Airworthiness Directives; Rolls-Royce

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Rolls-Royce Deutschland Ltd & Co KG 

(RRD) model Tay 650–15 turbofan 

engines. This proposed AD was 

prompted by excessive deterioration of 

the high-pressure (HP) air bleed valve 

operating mechanism. This proposed 

AD would require a one-time inspection 

of the HP air bleed valve operating 

mechanism and, depending on findings, 

corrective action. We are proposing this 

AD to prevent multiple fan blade 

failure, which could result in 

uncontained engine failure and damage 

to the airplane. 

DATES: We must receive comments on 

this proposed AD by August 12, 2013. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov and follow 

the instructions for sending your 

comments electronically.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2013–0086, 

dated April 9, 2013, to correct an unsafe 

condition for the specified products. 

That mandatory continuing 

airworthiness information (MCAI) 

states: 

A review of the service history of Tay 

engines discovered that the High Pressure 

(HP) air bleed valve operating mechanism 

could be a subject of excessive deterioration, 

influencing the aerodynamics and stability of 

the Low Pressure (LP) compressor (fan) rotor. 

This condition, if not corrected, could 

reduce fan flutter margin and, in some cases, 

could lead to multiple fan blade failures, 

possibly resulting in an uncontained release 

of high energy debris with consequent 

damage to, and/or reduced control of, the 

aeroplane. 

We are proposing this AD to prevent 

multiple fan blade failure, which could 

result in uncontained engine failure and 

damage to the airplane. You may obtain 

further information by examining the 

MCAI in the AD docket. 

Relevant Service Information 

RRD has issued Alert NonModification Service Bulletin (NMSB) 

No. TAY–75–A1784, dated February 14, 

2013. The NMSB describes procedures 

for inspection of the HP air bleed valve 

operating mechanism and corrective 

action, if necessary. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of Germany 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 proposing 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 


pmangrum on DSK3VPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 114 / Thursday, June 13, 2013 / Proposed Rules 35575 

products of the same type design. This 

proposed AD would require a one-time 

inspection of the HP air bleed valve 

operating mechanism and, depending 

on findings, corrective action. 

Costs of Compliance 

We estimate that this proposed AD 

affects 52 Tay turbofan engines installed 

on airplanes of U.S. registry. We also 

estimate that it would take about 10 

hours per engine to comply with this 

proposed AD. The average labor rate is 

$85 per hour. Required parts cost about 

$153 per product. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$52,156. 

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. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

(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); 

(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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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): 

Rolls-Royce Deutschland Ltd & Co KG 

Turbofan Engines (formerly Rolls-Royce 

plc): Docket No. FAA–2013–0397; 

Directorate Identifier 2013–NE–15–AD. 

(a) Comments Due Date 

We must receive comments by August 12, 

2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Rolls-Royce 

Deutschland Ltd & Co KG (RRD) model Tay 

650–15 turbofan engines. 

(d) Reason 

This AD was prompted by excessive 

deterioration of the high-pressure (HP) air 

bleed valve operating mechanism which 

affects the aerodynamic flutter margin, 

causing subsequent multiple fan blade 

failure. We are issuing this AD to prevent 

multiple fan blade failure, which could result 

in uncontained engine failure and damage to 

the airplane. 

(e) Actions and Compliance 

Unless already done, do the following 

actions. 

(1) Within 1,500 flight cycles after the 

effective date of this AD, perform a one-time 

inspection of the HP air bleed valve operating 

mechanism. Use paragraphs 3.D. and 3.E. of 

RRD Alert Non-Modification Service Bulletin 

(NMSB) No. TAY–75–A1784, dated February 

14, 2013, to do your inspection. 

(2) If the measured torque necessary to 

open and close the HP air bleed valve is 

higher than the torque values referenced in 

paragraph 3.D.(1)(a) of RRD Alert NMSB No. 

TAY–75–A1784, dated February 14, 2013, 

then before next flight, accomplish paragraph 

3.E. of RRD Alert NMSB No. TAY–75–A1784, 

dated February 14, 2013. 

(f) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

may approve AMOCs for this AD. Use the 

procedures found in 14 CFR 39.19 to make 

your request. 

(g) Related Information

ACTION: Notice of proposed rulemaking;

SUMMARY: Physicians and adjudicators 

use chest radiographs (X-rays) as a tool 

in evaluating whether a coal miner 

suffers from pneumoconiosis (black 

lung disease). Accordingly, the 

Department’s regulations implementing 

the Black Lung Benefits Act allow the 

submission of radiographs in 

connection with benefit claims and set 

out quality standards for their 

performance. These standards are 

currently limited to film radiographs. In 

recent years, many medical facilities 

have phased out film radiography in
