Airworthiness Directive · Amendment 39-21231 · Fuel
Airbus SAS Airplanes
This AD applies to all of the Airbus SAS airplanes, certificated in any category, specified in paragraphs (c)(1) through (3) of this AD.
(1) Model A319-151N and -153N airplanes.
(2) Model A320-251N, -252N, and -253N airplanes.
(3) Model A321-251N, -252N, -253N, -251NX, -252NX, and -253NX airplanes.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A319-151N and -153N; A320-251N, -252N, and -253N; and A321-251N, -252N, -253N, -251NX, -252NX, and -253NX airplanes. This AD was prompted by a report indicating that Kathon FP 1.5 biocide added to fuel and running through an airplane's engines can lead to engine performance degradation. This AD requires removing Kathon FP 1.5 biocide from the fuel tanks and engines and prohibits operation of an airplane with Kathon FP 1.5 biocide in a fuel tank or engine, as specified in a European Union Aviation Safety Agency (EASA) AD 2020- 0176, 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, European Union Aviation Safety Agency (EASA) AD 2020-0176, dated August 5, 2020 (“EASA AD 2020-0176”).
(1) Where EASA AD 2020-0176 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2020-0176 does not apply to 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.
