Applicability*9
Model DC-8-61, -62, -62F, -63, and -63F airplanes equipped with an engine modified by Burbank Aeronautical Corporation II (BAC II) in accordance with Supplemental Type Certificate (STC) SA4892NM or SA5455NM, 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 (d) 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.
Compliance
Required as indicated, unless accomplished previously. To prevent failure of the cone bolt on the right side of the forward mount of the engine, which may lead to separation of the engine during a critical phase of flight, accomplish the following: (a) Within 90 days after the effective date of this AD, perform an inspection to determine the part number (P/N) of the cone bolt on the right side of the forward mount of each of the four engines. (1) If the cone bolt has Barry Controls P/N 96013-1, no further action is required by this AD. (2) If the cone bolt does not have Barry Controls P/N 96013-1, prior to further flight, remove it and install a cone bolt having Barry Controls P/N 96013-1, in accordance with either STC SA4892NM or SA5455NM. Note 2: Intervals for repetitive inspections and replacements of life-limited cone bolts having Barry Controls P/N 96013- are specified in STC's SA4892NM and SA5455NM. (b) Within 10 days after replacing a cone bolt in accordance with the requirements of paragraph (a)(2) of this AD, submit a report that includes the information contained in paragraphs (b)(1), (b)(2), (b)(3), and (b)(4) of this AD, to the Manager, Los Angeles Aircraft Certification Office (ACO), 3960 Paramount Boulevard, Lakewood, California 90712; telephone (310) 627-5323; fax (310) 627- 5210. Information collection requirements contained in this regulation 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.) and have been assigned OMB Control Number 2120-0056. (1) Series and fuselage serial number of Model DC-8 series airplane. (2) Total time and number of cycles on the engine since installation of the engine modified by BAC II in accordance with STC SA4892NM or SA5455NM. (3) Number of bolts identified having BAC II P/N DC-8-21005-7. (4) Number of bolts destroyed having BAC P/N DC-8-21005-7. (c) As of the effective date of this AD, no person shall install, on any airplane, a cone bolt having BAC II P/N DC-8-21005-7 on right side of the forward mount of the engine. (d) 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, Los Angeles 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, Los Angeles ACO. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Los Angeles ACO. (e) Special flight permits may be issued in accordance with Secs. 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. (f) This amendment becomes effective on May 16, 1995. Issued in Renton, Washington, on April 25, 1995. James V. Devany, Acting Manager, Transport Airplane Directorate, Aircraft Certification Service.
