This AD applies to the Bombardier, Inc., airplanes, certificated in any category, identified in paragraphs (c)(1) through (4) of this AD, with a Class C cargo compartment configuration.
(1) Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, serial numbers 7003 and subsequent.
(2) Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, serial numbers 10002 and subsequent.
(3) Model CL-600-2D15 (Regional Jet Series 705) airplanes and Model CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers 15001 and subsequent.
(4) Model CL-600-2E25 (Regional Jet Series 1000) airplanes, serial numbers 19001 and subsequent.
The FAA superseding Airworthiness Directive (AD) 2015-24-04, which applied to certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2015-24-04 required repetitive inspections of the cage assembly for damaged or detached window louver panel assemblies (WLPAs) and blowout panels (BOPs), and corrective actions if necessary. This AD requires one-time inspections of the WLPAs and BOPs, corrective actions if necessary, and a revision of the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations, which would terminate the inspection requirement. This AD was prompted by a determination that new airworthiness limitations, as well as additional actions, are necessary to address the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products.
(1) At the applicable time specified in paragraph (g)(1)(i) or (ii) of this AD: Do detailed inspections for damaged or detached WLPAs, and do all applicable corrective actions before further flight, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R-25-201, Revision C, dated May 11, 2017.
(i) For airplanes with the accumulation of 780 total flight hours or more as of December 15, 2015 (the effective date of AD 2015-24-04): Inspect within 100 flight hours after December 15, 2015.
(ii) For airplanes that have accumulated less than 780 total flight hours as of December 15, 2015 (the effective date of AD 2015-24-04): Inspect before accumulating 880 total flight hours after December 15, 2015.
(2) Within 30 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Task C26-25-115-01, “Detailed Inspection of the Window Louver Panel Assembly (WLPA) in Aft Cabin/Cargo Compartment Bulkhead,” provided in Bombardier CL-600-2B19 Temporary Revision (TR) 2A-69, dated August 30, 2018 (which is a TR to Appendix A—Certification Maintenance Requirements (CMR), of Part 2 of the Bombardier CL-600-2B19 Maintenance Requirements Manual (MRM), CSP-A-053). The initial compliance time for accomplishing the task is within 880 flight hours from the last inspection performed as specified in Bombardier Service Bulletin 601R-25-201, Revision C, dated May 11, 2017. Accomplishing the actions required by this paragraph terminates the inspection requirement in paragraph (g)(1) of this AD.
(1) At the applicable time specified in paragraph (h)(1)(i) or (ii) of this AD: Do detailed inspections for damaged or detached WLPAs and BOPs, and do all applicable corrective actions before further flight, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-25-100, Revision C, dated May 11, 2017.
(i) For airplanes with the accumulation of 780 total flight hours or more as of December 15, 2015 (the effective date of AD 2015-24-04): Inspect within 100 flight hours after December 15, 2015.
(ii) For airplanes that have accumulated less than 780 total flight hours as of December 15, 2015 (the effective date of AD 2015-24-04): Inspect before accumulating 880 total flight hours after December 15, 2015.
(2) Within 30 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Task 255000-208, “Detailed Inspection of the Aft Cargo Compartment Window-Louver Panel Assembly and Blowout Panels Along with Their Respective Cage Assemblies,” as specified in CRJ Series Regional Jet (Bombardier) TR MRB-0079, dated May 29, 2017 (which is a TR to Part 1 of the Bombardier CRJ Series Regional Jet MRM, CSP B-053). The initial compliance time for accomplishing the task is within 880 flight hours from the last inspection performed in accordance with Bombardier Service Bulletin 670BA-25-100, Revision C, dated May 11, 2017. Accomplishing the actions required by this paragraph terminates the inspection requirement in paragraph (h)(1) of this AD.
