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 deficiencyoccurs 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. ## Affected data sheets (2) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A21EA](https://openairdocs.org/tcds/A21EA): Bombardier Inc.; names 3 of 5 models: CL-600-1A11 (600), CL-600-2A12 (601), CL-600-2B16 (604 Variant) - [TCDS A21EA-1](https://openairdocs.org/tcds/A21EA-1): MHI RJ Aviation ULC; names 1 of 9 models: CL-600-2B19 (Regional Jet Series 100) ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 1,016 (1,016 by airframe model, 0 by engine model) - Makers: Bombardier 828, Canadair 183, Bombardier Inc Canadair 2, Bombardier Aerospace 1, Canadair Bombardier 1, Mhi RJ Aviation ULC 1 Models with the most aircraft: - [Bombardier CL-600-2B19](https://openairdocs.org/model/bombardier-cl-600-2b19): 396 aircraft (airframe model) - [Bombardier CL-600-2B16](https://openairdocs.org/model/bombardier-cl-600-2b16): 388 aircraft (airframe model) - [Canadair CL-600-2B16](https://openairdocs.org/model/canadair-cl-600-2b16): 134 aircraft (airframe model) - [Bombardier CL-600-2B16(CL-604)](https://openairdocs.org/model/bombardier-cl-600-2b16-cl-604): 42 aircraft (airframe model) - [Canadair CL-600-2A12](https://openairdocs.org/model/canadair-cl-600-2a12): 19 aircraft (airframe model) - [Canadair CL-600-2B19](https://openairdocs.org/model/canadair-cl-600-2b19): 19 aircraft (airframe model) - [Canadair CL-600-1A11](https://openairdocs.org/model/canadair-cl-600-1a11): 5 aircraft (airframe model) - [Canadair CL600-2B16(CL601-3A)](https://openairdocs.org/model/canadair-cl600-2b16-cl601-3a): 3 aircraft (airframe model) - [Bombardier Inc Canadair CL-600-2B19](https://openairdocs.org/model/bombardier-inc-canadair-cl-600-2b19): 2 aircraft (airframe model) - [Canadair CL600-1A11](https://openairdocs.org/model/canadair-cl600-1a11): 2 aircraft (airframe model) - [Bombardier CL-600-2A12](https://openairdocs.org/model/bombardier-cl-600-2a12): 1 aircraft (airframe model) - [Bombardier CL600-2B16 (CL601-3A](https://openairdocs.org/model/bombardier-cl600-2b16-cl601-3a): 1 aircraft (airframe model) - [Bombardier Aerospace CL-600-2B16 (CL-604)](https://openairdocs.org/model/bombardier-aerospace-cl-600-2b16-cl-604): 1 aircraft (airframe model) - [Mhi RJ Aviation ULC CL-600-2B19](https://openairdocs.org/model/mhi-rj-aviation-ulc-cl-600-2b19): 1 aircraft (airframe model) - [Canadair Bombardier CL-600-2B16](https://openairdocs.org/model/canadair-bombardier-cl-600-2b16): 1 aircraft (airframe model) - [Canadair CL-600-2A12(CL-601)](https://openairdocs.org/model/canadair-cl-600-2a12-cl-601): 1 aircraft (airframe model) All 16 models: https://openairdocs.org/ad/82-09-51-R1/models.md Every aircraft: https://openairdocs.org/ad/82-09-51-R1/aircraft.md Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
