ACTION: Final rule. AGENCY: We are adopting 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 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 SUMMARY: PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 10501 AD requires reducing the life limits for certain HPT stage 1 and stage 2 discs. 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. DATES: This AD becomes effective March 21, 2013. ADDRESSES: The Docket Operations office is located at Docket Management Facility, U.S. Department of Transportation, 1200 New Jersey Avenue SE., West Building Ground Floor, Room W12–140, Washington, DC 20590–0001.

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 16, 2012 (77 FR 68714). That NPRM proposed to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (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 discs from the affected population in the same engine. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We E:\FR\FM\14FER1.SGM 14FER1 10502 Federal Register / Vol. 78, No. 31 / Thursday, February 14, 2013 / Rules and Regulations received no comments on the NPRM (77 FR 68714, November 16, 2012). Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed (77 FR 68714, November 16, 2012). 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 We estimate that this AD will 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 this AD on U.S. operators to be $2,100,000. Our cost estimate is exclusive of possible warranty coverage. You may examine the AD docket on the Internet at https:// 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. Authority for This Rulemaking List of Subjects in 14 CFR Part 39 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.

SUPPLEMENTARY INFORMATION: mstockstill on DSK4VPTVN1PROD with RULES SUMMARY: A. Background 1. Statutory Authority On August 14, 2008, Congress enacted the CPSIA (Pub. L. 110–314), as VerDate Mar<15>2010 16:39 Feb 13, 2013 Jkt 229001 amended on August 12, 2011, by Public Law 112–28. Section 108 of the CPSIA, titled, ‘‘Prohibition on Sale of Certain Products Containing Specified Phthalates,’’ permanently prohibits the sale of any ‘‘children’s toy or child care article’’ containing more than 0.1 percent of three specified phthalates (di(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), and benzyl butyl phthalate (BBP)). Section 108 of the CPSIA also prohibits, on an interim basis, ‘‘toys that can be placed in a child’s mouth’’ or ‘‘child care article’’ containing more than 0.1 percent of three additional phthalates (diisononyl phthalate (DINP), diisodecyl phthalate (DIDP), and di-n-octyl phthalate (DnOP)). These prohibitions became effective on February 10, 2009. 15 U.S.C. 2057c(a), (b). The terms or phrases ‘‘children’s toy,’’ ‘‘toy that can be placed in a child’s mouth,’’ and ‘‘child care article,’’ are defined in section 108(g) of the CPSIA. A ‘‘children’s toy’’ is defined as a ‘‘consumer product designed or intended by the manufacturer for a child 12 years of age or younger for use by the child when the child plays.’’ A toy can be placed in a child’s mouth ‘‘if any part of the toy can actually be brought to the mouth and kept in the mouth by a child so that it can be sucked and chewed. If the children’s product can only be licked, it is not regarded as able to be placed in the mouth. If a toy or part of a toy in one dimension is smaller than 5 centimeters, it can be placed in a child’s mouth.’’ The term ‘‘child care article’’ means ‘‘a consumer product designed or intended by the manufacturer to facilitate sleep or the feeding of children age 3 years and younger, or to help such children with sucking or teething.’’ 15 U.S.C. 2057c(g). Section 108(d) of the CPSIA provides that the prohibitions for the specified phthalates shall not apply to any component part of a children’s toy or child care article that is not accessible to a child through normal and reasonably foreseeable use and abuse of such product, as determined by the Commission. That section further provides that a component part is not accessible, if such component part is not physically exposed, by reason of a sealed covering or casing, and does not become physically exposed through reasonably foreseeable use and abuse of the product. Reasonably foreseeable use and abuse includes swallowing, mouthing, breaking, or other children’s activities, and the aging of the product. 15 U.S.C. 2057c(d)(1). The CPSIA directs the Commission to: (A) Promulgate a rule providing guidance with respect to what product PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 10503 components, or classes of components, will be considered to be inaccessible; or (B) adopt the same guidance with respect to inaccessibility that was adopted by the Commission with regard to accessibility of lead under section 101(b)(2)(B) (15 U.S.C. 1278a(b)(2)(B)), with additional consideration, as appropriate, of whether such component can be placed in a child’s mouth. 15 U.S.C. 2057c(d)(3). Section 108 of the CPSIA also directed the Commission, not earlier than 180 days after the date of enactment of this Act [enacted Aug. 14, 2008], to appoint a Chronic Hazard Advisory Panel (CHAP), pursuant to the procedures of section 28 of the CPSA (15 U.S.C. 2077), to study the effects on children’s health of all phthalates and phthalate alternatives as used in children’s toys and child care articles. 15 U.S.C. 2057c(b)(2). The Commission appointed the CHAP on April 14, 2010, to study the effects on children’s health of all phthalates and phthalate alternatives, as used in children’s toys and child care articles. The CHAP currently is working on a report, including recommendations, to be sent to the Commission. Under section 108(d)(2) of the CPSIA, the Commission may revoke any or all exclusions granted based on the inaccessible component parts provision of section 108 of the CPSIA, at any time, and require that any or all component parts manufactured after such exclusion is revoked, comply with the prohibitions of phthalates, if the Commission finds, based on scientific evidence, that such compliance is necessary to protect the public health or safety. 15 U.S.C. 2057c(d)(2). 2. Notice of Proposed Guidance In the Federal Register notice of July 31, 2012 (77 FR 45297), the Commission published a proposed guidance on inaccessible phthalate-containing component parts. As stated in the preamble to the proposed guidance (77 FR 45299), the Commission proposed to adopt the lead guidance for determining inaccessible component parts for phthalates, with the exception of polyvinyl chloride (PVC or vinyl) or other plasticized materials covering mattresses and other sleep surfaces designed or intended by the manufacturer to facilitate sleep of children age 3 and younger. Both the lead guidance and proposed phthalate guidance specified that a children’s product, toy, or child care article that is completely enclosed or covered by fabric is considered inaccessible to a child, unless the product or part of the product in one dimension is smaller E:\FR\FM\14FER1.SGM 14FER1

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 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 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 AD 
requires reducing the life limits for certain HPT stage 1 and stage 2 
discs. 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.

DATES: This AD becomes effective March 21, 2013.

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 16, 2012 
(77 FR 68714). That NPRM proposed to correct an unsafe condition for 
the specified products. The Mandatory Continuing Airworthiness 
Information (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 discs 
from the affected population in the same engine. You may obtain further 
information by examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We

[[Page 10502]]

received no comments on the NPRM (77 FR 68714, November 16, 2012).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed (77 FR 68714, 
November 16, 2012).

Costs of Compliance

    We estimate that this AD will 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 this 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 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); 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 AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://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.

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2013-03-17 Rolls-Royce Deutschland Ltd & Co KG (Formerly Rolls-Royce 
Deutschland GmbH, formerly BMW Rolls-Royce GmbH): Amendment 39-
17351; Docket No. FAA-2012-1055; Directorate Identifier 2012-NE-33-
AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective March 21, 
2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the following Rolls-Royce Deutschland Ltd & 
Co KG (RRD) turbofan engines that have any of the high-pressure 
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 
engine data plate.

(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.
