Applicability*9
Model 1125 Westwind Astra series airplanes, as listed in IAI Service Bulletin SB 1125-53-135, dated April 26, 1995; 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. [[Page 25833]] 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 movement of the support beam attached to the fuselage frame at station 452.00, which could restrict movement of the elevator and rudder controls, and consequently lead to reduced controllability of the airplane, accomplish the following: (a) Within 50 hours time-in-service after the effective date of this AD, conduct a visual inspection to detect loose or damaged (``fretted'') rivets that fasten the support beam to the fuselage frame at station 452.000, in accordance with Part A of IAI Service Bulletin SB 1125-53-135, dated April 26, 1995. (1) If no loose or fretted rivet is detected, repeat this inspection thereafter at intervals not to exceed 250 hours time-in- service until the modification required by paragraph (b) of this AD is accomplished. (2) If any loose or fretted rivet is detected, prior to further flight, modify the support beam in accordance with Part B of IAI Service Bulletin SB 1125-53-135, dated April 26, 1995. After this modification is accomplished, no further action is required by paragraph (a) or (b) of this AD. (b) Within 500 hours time-in-service after the effective date of this AD, modify the support beam in accordance with Part B of IAI Service Bulletin SB 1125-53-135, dated April 26, 1995. Accomplishment of this modification constitutes terminating action for the repetitive inspections required by paragraph (a)(1) of this AD. (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, Standardization Branch, ANM-113, 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, Standardization Branch, ANM-113. Note 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (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 inspections and modification shall be done in accordance with IAI Service Bulletin SB 1125-53-135, dated April 26, 1995. 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.
