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 (d) 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.

Required as indicated, unless accomplished previously. To prevent separation of a main landing gear (MLG) wheel due to loose or missing tie-bolts or tie-bolt nuts, with consequent damage to airplane structure or systems, decompression, loss of full braking ability, or injury to personnel on the ground, accomplish the following: Inspection (a) Within 10 landings or 12 days after the effective date of this AD, whichever comes first, inspect the MLG wheels to determine the part numbers (P/Ns) of the tie-bolt nuts; per Raytheon Service Bulletin SB 32-3522, dated September 2002, excluding Service Bulletin/Kit Drawing Report Fax. Replacement (b) If any tie-bolt nut having P/N NAS1804 is found installed during the inspection required by paragraph (a) of this AD, before further flight, replace the tie-bolt nut with a new nut having P/N FN22A524, (or with a new tie-bolt nut having a Dunlop P/N H5227C-5CW, SN407C-054, or LH13318-5, which are P/Ns authorized by Raytheon); per Raytheon Service Bulletin SB 32-3522, dated September 2002, excluding Service Bulletin/Kit Drawing Report Fax. Parts Installation (c) As of the effective date of this AD, no person shall install any MLG wheel having a tie-bolt nut with P/N NAS1804, on any airplane. Alternative Methods of Compliance (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, Wichita 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, Wichita ACO. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Wichita ACO. Special Flight Permits (e) Special flight permits may be issued in accordance with §§ 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. Incorporation by Reference (f) Unless otherwise provided by this AD, the actions shall be done per Raytheon Service Bulletin SB 32-3522, dated September 2002, excluding Service Bulletin/Kit Drawing Report Fax. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
