ACTION: Final rule . 

### SUMMARY: We are adopting a new airworthiness directive (AD) for certain RollsRoyce Deutschland Ltd & 

### Co KG (RRD) Spey 511-8 turbojet engines. This AD requires inspection and , if necessary , replacement of affected bolts and , if any bolt is found broken , inspection of the adjacent disc(s) for damage. This AD was prompted by a recent quality review determination that bolts with reduced material properties may have been installed in some engines. We are issuing this AD to prevent uncontained turbine disc fracture and damage to the airplane. 

### DATES: This AD becomes effective [Insert date 35 days after date of publication in the FEDERAL REGISTER].

. 1

Please see Version 3.1, attached for your review I concurrence. We've addressed the comment you made earlier on this AD
. Also, as this AD had similar compliance paragraphs to another Fred Zink AD (12-NE-31) that you recently reviewed , we've reworked those paragraphs here to coincide with the feedback you provided on that AD
. I believe you would have given the same feedback here , except you didn't get that far in your earlier review
. In particular , we've adopted a more active voice in the compliance, and eliminated the reporting requirement and the PRA paragraph
. Changes are highlighted in yellow (except the reporting requirement and deleted PRA para-- they're gone). Thanks. --Drexel
