Models named: BD-500-1A10, BD-500-1A11. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Airbus Canada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) airplanes, certificated in any category, identified in paragraphs (c)(1) and (2) of this AD. (1) Model BD-500-1A10 airplanes, serial numbers 50010 through 50018 inclusive, and 50020 through 50039 inclusive.

Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 1,650 flight hours or 8 months after the effective date of this AD, whichever occurs first: Do a general visual inspection of the air extraction duct installation to determine if a protective end cap is installed, and if installed, remove the protective end cap before further flight, in accordance with Step 2.2 of the Accomplishment Instructions of Airbus Canada Limited Partnership A220 Service Bulletin BD500-351004, Issue 001, dated April 8, 2020.
Unsafe condition
This AD was prompted by a report that during installation on the final assembly line, a foreign object damage (FOD) protective end cap was not removed from an extraction duct of the crew oxygen system. The protective end cap must be removed to prevent a build-up of oxygen under the flight deck floor, which is a fire risk. The FAA is issuing this AD to address this possible ignition source, which could result in an oxygen-fed fire.
Affected ADs
None.
