Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
This AD applies to Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category; as identified in Bombardier Alert Service Bulletin A601R-35-014, dated September 25, 2003; and Bombardier Service Bulletin 601R-35-016, dated September 8, 2005.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires inspecting for discrepancies of the activation mechanism of certain chemical oxygen generators, and corrective action if necessary. This AD results from several incidents, on certain airplane models, of incorrect installation of the release pin into the safety pin hole of the activation mechanism of the chemical oxygen generator; this resulted in failure to activate the chemical oxygen generator when required. A separate incident occurred on a different airplane model during deployment of the cabin oxygen system, which resulted in failure of the release pin to activate the oxygen generator at a flight attendant station. We are issuing this AD to prevent failure of the activation mechanism of the chemical oxygen generator, which could result in the unavailability of supplemental oxygen and possible incapacitation of passengers and cabin crew during an in-flight decompression.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Do the detailed inspections for discrepancies of certain chemical oxygen generators of each flight attendant and lavatory oxygen panel, as applicable, and each passenger service unit of the passenger oxygen system, as specified in paragraphs (f)(1) and (f)(2) of this AD, as applicable.
(1) For airplanes identified in paragraph 1.A. of Bombardier Alert Service Bulletin A601R-35-014, dated September 25, 2003: Within 550 flight hours after the effective date of this AD, do a one-time inspection for correct alignment and engagement of the release pin with the lanyard tube in the mask container module of the activation (firing) mechanism in the chemical oxygen generator by doing all the actions, including all applicable corrective actions, in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin A601R-35-014, dated September 25, 2003. Do all applicable corrective actions before further flight.
(2) For airplanes identified in paragraph 1.A. of Bombardier Service Bulletin 601R-35-016, dated September 8, 2005: Within 1,100 flight hours after the effective date of this AD; do a one-time inspection for correct installation of the release pin of the activation mechanism of the chemical oxygen generator, by doing all the actions, including all applicable corrective actions, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R-35-016, dated September 8, 2005. Do all applicable corrective actions before further flight.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
Note 2: Bombardier Service Bulletin 601R-35-016, dated September 8, 2005, refers to B/E Aerospace Service Bulletin 117003-35-4, dated March 29, 2001, as an additional source of service information for accomplishing the inspection and corrective action specified in paragraph (f) 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.
