Airworthiness Directives; Rolls-Royce 

Deutschland Ltd & Co KG Turbofan 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Rolls-Royce Deutschland Ltd & Co KG 

(RRD) Tay 611–8 turbofan engines. This 

AD requires inspection and 

replacement, if necessary, of affected 

bolts. This AD was prompted by a 

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 April 

24, 2013. 

ADDRESSES: The Docket Operations 

office is located at Docket Management 

Facility, U.S. Department of 

Transportation, 1200 New Jersey

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on November 13, 2012 (77 FR 

67582). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information states: 

The results of a recent quality review of 

low pressure turbine (LPT) stage 1 static air 

seal and high pressure turbine (HPT) stage 1 

air seal support bolts identified that, before 

installation, those bolts may have not been 

inspected. As a consequence, bolts with 

reduced material properties may have been 

installed in some engines. 

This condition, if not detected and 

corrected, could lead to failure of a bolt, 

potentially causing turbine disc fracture and 

release of high-energy debris, possibly 

resulting in damage to the aeroplane and/or 

injury to the occupants. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 67582, November 13, 2012). 

However, we changed paragraph (e) of 

this AD by removing the reporting 

requirement because that requirement is 

not necessary to correct the unsafe 

condition. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed (77 FR 67582, November 

13, 2012). 

Costs of Compliance 

Based on the service information, we 

estimate that this AD affects about 20 

engines of U.S. registry. We also 

estimate that it will take about 4 hours 

per product to comply with this AD. 

The average labor rate is $85 per hour. 

Required parts will cost about $1,848 

per engine. Based on these figures, we 

estimate the cost of the AD on U.S. 

operators to be $43,760. 

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 


wreier-aviles on DSK5TPTVN1PROD with RULES
17076 Federal Register / Vol. 78, No. 54 / Wednesday, March 20, 2013 / Rules and Regulations 

products identified in this rulemaking 

action. 

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); 

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 AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (phone: 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

Eurocopter France (Eurocopter) Model 

AS332C, L, and L1 helicopters to 

require a one-time inspection of the 

main rotor head (MRH) swash-plate 

upper bearing (bearing) for a nonsmooth point (friction point). This AD 

was prompted by a report of the 

premature deterioration of the MRH 

bearing of the rotating star installed on 

a Model AS332L1 helicopter. The 

actions of this AD are intended to detect 

deterioration of the MRH bearing and to 

prevent overloading the scissor links 

which drive the main rotor system, 

failure of the scissors links, and 

subsequent loss of control of the 

helicopter. 

DATES: This AD is effective April 24, 

2013.
