Models named: 767-200, -300, -400ER series. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

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.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

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)). (2) For the airplane having variable number VN 137: Within 48 months after the effective date of this AD. (3) Use the following service information, as applicable, to accomplish the actions required by paragraph (g) of this AD. (i) Boeing Special Attention Service Bulletin 767-25-0428, dated August 23, 2007. (ii) Boeing Special Attention Service Bulletin 767-25-0428, Revision 1, dated May 8, 2008. (iii) Boeing Special Attention Service Bulletin 767-25-0428, Revision 3, dated October 21, 2010.

Unsafe condition

This AD was prompted by reports that entry and service doors did not open fully during deployment of emergency escape slides, and reports of missing snap rings. 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.

Affected ADs

This AD supersedes AD 2009-04-12, Amendment 39-15818 (74 FR 8717, February 26, 2009).
