[FR Doc. 2017–21344 Filed 10–5–17; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2017–0902; Product Identifier 2016–NM–188–AD] RIN 2120–AA64 Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede Airworthiness Directive (AD) 2004–03– 07, which applies to certain Airbus Model A320–111, –211, –212, and –231 series airplanes. AD 2004–03–07 requires repetitive inspections for fatigue cracking around the fasteners attaching the pressure panel to the flexible bracket at frame (FR) 36, adjacent to the longitudinal beams on the left and right sides of the airplane; and repair as necessary. Since we issued AD 2004–03–07, additional cracking has been found under the longitudinal beams in locations outside of the inspection areas required by AD 2004– 03–07. This proposed AD would retain certain requirements of AD 2004–03–07, expand the applicability, and require an inspection of the fastener holes on the pressure panel between FR 35 and FR 36 under the longitudinal beam and modification or repair as applicable. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by November 20, 2017.

AD 2004–03–07 was prompted by fatigue tests which revealed cracking around the fasteners attaching the pressure panel to the flexible bracket at FR 36, adjacent to the longitudinal beams on the left and right sides of the airplane. Investigation revealed that the damage was caused by high loads in this area. AD 2004–03–07 requires repetitive inspections for fatigue cracking around the fasteners attaching the pressure panel to the flexible bracket at FR 36, adjacent to the longitudinal beams on the left and right sides of the airplane; and repair as necessary. AD 2004–03–07 also provides an optional terminating action for the repetitive inspections. We issued AD 2004–03–07 to detect and correct fatigue cracking around the fasteners attaching the pressure panel to the flexible bracket at the FR 36 adjacent to the longitudinal beams, which could result in reduced structural integrity and possible rapid decompression of the airplane. Since we issued AD 2004–03–07, additional cracks have been found under the longitudinal beams at locations that are not included in the inspection area required by AD 2004– 03–07. Fatigue and damage tolerance analyses were performed and the results indicated that all the holes in the pressure panel above the longitudinal beams have to be cold worked. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016–0206, dated October 13, 2016; corrected October 14, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe VerDate Sep<11>2014 17:27 Oct 05, 2017 Jkt 244001 condition for certain Airbus Model A318 and Model A319 series airplanes, Model A320–211, –212, –214, –231, –232, and –233 airplanes, and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. The MCAI states: During fatigue tests, cracks were found around the fasteners connecting the pressure panel with the flexible bracket at fuselage frame (FR) 36, adjacent to the longitudinal beams on left-hand (LH) and right-hand (RH) sides. This condition, if not detected and corrected, could impair the structural integrity of the aeroplane. To address this unsafe condition, DGAC ´ ´ [Direction Generale de l’Aviation Civile] France issued [French] AD 2000–531–155(B) [which corresponds with FAA AD 2004–03– 07] to require repetitive inspections of the longitudinal beams of the FR 36 pressure panel and, depending on findings, the accomplishment of a repair. Since that [French] AD was issued, additional cracks have been found under the beams, but in locations not covered by the required inspections. Fatigue and damage tolerance analyses were performed, the results of which indicated that all the holes in the pressure panel above all the longitudinal beams have to be cold worked. For the reasons described above, this [EASA] AD retains the requirements of DGAC France AD 2000–531–155(B), which is superseded, extends the applicability to all A320 family aeroplanes and requires [a special detailed inspection of the fastener holes on the pressure panel between FR35 and FR36 under the longitudinal beam and] modification [or repair] of all the affected holes. This [EASA] AD is republished to correct the number of the superseded DGAC AD. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0902. Related Service Information Under 1 CFR Part 51 Airbus has issued Service Bulletin A320–53–1264, Revision 01, dated July 4, 2016. The service information describes procedures for a special detailed inspection (rotating probe) for cracking of the fastener holes on the pressure panel between FR 35 and FR 36 under the longitudinal beam and repair of any crack. Airbus has also issued Service Bulletin A320–53–1240, Revision 01, dated April 4, 2016, which describes procedures for modifying the pressure panel above the left and right longitudinal beams, including related PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 investigative action (e.g., high frequency eddy current (rototest) inspection of all the removed fastener holes) and corrective actions (e.g., repair), by cold working the attachment holes under the longitudinal beam at FR 36 for airplanes on which no cracking was found. In addition, Airbus issued Service Bulletin A320–53–1263, Revision 01, dated February 29, 2016, which describes procedures for modifying the pressure panel above the left and right longitudinal beams, including related investigative actions (e.g., eddy current rotating probe inspection of the fastener holes) and corrective actions (e.g., repair), by adding a doubler and a filler, and cold expansion of the holes under the longitudinal beam at FR 36 for airplanes on which cracking was found. 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. 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 these same type designs. Differences Between This Proposed AD and the MCAI or Service Information The MCAI specifies that operators can calculate revised thresholds for Model A319 and A320 series airplanes with sharklets installed (Airbus Service Bulletin A320–57–1193). This proposed AD does not include those calculations because the calculations could result in different inspection thresholds for each individual airplane. However, under the provisions of paragraph (o)(1) of this AD, we will consider requests for approval of alternative compliance times. Costs of Compliance We estimate that this proposed AD affects 737 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\06OCP1.SGM 06OCP1 46731 Federal Register / Vol. 82, No. 193 / Friday, October 6, 2017 / Proposed Rules ESTIMATED COSTS Action Labor cost Inspection [Retained from AD 2004–03–07].

Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this NPRM is 2120–0056. The paperwork cost associated with this NPRM has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this NPRM is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES–200. asabaliauskas on DSKBBXCHB2PROD with PROPOSALS 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 VerDate Sep<11>2014 17:27 Oct 05, 2017 Jkt 244001 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. 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.

ACTION: Proposed policy and request for comment. AGENCY: As new technology facilitates the introduction of area navigation (RNAV) instrument approach procedures over the past decade, the number of procedures available in the National Airspace System has nearly doubled. The complexity and cost to the Federal Aviation Administration (FAA) of maintaining the instrument flight procedures inventory while expanding the new RNAV capability is not sustainable. The FAA is considering the cancellation of certain circling procedures (to include circling-only instrument approach procedures (IAPs) and circling minima charted on straightin IAPs). The FAA proposes specific criteria to guide the identification and selection of appropriate circling procedures that can be considered for cancellation. The circling procedures associated with this cancellation initiative would be selected from the criteria outlined below.

SUPPLEMENTARY INFORMATION: DATES: Authority for This Rulemaking Under 49 U.S.C. 40103(a), the Administrator has broad authority to regulate the safe and efficient use of the navigable airspace. The Administrator is also authorized to issue air traffic rules and regulations to govern the flight, navigation, protection, and identification of aircraft for the protections of persons and property on the ground and for the efficient use of the navigable airspace. 49 U.S.C. 40103(b). Under Section 44701(a)(5), the PO 00000 Frm 00023 Fmt 4702 Sfmt 4702 Administrator promotes safe flight of civil aircraft in air commerce by prescribing regulations and minimum standards for other practices, methods, and procedures necessary for safety in air commerce and national security. This action is within the scope of that authority. IAPs are promulgated by rulemaking procedures and are incorporated by reference pursuant to 5 U.S.C. 552(a) and 1 CFR part 51 into Title 14 of the Code of Federal Regulations; Part 97 (14 CFR part 97), Subpart C—TERPS Procedures. Background The National Airspace System (NAS) is currently in transition to a ‘‘NextGen NAS’’. During this transition, the FAA is managing the technology and procedures to support both the Legacy NAS as well as the NextGen NAS. Managing two versions of the NAS requires excess manpower, infrastructure, and information management which is costly and unsupportable in the longterm. To mitigate these costs, the FAA has a number of efforts underway to effectively transition from the legacy to the NextGen NAS. One area of focus for this transition is instrument flight procedures (IFPs). The FAA seeks to ensure an effective transition from ground-based IFPs to greater availability and use of satellite-based IFPs while maintaining NAS safety. In early 2015, the FAA requested the RTCA’s Tactical Operations Committee (TOC) with providing feedback and recommendations on criteria and processes for cancelling instrument flight procedures. Among the many recommendations provided by the TOC were criteria on how to identify circling procedures that would qualify as candidates for cancellation. As of the beginning of 2017, there are approximately 12,000 IAPs in publication, and there were nearly 10,600 circling lines of minima. Circling procedures account for approximately one-third of all lines of minima in the NAS. In its continued effort to right-size the NAS through optimization and elimination of redundant and unnecessary IAPs, the FAA proposes the following criteria to guide the identification and selection of appropriate circling procedures to be considered for cancellation. It should be noted that National Procedures Assessment (NPA) Instrument Flight Procedure (IFP) cancellation activities and associated criteria do not supersede similar activities being performed under the E:\FR\FM\06OCP1.SGM 06OCP1

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2004-03-
07, which applies to certain Airbus Model A320-111, -211, -212, and -
231 series airplanes. AD 2004-03-07 requires repetitive inspections for 
fatigue cracking around the fasteners attaching the pressure panel to 
the flexible bracket at frame (FR) 36, adjacent to the longitudinal 
beams on the left and right sides of the airplane; and repair as 
necessary. Since we issued AD 2004-03-07, additional cracking has been 
found under the longitudinal beams in locations outside of the 
inspection areas required by AD 2004-03-07. This proposed AD would 
retain certain requirements of AD 2004-03-07, expand the applicability, 
and require an inspection of the fastener holes on the pressure panel 
between FR 35 and FR 36 under the longitudinal beam and modification or 
repair as applicable. We are proposing this AD to address the unsafe 
condition on these products.

DATES: We must receive comments on this proposed AD by November 20, 
2017.

    On January 29, 2004, we issued AD 2004-03-07, Amendment 39-13451 
(69 FR 5907, February 9, 2004) (``AD 2004-03-07''), for certain Airbus 
Model A320-111, -211, -212, and -231 series airplanes. AD 2004-03-07 
was prompted by fatigue tests which revealed cracking around the 
fasteners attaching the pressure panel to the flexible bracket at FR 
36, adjacent to the longitudinal beams on the left and right sides of 
the airplane. Investigation revealed that the damage was caused by high 
loads in this area. AD 2004-03-07 requires repetitive inspections for 
fatigue cracking around the fasteners attaching the pressure panel to 
the flexible bracket at FR 36, adjacent to the longitudinal beams on 
the left and right sides of the airplane; and repair as necessary. AD 
2004-03-07 also provides an optional terminating action for the 
repetitive inspections. We issued AD 2004-03-07 to detect and correct 
fatigue cracking around the fasteners attaching the pressure panel to 
the flexible bracket at the FR 36 adjacent to the longitudinal beams, 
which could result in reduced structural integrity and possible rapid 
decompression of the airplane.
    Since we issued AD 2004-03-07, additional cracks have been found 
under the longitudinal beams at locations that are not included in the 
inspection area required by AD 2004-03-07. Fatigue and damage tolerance 
analyses were performed and the results indicated that all the holes in 
the pressure panel above the longitudinal beams have to be cold worked.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0206, dated October 13, 2016; corrected 
October 14, 2016 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus Model A318 and Model A319 series 
airplanes, Model A320-211, -212, -214, -231, -232, and -233 airplanes, 
and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 
airplanes. The MCAI states:

    During fatigue tests, cracks were found around the fasteners 
connecting the pressure panel with the flexible bracket at fuselage 
frame (FR) 36, adjacent to the longitudinal beams on left-hand (LH) 
and right-hand (RH) sides.
    This condition, if not detected and corrected, could impair the 
structural integrity of the aeroplane.
    To address this unsafe condition, DGAC [Direction 
G[eacute]n[eacute]rale de l'Aviation Civile] France issued [French] 
AD 2000-531-155(B) [which corresponds with FAA AD 2004-03-07] to 
require repetitive inspections of the longitudinal beams of the FR 
36 pressure panel and, depending on findings, the accomplishment of 
a repair.
    Since that [French] AD was issued, additional cracks have been 
found under the beams, but in locations not covered by the required 
inspections. Fatigue and damage tolerance analyses were performed, 
the results of which indicated that all the holes in the pressure 
panel above all the longitudinal beams have to be cold worked.
    For the reasons described above, this [EASA] AD retains the 
requirements of DGAC France AD 2000-531-155(B), which is superseded, 
extends the applicability to all A320 family aeroplanes and requires 
[a special detailed inspection of the fastener holes on the pressure 
panel between FR35 and FR36 under the longitudinal beam and] 
modification [or repair] of all the affected holes.
    This [EASA] AD is republished to correct the number of the 
superseded DGAC AD.

0902.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-53-1264, Revision 01, dated 
July 4, 2016. The service information describes procedures for a 
special detailed inspection (rotating probe) for cracking of the 
fastener holes on the pressure panel between FR 35 and FR 36 under the 
longitudinal beam and repair of any crack.
    Airbus has also issued Service Bulletin A320-53-1240, Revision 01, 
dated April 4, 2016, which describes procedures for modifying the 
pressure panel above the left and right longitudinal beams, including 
related investigative action (e.g., high frequency eddy current 
(rototest) inspection of all the removed fastener holes) and corrective 
actions (e.g., repair), by cold working the attachment holes under the 
longitudinal beam at FR 36 for airplanes on which no cracking was 
found.
    In addition, Airbus issued Service Bulletin A320-53-1263, Revision 
01, dated February 29, 2016, which describes procedures for modifying 
the pressure panel above the left and right longitudinal beams, 
including related investigative actions (e.g., eddy current rotating 
probe inspection of the fastener holes) and corrective actions (e.g., 
repair), by adding a doubler and a filler, and cold expansion of the 
holes under the longitudinal beam at FR 36 for airplanes on which 
cracking was found.
    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.

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 these 
same type designs.

Differences Between This Proposed AD and the MCAI or Service 
Information

    The MCAI specifies that operators can calculate revised thresholds 
for Model A319 and A320 series airplanes with sharklets installed 
(Airbus Service Bulletin A320-57-1193). This proposed AD does not 
include those calculations because the calculations could result in 
different inspection thresholds for each individual airplane. However, 
under the provisions of paragraph (o)(1) of this AD, we will consider 
requests for approval of alternative compliance times.

Costs of Compliance

    We estimate that this proposed AD affects 737 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this NPRM is 2120-
0056. The paperwork cost associated with this NPRM has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this NPRM is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

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.

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
