Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
Rolls-Royce Deutschland Ltd & Co KG (RRD) (formerly Rolls-Royce 
Deutschland GmbH, formerly BMW Rolls-Royce GmbH) model BR700-715A1-30, 
BR700-715B1-30, and BR700-715C1-30 turbofan engines. This AD requires a 
onetime inspection of the Independent Overspeed Protection (IOP) unit, 
part number (P/N) 112E9321G2, for 19 specific serial numbers (SNs), and 
removal from service of those units. This AD results from a report that 
incorrect capacitors were installed in 19 IOP units. The incorrect 
capacitor in the IOP unit can lead to an inadvertent IOP command 
resulting in an in-flight engine shutdown. We are issuing this AD to 
prevent inadvertent dual-engine in-flight shutdown.

DATES: Effective August 26, 2005.
    We must receive any comments on this AD by October 11, 2005.

SUPPLEMENTARY INFORMATION: The Luftfahrt-Bundesamt (LBA), which is the 
airworthiness authority for Germany, recently notified us that an 
unsafe condition may exist on RRD model BR700-715A1-30, BR700-715B1-30, 
and BR700-715C1-30 turbofan engines. The LBA advises that the supplier 
of the IOP unit informed RRD that incorrect capacitors were installed 
in 19 IOP units, P/N 112E9321G2. The incorrect capacitor in the IOP 
unit can lead to an inadvertent IOP command and an in-flight engine 
shutdown. If both engines of an airplane have an affected IOP unit, 
inadvertent dual-engine in-flight shutdown could occur. The LBA issued 
airworthiness directive D-2005-221, dated June 17, 2005, in order to 
ensure the airworthiness of these engines in Germany.

Bilateral Airworthiness Agreement

    These model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 
turbofan engines are manufactured in Germany and are type certificated 
for operation in the United States under the provisions of section 
21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the 
applicable bilateral airworthiness agreement. Under this bilateral 
airworthiness agreement, the LBA kept the FAA informed of the situation 
described above. We have examined the findings of the LBA, reviewed all 
available information, and determined that AD action is necessary for 
products of this type design that are certificated for operation in the 
United States.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-
30 turbofan engines of the same type design. We are issuing this AD to 
prevent inadvertent dual-engine in-flight shutdown. This AD requires:
    <bullet> Within 10 flight cycles after the effective date of the 
AD, inspection of each engine's IOP unit, part number 112E9321G2, for 
the affected serial numbers; and
    <bullet> If neither engine has an IOP unit listed in Table 1 of 
this AD, no further action is required; and
    <bullet> If both engines have IOP units listed in Table 1 of this 
AD installed, remove at least one of the IOP units from service before 
further flight.
    <bullet> If one engine has an IOP unit listed in Table 1 of this 
AD, remove the listed IOP from service no later than August 31, 2005.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we have found that notice and opportunity for 
public comment before issuing this AD are impracticable, and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment; however, we invite you to send us any written relevant data, 
views, or arguments regarding this AD. Send your comments to an address 
listed under ADDRESSES. Include ``AD Docket No. FAA-2005-22070; 
Directorate Identifier 2005-NE-23-AD'' in the subject line of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify it.
    We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact with FAA 
personnel concerning this AD. Using the search function of the Docket 
Management System (DMS) Web site, anyone can find and read the comments 
in any of our dockets, including the name of the individual who sent 
the comment (or signed the comment on

[[Page 46753]]

behalf of an association, business, labor union, etc.). You may review 
the DOT's complete Privacy Act Statement in the Federal Register 
published on April 11, 2000 (65 FR 19477-78) or you may visit http://dms.dot.gov.

Examining the AD Docket

    You may examine the docket that contains the AD, any comments 
received, and any final disposition in person at the DMS Docket Office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Office (telephone (800) 647-5227) is located on 
the plaza level of the Department of Transportation Nassif Building at 
the street address stated in ADDRESSES. Comments will be available in 
the AD docket shortly after the Docket Office receives them.

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 have 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 that the 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 summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary by 
sending a request to us at the address listed under ADDRESSES.
