AD 2009-10-05 Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 and 440) Airplanes

This AD applies to all Bombardier Model CL-600-2B19 (Regional Jet series 100 and 440) airplanes, certificated in any category, with serial numbers (S/Ns) 7003 and later, equipped with inboard flap actuators part number (P/N) 601R93101-21 (Eaton P/N 852D100-21) or P/N 601R93101-25 (Eaton P/N 852D100-25).

Unless already done, do the following actions. (1) Within 100 flight cycles after the effective date of this AD: Inspect the serial number of each of the flap actuators having P/N 601R93101-21 and P/N 601R93101-25 installed on the airplane. If the serial number of the inspected actuator is listed in paragraph (f)(1)(i) or (f)(1)(ii) of this AD, before further flight, replace the flap actuator with an actuator that has a serial number not listed in paragraph (f)(1)(i), (f)(1)(ii), or (f)(2) of this AD, in accordance with Section 27-53-01 of Bombardier (Canadair) Regional Jet Aircraft Maintenance Manual (AMM), CSP A-001, Revision 40, dated September 10, 2008. If any of the serial numbers found have a suffix “A,” replacement is not required. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the flap actuator can be conclusively determined from that review. (i) For P/N 601R93101-21: Serial numbers 7772, 7773, 7774, 7775, 7776, 7778, 7779, 7780, 7781, 7782, 7784, 7786, 7787, 7788, 7790, 7791, 7793, 7797, 7798, 7799, 7801, 7802, 7803, 7804, 7805, 7806, 7807, 7808, 7810, 7813, 7815, 7816, 7817, 7818, 7819, 7820, 7821, 7825, 7826, 7827, 7828, and 7829. (ii) For P/N 601R93101-25: Serial numbers 7783 and 7796. Note 1: Replacing an existing flap actuator P/N 601R93101-21 with a P/N 601R93101-25 that does not have a serial number listed in paragraph (f)(2) of this AD also satisfies the requirements of paragraph (f)(1) of this AD. (2) Within 500 flight cycles after the effective date of this AD: Inspect the serial number of each of the flap actuators P/N 601R93101-25 installed on the airplane. If the serial number is 3278, 3401, 3512, 3526, 3597, 3599, 3606, 3738, 3806, 3861, 4066, 4284, 4315, 4401, 4499, 4538, 4582, 4658, 4979, 5007, 5094, 6422, 6969, or 7867, before further flight, replace the flap actuator having P/N 601R93101-25 with a flap actuator having a serial number not identified in this paragraph or paragraph (f)(1) of this AD. Do the replacement in accordance with Section 27-53-01 of Bombardier (Canadair) Regional Jet AMM, CSP A-001, Revision 40, dated September 10, 2008. If any of the serial numbers found have a suffix “B,” replacement is not required. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the flap actuator can be conclusively determined from that review. (3) As of the effective date of this AD, replacement of a flap actuator having P/N 601R93101-21 or 601R93101-25 with a serial number identified in paragraph (f)(1)(i), (f)(1)(ii), or (f)(2) of this AD is not allowed on any airplane unless the serial number of the actuator listed in paragraph (f)(1)(i) and (f)(1)(ii) of this AD is identified with suffix “A,” and the serial number of the actuator listed in paragraph (f)(2) is identified with suffix “B.” Note 2: Serial number suffix “A” or “B” indicates that a conforming gear set has been installed. FAA AD Differences Note 3: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, New York Aircraft Certification Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Christopher Alfano, Aerospace Engineer, Airframe and Mechanical Systems Branch, ANE-171, FAA, New York Aircraft Certification Office, 1600 Stewart Avenue, Suite 410, Westbury, New York 11590; telephone (516) 228-7340; fax (516) 794-5531. Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
