Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule; request for comments. AGENCY: We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F.27 Mark 050 airplanes. This proposed AD would require performing a low frequency eddy current inspection for cracks of the lap joint of the rear fuselage, and repair if necessary. This AD was prompted by reports of cracking in the fuselage lap joint. We are issuing this AD to detect and correct exponential crack growth, which could lead to failure of the lap joint over a certain length and consequent in-flight decompression of the airplane. DATES: This AD becomes effective April 25, 2012. The Director of the Federal Register approved the incorporation by reference of the service information listed in the AD as of April 25, 2012.

SUPPLEMENTARY INFORMATION: 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 2011–0064, dated April 7, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: One operator reported a clearly visible crack in a fuselage lap joint, just forward of the ice protection plate in the forward fuselage. During a subsequent review of fatigue lives of lap joints in general, a critical location was found at a skin cut-out for a water service panel in the rear fuselage. Analysis by Fokker Services shows that at this specific location, due to the high local loads, cracks can occur from about 47,000 flight cycles (FC) in the inner skin. The outer skin will cover a crack in the inner skin and a crack will therefore not be visible. This condition, if not detected and corrected, can result in an exponential crack growth rate, possibly leading to failure of the lap joint over a certain length and consequent in-flight decompression of the aeroplane. For the reasons described above, this [EASA] AD requires a one-time lowfrequency eddy current inspection of the lap joint for cracks and, depending on findings, repair of the lap-joint. This [EASA] AD also requires sending an inspection report (even when no cracks are found) to the TC [type certificate] holder to confirm the selected inspection threshold for aeroplanes that have not yet accumulated 45,000 FC, as well as the inspection interval. The repetitive inspection task will be introduced in a future revision of the Fokker 50/60 Maintenance Review Board (MRB) Document. Repair of the lap joint constitutes terminating action for the repetitive inspections. In addition, the terminating action can also be applied before the initial inspection is required, thereby preventing the need for inspection altogether. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Fokker Services B.V. has issued Service Bulletin SBF50–53–061, dated January 13, 2011; and Service Bulletin E:\FR\FM\10APR1.SGM 10APR1 21396 Federal Register / Vol. 77, No. 69 / Tuesday, April 10, 2012 / Rules and Regulations SBF50–53–062, dated January 13, 2011. 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 AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future. tkelley on DSK3SPTVN1PROD with RULES FAA’s Determination of the Effective Date Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2012–0333; Directorate Identifier 2011–NM–085– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. 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 VerDate Mar<15>2010 16:37 Apr 09, 2012 Jkt 226001 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); 3. Will not affect intrastate aviation in Alaska; 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION: 

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 2011-0064, dated April 7, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    One operator reported a clearly visible crack in a fuselage lap 
joint, just forward of the ice protection plate in the forward 
fuselage. During a subsequent review of fatigue lives of lap joints 
in general, a critical location was found at a skin cut-out for a 
water service panel in the rear fuselage. Analysis by Fokker 
Services shows that at this specific location, due to the high local 
loads, cracks can occur from about 47,000 flight cycles (FC) in the 
inner skin. The outer skin will cover a crack in the inner skin and 
a crack will therefore not be visible.
    This condition, if not detected and corrected, can result in an 
exponential crack growth rate, possibly leading to failure of the 
lap joint over a certain length and consequent in-flight 
decompression of the aeroplane.
    For the reasons described above, this [EASA] AD requires a one-
time low-frequency eddy current inspection of the lap joint for 
cracks and, depending on findings, repair of the lap-joint. This 
[EASA] AD also requires sending an inspection report (even when no 
cracks are found) to the TC [type certificate] holder to confirm the 
selected inspection threshold for aeroplanes that have not yet 
accumulated 45,000 FC, as well as the inspection interval. The 
repetitive inspection task will be introduced in a future revision 
of the Fokker 50/60 Maintenance Review Board (MRB) Document.
    Repair of the lap joint constitutes terminating action for the 
repetitive inspections. In addition, the terminating action can also 
be applied before the initial inspection is required, thereby 
preventing the need for inspection altogether.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Fokker Services B.V. has issued Service Bulletin SBF50-53-061, 
dated January 13, 2011; and Service Bulletin

[[Page 21396]]

SBF50-53-062, dated January 13, 2011. 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 AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2012-0333; Directorate 
Identifier 2011-NM-085-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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

crack growth, which could lead to failure of the lap joint over a 
certain length and consequent in-flight decompression of the 
airplane.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Inspection

    Within the applicable times specified in paragraphs (g)(1), 
(g)(2), or (g)(3) of this AD: Do a low frequency eddy current (LFEC) 
inspection for cracks of the lap joint of the rear fuselage, in 
accordance with the Accomplishment Instructions of Fokker Service 
Bulletin SBF50-53-061, dated January 13, 2011.
    (1) For airplanes that have accumulated 47,000 total flight 
cycles or more as of the effective date of this AD: Within 3 months 
after the effective date of this AD.
    (2) For airplanes that have accumulated more than 46,000 total 
flight cycles but less than 47,000 total flight cycles as of the 
effective date of this AD: Within 6 months after the effective date 
of this AD.
    (3) For airplanes that have accumulated more than 45,000 total 
flight cycles but less than or equal to 46,000 total flight cycles 
as of the effective date of this AD: Within 12 months after the 
effective date of this AD.

    If any crack is found during the LFEC inspection required by 
paragraph (g) of this AD, before further flight, repair the lap 
joint in accordance with the Accomplishment Instructions of Fokker 
Service Bulletin SBF50-53-062, dated January 13, 2011.

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR

FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: A federal agency may not conduct or 
sponsor, and a person is not required to respond to, nor shall a 
person be subject to a penalty for failure to comply with a 
collection of information subject to the requirements of the 
Paperwork Reduction Act unless that collection of information 
displays a current valid OMB Control Number. The OMB Control Number 
for this information collection is 2120-0056. Public reporting for 
this collection of information is estimated to be approximately 5 
minutes per response, including the time for reviewing instructions,
