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] RIN 2120–AA64 Airworthiness Directives; Fokker Services B.V. Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: We are revising an earlier proposed airworthiness directive (AD) for all Fokker Services B.V. Model F.27 Mark 050 airplanes, and Model F.28 Mark 0070 and 0100 airplanes. That NPRM proposed to require inspecting and, if necessary, adjusting, the torque values of nuts on circuit breakers, contactors, and terminal blocks of the electrical power center (EPC) and battery relay panel. This proposed AD would also require inspecting to determine if certain parts are installed, and installing the parts if necessary.

Discussion We proposed to amend 14 CFR part 39 with an earlier NPRM for the specified products, which was published in the Federal Register on March 21, 2012 (77 FR 16486). That earlier NPRM proposed to require actions intended to address the unsafe condition for the products listed above. Since that NPRM (77 FR 16486, March 21, 2012) was issued, we have determined that an additional terminal block used in some Model F.28 Mark 0100 airplanes needs to be included in the required actions proposed in the earlier NPRM. European Aviation Safety Agency (EASA) has issued Airworthiness Directive 2012–0050, dated March 27, 2012 (referred to after this as ‘‘the MCAI’’), to add that terminal block to their required actions. The MCAI states: 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 proposed AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. FOR FURTHER INFORMATION CONTACT: Tom Rodriguez, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 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 PO 00000 Frm 00019 Fmt 4702 Sfmt 4702 E:\FR\FM\05FEP1.SGM 05FEP1 Federal Register / Vol. 78, No. 24 / Tuesday, February 5, 2013 / Proposed Rules 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 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. Relevant Service Information Fokker Services B.V. has issued Service Bulletin SBF100–24–043, Revision 1, dated December 15, 2011 (for Model F.28 Mark 0070 and 0100 airplanes). The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. mstockstill on DSK4VPTVN1PROD with PROPOSALS Comments We gave the public the opportunity to comment on the earlier NPRM (77 FR 16486, March 21, 2012). We received no comments on that NPRM or on the determination of the cost to the public. FAA’s Determination and Requirements of This Proposed 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 proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Certain changes described above expand the scope of the earlier NPRM (77 FR 16486, March 21, 2012). As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for VerDate Mar<15>2010 16:28 Feb 04, 2013 Jkt 229001 the public to comment on this proposed AD. Difference Between the Proposed AD and the MCAI The MCAI specifies credit for actions done according to Fokker Service Bulletin SBF100–24–043, dated February 10, 2011, which does not include inspecting the additional terminal block part number. This proposed AD does not specify such credit because we determined that inspecting for the additional terminal block more properly meets the intent of this proposed AD. This difference has been coordinated with EASA. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 4 products of U.S. registry. We also estimate that it would take about 5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on 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 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 PO 00000 Frm 00020 Fmt 4702 Sfmt 4702 8059 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); 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 proposed AD and placed it in the AD docket.

Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for all Fokker Services B.V. Model F.27 Mark 050 airplanes, and 
Model F.28 Mark 0070 and 0100 airplanes. That NPRM proposed to require 
inspecting and, if necessary, adjusting, the torque values of nuts on 
circuit breakers, contactors, and terminal blocks of the electrical 
power center (EPC) and battery relay panel. This proposed AD would also 
require inspecting to determine if certain parts are installed, and 
installing the parts if necessary. This action revises that NPRM by 
adding a previously omitted terminal block to the required actions. We 
are proposing 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. Since these actions impose an additional burden over that 
proposed in the NPRM, we are reopening the comment period to allow the 
public the chance to comment on these proposed changes.

DATES: We must receive comments on this proposed AD by March 22, 2013.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    We proposed to amend 14 CFR part 39 with an earlier NPRM for the 
specified products, which was published in the Federal Register on 
March 21, 2012 (77 FR 16486). That earlier NPRM proposed to require 
actions intended to address the unsafe condition for the products 
listed above.
    Since that NPRM (77 FR 16486, March 21, 2012) was issued, we have 
determined that an additional terminal block used in some Model F.28 
Mark 0100 airplanes needs to be included in the required actions 
proposed in the earlier NPRM. European Aviation Safety Agency (EASA) 
has issued Airworthiness Directive 2012-0050, dated March 27, 2012 
(referred to after this as ``the MCAI''), to add that terminal block to 
their required actions. 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

[[Page 8059]]

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.

Relevant Service Information

    Fokker Services B.V. has issued Service Bulletin SBF100-24-043, 
Revision 1, dated December 15, 2011 (for Model F.28 Mark 0070 and 0100 
airplanes). The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

Comments

    We gave the public the opportunity to comment on the earlier NPRM 
(77 FR 16486, March 21, 2012). We received no comments on that NPRM or 
on the determination of the cost to the public.

FAA's Determination and Requirements of This Proposed 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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    Certain changes described above expand the scope of the earlier 
NPRM (77 FR 16486, March 21, 2012). As a result, we have determined 
that it is necessary to reopen the comment period to provide additional 
opportunity for the public to comment on this proposed AD.

Difference Between the Proposed AD and the MCAI

    The MCAI specifies credit for actions done according to Fokker 
Service Bulletin SBF100-24-043, dated February 10, 2011, which does not 
include inspecting the additional terminal block part number. This 
proposed AD does not specify such credit because we determined that 
inspecting for the additional terminal block more properly meets the 
intent of this proposed AD. This difference has been coordinated with 
EASA.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 4 products of U.S. registry. We also estimate that 
it would take about 5 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on 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 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);
    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 proposed AD and placed it in the AD docket.
