Models named: A320-251N, -271N, A321-251N, -253N, -272N. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all Airbus SAS Model A320-251N and -271N airplanes, and Model A321-251N, -253N, -271N, and -272N airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

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 2019-0094, dated April 26, 2019 (“EASA AD 2019-0094”).

Unsafe condition

This AD was prompted by reports that the regulated bleed temperature was measured above the design target with a temperature regulation shift phenomenon, and investigation results show that incorrect temperature regulation can degrade pneumatic system components located downstream of the pre-cooler. The FAA is issuing this AD to address this condition, which, if not corrected, could lead to hot air leakage and consequent bleed loss, possibly resulting in the reduction of the system equipment safety margin.

Affected ADs

None.
