DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2016–5591; Directorate Identifier 2014–NM–193–AD; Amendment 39–18651; AD 2016–19–02] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are superseding Airworthiness Directive (AD) 2005–15– 07 for certain Airbus Model A320–111 airplanes and Model A320–200 series airplanes. AD 2005–15–07 required installing insulator and cable ties to the electrical cables of the S routes at the gaps in the raceway in the wing trailing edge and the wing tip and wing root areas. This new AD requires additional modifications in the trailing edges of both wings. This new AD also removes airplanes from the applicability. This AD was prompted by reports of wire chafing in the left-hand wing trailing edge. We are issuing this AD to prevent wire chafing in the trailing edge of the wings, which could result in a short circuit in the vicinity of the fuel tanks, consequently resulting in a potential source of ignition in a fuel tank vapor space and consequent fuel tank explosion. SUMMARY: This AD is effective October 24, 2016. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 24, 2016.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2005–15–07, Amendment 39–14196 (70 FR 43024, July 26, 2005) (‘‘AD 2005–15–07’’). AD 2005–15–07 applied to certain Airbus Model A320–111 airplanes and Model A320–200 series airplanes. The NPRM published in the Federal Register on April 20, 2016 (81 FR 23199). The NPRM was prompted by reports of wire chafing in the left-hand wing trailing edge. The NPRM proposed to continue to require installing insulator and cable ties to the electrical cables of the S routes at the gaps in the raceway in the wing trailing edge and the wing tip and PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 wing root areas. The NPRM proposed to require additional modifications in the trailing edges of both wings. The NPRM also proposed to remove airplanes from the applicability. We are issuing this AD to prevent wire chafing in the trailing edge of the wings, which could result in a short circuit in the vicinity of the fuel tanks, consequently resulting in a potential source of ignition in a fuel tank vapor space and consequent fuel tank explosion. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014–0198, dated September 5, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Model A320–211, –212, and –231 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. Prompted by that regulation, the results of an Airbus review of the A320 type design identified, on certain aeroplanes, a possible ignition source in fuel tank vapour space(s). That condition, if not corrected, could result in a fuel tank explosion and consequent loss of the aeroplane. It was, therefore, decided to modify the cable routes of the wing trailing edge, aft of the rear spar and wing tip of those aeroplanes, to be applied in service in accordance with the instructions of Airbus Service Bulletin (SB) A320–24–1062 Revision 05. Following that decision, DGAC France issued AD F–2004–173 (EASA approval number 2004–10570) to require that modification. After that AD was issued, it was found that additional work, introduced by Airbus SB A320–24–1062 Revision 05, was not included as part of the normal accomplishment instructions, which meant that the additional work might not be accomplished. Consequently, EASA issued AD 2008–0051, retaining the requirements of DGAC France AD F–2004–173 [which corresponds to FAA AD 2005–15–07], which was superseded, and required the accomplishment of the additional work in accordance with the instructions of Airbus SB A320–24–1062 Revision 06. EASA AD 2008–0051 was revised to reduce the Applicability and to add a clarification to paragraph (2). After EASA AD 2008–0051R1 was issued, some operators reported wire chafing in the left hand wing trailing edge. Investigation E:\FR\FM\19SER1.SGM 19SER1 64052 Federal Register / Vol. 81, No. 181 / Monday, September 19, 2016 / Rules and Regulations established that the wire chafing, initiated at raceway gaps, was either due to maintenance action(s), or to structure vibrations. Prompted by these findings, Airbus developed two modifications to prevent any further wire chafing by introducing an additional protection at raceway gaps and a new cable standard in the trailing edges of both wings. Airbus published SB A320–92–1049 and SB A320–92–1052 to make these modifications available for in-service application. At the time of incorporation of Airbus SB A320–24–1062, these two modifications were considered recommended only. EASA recently determined that this condition, if not corrected, could lead to a short circuit on 115 volts in the vicinity of fuel tanks, consequently creating another risk of ignition source in a fuel tank vapour space. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2008–0051R1, which is superseded, and requires modifications to install the additional anti-chafing protection and the new cable standard. This AD also removes Model A320– 214, –232, and –233 airplanes from the applicability because those airplane models have been modified in production or in service. This AD also removes Model A320–111 airplanes from the applicability because those airplanes are no longer on the U.S. type certificate data sheet (there are no more A320–111 airplanes in service in the U.S. and none in storage). 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–2016– 5591. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion rmajette on DSK2TPTVN1PROD with RULES We reviewed the available data and determined that air safety and the public interest require adopting this 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 NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 We reviewed Airbus Service Bulletins A320–92–1049, Revision 01, dated November 28, 2011; A320–92–1052, dated December 5, 2007; and A320–24– VerDate Sep<11>2014 14:11 Sep 16, 2016 Jkt 238001 1062, Revision 07, dated November 28, 2011. Airbus Service Bulletin A320–92– 1049, Revision 01, dated November 28, 2011, describes procedures for installing the additional anti-chafing protection. Airbus Service Bulletin A320–92– 1052, dated December 5, 2007, describes procedures for replacing the current electrical cable with the new standard one. Airbus Service Bulletin A320–24– 1062, Revision 07, dated November 28, 2011, describes procedures for installing insulator and cable ties to the electrical cables of the S routes at the gaps in the raceway in the wing trailing edge and the wing tip and wing root areas. 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. Costs of Compliance We estimate that this AD affects 47 airplanes of U.S. registry. The actions required by AD 2005–15– 07, and retained in this AD take about 35 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost about $0 per product. Based on these figures, the estimated cost of the actions that were required by AD 2005–15–07 is $2,975 per product. We also estimate that it would take about 76 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $13,000 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $914,620, or $19,460 per product. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 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.

SUMMARY: We are superseding Airworthiness Directive (AD) 2005-15-07 for 
certain Airbus Model A320-111 airplanes and Model A320-200 series 
airplanes. AD 2005-15-07 required installing insulator and cable ties 
to the electrical cables of the S routes at the gaps in the raceway in 
the wing trailing edge and the wing tip and wing root areas. This new 
AD requires additional modifications in the trailing edges of both 
wings. This new AD also removes airplanes from the applicability. This 
AD was prompted by reports of wire chafing in the left-hand wing 
trailing edge. We are issuing this AD to prevent wire chafing in the 
trailing edge of the wings, which could result in a short circuit in 
the vicinity of the fuel tanks, consequently resulting in a potential 
source of ignition in a fuel tank vapor space and consequent fuel tank 
explosion.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2005-15-07, Amendment 39-14196 (70 FR 43024, 
July 26, 2005) (``AD 2005-15-07''). AD 2005-15-07 applied to certain 
Airbus Model A320-111 airplanes and Model A320-200 series airplanes. 
The NPRM published in the Federal Register on April 20, 2016 (81 FR 
23199). The NPRM was prompted by reports of wire chafing in the left-
hand wing trailing edge. The NPRM proposed to continue to require 
installing insulator and cable ties to the electrical cables of the S 
routes at the gaps in the raceway in the wing trailing edge and the 
wing tip and wing root areas. The NPRM proposed to require additional 
modifications in the trailing edges of both wings. The NPRM also 
proposed to remove airplanes from the applicability. We are issuing 
this AD to prevent wire chafing in the trailing edge of the wings, 
which could result in a short circuit in the vicinity of the fuel 
tanks, consequently resulting in a potential source of ignition in a 
fuel tank vapor space and consequent fuel tank explosion.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0198, dated September 5, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A320-211, -212, and -231 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.
    Prompted by that regulation, the results of an Airbus review of 
the A320 type design identified, on certain aeroplanes, a possible 
ignition source in fuel tank vapour space(s). That condition, if not 
corrected, could result in a fuel tank explosion and consequent loss 
of the aeroplane.
    It was, therefore, decided to modify the cable routes of the 
wing trailing edge, aft of the rear spar and wing tip of those 
aeroplanes, to be applied in service in accordance with the 
instructions of Airbus Service Bulletin (SB) A320-24-1062 Revision 
05. Following that decision, DGAC France issued AD F-2004-173 (EASA 
approval number 2004-10570) to require that modification.
    After that AD was issued, it was found that additional work, 
introduced by Airbus SB A320-24-1062 Revision 05, was not included 
as part of the normal accomplishment instructions, which meant that 
the additional work might not be accomplished. Consequently, EASA 
issued AD 2008-0051, retaining the requirements of DGAC France AD F-
2004-173 [which corresponds to FAA AD 2005-15-07], which was 
superseded, and required the accomplishment of the additional work 
in accordance with the instructions of Airbus SB A320-24-1062 
Revision 06. EASA AD 2008-0051 was revised to reduce the 
Applicability and to add a clarification to paragraph (2).
    After EASA AD 2008-0051R1 was issued, some operators reported 
wire chafing in the left hand wing trailing edge. Investigation

[[Page 64052]]

established that the wire chafing, initiated at raceway gaps, was 
either due to maintenance action(s), or to structure vibrations.
    Prompted by these findings, Airbus developed two modifications 
to prevent any further wire chafing by introducing an additional 
protection at raceway gaps and a new cable standard in the trailing 
edges of both wings.
    Airbus published SB A320-92-1049 and SB A320-92-1052 to make 
these modifications available for in-service application. At the 
time of incorporation of Airbus SB A320-24-1062, these two 
modifications were considered recommended only.
    EASA recently determined that this condition, if not corrected, 
could lead to a short circuit on 115 volts in the vicinity of fuel 
tanks, consequently creating another risk of ignition source in a 
fuel tank vapour space.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2008-0051R1, which is superseded, and 
requires modifications to install the additional anti-chafing 
protection and the new cable standard.

    This AD also removes Model A320-214, -232, and -233 airplanes from 
the applicability because those airplane models have been modified in 
production or in service. This AD also removes Model A320-111 airplanes 
from the applicability because those airplanes are no longer on the 
U.S. type certificate data sheet (there are no more A320-111 airplanes 
in service in the U.S. and none in storage). 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-2016-5591.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM 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 this 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 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Service Bulletins A320-92-1049, Revision 01, 
dated November 28, 2011; A320-92-1052, dated December 5, 2007; and 
A320-24-1062, Revision 07, dated November 28, 2011.
    Airbus Service Bulletin A320-92-1049, Revision 01, dated November 
28, 2011, describes procedures for installing the additional anti-
chafing protection.
    Airbus Service Bulletin A320-92-1052, dated December 5, 2007, 
describes procedures for replacing the current electrical cable with 
the new standard one.
    Airbus Service Bulletin A320-24-1062, Revision 07, dated November 
28, 2011, describes procedures for installing insulator and cable ties 
to the electrical cables of the S routes at the gaps in the raceway in 
the wing trailing edge and the wing tip and wing root areas.
    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.

Costs of Compliance

    We estimate that this AD affects 47 airplanes of U.S. registry.
    The actions required by AD 2005-15-07, and retained in this AD take 
about 35 work-hours per product, at an average labor rate of $85 per 
work-hour. Required parts cost about $0 per product. Based on these 
figures, the estimated cost of the actions that were required by AD 
2005-15-07 is $2,975 per product.
    We also estimate that it would take about 76 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts would cost about $13,000 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $914,620, or $19,460 per product.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.

List of Subjects in 14 CFR Part 39
