SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A300 B4– 601, B4–603, B4–605R, F4–605R, and C4–605R Variant F airplanes. The NPRM published in the Federal Register on April 14, 2014 (79 FR 20837). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2013–0286R1, dated June 6, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Model A300 B4–601, B4–603, B4–605R, PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 4769 F4–605R, and C4–605R Variant F airplanes. The MCAI states: Cracks were found on the lower side of rib 5 in the pylon box on A300 aeroplanes powered with General Electric engines. Investigations revealed that these cracks were due to the stresses resulting from the pressure applied by the thrust reverser cowl bumpers. This condition, if not detected and corrected, could affect the structural integrity of the aeroplane. Airbus developed an inspection programme to detect the cracks and associated actions to correct them. For the reasons described above, EASA issued AD 2013–0286 [http:// ad.easa.europa.eu/blob/easa_ad_2013_0286_ R1.pdf/AD_2013-0286R1_2] to require repetitive [HFEC] inspections of the pylon rib 5 on the left hand side (LH) and right hand (RH) side and, when cracks are detected, replacement of the affected structural part(s). [Replacement of all fittings terminates the repetitive HFEC inspections.] Since that [EASA] AD was issued, it was found that the [EASA] AD has inadvertently been made applicable to all A300–600 Models, which is incorrect. This [EASA] AD has been revised to reduce the Applicability to only the affected Models. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-02300004. Revision to Applicability Since the NPRM (79 FR 20837, April 14, 2014), was issued, we have determined that paragraph (c), ‘‘Applicability,’’ of this AD should not include Airbus Model A300 B4–620, B4–622, B4–622R, and F4–622R airplanes. We have removed these airplanes from paragraph (c) of this AD, and have revised the SUMMARY section and Costs of Compliance section of this final rule accordingly. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 20837, April 14, 2014) and the FAA’s response to each comment. Request for Credit for Modification FedEx requested that we revise paragraph (i) of the NPRM (79 FR 20837, April 14, 2014) to indicate that prior incorporation of the modification specified in Airbus Service Bulletin A300–54–6031, dated May 30, 1996, provides credit as a terminating action for the repetitive HFEC inspections specified in the NPRM. We find that clarification is necessary. Paragraph (h) of this AD already specifies that accomplishment of the E:\FR\FM\29JAR1.SGM 29JAR1 4770 Federal Register / Vol. 80, No. 19 / Thursday, January 29, 2015 / Rules and Regulations referenced modification is terminating action for the repetitive HFEC inspections required by paragraph (g)(1) of this AD for the modified side only. We have made no change to this AD in this regard. tkelley on DSK3SPTVN1PROD with RULES Request for Clarification UPS requested that we revise paragraphs (g)(2) and (h) of the NPRM (79 FR 20837, April 14, 2014) to clarify that replacement of fittings is to be done on the affected pylon or on the modified side only. UPS reasoned that one interpretation of the phrase ‘‘all the fittings’’ would be to replace the fittings in the left and right pylons, even though cracking was found in only one of the pylons. We agree to clarify. We have revised paragraphs (g)(2) and (h) of this AD to include the clarifications requested by the commenter. ‘‘Contacting the Manufacturer’’ Paragraph in This AD Since late 2006, we have included a standard paragraph titled ‘‘Airworthy Product’’ in all MCAI ADs in which the FAA develops an AD based on a foreign authority’s AD. We have become aware that some operators have misunderstood or misinterpreted the Airworthy Product paragraph to allow the owner/operator to use messages provided by the manufacturer as approval of deviations during the accomplishment of an ADmandated action. The Airworthy Product paragraph does not approve messages or other information provided by the manufacturer for deviations to the requirements of the AD-mandated actions. The Airworthy Product paragraph only addresses the requirement to contact the manufacturer for corrective actions for the identified unsafe condition and does not cover deviations from other AD requirements. However, deviations to AD-required actions are addressed in 14 CFR 39.17, and anyone may request the approval for an alternative method of compliance to the AD-required actions using the procedures found in 14 CFR 39.19. To address this misunderstanding and misinterpretation of the Airworthy Product paragraph, we have changed the paragraph and retitled it ‘‘Contacting the Manufacturer.’’ This paragraph now clarifies that for any requirement in this AD to obtain corrective actions from a manufacturer, the actions must be accomplished using a method approved by the FAA, the EASA, or Airbus’s EASA Design Organization Approval (DOA). The Contacting the Manufacturer paragraph also clarifies that, if approved VerDate Sep<11>2014 16:36 Jan 28, 2015 Jkt 235001 by the DOA, the approval must include the DOA-authorized signature. The DOA signature indicates that the data and information contained in the document are EASA-approved, which is also FAAapproved. Messages and other information provided by the manufacturer that do not contain the DOA-authorized signature approval are not EASA-approved, unless EASA directly approves the manufacturer’s message or other information. This clarification does not remove flexibility previously afforded by the Airworthy Product paragraph. Consistent with long-standing FAA policy, such flexibility was never intended for required actions. This is also consistent with the recommendation of the Airworthiness Directive Implementation Aviation Rulemaking Committee to increase flexibility in complying with ADs by identifying those actions in manufacturers’ service instructions that are ‘‘Required for Compliance’’ with ADs. We continue to work with manufacturers to implement this recommendation. But once we determine that an action is required, any deviation from the requirement must be approved as an alternative method of compliance. We also have decided not to include a generic reference to either the ‘‘delegated agent’’ or ‘‘design approval holder (DAH) with State of Design Authority design organization approval,’’ but instead we have provided the specific delegation approval granted by the State of Design Authority for the DAH. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (79 FR 20837, April 14, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 20837, April 14, 2014). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information We reviewed Airbus Service Bulletin A300–54–6031, dated May 30, 1996; and Airbus Service Bulletin A300–54– 6034, Revision 02, dated August 26, PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 2013. The service information describes procedures for repetitive HFEC inspections for cracking of the lower side of rib 5 in the LH and RH pylon box and replacing certain fittings. You can find this information at http:// www.regulations.gov by searching for and locating Docket No. FAA–2014– 0230. Costs of Compliance We estimate that this AD affects 54 airplanes of U.S. registry. We also estimate that it will take about 9 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 $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $41,310, or $765 per product. In addition, we estimate that any necessary follow-on actions will take about 32 work-hours and require parts costing $2,450, for a cost of $5,170 per product. We have no way of determining the number of aircraft that might need this action. 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; E:\FR\FM\29JAR1.SGM 29JAR1 Federal Register / Vol. 80, No. 19 / Thursday, January 29, 2015 / Rules and Regulations 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.

SUPPLEMENTARY INFORMATION: Discussion Transport Canada, which is the aviation authority for Canada, has issued AD No. CF–2014–38, dated October 20, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for Viking Air Limited Models DHC–2 Mk. I, DHC–2 Mk. II, and DHC– 2 Mk. III airplanes. The MCAI states: There has been an in-service report of failed MS21042 locknuts on the horizontal stabilizer attach bracket of a DHC–2 Mk. I aeroplane. Laboratory examinations of these nuts found intergranular fractures typical of hydrogen embrittlement possibly due to the introduction of hydrogen during the manufacturing process. Failure of these nuts could result in detachment of the horizontal stabilizer and loss of control of the aeroplane. This AD mandates the inspection and replacement, of the horizontal stabilizer attach bracket MS21042 locknuts. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2015–0096. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 Relevant Service Information Viking Air Limited has issued Viking Alert Service Bulletin No. V2/0007, Revision ‘NC’, dated April 29, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. The service bulletin describes procedures to inspect and replace the horizontal stabilizer attach bracket locknuts. You can find this service information on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2015– 0096. FAA’s Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because failure of any locknut on the horizontal stabilizer attach bracket could result in detachment of the horizontal stabilizer and consequent loss of control. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2015–0096; Directorate Identifier 2014–CE–040– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Model A300 B4-601, B4-603, B4-605R, F4-605R, and C4-605R Variant 
F airplanes. This AD was prompted by reports of cracking found in the 
pylon box, which was due to the stresses resulting from the pressure 
applied by the thrust reverser cowl bumpers. This AD requires 
repetitive high frequency eddy current (HFEC) inspections for cracking; 
and replacement of all fittings if necessary, which terminates the 
repetitive HFEC inspections for the modified side only. We are issuing 
this AD to detect and correct cracks of the pylon rib 5, which could 
result in reduced structural integrity of the airplane.

DATES: This AD becomes effective March 5, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 5, 
2015.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Airbus Model A300 
B4-601, B4-603, B4-605R, F4-605R, and C4-605R Variant F airplanes. The 
NPRM published in the Federal Register on April 14, 2014 (79 FR 20837).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0286R1, dated June 6, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A300 B4-601, B4-603, B4-605R, F4-605R, and C4-605R Variant F airplanes. 
The MCAI states:

    Cracks were found on the lower side of rib 5 in the pylon box on 
A300 aeroplanes powered with General Electric engines.
    Investigations revealed that these cracks were due to the 
stresses resulting from the pressure applied by the thrust reverser 
cowl bumpers.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    Airbus developed an inspection programme to detect the cracks 
and associated actions to correct them.
    For the reasons described above, EASA issued AD 2013-0286 
[http://ad.easa.europa.eu/blob/easa_ad_2013_0286_R1.pdf/AD_2013-0286R1_2] to require repetitive [HFEC] inspections of the pylon rib 
5 on the left hand side (LH) and right hand (RH) side and, when 
cracks are detected, replacement of the affected structural part(s). 
[Replacement of all fittings terminates the repetitive HFEC 
inspections.]
    Since that [EASA] AD was issued, it was found that the [EASA] AD 
has inadvertently been made applicable to all A300-600 Models, which 
is incorrect. This [EASA] AD has been revised to reduce the 
Applicability to only the affected Models.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0230-0004.

Revision to Applicability

    Since the NPRM (79 FR 20837, April 14, 2014), was issued, we have 
determined that paragraph (c), ``Applicability,'' of this AD should not 
include Airbus Model A300 B4-620, B4-622, B4-622R, and F4-622R 
airplanes. We have removed these airplanes from paragraph (c) of this 
AD, and have revised the SUMMARY section and Costs of Compliance 
section of this final rule accordingly.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 20837, April 14, 2014) and the FAA's response to each comment.

Request for Credit for Modification

    FedEx requested that we revise paragraph (i) of the NPRM (79 FR 
20837, April 14, 2014) to indicate that prior incorporation of the 
modification specified in Airbus Service Bulletin A300-54-6031, dated 
May 30, 1996, provides credit as a terminating action for the 
repetitive HFEC inspections specified in the NPRM.
    We find that clarification is necessary. Paragraph (h) of this AD 
already specifies that accomplishment of the

[[Page 4770]]

referenced modification is terminating action for the repetitive HFEC 
inspections required by paragraph (g)(1) of this AD for the modified 
side only. We have made no change to this AD in this regard.

Request for Clarification

    UPS requested that we revise paragraphs (g)(2) and (h) of the NPRM 
(79 FR 20837, April 14, 2014) to clarify that replacement of fittings 
is to be done on the affected pylon or on the modified side only. UPS 
reasoned that one interpretation of the phrase ``all the fittings'' 
would be to replace the fittings in the left and right pylons, even 
though cracking was found in only one of the pylons.
    We agree to clarify. We have revised paragraphs (g)(2) and (h) of 
this AD to include the clarifications requested by the commenter.

``Contacting the Manufacturer'' Paragraph in This AD

    Since late 2006, we have included a standard paragraph titled 
``Airworthy Product'' in all MCAI ADs in which the FAA develops an AD 
based on a foreign authority's AD.
    We have become aware that some operators have misunderstood or 
misinterpreted the Airworthy Product paragraph to allow the owner/
operator to use messages provided by the manufacturer as approval of 
deviations during the accomplishment of an AD-mandated action. The 
Airworthy Product paragraph does not approve messages or other 
information provided by the manufacturer for deviations to the 
requirements of the AD-mandated actions. The Airworthy Product 
paragraph only addresses the requirement to contact the manufacturer 
for corrective actions for the identified unsafe condition and does not 
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request 
the approval for an alternative method of compliance to the AD-required 
actions using the procedures found in 14 CFR 39.19.
    To address this misunderstanding and misinterpretation of the 
Airworthy Product paragraph, we have changed the paragraph and retitled 
it ``Contacting the Manufacturer.'' This paragraph now clarifies that 
for any requirement in this AD to obtain corrective actions from a 
manufacturer, the actions must be accomplished using a method approved 
by the FAA, the EASA, or Airbus's EASA Design Organization Approval 
(DOA).
    The Contacting the Manufacturer paragraph also clarifies that, if 
approved by the DOA, the approval must include the DOA-authorized 
signature. The DOA signature indicates that the data and information 
contained in the document are EASA-approved, which is also FAA-
approved. Messages and other information provided by the manufacturer 
that do not contain the DOA-authorized signature approval are not EASA-
approved, unless EASA directly approves the manufacturer's message or 
other information.
    This clarification does not remove flexibility previously afforded 
by the Airworthy Product paragraph. Consistent with long-standing FAA 
policy, such flexibility was never intended for required actions. This 
is also consistent with the recommendation of the Airworthiness 
Directive Implementation Aviation Rulemaking Committee to increase 
flexibility in complying with ADs by identifying those actions in 
manufacturers' service instructions that are ``Required for 
Compliance'' with ADs. We continue to work with manufacturers to 
implement this recommendation. But once we determine that an action is 
required, any deviation from the requirement must be approved as an 
alternative method of compliance.
    We also have decided not to include a generic reference to either 
the ``delegated agent'' or ``design approval holder (DAH) with State of 
Design Authority design organization approval,'' but instead we have 
provided the specific delegation approval granted by the State of 
Design Authority for the DAH.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 20837, April 14, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 20837, April 14, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information

    We reviewed Airbus Service Bulletin A300-54-6031, dated May 30, 
1996; and Airbus Service Bulletin A300-54-6034, Revision 02, dated 
August 26, 2013. The service information describes procedures for 
repetitive HFEC inspections for cracking of the lower side of rib 5 in 
the LH and RH pylon box and replacing certain fittings. You can find 
this information at http://www.regulations.gov by searching for and 
locating Docket No. FAA-2014-0230.

Costs of Compliance

    We estimate that this AD affects 54 airplanes of U.S. registry.
    We also estimate that it will take about 9 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 $0 per product. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $41,310, or $765 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 32 work-hours and require parts costing $2,450, for a cost 
of $5,170 per product. We have no way of determining the number of 
aircraft that might need this action.

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;

[[Page 4771]]

    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.

unless already done.

(g) Inspection and Replacement

    (1) Before the accumulation of 15,000 total flight hours since 
the airplane's first flight, or within 6,000 flight hours after the 
effective date of this AD, whichever occurs later: Do a high 
frequency eddy current (HFEC) inspection for cracking on the lower 
area of rib 5 on the left-hand and right-hand side pylons, in 
accordance with the Accomplishment Instructions of Airbus Service 
Bulletin A300-54-6034, Revision 02, dated August 26, 2013. Repeat 
the inspection thereafter at intervals not to exceed 15,000 flight 
hours.
    (2) If any crack is found during any inspection required by 
paragraph (g)(1) of this AD, before further flight, replace all the 
fittings--on the affected pylon only--with new standard fittings, in 
accordance with the Accomplishment Instructions of Airbus Service 
Bulletin A300-54-6031, dated May 30, 1996.

(h) Terminating Action

    Replacement of all fittings as required by paragraph (g)(2) of 
this AD; or modification of pylons in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A300-54-6031, 
dated May 30, 1996; terminates the repetitive HFEC inspections 
required by paragraph (g)(1) of this AD for the modified side only.

(i) Credit for Previous Actions

    This paragraph provides credit for the inspections required by 
paragraph (g)(1) of this AD, if those actions were performed before 
the effective date of this AD using Airbus Service Bulletin A300-54-
6034, Revision 01, dated September 14, 1999, which is not 
incorporated by reference in this AD.
