Compliance

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 2025-0011, dated January 10, 2025 (EASA AD 2025-0011).
Unsafe condition
This AD was prompted by a design review that determined that the interval of the pressure regulator and shut-off valve (PRSOV) functional test must be reduced to meet the design safety objectives, due to a risk of dormant failures. The FAA is issuing this AD to address this dormant failure, which in combination with the icing conditions could result in loss of control of the airplane.
Affected ADs
None.
