83-07-09 R1 CANADAIR: Amendment 39-8675. Docket 92-NM-231-AD. Revises AD 83-07-09, Amendment 39-4609.
Applicability: All Model CL-600-1A11 and CL-600-2A12 series airplanes, certificated in any category.
Compliance: Required as indicated, unless accomplished previously.
NOTE 1: This AD requires the same actions as required by AD 83-07-09, Amendment 39-4609, but is applicable to fewer airplanes. Operators affected by this AD who have accomplished these actions previously in accordance with AD 83-07-09 are considered to be in compliance with this revised AD.
To prevent possible wire overheating, which could result in a cabin fire, accomplish the following:
(a) Within 300 hours time-in-service or within 3 calendar months after April 13, 1983 (the effective date of AD 83-07-09, Amendment 39-4609), whichever occurs earlier, perform an inspection to verify proper installation of the 8 gage feeder wires from generators 1 and 2 and the auxiliary power unit (APU), in accordance with Canadair Drawings 600-58001, Note 17, or 600-58031, Note 14; and CL-600 Completion Centre Handbook Section 6. Prior to further flight, correct any discrepant wires in accordance with the drawings or handbook.
(b) Replacement of the 8 gage generator 1, generator 2, and APU feeder wires with 4 gage feeder wires of the same type constitutes an approved alternative method of compliance for the requirements 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, 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.
(d) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.
(e) This amendment becomes effective on November 12, 1993.
