[FR Doc. 2013–22170 Filed 9–12–13; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2012–0270; Directorate Identifier 2011–NM–113–AD; Amendment 39–17570; AD 2013–17–06] RIN 2120–AA64 Airworthiness Directives; Fokker Services B.V. Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.27 Mark 050 airplanes, and Model F.28 Mark 0070 and 0100 airplanes. This AD was prompted by reports of loose nuts on contactors in the electrical power center (EPC), and in some cases, burned contactors. This AD requires inspecting and, if necessary, adjusting, the torque values of nuts on circuit breakers, contactors, and terminal blocks of the EPC and battery relay panel. This AD also requires inspecting to determine if certain parts are installed, and installing the parts if necessary. We are issuing this AD to detect and correct loose nuts, which could result in arcing and potentially an onboard fire, possibly resulting in damage to the airplane and injury to occupants or maintenance personnel. SUMMARY: This AD becomes effective October 18, 2013. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 18, 2013.

SUPPLEMENTARY INFORMATION: Discussion emcdonald on DSK67QTVN1PROD with RULES We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. The SNPRM published in the Federal Register on February 5, 2013 (78 FR 8058). We preceded the SNPRM with a notice of proposed rulemaking (NPRM), which published in the Federal Register on March 21, 2012 (77 FR 16486). The NPRM and the SNPRM both proposed to correct an unsafe condition for the specified products. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, issued EASA Airworthiness Directive 2012–0050, dated March 27, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: In December 1989, Fokker issued Service Bulletin (SB) SBF50–24–A013 and SBF100– 24–A011 (both Alert Bulletins) to instruct operators to inspect and adjust several torque values of bus bars and contactors in the EPC. The Civil Aviation Authority of The Netherlands (CAA–NL, formerly RLD) issued AD (BLA) 89–159 and BLA 89–157 respectively (both now at issue 2), to require operators of the affected aeroplanes to comply with the instructions of these SB’s. Since those [Dutch] ADs were issued, several operators reported finding loose nuts on contactors in the EPC of Fokker 50/60 aeroplanes in post-SBF50–24–A013 configuration and on Fokker 70/100 aeroplanes in post-SBF100–24–A011 configuration. In some cases, the findings included damaged (burned) contactors. This condition, if not detected and corrected, could lead to arcing and, in combination with other factors, to an onboard fire, possibly resulting in damage to the aeroplane and injury to occupants or maintenance personnel. EASA issued AD 2011–0083 [referenced in the earlier FAA NPRM (77 FR 16486, March 21, 2012)] to address this unsafe condition. After that [EASA] AD was issued, it was noticed that terminal block TB4906A, used in some Fokker 100 aeroplanes, was missing from the list of affected terminal blocks, as specified in Fokker SBF100–24–043. To correct this oversight, Fokker Services issued VerDate Mar<15>2010 17:44 Sep 12, 2013 Jkt 229001 Revision 1 of SBF100–24–043, adding terminal block TB4906A. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2011–0083, which is superseded, and for F28 Mark 0100 aeroplanes, adds required action for the missing terminal block TB4906A by making reference to SBF100– 24–043 Revision 1. The required actions include doing a general visual inspection to determine if either the lock washer, flat washer and nut, or locking nut and flat washer are installed; installing a new lock washer or self-locking nut, if necessary; and applying torque inspection lacquer. 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 received no comments on the SNPRM (78 FR 8058, February 5, 2013) or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed—except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the SNPRM (78 FR 8058, February 5, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the SNPRM (78 FR 8058, February 5, 2013). Costs of Compliance We estimate that this AD will affect about 4 products of U.S. registry. We also estimate that it will take about 5 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $1,700, or $425 per product. In addition, we estimate that any necessary follow-on actions would take about 4 work-hours and require parts costing $25, for a cost of $365 per product. We have no way of determining the number of products that may need these actions. 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. PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 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 that 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. 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 MCAI, the regulatory evaluation, any comments received, and other information.

Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Fokker Services B.V. Model F.27 Mark 050 airplanes, and Model F.28 Mark 
0070 and 0100 airplanes. This AD was prompted by reports of loose nuts 
on contactors in the electrical power center (EPC), and in some cases, 
burned contactors. This AD requires inspecting and, if necessary, 
adjusting, the torque values of nuts on circuit breakers, contactors, 
and terminal blocks of the EPC and battery relay panel. This AD also 
requires inspecting to determine if certain parts are installed, and 
installing the parts if necessary. We are issuing this AD to detect and 
correct loose nuts, which could result in arcing and potentially an 
onboard fire, possibly resulting in damage to the airplane and injury 
to occupants or maintenance personnel.

DATES: This AD becomes effective October 18, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 18, 
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to include an AD that would apply to the specified 
products. The SNPRM published in the Federal Register on February 5, 
2013 (78 FR 8058). We preceded the SNPRM with a notice of proposed 
rulemaking (NPRM), which published in the Federal Register on March 21, 
2012 (77 FR 16486). The NPRM and the SNPRM both proposed to correct an 
unsafe condition for the specified products.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, issued EASA 
Airworthiness Directive 2012-0050, dated March 27, 2012 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    In December 1989, Fokker issued Service Bulletin (SB) SBF50-24-
A013 and SBF100-24-A011 (both Alert Bulletins) to instruct operators 
to inspect and adjust several torque values of bus bars and 
contactors in the EPC. The Civil Aviation Authority of The 
Netherlands (CAA-NL, formerly RLD) issued AD (BLA) 89-159 and BLA 
89-157 respectively (both now at issue 2), to require operators of 
the affected aeroplanes to comply with the instructions of these 
SB's.
    Since those [Dutch] ADs were issued, several operators reported 
finding loose nuts on contactors in the EPC of Fokker 50/60 
aeroplanes in post-SBF50-24-A013 configuration and on Fokker 70/100 
aeroplanes in post-SBF100-24-A011 configuration. In some cases, the 
findings included damaged (burned) contactors.
    This condition, if not detected and corrected, could lead to 
arcing and, in combination with other factors, to an on-board fire, 
possibly resulting in damage to the aeroplane and injury to 
occupants or maintenance personnel. EASA issued AD 2011-0083 
[referenced in the earlier FAA NPRM (77 FR 16486, March 21, 2012)] 
to address this unsafe condition.
    After that [EASA] AD was issued, it was noticed that terminal 
block TB4906A, used in some Fokker 100 aeroplanes, was missing from 
the list of affected terminal blocks, as specified in Fokker SBF100-
24-043. To correct this oversight, Fokker Services issued Revision 1 
of SBF100-24-043, adding terminal block TB4906A.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2011-0083, which is superseded, and for F28 
Mark 0100 aeroplanes, adds required action for the missing terminal 
block TB4906A by making reference to SBF100-24-043 Revision 1.

    The required actions include doing a general visual inspection to 
determine if either the lock washer, flat washer and nut, or locking 
nut and flat washer are installed; installing a new lock washer or 
self-locking nut, if necessary; and applying torque inspection lacquer. 
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 received no comments on the SNPRM (78 FR 8058, February 5, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed--except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM (78 FR 8058, February 5, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM (78 FR 8058, February 5, 2013).

Costs of Compliance

    We estimate that this AD will affect about 4 products of U.S. 
registry. We also estimate that it will take about 5 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this AD to the U.S. operators to be $1,700, or $425 per 
product.
    In addition, we estimate that any necessary follow-on actions would 
take about 4 work-hours and require parts costing $25, for a cost of 
$365 per product. We have no way of determining the number of products 
that may need these actions.

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 that 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.
