Revises AD 93- 16-06 R1, amendment 39-8826. Applicability: Model CL-215-1A10 series airplanes that are not equipped with powered ailerons; and Model CL-215-6B11 series airplanes that are not equipped with powered ailerons; 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) of this AD 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 potential flutter of the rudder-aileron interconnect tab, which could result in reduced controllability of the airplane, accomplish the following: (a) For Model CL-215-1A10 series airplanes, serial numbers 1001 through 1125 inclusive, that are not equipped with powered ailerons: Within 12 months after October 4, 1993 (the effective date of AD 93-16-06, amendment 39-8663), on the right wing install weights to the aileron balance weight mounting channel and install washers to the interconnect tab mass balance arms, in accordance with Canadair Alert Service Bulletin 215-A435, dated August 14, 1990. (b) For all other Model CL-215-1A10 series airplanes that are not equipped with powered ailerons and are not subject to paragraph (a) of this AD: Within 12 months after March 1, 1994 (the effective date of AD 93-16-06 R1, amendment 39-8826), on right wing install weights to the aileron balance weight mounting channel and install washers to the interconnect tab mass balance arms, in accordance with Canadair Alert Service Bulletin 215-A435, dated August 14, 1990. (c) For Model CL-215-6B11 series airplanes that are not equipped with powered ailerons: Within 12 months after the effective date of this AD, on the right wing install weights to the aileron balance weight mounting channel and washers to the interconnect tab mass balance arms, in accordance with Canadair Alert Service Bulletin 215-A435, dated August 14, 1990. (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, New York Aircraft Certification Office (ACO), FAA, Engine and Propeller Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, New York ACO. NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the New York ACO. (e) 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. (f) The installation shall be done in accordance with Canadair Alert Service Bulletin 215-A435, dated August 14, 1990. The incorporation by reference of this document was approved previously by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51 as of October 4, 1993 (58 FR 46766, September 3, 1993).
