Airworthiness Directive · Amendment 39-16603 · Wings
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 and 440) Airplanes
This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 and 440) airplanes; certificated in any category; serial numbers 7003 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:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 30 days after the effective date of this AD, revise the Airworthiness Limitations section (ALS) of the maintenance program by incorporating Task C36-20-133-03 specified in Bombardier Temporary Revision (TR) 2A-50, dated November 17, 2009; and Task C30-10-133-01 specified in Bombardier TR 2A-49, dated November 17, 2009; into Appendix A, “Certification Maintenance Requirements,” of Part 2 of the Bombardier CL-600-2B19 Maintenance Requirements Manual (MRM). For these tasks, the initial compliance time starts at the applicable time specified in paragraphs (g)(1) and (g)(2) of this AD. Thereafter, except as provided by paragraph (h) of this AD, no alternative functional check of the thermal switch or detailed visual inspection of the piccolo tube may be approved.
Note 1: The actions required by paragraph (g) of this AD may be done by inserting a copy of Bombardier TR 2A-49 and TR 2A-50, both dated November 17, 2009, into the Appendix A of Part 2 of the Bombardier CL-600-2B19 MRM. When these TRs have been included in Appendix A of Part 2 of the general revisions of the MRM, the general revisions may be inserted in the MRM, provided that the relevant information in the general revision is identical to that in Bombardier TR 2A-49 and TR 2A-50, both dated November 17, 2009.
(1) For Task C36-20-133-03, the initial compliance time is before the accumulation of 15,000 total flight hours or within 7 months after the effective date of this AD, whichever occurs later.
(2) For Task C30-10-133-01, the initial compliance time is before the accumulation of 15,000 total flight hours on the piccolo tube or within 7 months after the effective date of this AD, whichever occurs later.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
