Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
Superseded. A later AD replaced this one: AD 2010-14-03. Comply with the one in force.
This AD applies to Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes; certificated in any category; having serial numbers (SNs) 7305 through 7990, and 8000 and subsequent.
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:
Unless already done, do the following actions.
(1) For airplanes having serial number (SN) 7305 through 7990 and 8000 through 8083: Within 12 months after the effective date of this AD, inspect the SN of the installed ADG. A review of airplane maintenance records is acceptable in lieu of this inspection if the serial number of the ADG can be conclusively determined from that review.
(i) If the serial number is not listed in paragraph 1.A of Bombardier Service Bulletin 601R-24-113, Revision A, dated August 11, 2005, no further action is required by this paragraph.
(ii) If the serial number is listed in paragraph 1.A of Bombardier Service Bulletin 601R-24-113, Revision A, dated August 11, 2005, within 12 months after the effective date of this AD, inspect the ADG identification plate and, as applicable, do the actions of paragraph (f)(1)(ii)(A) or (f)(1)(ii)(B) of this AD.
(A) If the identification plate is marked with the symbol “24-2,” no further action is required by this paragraph.
(B) If the identification plate is not marked with the symbol “24-2,” modify the ADG wiring in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R-24-113, Revision A, dated August 11, 2005.
(2) For airplanes having SN 7305 through 7990, and 8000 and subsequent: As of the effective date of this AD, no ADG as described in Table 1 of this AD may be installed on any airplane, unless the identification plate of the ADG is identified with the symbol “24-2.”
Note 1: Bombardier Service Bulletin 601R-24-113, Revision A, dated August 11, 2005, refers to Hamilton Sundstrand Service Bulletin ERPS10AG-24-2, dated February 19, 2004, for further information on identifying the symbol “24-2.”

|---|---|
| 604-90800-1 (761339C), 604-90800-17 (761339D), or 604-90800-19 (761339E) | 0101 through 0132, 0134 through 0167, 0169 through 0358, 0360 through 0438, 0440 through 0456, 0458 through 0467, 0469, 0471 through 0590, 0592 through 0597, 0599 through 0745, 0747 through 1005, or 1400 through 1439. |
(3) Actions done before the effective date of this AD according to Bombardier Service Bulletin 601R-24-113, dated April 22, 2004, are considered acceptable for compliance with the corresponding actions specified in this AD, provided the ADG has not been replaced since those actions were done.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
