2001-26-19 Boeing: Amendment 39-12585. Docket 2001-NM-311-AD. \n\n\tApplicability: Model 767 series airplanes, line numbers 1 through 854 inclusive, certificated in any category. \n\n\tNote 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 request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it. \n\n\tNote 2: Boeing Service Letter 767-SL-25-101, dated August 30, 2001, provides information related to this AD; however, the actions required by this AD are not identical to those in the "Suggested Operator Action" section of that service letter. Where this AD differs from the service letter, this AD prevails. \n\n\tCompliance: Required as indicated, unless accomplished previously. \n\n\tTo 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 and result in injury to passengers or crewmembers, accomplish the following: \n\nOne-Time Inspection and Corrective Actions \n\n\t(a) Within 60 days after the effective date of this AD, do a one-time detailed visual inspection for missing, damaged, or incorrectly installed parts in the separation link assembly on the deployment bar of the emergency escape system on the entry or service door, according to the procedures specified in paragraphs (a)(1), (a)(2), (a)(3), (a)(4), (a)(5), and (a)(6) of this AD. \n\n\t\t(1) Remove the escape slide pack bustle according to Section 25-66-00 of the Boeing 767 Airplane Maintenance Manual (AMM). \n\n\t\t(2) Position the deployment bar of the escape slide to expose the forward and aft separation links, according to Section 25-66-00 of the Boeing 767 AMM and Section 25-66-30 of the Boeing 767 Component Maintenance Manual (CMM), Revision 2, dated November 1, 2000. \n\n\t\t(3) Do a detailed visual inspection to determine whether the snap ring, washer, and internal spring of the separation link assembly are installed correctly on both the forward and aft separation links, and to detect any damage of the snap ring, washer, and spring, according to Items 65 and 70 of Section 25-66-30 of the CMM, Revision 2, dated November 1, 2000. \n\n\t\t(4) If any snap ring, washer, or internal spring is missing or found damaged or installed incorrectly during the inspection required by paragraph (a)(3) of this AD, before further flight, install a new snap ring, washer, and internal spring according to Section 25-66-30 of the CMM, Revision 2, dated November 1, 2000. \n\n\t\t(5) Ensure that the separation links and deployment cables are installed as depicted on placard BAC27TPPS5141 or BAC27TPPS5142, as applicable. Placards are adjacent to each link on the deployment bar. If any separation link or deployment cable is installed incorrectly, before further flight, correct the installation as shown on the applicable placard. \n\n\t\t(6) Reinstall the escape slide pack bustle according to Section 25-66-00 of the Boeing 767 AMM. \n\n\tNote 3: For the purposes of this AD, a detailed visual inspection is defined as: "An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required." \n\nReporting Requirement \n\n\t(b) If there is any missing, damaged, or incorrectly installed part in the separation link assembly on the deployment bar of the emergency escape system on any entry or service door: Submit a report of inspection findings to the FAA Certification Management Office--Boeing, ANM-108B, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; at the applicable time specified in paragraph (b)(1) or (b)(2) of this AD. The report must include: the serial number of the affected airplane, the total number of doors inspected, the number of deployment bars with missing or damaged parts, an identification of what parts are missing or damaged, and the calendar date of the last inspection or test of any emergency escape system with missing or damaged parts. Information collection requirements contained in this AD have been approved by the Office of Management and Budget (OMB) under the provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et seq.) andhave been assigned OMB Control Number 2120-0056. \n\n\t\t(1) For airplanes on which the inspection is accomplished after the effective date of this AD: Submit the report within 10 days after performing the inspection required by paragraph (a) of this AD. \n\n\t\t(2) For airplanes on which the inspection has been accomplished before the effective date of this AD: Submit the report within 10 days after the effective date of this AD. \n\nAlternative Methods of Compliance \n\n\t(c) 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. 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. \n\n\tNote 4: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO. \n\nSpecial Flight Permits \n\n\t(d) 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. \n\nIncorporation by Reference \n\n\t(e) The exposure of the forward and aft separation links; inspection for snap ring, washer, and internal spring; and installation of new snap ring, washer, and internal spring; shall be done in accordance with Section 25-66-30 of the Boeing 767 Component Maintenance Manual, Revision 2, dated November 1, 2000, which contains the following effective pages: \n\n\nPage number \nRevision level shown on page\nDate shown on page \nList of Effective Pages; Page 1\n2\n Nov. 1, 2000.\n\n(Only the "Highlights" page of Section 25-66-30 shows the appropriate revision level; no other page of this document contains the revision level.)
