unsafe condition. We are issuing this AD to prevent failure of an entry or service door to open fully in the event of an emergency evacuation, which could impede exit from the airplane. This condition could result in injury to passengers or crewmembers.
This paragraph restates the requirements of paragraph (f) of AD 2009-04-12, Amendment 39-15818 (74 FR 8717, February 26, 2009). At the applicable time specified in paragraphs (g)(1) and (g)(2) of this AD, replace the separation link assembly on the deployment bar of the emergency escape system on all the applicable entry and service doors with an improved separation link assembly, and do all the applicable related investigative and corrective actions before further flight, by accomplishing all of the applicable actions specified in the Accomplishment Instructions of any service bulletin identified in paragraphs (g)(3)(i) through (g)(3)(iii) of this AD. After April 2, 2009 (the effective date of AD 2009-04-12), only the service bulletins specified in paragraphs (g)(3)(ii) and (g)(3)(iii) of this AD may be used to accomplish the actions required by this paragraph. After the effective date of this AD, only the service bulletin identified in paragraph (g)(3)(iii) of this AD may be used to accomplish the actions required by this paragraph.
(1) For airplanes other than those having variable number VN 137: Within 48 months after April 2, 2009 (the effective date of AD 2009-04-12, Amendment 39-15818 (74 FR 8717, February 26, 2009)).
