This AD applies to the Bombardier, Inc. airplanes specified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category.
(1) Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, serial numbers 10303 through 10333 inclusive.
(2) Model CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers 15257 through 15284 inclusive.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a report that certain parts of the aft baggage door did not conform to the design specifications and were of degraded strength. This AD requires repetitive inspections for cracking and deformations of certain stop fittings and striker plates of the aft baggage bay door; and replacement, which would terminate the repetitive inspections. We are issuing this AD to prevent cracking and deformations of certain stop fittings and striker plates, which could result in the opening of the aft baggage bay door and rapid decompression or reduced controllability of the airplane.
Within 600 flight hours or 6 months after the effective date of this AD, whichever occurs first: Do a detailed visual inspection for cracking and deformations of the stop fittings and striker plates of the aft baggage bay door, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-52-037, Revision B, dated September 16, 2013. Repeat the inspection thereafter at intervals not to exceed 2,000 flight hours or 12 months, whichever occurs first, until the terminating action specified in paragraph (h) of this AD has been accomplished. If a crack or deformation is found on a stop fitting or striker plate, before further flight, replace the affected fittings and striker plates, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-52-037, Revision B, dated September 16, 2013.
Within 6,000 flight hours or 36 months, whichever occurs first, after the effective date of this AD: Replace the affected stop fittings and striker plates, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-52-037, Revision B, dated September 16, 2013. Replacement of the affected stop fittings and striker plates of the aft baggage bay door constitutes terminating action for the repetitive inspections required by paragraph (g) of this AD.
