REGULATORY TEXT:   86-10-02 R1 CANADAIR, LTD.: Amendment 39-5310 as revised by Amendment 39-6437. Docket No. 89-NM-127-AD.

Applicability: Model CL-600-1A11 series airplanes, all serial numbers; Model CL-600- 2A12 series airplanes, all serial numbers; and Model CL-600-2B16 series airplanes, Serial Numbers 5001 through 5033; certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To ensure that flutter does not occur in the event of failure of two hydraulic systems, accomplish the following:

A. Within 100 flight hours after June 2, 1986 (the effective date of Amendment 39- 5310), inspect the aileron and elevator flutter dampers, replenish the hydraulic fluid, or replace the damper, if necessary, in accordance with Canadair Alert Wire TA600-000-032/194, Revision 1, dated November 21, 1985.

1. Dampers, P/N 600-75135-5 and 600-75134-9, with more than .030 inch of green stripe showing, are serviceable and may remain in service until the next inspection required by this AD.

2. Dampers, P/N 600-75135-3 and 600-75134-7, with more than .040 inch of green stripe showing, are serviceable and may remain in service until the next inspection required by this AD.

3. Dampers having less green stripe showing than specified in paragraphs A.1. and A.2., above, must be replenished prior to further flight, in accordance with paragraph 3.3. of the Canadair Alert Wire.

4. Dampers having the green stripe entirely covered by the red cup must be replenished prior to further flight, in accordance with paragraph 3.4. of the Canadair Alert Wire, provided that no more than one flutter damper in this condition is fitted to the same control surface. If more than one flutter damper on any control surface is in this condition, prior to further flight, replace it with either a new flutter damper or one which is serviceable under the conditions specified in paragraph A.1., A.2., or A.3., above.

B. Repeat the procedures required by paragraphs A., above, as follows:

1. At intervals not to exceed 200 flight hours or six months, whichever occurs first, for dampers, Part Numbers (P/N) 600-75134-7 and 600-75135-3, that indicated green at the last inspection.

2. At intervals not to exceed 100 flight hours or 3 months, whichever occurs first, for dampers, P/N 600-75134-7 and -9, and P/N 600-75135-3 and -5, that indicated completely red at the last inspection.

3. At intervals not to exceed 300 flight hours or 12 months, whichever occurs first, for dampers, P/N 600-75134-9 and 600-75135-5, that indicated green at the last inspection.

C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, New York Aircraft Certification Office, FAA, New England Region.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, New York Aircraft Certification Office, FAA, New England Office.

D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Canadair, Ltd., P.O. Box 6087, Montreal, Quebec H3C 3G9, Canada. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or the New York Aircraft Certification Office, 181 South Franklin Avenue, Valley Stream, New York.
