AD 95-08-11 Airworthiness Directives; Boeing Model 767 Series Airplanes Equipped With Off-Wing Escape Slides

Models named: 767 series. Read the applicability below — it usually turns on serial or part numbers too.

Model 767 series airplanes equipped with off-wing escape slides, certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must use the authority provided in paragraph (e) to request approval from the FAA. This approval may address either no action, if the current configuration eliminates the unsafe condition; or different actions necessary to address the unsafe condition described in this AD. Such a request should include an assessment of the effect of the changed configuration on the unsafe condition addressed by this AD. In no case does the presence of any modification, alteration, or repair remove any airplane from the applicability of this AD.

Required as indicated, unless accomplished previously. To prevent failure of the escape slide to deploy, which could delay and possibly jeopardize successful emergency evacuation of an airplane, accomplish the following: (a) Within 18 months after November 25, 1992 (the effective date of AD 92-16-17, amendment 39-8327), inspect the off-wing escape slide door opening/snubbing actuators in accordance with OEA Service Bulletin 3092100-25-002, dated July 26, 1991. Repeat this inspection thereafter at intervals not to exceed 20 months until the replacement required by paragraph (c) of this AD is accomplished. For operators that have previously accomplished this inspection in accordance with AD 92-16-17: This paragraph requires that the next scheduled inspection be performed within 20 months after the last inspection performed in [[Page 20016]] accordance with paragraph (b)(1) of AD 92-16-17. (b) Within 18 months after November 25, 1992 (the effective date of AD 92-16-17, amendment 39-8327), inspect and modify the escape slide compartment door latching mechanism in accordance with Boeing Alert Service Bulletin 767-25A0174, dated August 15, 1991. Accomplishment of the actions required by this paragraph prior to the effective date of this AD terminates the actions required by paragraph (b)(2) of AD 92-16-17. (c) Within 2 years after the effective date of this AD, replace the currently installed door opening actuator of the emergency off- wing escape system with a new, improved actuator, in accordance with Boeing Service Bulletin 767-25-0216, dated February 3, 1994. Accomplishment of this replacement terminates the repetitive inspection requirements of paragraph (a) of this AD. (d) As of 2 years after the effective date of this AD, only door opening actuators of the emergency off-wing escape system having OEA part number 5262100 (Boeing part number S416T208-12) shall be installed on any airplane. (e) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Seattle ACO. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO. (f) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. (g) The replacement shall be done in accordance with Boeing Service Bulletin 767-25-0216, dated February 3, 1994. This incorporation by reference is approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. The inspections and modification shall be done in accordance with OEA Service Bulletin 3092100-25-002, dated July 26, 1991, and Boeing Alert Service Bulletin 767-25A0174, dated August 15, 1991; as applicable. The incorporation by reference of these documents was approved previously by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51 as of November 25, 1992 (57 FR 47987, October 21, 1992).
