2010-23-14 Bombardier, Inc: Amendment 39-16503. Docket No. FAA-2010- 0223; Directorate Identifier 2009-NM-105-AD. Effective Date (a) This airworthiness directive (AD) becomes effective December 22, 2010. Affected ADs (b) None. Applicability (c) This AD applies to the Bombardier, Inc. airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category. (1) Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, serial numbers 7003 through 8089 inclusive; (2) Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, serial numbers 10003 through 10265 inclusive; and (3) Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers 15001 through 15173 inclusive. Subject (d) Air Transport Association (ATA) of America Code 52: Doors. Reason (e) The mandatory continuing airworthiness information (MCAI) states: Several cases of corrosion in lower structural members of the passenger door have been reported. It was subsequently determined that a drainage ramp (constructed from resin) had deteriorated with time and was retaining moisture. The ramp, therefore, requires removal, both to prevent further corrosion and to allow full access to the door structure during future scheduled inspections. Corrosion left undetected could eventually affect the structural integrity of the door and surrounding structure. The required actions include a general visual inspection for corrosion and damage of the lower inner section of the door, repair if necessary, and application of corrosion inhibitor compound. Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Actions (g) Before the accumulation of 15,000 total flight hours, or within 5,000 flight hours after the effective date of this AD, whichever occurs later, do the actions specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD. (1) Remove the lower passenger door ramp, in accordance with the applicable Bombardier modification summary package specified in Table 1 of this AD. (2) Do a general visual inspection for any damage and corrosion behind the drainage ramp in the lower portion of the passenger door. If any damage or corrosion is found, before further flight repair in accordance with a method approved by the Manager, New York Aircraft Certification Office, FAA; or Transport Canada Civil Aviation (TCCA) (or its delegated agent). (3) Apply corrosion inhibitor compound, in accordance with the applicable Bombardier modification summary package specified in Table 1 of this AD.

This AD requires both actions. 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), ANE-170, 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: Program Manager, Continuing Operational Safety, FAA, New York ACO, 1600 Stewart Avenue, Suite 410, Westbury, New York 11590; telephone 516- 228-7300; 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 (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
