Applicability*9
This AD applies to Airbus SAS airplanes identified in paragraphs (c)(1) and (2) of this AD, certificated in any category, modified in accordance with FAA Supplemental Type Certificate (STC) ST04038NY. (1) Model A330-201, -202, -203, -223, and -243 airplanes. (2) Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes.
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 2025-0047, dated February 20, 2025 (EASA AD 2025-0047).
Unsafe condition
This AD was prompted by a finding that, for airplanes with a flightcrew oxygen system supplied by a single oxygen cylinder, the oxygen supply would not be sufficient under all circumstances for extended operations (ETOPS) with a maximum diversion time of 180 minutes (ETOPS-180) with four flightcrew members. The FAA is issuing this AD to limit ETOPS-180 operations to three flightcrew members on airplanes with a flightcrew oxygen system supplied by a single oxygen cylinder and to address incorrect minimum oxygen dispatch pressure information in the airplane flight manual supplement (AFM-S). The unsafe condition, if not addressed, could result in insufficient oxygen supply in emergency situations during ETOPS-180 operation with four flightcrew members.
Affected ADs
None.
