The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2017–0713; Directorate Identifier 2016–NM–199–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede Airworthiness Directive (AD) 2012–12– 12, for all Airbus Model A330–200, A330–200 Freighter, A330–300, A340– 200, and A340–300 series airplanes; and AD 2013–16–26 for all Airbus Model A330–200 Freighter, A330–200 and –300, and A340–200 and –300 series airplanes. AD 2012–12–12 requires repetitive inspections of the outer skin rivets of the cargo doors; repair if necessary; and other repetitive inspections. AD 2013–16–26 requires repetitive inspections of certain cargo doors, and repair if necessary. Since we issued AD 2012–12–12 and AD 2013– 16–26, we have determined that a new inspection procedure is necessary to address the unsafe condition. This proposed AD would continue to require repetitive inspections and repair if necessary. This proposed AD would add a one-time inspection and adjustment of certain hook gaps; reinforcement of the door frame structure; related investigative and corrective actions if necessary; and a modification, which would allow deferring reinforcement of the cargo door structure. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by September 25, 2017. mstockstill on DSK30JT082PROD with PROPOSALS SUMMARY: You may send comments, using the procedures found in 14 CFR ADDRESSES: VerDate Sep<11>2014 16:24 Aug 09, 2017 Jkt 241001 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion On June 7, 2012, we issued AD 2012– 12–12, Amendment 39–17092 (77 FR 37797, June 25, 2012) (‘‘AD 2012–12– 12’’), for all Airbus Model A330–200 series airplanes, Model A330–200 Freighter series airplanes, Model A330– 300 series airplanes, Model A340–200 series airplanes, and Model A340–300 series airplanes. AD 2012–12–12 was prompted by reports of sheared fasteners located on the outside skin of the forward cargo door and cracks on the frame fork ends, as well as cracks of the aft cargo door frame 64A. AD 2012– 12–12 requires a detailed inspection of the outer skin rivets at the frame fork ends of the forward and aft cargo doors for sheared, loose, and missing rivets; repair of the outer skin rivets if necessary; and other repetitive inspections. We issued AD 2012–12–12 to detect and correct sheared, loose, or missing fasteners on the forward and aft cargo door frame, which could result in the loss of structural integrity of the forward and aft cargo door. On August 9, 2013, we issued AD 2013–16–26, Amendment 39–17564 (78 FR 53640, August 30, 2013) (‘‘2013–16– 26’’), for all Airbus Model A330–200 Freighter series airplanes, Model A330– 200 and –300 series airplanes, and Model A340–200 and –300 series airplanes. AD 2013–16–26 was prompted by reports of cracked adjacent frame forks of a forward cargo door. AD 2013–16–26 requires repetitive detailed inspections for cracks and sheared, loose, or missing rivets of the forward cargo door and, for certain airplanes, of the aft cargo door, and repair if necessary. We issued AD 2013–16–26 to detect and correct cracked or ruptured cargo door frames, which could result in E:\FR\FM\10AUP1.SGM 10AUP1 Federal Register / Vol. 82, No. 153 / Thursday, August 10, 2017 / Proposed Rules mstockstill on DSK30JT082PROD with PROPOSALS reduced structural integrity of the forward or aft cargo door. Since we issued AD 2012–12–12 and AD 2013–16–26, we have determined that a new inspection procedure is necessary to address the unsafe condition. In addition, the manufacturer has released some terminating action modifications for the cargo door structure, and provided procedures that allow postponing the structural reinforcement modification, which terminate the repetitive inspections. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016–0188, dated September 21, 2016; corrected September 22, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’); to correct an unsafe condition for certain Airbus Model A330–200 and –300 series airplanes; Model A330–200 Freighter series airplanes; and Model A340–200, –300, –500, and –600 series airplanes. The MCAI states: Several cases of cracked forward (FWD) and aft (AFT) cargo door frames, as well as loose, lost, or sheared rivets, have been reported by operators. Investigation showed that these findings are due to the low margins with respect to fatigue requirements for the AFT/FWD cargo door internal structure. Further analysis determined that the cargo door hook adjustment is a contributing factor to this issue. In case of a cracked or ruptured (FWD or AFT) cargo door frame, the loads will be transferred to the remaining structural elements. However, the secondary load path is able to sustain those loads only for a limited number of flight cycles (FC). This condition, if not detected and corrected, could lead to rupture of adjacent vertical frames and consequent reduced structural integrity of the FWD or AFT cargo door, possibly resulting in a cargo door failure, decompression of the aeroplane and injury to occupants. To initially address this potential unsafe condition, Airbus issued Service Bulletin (SB) A330–52–3043 and SB A340–52–4053 and, consequently, DGAC [Direction ´ ´ Generale de l’Aviation Civile] France issued AD 2001–124(B) and AD 2001–126(B), requiring a special detailed inspection of A330 and A340 AFT cargo doors. Since those [DGAC] ADs were issued, prompted by new occurrences, Airbus issued Alert Operators Transmission (AOT) A330–52A3085, AOT A340–52A4092, AOT A330–52A3084, AOT A340–52A4091, AOT A330–A52L003–12, AOT 340–A52L004–12, AOT A330– A52L001–12 and AOT A340–A52L002–12, providing instructions to inspect the affected areas of both FWD and AFT cargo doors. Consequently, EASA issued AD 2011–0007 (later revised) [which corresponds to FAA AD 2012–12–12], and AD 2012–0274 [which corresponds to FAA AD 2013–16–26], to require repetitive detailed visual inspections of AFT and FWD cargo doors at specific frames and outer skin at all frame fork ends. VerDate Sep<11>2014 16:24 Aug 09, 2017 Jkt 241001 Since these EASA ADs were issued, Airbus published SB A330–52–3087, SB A330–52– 3095, SB A340–52–4095, SB A340–52–4101, SB A340–52–5020 and SB A340–52–5023, which took over the instructions of the above mentioned AOTs, and introduced revised thresholds and intervals. In addition, the inspection program was expanded to A340– 500/–600 aeroplanes. Taking into account experience from inspections accomplished in accordance with the applicable Airbus SBs at original issue (listed above), Airbus issued Revision 01 of these SBs. Consequently, EASA issued AD 2015– 0192, which superseded EASA AD 2011– 0007R1 and EASA AD 2012–0274, to require for each FWD and AFT cargo door, a onetime inspection/adjustment of the hook gaps ‘‘U’’ and ‘‘V’’, repetitive detailed inspections (DET) of all frame fork areas, frame head areas and outer skin areas to detect cracks or loose/sheared/missing fasteners, and, depending on findings, accomplishment of applicable corrective action(s). In addition, EASA AD 2015–0192 expanded the Applicability to Airbus A340–500/–600 aeroplanes. Since EASA AD 2015–0192 was issued, Airbus published Revision 02 of the inspection SBs, introducing high-frequency eddy-current inspection method for the frame forks structure. Airbus also determined that the interval for these repetitive inspections could be increased. In addition, Airbus released some modifications (mod) introducing reinforcements to the cargo door structure improving the fatigue characteristics. These modifications and associated SBs constitute terminating action for the required repetitive inspections. Furthermore, Airbus also published other SBs, introducing cold working after oversizing of the fastener holes as a means for structural reinforcement. Accomplishment of these SBs allows postponement of the required Point of Embodiment (Structural Modification Point) for the structural reinforcement modification SBs which terminate the repetitive inspection requirement. For the reasons described above, this [EASA] AD partially retains the requirements of EASA AD 2015–0192, which is superseded, and requires for each FWD and AFT cargo door initial and repetitive special detailed inspections (SDI) of all frame fork areas and detailed inspections (DET) of frame head areas and outer skin areas, and a onetime inspection/adjustment of the hook gaps ‘‘U’’ and ‘‘V’’ and, depending on findings, the accomplishment of applicable corrective action(s). Additionally, this [EASA] AD requires reinforcement of the cargo door frame structure, while accomplishment of a cold working modification allows to defer the reinforcement of the cargo door structure. It should be noted that additional inspections exist for the cargo doors, as specified in Airbus A330 ALS [Airworthiness Limitation Section] Part 2 task 523211–02–01 and task 523211–02–02, and in Airbus A340 ALS Part 2 Task 523211–02–01. This [EASA] AD is re-published to correct typographical errors when referencing Airbus SB A340–52–4118. PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 37361 Related investigative actions include detailed inspections and high frequency non-destructive test inspections. Corrective actions include reaming holes, bushing holes, replacing affected parts, and repairing cracks. Additional work includes a one-time inspection of the ‘‘U’’ and ‘‘V’’ hook gaps, and if necessary, an adjustment of the hook gaps.

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 VerDate Sep<11>2014 16:24 Aug 09, 2017 Jkt 241001 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 designs. Costs of Compliance We estimate that this proposed AD affects 73 airplanes of U.S. registry. We estimate that it would take up to 888 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 up to $126,420 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be up to $14,738,700, or up to $201,900 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. 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: PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 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.

This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the fuselage crown skin panels are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections, replacement, and applicable on-condition actions for certain fuselage crown skin panels. We are proposing this AD to address the unsafe condition on these products. SUMMARY: E:\FR\FM\10AUP1.SGM 10AUP1

[Docket No. FAA-2017-0713; Directorate Identifier 2016-NM-199-AD]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2012-12-
12, for all Airbus Model A330-200, A330-200 Freighter, A330-300, A340-
200, and A340-300 series airplanes; and AD 2013-16-26 for all Airbus 
Model A330-200 Freighter, A330-200 and -300, and A340-200 and -300 
series airplanes. AD 2012-12-12 requires repetitive inspections of the 
outer skin rivets of the cargo doors; repair if necessary; and other 
repetitive inspections. AD 2013-16-26 requires repetitive inspections 
of certain cargo doors, and repair if necessary. Since we issued AD 
2012-12-12 and AD 2013-16-26, we have determined that a new inspection 
procedure is necessary to address the unsafe condition. This proposed 
AD would continue to require repetitive inspections and repair if 
necessary. This proposed AD would add a one-time inspection and 
adjustment of certain hook gaps; reinforcement of the door frame 
structure; related investigative and corrective actions if necessary; 
and a modification, which would allow deferring reinforcement of the 
cargo door structure. We are proposing this AD to address the unsafe 
condition on these products.

DATES: We must receive comments on this proposed AD by September 25, 
2017.

Discussion

    On June 7, 2012, we issued AD 2012-12-12, Amendment 39-17092 (77 FR 
37797, June 25, 2012) (``AD 2012-12-12''), for all Airbus Model A330-
200 series airplanes, Model A330-200 Freighter series airplanes, Model 
A330-300 series airplanes, Model A340-200 series airplanes, and Model 
A340-300 series airplanes. AD 2012-12-12 was prompted by reports of 
sheared fasteners located on the outside skin of the forward cargo door 
and cracks on the frame fork ends, as well as cracks of the aft cargo 
door frame 64A. AD 2012-12-12 requires a detailed inspection of the 
outer skin rivets at the frame fork ends of the forward and aft cargo 
doors for sheared, loose, and missing rivets; repair of the outer skin 
rivets if necessary; and other repetitive inspections. We issued AD 
2012-12-12 to detect and correct sheared, loose, or missing fasteners 
on the forward and aft cargo door frame, which could result in the loss 
of structural integrity of the forward and aft cargo door.
    On August 9, 2013, we issued AD 2013-16-26, Amendment 39-17564 (78 
FR 53640, August 30, 2013) (``2013-16-26''), for all Airbus Model A330-
200 Freighter series airplanes, Model A330-200 and -300 series 
airplanes, and Model A340-200 and -300 series airplanes. AD 2013-16-26 
was prompted by reports of cracked adjacent frame forks of a forward 
cargo door. AD 2013-16-26 requires repetitive detailed inspections for 
cracks and sheared, loose, or missing rivets of the forward cargo door 
and, for certain airplanes, of the aft cargo door, and repair if 
necessary. We issued AD 2013-16-26 to detect and correct cracked or 
ruptured cargo door frames, which could result in

[[Page 37361]]

reduced structural integrity of the forward or aft cargo door.
    Since we issued AD 2012-12-12 and AD 2013-16-26, we have determined 
that a new inspection procedure is necessary to address the unsafe 
condition. In addition, the manufacturer has released some terminating 
action modifications for the cargo door structure, and provided 
procedures that allow postponing the structural reinforcement 
modification, which terminate the repetitive inspections.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0188, dated September 21, 2016; corrected September 22, 2016 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''); to correct an unsafe condition for 
certain Airbus Model A330-200 and -300 series airplanes; Model A330-200 
Freighter series airplanes; and Model A340-200, -300, -500, and -600 
series airplanes. The MCAI states:

    Several cases of cracked forward (FWD) and aft (AFT) cargo door 
frames, as well as loose, lost, or sheared rivets, have been 
reported by operators. Investigation showed that these findings are 
due to the low margins with respect to fatigue requirements for the 
AFT/FWD cargo door internal structure. Further analysis determined 
that the cargo door hook adjustment is a contributing factor to this 
issue. In case of a cracked or ruptured (FWD or AFT) cargo door 
frame, the loads will be transferred to the remaining structural 
elements. However, the secondary load path is able to sustain those 
loads only for a limited number of flight cycles (FC).
    This condition, if not detected and corrected, could lead to 
rupture of adjacent vertical frames and consequent reduced 
structural integrity of the FWD or AFT cargo door, possibly 
resulting in a cargo door failure, decompression of the aeroplane 
and injury to occupants.
    To initially address this potential unsafe condition, Airbus 
issued Service Bulletin (SB) A330-52-3043 and SB A340-52-4053 and, 
consequently, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation 
Civile] France issued AD 2001-124(B) and AD 2001-126(B), requiring a 
special detailed inspection of A330 and A340 AFT cargo doors. Since 
those [DGAC] ADs were issued, prompted by new occurrences, Airbus 
issued Alert Operators Transmission (AOT) A330-52A3085, AOT A340-
52A4092, AOT A330-52A3084, AOT A340-52A4091, AOT A330-A52L003-12, 
AOT 340-A52L004-12, AOT A330-A52L001-12 and AOT A340-A52L002-12, 
providing instructions to inspect the affected areas of both FWD and 
AFT cargo doors.
    Consequently, EASA issued AD 2011-0007 (later revised) [which 
corresponds to FAA AD 2012-12-12], and AD 2012-0274 [which 
corresponds to FAA AD 2013-16-26], to require repetitive detailed 
visual inspections of AFT and FWD cargo doors at specific frames and 
outer skin at all frame fork ends. Since these EASA ADs were issued, 
Airbus published SB A330-52-3087, SB A330-52-3095, SB A340-52-4095, 
SB A340-52-4101, SB A340-52-5020 and SB A340-52-5023, which took 
over the instructions of the above mentioned AOTs, and introduced 
revised thresholds and intervals. In addition, the inspection 
program was expanded to A340-500/-600 aeroplanes. Taking into 
account experience from inspections accomplished in accordance with 
the applicable Airbus SBs at original issue (listed above), Airbus 
issued Revision 01 of these SBs.
    Consequently, EASA issued AD 2015-0192, which superseded EASA AD 
2011-0007R1 and EASA AD 2012-0274, to require for each FWD and AFT 
cargo door, a one-time inspection/adjustment of the hook gaps ``U'' 
and ``V'', repetitive detailed inspections (DET) of all frame fork 
areas, frame head areas and outer skin areas to detect cracks or 
loose/sheared/missing fasteners, and, depending on findings, 
accomplishment of applicable corrective action(s). In addition, EASA 
AD 2015-0192 expanded the Applicability to Airbus A340-500/-600 
aeroplanes.
    Since EASA AD 2015-0192 was issued, Airbus published Revision 02 
of the inspection SBs, introducing high-frequency eddy-current 
inspection method for the frame forks structure. Airbus also 
determined that the interval for these repetitive inspections could 
be increased. In addition, Airbus released some modifications (mod) 
introducing reinforcements to the cargo door structure improving the 
fatigue characteristics. These modifications and associated SBs 
constitute terminating action for the required repetitive 
inspections. Furthermore, Airbus also published other SBs, 
introducing cold working after oversizing of the fastener holes as a 
means for structural reinforcement. Accomplishment of these SBs 
allows postponement of the required Point of Embodiment (Structural 
Modification Point) for the structural reinforcement modification 
SBs which terminate the repetitive inspection requirement.
    For the reasons described above, this [EASA] AD partially 
retains the requirements of EASA AD 2015-0192, which is superseded, 
and requires for each FWD and AFT cargo door initial and repetitive 
special detailed inspections (SDI) of all frame fork areas and 
detailed inspections (DET) of frame head areas and outer skin areas, 
and a one-time inspection/adjustment of the hook gaps ``U'' and 
``V'' and, depending on findings, the accomplishment of applicable 
corrective action(s). Additionally, this [EASA] AD requires 
reinforcement of the cargo door frame structure, while 
accomplishment of a cold working modification allows to defer the 
reinforcement of the cargo door structure.
    It should be noted that additional inspections exist for the 
cargo doors, as specified in Airbus A330 ALS [Airworthiness 
Limitation Section] Part 2 task 523211-02-01 and task 523211-02-02, 
and in Airbus A340 ALS Part 2 Task 523211-02-01.
    This [EASA] AD is re-published to correct typographical errors 
when referencing Airbus SB A340-52-4118.

    Related investigative actions include detailed inspections and high 
frequency non-destructive test inspections. Corrective actions include 
reaming holes, bushing holes, replacing affected parts, and repairing 
cracks. Additional work includes a one-time inspection of the ``U'' and 
``V'' hook gaps, and if necessary, an adjustment of the hook gaps.

0713.

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 designs.

Costs of Compliance

    We estimate that this proposed AD affects 73 airplanes of U.S. 
registry.
    We estimate that it would take up to 888 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 up to 
$126,420 per product. Based on these figures, we estimate the cost of 
this proposed AD on U.S. operators to be up to $14,738,700, or up to 
$201,900 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

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.
