Airworthiness Directive · Amendment 39-21625 · Fuselage
Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
This AD applies to Airbus Canada Limited Partnership (type certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 airplanes, certificated in any category, as identified in Transport Canada Civil Aviation (TCCA) AD CF-2020-42, issued October 16, 2020 (TCCA AD CF-2020-42).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by reports of corrosion on the waste box, waste access doubler, and waste service door of the rear fuselage due to contamination from waste valve leakage. This AD requires an inspection for corrosion of the waste box, waste access doubler, and waste service door, and corrective actions if necessary, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, TCCA AD CF-2020-42.
Where TCCA AD CF-2020-42 specifies a compliance time of “Within 14,200 flight cycles or 56 months from the aeroplane date of manufacture, as identified on the identification plate of the aeroplane” or “Within 9,900 flight cycles or 56 months from the aeroplane date of manufacture, as identified on the identification plate of the aeroplane,” depending on airplane configuration, to accomplish all applicable actions, this AD requires that corrosion repair be done before further flight after detection of corrosion, as identified in the applicable service information specified in TCCA AD CF-2020-42.
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.
