FAA 2024-02-04

Supersedes AD 2021–13–07, which required recalculating the life and replacement, if necessary, of critical parts. The AD also required replacing a certain compressor case. Since the FAA issued AD 2021–13–07, the manufacturer published airworthiness limitations with calculations for the life of critical parts addressed by the AD. This AD continues to require the replacement of a certain centrifugal compressor case, includes an additional part number as an option for the replacement, and limits the applicability of this AD.
