Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2023-0087, dated April 26, 2023 (EASA AD 2023-0087).
Unsafe condition
This AD was prompted by a determination that certain intervals for visual inspection of the intermediate-pressure stage 8 (IP8) air transfer tubes, high-pressure stage 3 (HP3) air transfer tubes, and front bearing housing IP8 air feed tubes need to be reduced. The FAA is issuing this AD to prevent failure of the IP8 and HP3 air transfer tubes and front bearing housing IP8 air feed tubes. The unsafe condition, if not addressed, could affect the engine internal cooling and sealing flows, resulting in failure of the IP8 air transfer tubes, HP3 air transfer tubes, and front bearing housing IP8 air feed tubes, with consequent damage to the engine and reduced control of the airplane.
Affected ADs
None.
