Airworthiness Directives; Rolls-Royce 

Deutschland Ltd & Co KG Turbofan 

Engines 

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) BR700–710A1–10 and BR700– 

710A2–20 turbofan engines, and certain 

BR700–710C4–11 model engines. This 

proposed AD was prompted by RRD 

performing an evaluation that 

determined that certain high-pressure 

turbine (HPT) stage 1 and stage 2 discs 

from a specific supplier may contain 

steel inclusions that may cause the discs 

to fail before they reach their current life 

limits. This proposed AD would require 

reducing the life limits for certain HPT 

stage 1 and stage 2 discs. We are 

proposing this AD to prevent failure of 

the HPT stage 1 and stage 2 discs, which 

could result in uncontained failure of 

the engine and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by January 15, 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 AD 2012– 

0166, dated August 30, 2012 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

The results of a recent quality review of 

high pressure turbine (HPT) stage 1 and stage 

2 discs identified potential for steel 

inclusions in some production scale parts. 

Further investigation concluded that all 

affected parts were manufactured by Udimet 

720I and melted by a certain supplier. 

Subsequent evaluation concluded that the 

affected parts life limitation values declared 

in the engine Time Limits Manual cannot be 

supported for discs with potential steel 

inclusion. 

This condition, if not corrected, could lead 

to an uncontained HPT disc failure, 

potentially resulting in damage to, and/or 

reduced control of the aeroplane. 

The FAA has further determined that 

the risk to the engine is increased by 

installing an HPT stage 1 disc and an 

HPT stage 2 disc from the affected 

population, on the same engine. 

Therefore the FAA is prohibiting the 

installation of an HPT stage 1 and HPT 

stage 2 disc from the affected population 

in the same engine. You may obtain 

further information by examining the 

MCAI in the AD docket. 

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 Germany, 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. This 

proposed AD would require reducing 

the life limits for certain HPT stage 1 

and HPT stage 2 discs that have a serial 

number listed in this proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 10 engines installed 

on airplanes of U.S. registry. Prorated 

parts life will cost about $210,000. 

Based on these figures, we estimate the 

cost of the proposed AD on U.S. 

operators to be $2,100,000. Our cost 

estimate is exclusive of possible 

warranty coverage. 

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, 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 AD: 

Rolls-Royce Deutschland Ltd & Co KG 

(Formerly Rolls-Royce Deutschland 

GmbH, formerly BMW Rolls-Royce 

GmbH): Docket No. FAA–2012–1055; 

Directorate Identifier 2012–NE–33–AD. 

(a) Comments Due Date 

We must receive comments by January 15, 

2013. 

(b) Affected Airworthiness Directives (ADs) 

None. 

(c) Applicability 

This AD applies to the following RollsRoyce Deutschland Ltd & Co KG (RRD) 

turbofan engines that have any of the highpressure turbine (HPT) stage 1 or stage 2 

discs with a serial number (S/N) listed in 

Table 1 to paragraph (c) of this AD, installed: 

(1) RRD BR700–710A1–10 and BR700– 

710A2–20 turbofan engines; and 

(2) BR700–710C4–11 model engines that 

have hardware configuration standard 

710C4–11 or 710C4–11/10 engraved on the

(d) Reason 

This AD was prompted by RRD performing 

an evaluation that determined that certain 

HPT stage 1 and stage 2 discs from a specific 

supplier may contain steel inclusions that 

may cause the discs to fail before they reach 

their current life limits. We are issuing this 

AD to prevent failure of the HPT stage 1 and 

stage 2 discs, which could result in 

uncontained failure of the engine and 

damage to the airplane. 

(e) Actions and Compliance 

Unless already done, remove from service 

the HPT stage 1 and stage 2 discs listed by 

S/N in Table 1 to paragraph (c) of this AD, 

at the following: 

(1) For BR700–710A1–10, BR700–710A2– 

20, and BR700–710C4–11 engine models 

(without RRD Mod 72–101466), remove the 

HPT stage 1 and stage 2 discs from service 

before accumulating 3,000 cycles-since-new 

(CSN). 

(2) For the BR700–710C4–11 engine model 

(with RRD Mod 72–101466), remove the HPT 

stage 1 and stage 2 discs from service before 

accumulating 2,300 CSN. 

(f) Installation Prohibition 

After the effective date of this AD, do not 

install an HPT stage 1 and an HPT stage 2 

disc, identified by S/N in Table 1 to 

paragraph (c) of this AD, in the same engine. 

(g) 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.
