As Amended by 64 FR 52221
99-20-08 McDonnell Douglas: Amendment 39-11338. Docket 99-NM-216-AD.
Applicability: All Model MD-11 series airplanes, 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 request approval for an alternative method of compliance in accordance with paragraph (b) 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.
Compliance: Required as indicated, unless accomplished previously.
To prevent possible confusion as the flight-crew performs their duties in response to a smoke/fumes emergency, which could subsequently impair their ability to correctly identify the source of the smoke/fumes, and subsequently affect the continued safe flight and landing of the airplane, accomplish the following:
(a) As of the effective date of this AD, no person shall install on any airplane an In-Flight Entertainment Network (IFEN) in accordance with data approved by Supplemental Type Certificate (STC) ST00236LA-D, dated November 19, 1996; Amendment 1, dated December 18, 1996; Amendment 2, dated January 24, 1997; Amendment 3, dated February 3, 1997; Amendment 4, dated March 11, 1997; or Amendment 5, dated August 7, 1997.
Alternative Methods of Compliance
(b) 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. 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 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Los Angeles ACO.
Special Flight Permits
(c) 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.
(d) This amendment becomes effective on October 13, 1999.
