Rolls-Royce Engines Get Crack-Detecting Upgrade Mandate
Published Date: 3/19/2025
Rule
Summary
If you own certain Rolls-Royce Deutschland BR700 engines, this new rule updates how you check fan disks for cracks. It swaps old inspections for a cooler, improved ultrasonic method and lets you fix the engine to stop inspections altogether. You’ll need to act on these changes soon to keep your engines safe and flying without extra costs piling up.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Mandatory Fan‑Disk Inspections and Replacements
If you operate certain Rolls‑Royce Deutschland BR700-710A1-10, BR700-710A2-20, or BR700-710C4-11 engines, this rule requires initial and repetitive visual inspections of specified low‑pressure compressor (fan) disks and mandates replacement of any fan disk in which a crack is found.
Engine Modification Can End Inspections
The rule continues to allow modification of the engine, in accordance with Rolls‑Royce Deutschland service information and as specified in the incorporated EASA AD, to serve as a terminating action that ends the repetitive inspections of the affected fan disks.
Updated Ultrasonic Inspection Instructions
The manufacturer published updated service information and revised the engine maintenance manual to provide instructions for an improved ultrasonic inspection method for these fan disks; that change prompted this Airworthiness Directive.
