AD 2008-01-04 Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

This AD applies to Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, serial numbers 7003 through 7990 and 8000 and subsequent.

Unless already done, do the following actions. (1) As of November 30, 2008, no affected airplane may be operated unless the flight crewmembers of that airplane have received simulator training on reduced or zero flap landing that is acceptable to the POI. Thereafter, this training must be done during the normal simulator training cycle, at intervals not to exceed 12 months. (2) Within 24 months or 4,000 flight hours after the effective date of this AD, whichever occurs first: Do a pressure test of the flexible drive-shaft, and do all applicable corrective actions, by doing all the applicable actions specified in “PART B” of the Accomplishment Instructions of Bombardier Service Bulletin 601R-27-150, dated July 12, 2007. Do all applicable corrective actions before further flight. (3) For airplanes having flap actuators, part numbers (P/Ns) 852D100-19/-21, 853D100-19/-20, and 854D100-19/-20, specified in paragraphs (g)(3)(i) and (g)(3)(ii) of this AD: Within 24 months after the effective date of this AD, do a low temperature torque test of the flap actuators, and do all applicable corrective actions, by doing all the applicable actions specified in “PART C” of the Accomplishment Instructions of Bombardier Service Bulletin 601R-27-150, dated July 12, 2007. Do all applicable corrective actions before further flight. (i) Airplanes having actuators that have not been repaired and that have accumulated more than 2,000 flight hours since new. (ii) Airplanes having actuators that have been repaired and that have accumulated more than 2,000 flight hours on the inboard pinion shaft seals, P/Ns 853SC177-1/-2. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: (1) The maintenance tasks specified in the first row of the table in “Part IV. Maintenance Actions” of the MCAI do not specify a corrective action if an actuator is not serviceable ( i.e. , torque test results are not satisfactory). However, this AD requires contacting the FAA or installing a serviceable actuator before further flight if torque test results are not satisfactory. (Reference paragraph (f)(4) of this AD.) (2) Although paragraph 2. of “Part III. Training” of the MCAI recommends accomplishing the initial training within 1 year, this AD requires accomplishing the training before November 30, 2008, in order to ensure that the actions are completed prior to the onset of cold weather operations. (3) The MCAI does not specify which actuators are applicable to the actions specified in “Part C” of Bombardier Service Bulletin 601R-27-150, dated July 12, 2007. This AD requires that “Part C” of the service bulletin only be done for the actuators specified in paragraph (g)(3) of this AD. Other FAA AD Provisions (h) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, New York Aircraft Certification Office (ACO), 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: Dan Parrillo, Aerospace Engineer, Systems and Flight Test Branch, ANE-172, FAA, New York ACO, 1600 Stewart Avenue, Suite 410, Westbury, New York 11590; telephone (516) 228-7305; fax (516) 794-5531. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. AMOCs approved previously in accordance with AD 2007-17-07 are approved as AMOCs for the corresponding provisions of 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. Related Information (i) Refer to MCAI Canadian Airworthiness Directive CF-2007-10, dated July 18, 2007; Bombardier Service Bulletin 601R-27-150, dated July 12, 2007; and Canadair Regional Jet Temporary Revision RJ/165, dated July 6, 2007, to the Canadair Regional Jet Airplane Flight Manual CSP A-012; for related information. Material Incorporated by Reference (j) You must use Bombardier Service Bulletin 601R-27-150, including Appendix A, dated July 12, 2007; and Canadair Regional Jet Temporary Revision RJ/165, dated July 6, 2007, to the Canadair Regional Jet Airplane Flight Manual CSP A-012; as applicable, to do the actions required by this AD, unless the AD specifies otherwise. (1) The Director of the Federal Register previously approved the incorporation by reference of Bombardier Service Bulletin 601R-27-150, including Appendix A, dated July 12, 2007; and Canadair Regional Jet Temporary Revision RJ/165, dated July 6, 2007, to the Canadair Regional Jet Airplane Flight Manual CSP A-012 on September 5, 2007 (72 FR 46555, August 21, 2007).
