[FR Doc. 2015–23420 Filed 9–17–15; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2015–3633; Directorate Identifier 2014–NM–097–AD] RIN 2120–AA64 Airworthiness Directives; Fokker Services B.V. Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes. This proposed AD was prompted by a design review conducted by Fokker Services B.V. that indicated no controlled bonding provisions were present on many critical locations outside the fuel tank or connected to the fuel tank wall. This proposed AD would require installing the additional bonding provisions, and revising the maintenance or inspection program, as applicable, by incorporating fuel airworthiness limitation items and critical design configuration control limitations. We are proposing this AD to prevent an ignition source in the fuel tank vapor space, which could result in a fuel tank explosion and consequent loss of the airplane. DATES: We must receive comments on this proposed AD by November 2, 2015. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 56413 for the Member States of the European Union, has issued EASA Airworthiness Directive 2014–0100, dated April 30, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Fokker Services B.V. Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes. The MCAI states: Prompted by an accident * * *, the FAA published Special Federal Aviation Regulation (SFAR) 88 [(66 FR 23086, May 7, 2001)], and the Joint Aviation Authorities (JAA) published Interim Policy INT/POL/25/ 12. The review conducted by Fokker Services on the Fokker 27 design in response to these regulations revealed that no controlled bonding provisions are present on a number of critical locations outside the fuel tanks. This condition, if not corrected, could create an ignition source in the fuel tank vapour space, possibly resulting in a fuel tank explosion and consequent loss of the aeroplane. To address this potential unsafe condition, Fokker Services developed a set of bonding modifications, introduced with [a service bulletin] * * *, that do[es] not require opening of the fuel tank access panels. More information on this subject can be found in Fokker Services All Operators Message AOF27.043#03. For the reasons described above, this [EASA] AD requires installation of additional bonding provisions that do not require opening of the fuel tank access panels. Required actions also include revising the maintenance or inspection program, as applicable, by incorporating fuel airworthiness limitation items and critical design configuration control limitations. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2015– 3633. The FAA has examined the underlying safety issues involved in fuel tank explosions on several large transport airplanes, including the adequacy of existing regulations, the service history of airplanes subject to those regulations, and existing maintenance practices for fuel tank systems. As a result of those findings, we issued a regulation titled ‘‘Transport Airplane Fuel Tank System Design Review, Flammability Reduction and Maintenance and Inspection Requirements’’ (66 FR 23086, May 7, 2001). In addition to new airworthiness standards for transport airplanes and new maintenance requirements, this rule included Special Federal Aviation Regulation No. 88 (‘‘SFAR 88,’’ Amendment 21–78, and subsequent Amendments 21–82 and 21–83). Among other actions, SFAR 88 (66 FR 23086, May 7, 2001) requires certain E:\FR\FM\18SEP1.SGM 18SEP1 56414 Federal Register / Vol. 80, No. 181 / Friday, September 18, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS type design (i.e., type certificate (TC) and supplemental type certificate (STC)) holders to substantiate that their fuel tank systems can prevent ignition sources in the fuel tanks. This requirement applies to type design holders for large turbine-powered transport airplanes and for subsequent modifications to those airplanes. It requires them to perform design reviews and to develop design changes and maintenance procedures if their designs do not meet the new fuel tank safety standards. As explained in the preamble to the rule, we intended to adopt airworthiness directives to mandate any changes found necessary to address unsafe conditions identified as a result of these reviews. In evaluating these design reviews, we have established four criteria intended to define the unsafe conditions associated with fuel tank systems that require corrective actions. The percentage of operating time during which fuel tanks are exposed to flammable conditions is one of these criteria. The other three criteria address the failure types under evaluation: Single failures, single failures in combination with a latent condition(s), and in-service failure experience. For all four criteria, the evaluations included consideration of previous actions taken that may mitigate the need for further action. The Joint Aviation Authorities (JAA) has issued a regulation that is similar to SFAR 88 (66 FR 23086, May 7, 2001). (The JAA is an associated body of the European Civil Aviation Conference (ECAC) representing the civil aviation regulatory authorities of a number of European States who have agreed to cooperate in developing and implementing common safety regulatory standards and procedures.) Under this regulation, the JAA stated that all members of the ECAC that hold type certificates for transport category airplanes are required to conduct a design review against explosion risks. We have determined that the actions identified in this AD are necessary to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. Related Service Information Under 1 CFR Part 51 Fokker Services B.V. has issued F27 Proforma Service Bulletin SBF27–28– 072, Revision 1, dated March 6, 2014, including Fokker F27 Service Bulletin Appendix SBF27–28–072/APP01, including List of Drawings/Part Lists, dated July 17, 2014; and Fokker Manual VerDate Sep<11>2014 17:14 Sep 17, 2015 Jkt 235001 Change Notification—Maintenance Documentation (MCNM) F27–027 dated September 9, 2014. The service information describes procedures for installing additional bonding provisions. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM. 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 this same type design. This proposed AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, an operator might not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) in accordance with the provisions of paragraph (j) of this proposed AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane. Costs of Compliance We estimate that this proposed AD affects 15 airplanes of U.S. registry. We also estimate that it would take about 8 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 this proposed AD on U.S. operators to be $10,200, or $680 per product. 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: PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

by Fokker Services B.V. that indicated no controlled bonding provisions 
were present on many critical locations outside the fuel tank or 
connected to the fuel tank wall. This proposed AD would require 
installing the additional bonding provisions, and revising the 
maintenance or inspection program, as applicable, by incorporating fuel 
airworthiness limitation items and critical design configuration 
control limitations. We are proposing this AD to prevent an ignition 
source in the fuel tank vapor space, which could result in a fuel tank 
explosion and consequent loss of the airplane.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0100, dated April 30, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Fokker Services 
B.V. Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes. The 
MCAI states:

    Prompted by an accident * * *, the FAA published Special Federal 
Aviation Regulation (SFAR) 88 [(66 FR 23086, May 7, 2001)], and the 
Joint Aviation Authorities (JAA) published Interim Policy INT/POL/
25/12.
    The review conducted by Fokker Services on the Fokker 27 design 
in response to these regulations revealed that no controlled bonding 
provisions are present on a number of critical locations outside the 
fuel tanks.
    This condition, if not corrected, could create an ignition 
source in the fuel tank vapour space, possibly resulting in a fuel 
tank explosion and consequent loss of the aeroplane.
    To address this potential unsafe condition, Fokker Services 
developed a set of bonding modifications, introduced with [a service 
bulletin] * * *, that do[es] not require opening of the fuel tank 
access panels.
    More information on this subject can be found in Fokker Services 
All Operators Message AOF27.043#03.
    For the reasons described above, this [EASA] AD requires 
installation of additional bonding provisions that do not require 
opening of the fuel tank access panels.

    Required actions also include revising the maintenance or 
inspection program, as applicable, by incorporating fuel airworthiness 
limitation items and critical design configuration control limitations. 
You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
3633.
    The FAA has examined the underlying safety issues involved in fuel 
tank explosions on several large transport airplanes, including the 
adequacy of existing regulations, the service history of airplanes 
subject to those regulations, and existing maintenance practices for 
fuel tank systems. As a result of those findings, we issued a 
regulation titled ``Transport Airplane Fuel Tank System Design Review, 
Flammability Reduction and Maintenance and Inspection Requirements'' 
(66 FR 23086, May 7, 2001). In addition to new airworthiness standards 
for transport airplanes and new maintenance requirements, this rule 
included Special Federal Aviation Regulation No. 88 (``SFAR 88,'' 
Amendment 21-78, and subsequent Amendments 21-82 and 21-83).
    Among other actions, SFAR 88 (66 FR 23086, May 7, 2001) requires 
certain

[[Page 56414]]

type design (i.e., type certificate (TC) and supplemental type 
certificate (STC)) holders to substantiate that their fuel tank systems 
can prevent ignition sources in the fuel tanks. This requirement 
applies to type design holders for large turbine-powered transport 
airplanes and for subsequent modifications to those airplanes. It 
requires them to perform design reviews and to develop design changes 
and maintenance procedures if their designs do not meet the new fuel 
tank safety standards. As explained in the preamble to the rule, we 
intended to adopt airworthiness directives to mandate any changes found 
necessary to address unsafe conditions identified as a result of these 
reviews.
    In evaluating these design reviews, we have established four 
criteria intended to define the unsafe conditions associated with fuel 
tank systems that require corrective actions. The percentage of 
operating time during which fuel tanks are exposed to flammable 
conditions is one of these criteria. The other three criteria address 
the failure types under evaluation: Single failures, single failures in 
combination with a latent condition(s), and in-service failure 
experience. For all four criteria, the evaluations included 
consideration of previous actions taken that may mitigate the need for 
further action.
    The Joint Aviation Authorities (JAA) has issued a regulation that 
is similar to SFAR 88 (66 FR 23086, May 7, 2001). (The JAA is an 
associated body of the European Civil Aviation Conference (ECAC) 
representing the civil aviation regulatory authorities of a number of 
European States who have agreed to co-operate in developing and 
implementing common safety regulatory standards and procedures.) Under 
this regulation, the JAA stated that all members of the ECAC that hold 
type certificates for transport category airplanes are required to 
conduct a design review against explosion risks.
    We have determined that the actions identified in this AD are 
necessary to reduce the potential of ignition sources inside fuel 
tanks, which, in combination with flammable fuel vapors, could result 
in fuel tank explosions and consequent loss of the airplane.

Related Service Information Under 1 CFR Part 51

    Fokker Services B.V. has issued F27 Proforma Service Bulletin 
SBF27-28-072, Revision 1, dated March 6, 2014, including Fokker F27 
Service Bulletin Appendix SBF27-28-072/APP01, including List of 
Drawings/Part Lists, dated July 17, 2014; and Fokker Manual Change 
Notification--Maintenance Documentation (MCNM) F27-027 dated September 
9, 2014. The service information describes procedures for installing 
additional bonding provisions. This service information is reasonably 
available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section of this NPRM.

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 this same 
type design.
    This proposed AD requires revisions to certain operator maintenance 
documents to include new inspections. Compliance with these inspections 
is required by section 91.403(c) of the Federal Aviation Regulations 
(14 CFR 91.403(c)). For airplanes that have been previously modified, 
altered, or repaired in the areas addressed by these inspections, an 
operator might not be able to accomplish the inspections described in 
the revisions. In this situation, to comply with 14 CFR 91.403(c), the 
operator must request approval of an alternative method of compliance 
(AMOC) in accordance with the provisions of paragraph (j) of this 
proposed AD. The request should include a description of changes to the 
required inspections that will ensure the continued operational safety 
of the airplane.

Costs of Compliance

    We estimate that this proposed AD affects 15 airplanes of U.S. 
registry.
    We also estimate that it would take about 8 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 this proposed AD on U.S. operators to be $10,200, or $680 
per product.

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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    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 airworthiness 
directive (AD):

Fokker Services B.V.: Docket No. FAA-2015-3633; Directorate 
Identifier 2014-NM-097-AD.

[[Page 56415]]

(a) Comments Due Date

    We must receive comments by November 2, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Fokker Services B.V. Model F.27 Mark 200, 
300, 400, 500, 600, and 700 airplanes, certificated in any category, 
all serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Reason

    This AD was prompted by a design review conducted by Fokker 
Services B.V. that indicated no controlled bonding provisions were 
present on many critical locations outside the fuel tank or 
connected to the fuel tank wall. We are issuing this AD to prevent 
an ignition source in the fuel tank vapor space, which could result 
in a fuel tank explosion and consequent loss of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Installation

    Within 24 months after the effective date of this AD, install 
additional bonding provisions, in accordance with the Accomplishment 
Instructions of Fokker F27 Proforma Service Bulletin SBF27-28-072, 
Revision 1, dated March 6, 2014, including Fokker F27 Service 
Bulletin Appendix SBF27-28-072/APP01, including List of Drawings/
Part Lists, dated July 17, 2014.
