Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2016– 

0242, dated December 7, 2016 (referred 

to hereinafter as ‘‘the MCAI’’), to correct 

an unsafe condition for the specified 

products. The MCAI states: 

It has recently been established that a 

certain population of low pressure (LP) 

compressor case support pins and hollow 

dowels have insufficient material properties 

and do not meet specification requirements. 

This condition, if not corrected, could result 

in loss of core to fan case concentricity, LP 

compressor blade rubs and possible blade 

release, or engine under cowl fire. To address 

this unsafe condition, RR published Alert 

NMSB TRENT XWB 72–AJ443 to provide 

instructions to inspect and replace the 

affected non-conforming components. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2017– 

0767. 

Related Service Information Under 1 

CFR Part 51 

RR has issued Alert Non-Modification 

Service Bulletin (NMSB) No. TRENT 

XWB 72–AJ443, Revision 1, dated 

December 21, 2016. The Alert NMSB 

describes procedures for replacement of 

all non-conforming LPC case support 

inboard pins. This service information 

is reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

EASA, and is approved for operation in 

the United States. Pursuant to our 

bilateral agreement with the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are issuing this 

AD because we evaluated all 

information provided by EASA and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. This 

AD requires replacement of all nonconforming LPC case support inboard 

pins. 

FAA’s Determination of the Effective 

Date 

No domestic operators use this 

product. Therefore, we find that notice 

and opportunity for prior public 

comment are unnecessary and that good 

cause exists for making this amendment 

effective in less than 30 days. 

Costs of Compliance 

We estimate that this AD affects no 

engines installed on airplanes of U.S. 

registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inboard pin replacement ......... 18 work-hours × $85 per hour = $1,530.00 ........................... $0 $1,530.00 $0 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to engines, propellers, and 

appliances to the Manager, Engine and 

Propeller Standards Branch, Policy and 

Innovation Division. 

Regulatory Findings 

We determined that this AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

not have a substantial direct effect on 

the States, on the relationship between 

the national government and the States, 

or on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 


Pmangrum on DSK3GDR082PROD with RULES
Federal Register / Vol. 82, No. 185 / Tuesday, September 26, 2017 / Rules and Regulations 44717 

(3) Will not affect intrastate aviation 

in Alaska to the extent that it justifies 

making a regulatory distinction, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

2017–19–19 Rolls-Royce plc: Amendment 

39–19049; Docket No. FAA–2017–0767; 

Product Identifier 2017–NE–26–AD. 

(a) Effective Date 

This AD is effective October 11, 2017. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Rolls-Royce plc (RR)

(d) Subject 

Joint Aircraft System Component (JASC) 

Code 7230, Turbine Engine Compressor 

Section. 

(e) Reason

compressor (LPC) case support inboard pins 

that may have reduced integrity due to 

incorrect heat treatment. We are issuing this 

AD to prevent failure of the LPC case support 

inboard pins, loss of core to fan case 

concentricity, LPC blade rubs and possible

Section 3, the Accomplishment Instructions, 

of RR Alert NMSB Trent XWB 72–AJ443, 

Revision 1, dated December 21, 2016.

NMSB Trent XWB 72–AJ443, Revision 1, 

dated December 21, 2016. 

(h) Installation Prohibition

NMSB Trent XWB 72–AJ443, Revision 1, 

dated December 21, 2016. 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, FAA, ECO Branch, 

Compliance and Airworthiness Division, has 

the authority to approve AMOCs for this AD,
