Applicability*9
Model 747-100, -200, and -300 series airplanes; as listed in Boeing Alert Service Bulletin 747-33A2252, dated August 1, 1996, as revised by Boeing Notice of Status Change 747-33A2252 NSC 01, dated October 10, 1996; certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise 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.
Compliance
Required as indicated, unless accomplished previously. To prevent the installation and use of switches in the cabin attendant's panel that could short circuit when they fail, and consequently cause fire and smoke aboard the airplane, accomplish the following: (a) Within 10 months after the effective date of this AD, remove switches S4 and/or S5, or switches S7 and S8, that are installed in the cabin attendant's panel at door 4 right, and the equivalent switches at door 2 right, and replace them with new switches in accordance with the procedures specified in Boeing Alert Service Bulletin 747-33A2252, dated August 1, 1996, as revised by Boeing Notice of Status Change 747-33A2252 NSC 01, dated October 10, 1996.

(b) As of the effective date of this AD, no person shall install at door 2 right or at door 4 right of any airplane an attendant's panel having switch part numbers identified in the ``Old Switch'' column of any table contained in Boeing Alert Service Bulletin 747- 33A2252, dated August 1, 1996, as revised by Boeing Notice of Status Change 747-33A2252 NSC 01, dated October 10, 1996. (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, 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 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO. (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. (e) The replacement shall be done in accordance with Boeing Alert Service Bulletin 747-33A2252, dated August 1, 1996, as revised by Boeing Notice of Status Change 747-33A2252 NSC 01, dated October 10, 1996.
