ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300–600 series airplanes. This proposed 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 engines’ thrust reverser cowl bumpers. This proposed AD would require repetitive high frequency eddy current (HFEC) inspections for cracking, and replacement of all fittings if necessary. Replacement of all fittings would terminate the repetitive HFEC inspections. We are proposing this AD to detect and correct cracks of the pylon rib 5, which could result in reduced structural integrity of the airplane.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0286, dated December 4, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. 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, this [EASA] AD requires 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 would terminate the repetitive HFEC inspections.] You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0230. mstockstill on DSK4VPTVN1PROD with PROPOSALS Relevant Service Information Airbus has issued the following service bulletins. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. • Airbus Service Bulletin A300–54– 6031, dated May 30, 1996. • Airbus Mandatory Service Bulletin A300–54–6034, Revision 02, dated August 26, 2013. VerDate Mar<15>2010 16:59 Apr 11, 2014 Jkt 232001 FAA’s Determination and Requirements of This Proposed AD products identified in this rulemaking action. 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. 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. Differences Between This Proposed AD and the MCAI or Service Information While paragraph (2) of EASA AD 2013–0286, dated December 4, 2013, gives a compliance time of within 250 flight hours to replace fittings, this AD requires replacement of those fitting before further flight. Costs of Compliance We estimate that this proposed AD affects 129 airplanes of U.S. registry. We also estimate that it would take about 9 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost $0 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $98,685 or $765 per product. In addition, we estimate that any necessary follow-on actions would 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 PO 00000 Frm 00021 Fmt 4702 Sfmt 4702 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A300-600 series airplanes. This proposed 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 engines' 
thrust reverser cowl bumpers. This proposed AD would require repetitive 
high frequency eddy current (HFEC) inspections for cracking, and 
replacement of all fittings if necessary. Replacement of all fittings 
would terminate the repetitive HFEC inspections. We are proposing this 
AD to detect and correct cracks of the pylon rib 5, which could result 
in reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by May 29, 2014.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0286, dated December 4, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. 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, this [EASA] AD requires 
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 would terminate the repetitive HFEC inspections.]

    You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov by searching for and locating it in Docket No. 
FAA-2014-0230.

Relevant Service Information

    Airbus has issued the following service bulletins. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI.
     Airbus Service Bulletin A300-54-6031, dated May 30, 1996.
     Airbus Mandatory Service Bulletin A300-54-6034, Revision 
02, dated August 26, 2013.

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.

Differences Between This Proposed AD and the MCAI or Service 
Information

    While paragraph (2) of EASA AD 2013-0286, dated December 4, 2013, 
gives a compliance time of within 250 flight hours to replace fittings, 
this AD requires replacement of those fitting before further flight.

Costs of Compliance

    We estimate that this proposed AD affects 129 airplanes of U.S. 
registry.
    We also estimate that it would take about 9 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $98,685 or $765 per product.
    In addition, we estimate that any necessary follow-on actions would 
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 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

    We must receive comments by May 29, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, B4-
622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F

[[Page 20839]]

(d) Subject

    Air Transport Association (ATA) of America Code 54, Nacelles/
Pylons.

(e) Reason

    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. 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
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 Mandatory 
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 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.

(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.

(j) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Branch, send it to ATTN: Dan Rodina, 
Aerospace Engineer, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, Washington 
98057-3356; telephone (425) 227-2125; fax (425) 227-1149. 
Information may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer, use these actions if they 
are FAA approved. Corrective actions are considered FAA-approved if 
they were approved by the State of Design Authority (or its 
delegated agent, or the DAH with a State of Design Authority's 
design organization approval). You are required to ensure the 
product is airworthy before it is returned to service.
