29694 Federal Register / Vol. 79, No. 100 / Friday, May 23, 2014 / Proposed Rules 

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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2013–12– 

01 that applies to all Rolls-Royce plc 

(RR) model RB211 Trent 768–60, 772– 

60, and 772B–60 turbofan engines. AD 

2013–12–01 requires a one-time 

ultrasonic inspection (UI) of lowpressure (LP) compressor blades with 

more than 2,500 flight cycles since new 

or last inspection. Since we issued AD 

2013–12–01, RR determined that 

repetitive UIs of the LP compressor 

blades are needed. This proposed AD 

would require initial and repetitive UIs 

of the affected LP compressor blades. 

We are proposing this AD to prevent LP 

compressor blade airfoil separations, 

damage to the engine, and damage to the 

airplane.

ADDRESSES section. Include ‘‘Docket No. 

FAA–2012–1327; Directorate Identifier 

2012–NE–47–AD’’ at the beginning of

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

On June 5, 2013, we issued AD 2013– 

12–01, Amendment 39–17478 (78 FR 

37703, June 24, 2013), (‘‘AD 2013–12– 

01’’), for all RR model RB211 Trent 768– 

60, 772–60, and 772B–60 turbofan 

engines. AD 2013–12–01 requires a onetime UI of LP compressor blades that 

have accumulated more than 2,500 

flight cycles since new. AD 2013–12–01 

resulted from LP compressor blade 

partial airfoil release events. We issued 

AD 2013–12–01 to prevent LP 

compressor blade airfoil separations, 

engine damage, and damage to the 

airplane. 

Actions Since Existing AD Was Issued 

Since we issued AD 2013–12–01, RR’s 

service experience and updated analysis 

has determined the need for repetitive 

inspections of the LP compressor 

blades. Also since we issued AD 2013– 

12–01, the European Aviation Safety 

Agency (EASA) has issued EASA AD 

2014–0031, dated February 4, 2014, 

which requires repetitive inspection of 

the LP compressor blades. 

Relevant Service Information 

We reviewed RR Alert NonModification Service Bulletin No. 

RB.211–72–AH465, dated July 15, 2013. 

The service information describes 

procedures for an initial UI followed by 

repetitive UIs of the affected LP 

compressor blades. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require an 

initial UI of LP compressor blades at 

3,600 cycles since new or before further 

flight. For LP compressor blades that 

exceed 2,200 cycles since last 

inspection (CSLI), the AD would require 

a UI before exceeding 3,000 CSLI or 

before further flight. This proposed AD 

would also require repetitive UIs of the 

affected LP compressor blades every 

2,400 CSLI thereafter. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 56 engines installed on 

airplanes of U.S. registry. We also 

estimate that it would take about 44 

hours per engine to comply with the 

intial inspection requirements in this 

proposed AD. The average labor rate is 

$85 per hour. Based on these figures, we 

estimate the cost of the proposed AD on 

U.S. operators to be $209,440. 

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 proposed 

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 have 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 that the 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.
