Superseded. A later AD replaced this one: AD 2019-08-08. Comply with the one in force.
This AD applies to the Bombardier, Inc. airplanes, certificated in any category, identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD.
(1) Bombardier, Inc. Model CL-600-1A11 (CL-600) airplanes, serial numbers 1004 through 1085 inclusive;
(2) Bombardier, Inc. CL-600-2A12 (CL-601) airplanes, serial numbers 3001 through 3066 inclusive; and
(3) Bombardier, Inc. CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) airplanes, serial numbers 5001 through 5194 inclusive, 5301 through 5665 inclusive, and 5701 and subsequent.
Note 1: Some Model CL-600-2B16 (CL-604) airplanes might be referred to by the marketing designation CL-605 in the applicable service bulletins listed in Table 1 of this AD.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Do the following actions as applicable.
(1) Within 50 flight hours after the effective date of this AD, inspect to determine the part numbers of the system accumulators numbers 1, 2, and 3 and brake accumulators numbers 2 and 3 that are installed on the airplane. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the accumulator can be conclusively determined from that review. If all of the installed accumulators have P/N 2770571-102, 2770571-103, 2770571-104, or 2770571-105, no further action is required by this AD.
(2) At the applicable time in paragraph (g)(2)(i), (g)(2)(ii), or (g)(2)(iii) of this AD, replace the accumulator with a new, overhauled, or refurbished accumulator with the same part number, in accordance with the Accomplishment Instructions of the applicable service bulletin listed in Table 1 of this AD.

| CL-600-2B16 (CL-604 variant) | 604-29-008 | 02 | May 10, 2010. |
| CL-600-2B16 (CL-605) | 605-29-001 | 02 | May 10, 2010. |
(i) For each accumulator having P/Ns 08-60163-001 (601R75138-1), 08-60163-002 (601R75138-1), 08-60164-001 (601R75138-3), and 08-60164-002 (601R75138-3), as applicable, that has accumulated more than 3,650 total flight cycles as of the effective date of this AD: Replace the accumulator within 100 flight cycles after the effective date of this AD.
(ii) For each accumulator having P/N 08-60163-001 (601R75138-1), 08-60163-002 (601R75138-1), 08-60164-001 (601R75138-3), and 08-60164-002 (601R75138-3), as applicable, that has accumulated 3,650 total flight cycles or fewer as of the effective date of this AD: Replace the accumulator before the accumulation of 3,750 total flight cycles on the accumulator.
(iii) For each accumulator having P/N 08-60163-001 (601R75138-1), 08-60163-002 (601R75138-1), 08-60164-001 (601R75138-3), and 08-60164-002 (601R75138-3), as applicable, for which it is not possible to determine the number of flight cycles accumulated: Replace the accumulator within 100 flight cycles after the effective date of this AD.
(3) Thereafter, before the accumulation of 3,750 total flight cycles on any accumulator having P/Ns 08-60163-001 (601R75138-1), 08-60163-002 (601R75138-1), 08-60164-001 (601R75138-3), and 08-60164-002 (601R75138-3), as applicable, replace the accumulator with a new, overhauled, or refurbished accumulator having the same part number, in accordance with the Accomplishment Instructions of the applicable service bulletin listed in Table 1 of this AD.
Note 2: The part numbers in parentheses in paragraphs (g)(2)(i), (g)(2)(ii), (g)(2)(iii), and (g)(3) of this AD, are equivalent specification part numbers, as specified in the applicable service bulletin listed in Table 1 of this AD.
(4) Replacement of an accumulator with a new accumulator having the same part number is also acceptable for compliance with the requirements of paragraph (g)(2) of this AD, if done before the effective date of this AD in accordance with the applicable service bulletin listed in Table 2 of this AD.

Note 3: This AD differs from the MCAI and/or service information as follows: (1) The MCAI specifies that certain airplanes do not need to be inspected for the part number; however, this AD requires that inspections be done on all airplanes to determine the part number. (2) The MCAI specifies to record the number of flight cycles accumulated on each affected part. This AD does not require that operators record the number of flight cycles.
