AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

There have been several findings of 

cracking at the firtrees of LP Turbine discs. 

Fatigue crack initiation and subsequent crack 

propagation at the firtree may result in 

multiple LP Turbine blade release. The latter 

may potentially be beyond the containment 

capabilities of the engine casings. Thus, 

cracking at the firtrees of LP Turbine discs 

constitutes a potentially unsafe condition. 

We are proposing this AD to detect 

cracks in the low-pressure turbine stage 

1, 2, and 3 discs, which could result in 

an uncontained release of LP turbine 

blades and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by November 19, 

2010.

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 2009–0244, 

dated November 9, 2009 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

There have been several findings of 

cracking at the firtrees of LP Turbine discs. 

Fatigue crack initiation and subsequent crack 

propagation at the firtree may result in 

multiple LP Turbine blade release. The latter 

may potentially be beyond the containment 

capabilities of the engine casings. Thus, 

cracking at the firtrees of LP Turbine discs 

constitutes a potentially unsafe condition. 

Therefore this Airworthiness Directive 

requires a change to the inspection intervals 

of LP Turbine Discs. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Rolls-Royce plc has issued Alert 

Service Bulletin (ASB) RB.211–72– 

AG272, dated August 5, 2009. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of the United 

Kingdom, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the United 

Kingdom, they have 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 products of the 

same type design. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 90 products of U.S. registry. 

We also estimate that it would take 

about 30 work-hours per product to 

comply with this proposed AD. The 

average labor rate is $85 per work-hour. 

No parts are required. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$229,500. 

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); and 

3. 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, 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 AD: 

Rolls-Royce plc: Docket No. FAA–2010– 

0994; Directorate Identifier 2009–NE– 

39–AD. 

Comments Due Date 

(a) We must receive comments by 

November 19, 2010. 

Affected Airworthiness Directives (ADs) 

(b) None. 

Applicability 

(c) This AD applies to Rolls-Royce plc 

RB211–535E4–37, –535E4–B–37, –535E4–B– 

75, and –535E4–C–37 turbofan engines. 

These engines are installed on, but not 

limited to, Boeing 757–200 series, –200PF 

series, –200CB series, and –300 series 

airplanes and Tupolev Tu204 series 

airplanes. 

Reason 

(d) This AD results from several findings 

of cracking at the firtrees of low-pressure (LP) 

turbine discs. Fatigue crack initiation and 

subsequent crack propagation at the firtree 

may result in multiple LP turbine blade 

release. We are issuing this AD to detect 

cracks in the LP turbine stage 1, 2, and 3 

discs, which could result in an uncontained 

release of LP turbine blades and damage to 

the airplane. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

Initial Inspection Requirements 

(1) At the next engine shop visit after the 

effective date of this AD, perform a visual 

and a fluorescent penetrant inspection (FPI) 

of the LP turbine stage 1, 2, and 3 disc. You 

can find guidance on the visual and FPI in 

Section 3, Accomplishment Instructions, of 


hsrobinson on DSK69SOYB1PROD with PROPOSALS-1
Federal Register / Vol. 75, No. 192 / Tuesday, October 5, 2010 / Proposed Rules 61363 

Rolls-Royce Alert Service Bulletin (ASB) No. 

RB.211 72–AG272. 

Repeat Inspection Requirements 

(2) At each engine shop visit after 

accumulating 1,500 cycles since the last 

inspection of the LP turbine stage 1, 2 and 

3 discs, repeat the inspections specified in 

paragraph (e)(1) of this AD. 

Remove Cracked Discs 

(3) If you find cracks, remove the disc from 

service. 

Definitions 

(f) For the purpose of this AD, an ‘‘engine 

shop visit’’ is the induction of an engine into 

the shop for maintenance involving the 

separation of pairs of major mating engine 

flanges, except that the separation of engine 

flanges solely for the purposes of 

transportation without subsequent engine 

maintenance does not constitute an engine 

shop visit. 

FAA AD Differences 

(g) This AD differs from the Mandatory 

Continuing Airworthiness Information 

(MCAI) and or service information as follows 

in that while the MCAI compliance requires 

action at a current shop visit, this AD 

requires compliance at the next shop visit 

after the effective date of this AD. 

Other FAA AD Provisions 

(h) Alternative Methods of Compliance 

(AMOCs): The Manager, Engine Certification 

Office, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19.

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Cracking has been found on the inner wall 

between intermediate dilution chutes on a 

total of five front combustion liners of the 

standard corresponding to Rolls-Royce 

RB211 Service Bulletin No. 72–D133. The 

lives of two of these liners were confirmed 

to be below the currently valid borescope 

inspection interval. Ultimately, crack 

propagation could result in hot gas breakout 

with potential of downstream component 

distress and multiple turbine blade release 

beyond containment capabilities of the 

engine casings. Thus, cracking of this nature 

constitutes a potentially unsafe condition. 

Since Rolls-Royce Service Bulletin No. 72– 

E902 introduces further developments of 

Rolls-Royce RB211 Service Bulletin No. 72– 

D133, engines incorporating Rolls-Royce 

RB211 Service Bulletin No. 72–E902 are also 

considered to be potentially affected and are 

therefore included in the applicability of this 

AD. 

We are proposing this AD to detect 

cracks in the front combustion liner, 

which could result in hot section 

distress, uncontained multiple blade 

release and possible damage to the 

aircraft.

this proposed AD by November 19,
