Airworthiness Directive · Amendment 39-22640 · Oxygen
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes, certificated in any category, with serial numbers as identified in the Bombardier Service Bulletin 604-35-008, Revision 02, dated January 13, 2023.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This AD was prompted by a report that some airplanes were delivered without a portable protective breathing equipment (PBE) device located in the left-side forward wardrobe, flight deck, or passenger cabin area of the airplane. This AD requires visually inspecting the forward left side cabin area of the airplane to determine if the portable PBE device is installed and, if not installed, requires installing the portable PBE device along with the associated placard. The FAA is issuing this AD to address the unsafe condition on these products.
Within 12 months from the effective date of this AD, do a general visual inspection of the left-side forward wardrobe, flight deck, or passenger cabin area of the airplane and verify if a portable PBE device, marked with Technical Standard Order (TSO) C116 or C116a, is installed and placarded, in accordance with paragraph 2.B.(1) of the Accomplishment Instructions of Bombardier Service Bulletin 604-35-008, Revision 02, dated January 13, 2023. If the PBE device is missing, before further flight, install a portable PBE device marked with TSO C116 or TSO C116a and its associated placard, in accordance with paragraph 2.B.(2) of the Accomplishment Instructions of Bombardier Service Bulletin 604-35-008, Revision 02, dated January 13, 2023.
