Compliance

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

Required actions

Except as specified in paragraphs (h), and (i) of this AD: Perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency AD 2024-0178, dated September 12, 2024 (EASA AD 2024-0178).

Unsafe condition

This AD was prompted by reports of cracked intermediate pressure compressor (IPC) shaft assembly front air seals. The FAA is issuing this AD to prevent an IPC stage 1 disk burst or failure of the IPC front seal. The unsafe condition, if not addressed, could result in an IPC stage 1 disk burst with consequent release of high energy debris and damage to the airplane or failure of the IPC front seal and release of debris, which could lead to an engine in-flight shutdown (IFSD) and in the case of a dual IFSD could result in reduced control of the airplane.

Affected ADs

None.
