Unsafe Condition
Possible loss of normal braking could lead to unsafe conditions during takeoff and landing operations.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Revise flight manual operating procedures to reduce V1 by 10 KIAS (not below 105 KIAS), increase takeoff distances by 20%, and landing distances by 65%. Within 50 flights after September 9, 1982, modify the anti-skid system per Canadair Service Bulletin A600-0212. Address suspected braking issues by manually controlling brakes as per AFM paragraph 35.3.

ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 82-09-51 R1 CANADAIR: Amendment 39-4452. Applies to all Canadair CL-600 airplanes certificated in all categories. Because of the possible loss of normal braking, accomplish the following unless already accomplished. 1. Revise flight manual operating procedures as follows before further flight: A. The critical engine failure recognition speed V1 shown in Section 4, page 4-39; Supplement 2, page S2-69; or Supplement 6, page S6-74 of the airplane flight manual shall be reduced by 10 KIAS but shall not be lower than 105 KIAS (VMCG). B. The takeoff distances derived from Section 4, page 4-44; Supplement 2, page S2-73; or Supplement 6, page S6-80 of the airplane flight manual shall be increased by a factor of 1.2 (20 percent). C. The landing distances derived from Section 4, page 4-63; Supplement 2, page S2-94; or Supplement 6, page S6-101 of the airplane flight manual shall be increased by a factor of 1.65 (65 percent). 2. If any suspected braking deficiency occurs during the brake operation, immediately release brakes, switch off the anti-skid system, and control the brakes manually as described in paragraph 35.3 of Section 2 of the airplane flight manual. 3. Within the next 50 flights after the effective date of this AD, modify the anti-skid system in accordance with Canadair Service Bulletin A600-0212 dated May 1, 1982. Accomplishment of this modification constitutes terminating action for this AD and authorizes removal of the airplane Flight Manual revisions imposed by item 1. above. 4. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Chief, Seattle Area Aircraft Certification Office, FAA Northwest Mountain Region. 5. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD. The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). This amendment becomes effective September 9, 1982, and was effective earlier to all recipients of telegraphic AD T82-09-51 dated April 14, 1982. FOOTER:
