SUMMARY: The FAA is superseding airworthiness directive (AD) 2018-13-07 for the engines listed above.
AD 2018-13-07 required initial inspections of the intermediate-pressure compressor (IPC) stage 1 rotor blades, IPC stage 2 rotor blades, and IPC shaft stage 2 dovetail posts, and removing any cracked parts from service.
This AD requires initial inspections and adds repetitive inspections of the IPC stage 1 rotor blades, IPC stage 2 rotor blades, and IPC shaft stage 2 dovetail posts, and removing any cracked parts from service.
This AD was prompted by the manufacturer determining the need for repetitive inspections of the IPC stage 1 rotor blades, IPC stage 2 rotor blades, and IPC shaft stage 2 dovetail posts.

COST: The FAA estimates that this AD affects 0 engines installed on airplanes of U.S. registry. Future operators may incur the following costs in order to comply with this AD:
- Inspect IPC blades and dovetail post - 20 work-hours × $85 per hour = $1,700.
- Replace IPC Stage 1 Rotor blade - 0 work-hours × $85 per hour = $0. Parts - $1,528. Cost per engine - $1,528
- Replace IPC Stage 2 Rotor blade - 0 work-hours × $85 per hour = $0 Parts - $993. Cost per engine - $993
- Replace IPC 1-8 drum - 0 work-hours × $85 per hour = $0 Parts - $1,365,219 Cost per engine - $1,365,219
