Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbojet En ~ 

AGENCY: Federal Aviation Administration (FAA), DOT. u 

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]. 

ADDRESSES: The Docket Operations office is located at Docket Management Facility,

FYI: Regarding changes to 12-NE-28 & 12-NE-31 -~-

Hi Vince, 

I am sending this email to you FYI. 

These two sister ADs are on grid. 

In both cases, you concurred to Version 3.1 

Final grid review here has discovered the same two issues in each AD. 

Our changes are highlighted in yellow. 

In both ADs, we have: 

03/06/2013 03:58PM 

03/06/201 3 02:37:27 PM 

--Added a sentence in Comments to explain the difference in compliance between final rule and NPRM 

(i.e., removal of reporting requirement). 

--Clarified the compliance wording regarding "all" in "replace all bolts." 

I intend to continue these ADs on grid to final signature. 

Note: These ADs are at 39 and 34 days, respectively. 

Thanks.

Final Rule --Version 3.1 

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.
