Airworthiness Directive · Amendment 39-21021 · Equipment/furnishings
Bombardier, Inc. Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1) through (4) of this AD, certificated in any category, all serial numbers.
(1) Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes.
(2) Bombardier, Inc., Model CL-600-2D15 (Regional Jet Series 705) airplanes.
(3) Bombardier, Inc., Model CL-600-2D24 (Regional Jet Series 900) airplanes.
(4) Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes.
The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., 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. This AD was prompted by a report of incorrectly installed flight compartment door edge protection plates on both sides of the upper decompression panel. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate a functional check of the flight compartment door decompression latches. The FAA is issuing this AD to address the unsafe condition on these products.
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 251700-202, “Functional Check of the Flight Compartment Door Decompression Latches,” of Section 1, “Systems and Power Plant Program,” Subject 1-25, “Equipment and Furnishings,” of the Bombardier Model CL-600-2C10, CL-600-2D15, CL-600-2D24, and CL-600-2E25 Series 700/705/900/1000 Maintenance Review Board Report, Maintenance Requirements Manual—Part 1, Volume 1, CSP B-053, Revision 18, dated July 25, 2018. The initial compliance time for doing the task is within 8,000 flight hours after this task is incorporated into the existing maintenance or inspection program, or within 30 days after the effective date of this AD, whichever occurs later. Repeat the task thereafter at intervals not to exceed 8,000 flight hours.
After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions and intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
