Plain English Summary

4/10 complexity

This Airworthiness Directive applies to Allison 250‑C30, C30P and C30S engines/turbine assemblies and legally requires immediate compliance with the technical requirements of CEB‑A‑72‑3056, Revision 3. Revision 3 widens affected models and adds inspections and parts‑life limits, so operators must update maintenance and records and comply upon receipt; the earlier FAA AD alone may not suffice.
