DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2012–1000; Directorate Identifier 2012–NM–065–AD; Amendment 39–17460; AD 2013–10–07] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4–601, B4–603, B4–620, B4–605R, and B4–622R airplanes. This AD was prompted by a report that the door frame shells of passenger doors 2 and 4 may not have sufficient structural strength to enable the airplane to operate safely. This AD requires reinforcing the door frame shells of passenger doors 2 and 4 on both sides of the fuselage. We are issuing this AD to prevent structural failure of the door frame shells, which could result in in-flight decompression of the airplane and consequent injury to passengers. DATES: This AD becomes effective July 5, 2013. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 5, 2013.

SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on September 24, 2012 (77 FR 58785). That NPRM proposed to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (MCAI) states: As a result of the Extended Service Goal 2 exercise (ESG2) it was shown that the door frame shells of passenger doors 2 and 4 (both sides of the aeroplane) may not have sufficient structural strength to enable the aeroplane to operate safety beyond ESG1 (Extended Service Goal 1 equal to 42,500 Flight Cycles—FC or 89,000 Flight Hours— FH) and up to ESG2 (Extended Service Goal 2 equal to 51,000 FC or 89,000 FH) limits. This condition, if not corrected, could lead to structural failure of the affected door shells, possibly resulting in in-flight decompression of the aeroplane and consequent injury to occupants. For the reasons stated above, this [European Aviation Safety Agency (EASA)] AD requires the reinforcement at door frame shells of passenger doors 2 and 4. 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 have considered the comments received. Request for a Copy of the Service Information FedEx requested that copies of Airbus Service Bulletin A300–53–6170, dated May 16, 2011, be provided to understand the full intent of the modification. FedEx stated that copies of Airbus Service Bulletin A300–53– 6170, dated May 16, 2011, are not available to operators without paying for the modification kit for ESG–2 operations. As stated in the NPRM (77 FR 58785, September 24, 2012), copies of the referenced service information may be PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 reviewed at the FAA, Transport Airplane Directorate, 1601 Lind Avenue SW., Renton, WA.

After publication of the final rule, you may examine the AD docket on the Internet at http://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. Request for Exception for Certain Passenger Doors FedEx requested an exception for the passenger door 2 on airplanes modified from passenger to freighter per supplemental type certificate (STC) ST01431NY* (http://rgl.faa.gov/ Regulatory_and_Guidance_Library/ rgstc.nsf/0/9F0C4BC1162AA3CE8625 71B2005F355C?OpenDocument& Highlight=st01431ny). FedEx stated that the passenger door 2 has been removed from the modified airplanes to install the upper deck cargo door in these positions. FedEx noted that applicability to the remaining door 4 would remain in effect. We disagree with the commenter’s request. Operators should work with the STC holder to evaluate and determine what actions might be necessary to address the unsafe condition if it exists. Operators may request approval of an alternative method of compliance to address this evaluation. No change has been made to the AD in this regard. Conclusion We reviewed the available data, including the comments received, 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 NPRM (77 FR 58785, September 24, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 58785, September 24, 2012). Costs of Compliance We estimate that this AD will affect 124 products of U.S. registry. We also estimate that it will take about 400 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $10,000 E:\FR\FM\30MYR1.SGM 30MYR1 32346 Federal Register / Vol. 78, No. 104 / Thursday, May 30, 2013 / Rules and Regulations Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

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. rmajette on DSK2TPTVN1PROD with RULES per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $5,456,000, or $44,000 per product. List of Subjects in 14 CFR Part 39 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.

Discussion Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. The Air Line Pilots Association (ALPA) stated that it supports the NPRM (77 FR 66760, November 7, 2012). ADDRESSES: We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on November 7, 2012 (77 FR 66760). That NPRM 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, has issued EASA Airworthiness Directive 2011–0242, dated December 19, 2011 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (MCAI) states: Several operators have reported cases of burning smell and/or smoke in the cockpit during cruise phase leading in some cases to diversion. Findings have shown that the cause of these events is the burning of the SaintGobain Sully (SGS) windshield connector terminal block. This condition, if not corrected, could significantly increase the flight crew workload which would, under some flight phases and/or circumstances, constitute an unsafe condition. For the reasons described above, this [EASA] AD requires the identification of the installed windshields and replacement of the affected part. * * * * * You may obtain further information by examining the MCAI in the AD docket. Revised Service Information Since the NPRM (77 FR 66760, November 7, 2012) was published, we have received the following service information: • Airbus Mandatory Service Bulletin A330–56–3009, Revision 02, including Appendix 01, dated February 8, 2012; • Airbus Mandatory Service Bulletin A340–56–4008, Revision 01, including PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 Request To Revise Applicability Airbus requested that the applicability stated in the NPRM (77 FR 66760, November 7, 2012) be revised to state the generic Model ‘‘A330–200/– 300’’ and ‘‘A340–500/–600’’ series airplanes instead of the specific airplane models. Airbus stated that the actions of the NPRM are actually required for all the series airplanes instead of only the models stated in the NPRM. We disagree. The models stated in paragraph (c) of the NPRM (77 FR 66760, November 7, 2012) correspond to the model and series airplanes validated by the FAA and identified in an FAA type certificate data sheet (TCDS). Some series airplanes that were identified in the MCAI are not listed on any FAA TCDS and cannot be imported and placed on the U.S. register until that model is validated and identified on an FAA TCDS. If a model identified in the MCAI is identified on an FAA TCDS in the future, we might consider additional rulemaking. We have not changed this AD in this regard. Conclusion We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously and minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (77 FR 66760, November 7, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 66760, November 7, 2012).

Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A300 B4-601, B4-603, B4-620, B4-605R, and B4-622R 
airplanes. This AD was prompted by a report that the door frame shells 
of passenger doors 2 and 4 may not have sufficient structural strength 
to enable the airplane to operate safely. This AD requires reinforcing 
the door frame shells of passenger doors 2 and 4 on both sides of the 
fuselage. We are issuing this AD to prevent structural failure of the 
door frame shells, which could result in in-flight decompression of the 
airplane and consequent injury to passengers.

DATES: This AD becomes effective July 5, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 5, 
2013.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on September 24, 2012 
(77 FR 58785). That NPRM proposed to correct an unsafe condition for 
the specified products. The Mandatory Continuing Airworthiness 
Information (MCAI) states:

    As a result of the Extended Service Goal 2 exercise (ESG2) it 
was shown that the door frame shells of passenger doors 2 and 4 
(both sides of the aeroplane) may not have sufficient structural 
strength to enable the aeroplane to operate safety beyond ESG1 
(Extended Service Goal 1 equal to 42,500 Flight Cycles--FC or 89,000 
Flight Hours--FH) and up to ESG2 (Extended Service Goal 2 equal to 
51,000 FC or 89,000 FH) limits.
    This condition, if not corrected, could lead to structural 
failure of the affected door shells, possibly resulting in in-flight 
decompression of the aeroplane and consequent injury to occupants.
    For the reasons stated above, this [European Aviation Safety 
Agency (EASA)] AD requires the reinforcement at door frame shells of 
passenger doors 2 and 4.

    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 have considered the comments received.

Request for a Copy of the Service Information

    FedEx requested that copies of Airbus Service Bulletin A300-53-
6170, dated May 16, 2011, be provided to understand the full intent of 
the modification. FedEx stated that copies of Airbus Service Bulletin 
A300-53-6170, dated May 16, 2011, are not available to operators 
without paying for the modification kit for ESG-2 operations.
    As stated in the NPRM (77 FR 58785, September 24, 2012), copies of 
the referenced service information may be reviewed at the FAA, 
Transport Airplane Directorate, 1601 Lind Avenue SW., Renton, WA. No 
change has been made to the AD in this regard. After publication of the 
final rule, you may examine the AD docket on the Internet at http://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.

Request for Exception for Certain Passenger Doors

    FedEx requested an exception for the passenger door 2 on airplanes 
modified from passenger to freighter per supplemental type certificate 
(STC) ST01431NY* (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/9F0C4BC1162AA3CE862571B2005F355C?OpenDocument&Highlight=st01431ny). 
FedEx stated that the passenger door 2 has been removed from the 
modified airplanes to install the upper deck cargo door in these 
positions. FedEx noted that applicability to the remaining door 4 would 
remain in effect.
    We disagree with the commenter's request. Operators should work 
with the STC holder to evaluate and determine what actions might be 
necessary to address the unsafe condition if it exists. Operators may 
request approval of an alternative method of compliance to address this 
evaluation. No change has been made to the AD in this regard.

Conclusion

    We reviewed the available data, including the comments received, 
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 
NPRM (77 FR 58785, September 24, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 58785, September 24, 2012).

Costs of Compliance

    We estimate that this AD will affect 124 products of U.S. registry. 
We also estimate that it will take about 400 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $10,000

[[Page 32346]]

per product. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD to the 
U.S. operators to be $5,456,000, or $44,000 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 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

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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 AD:

2013-10-07 Airbus: Amendment 39-17460. Docket No. FAA-2012-1000; 
Directorate Identifier 2012-NM-065-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective July 5, 
2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, B4-
605R, and B4-622R airplanes; certificated in any category; all 
serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Reason

    This AD was prompted by a report that the door frame shells of 
passenger doors 2 and 4 may not have sufficient structural strength 
to enable the airplane to operate safely. We are issuing this AD to 
prevent structural failure of the door frame shells, which could 
result in in-flight decompression of the airplane and consequent 
injury to passengers.

(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) Reinforcement

    Before the accumulation of 42,500 total flight cycles or within 
2,000 flight cycles after the effective date of this AD, whichever 
occurs later: Do the actions specified in paragraph (g)(1) or (g)(2) 
of this AD, as applicable.
    (1) For Model A300 B4-622R airplanes: Reinforce the door frame 
shells of passenger doors 2 and 4 on both sides of the fuselage, in 
accordance with the Accomplishment Instructions of Airbus Service 
Bulletin A300-53-6170, dated May 16, 2011.
    (2) For Model A300 B4-601, B4-603, B4-620, and B4-605R 
airplanes: Reinforce the door frame shells of passenger doors 2 and 
4 on both sides of the fuselage, using a method approved by either 
the Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA; or the European Aviation Safety Agency (EASA) (or 
its delegated agent).

(h) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
