Download as PDF Federal Register / Vol. 83, No. 106 / Friday, June 1, 2018 / Proposed Rules 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 Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ daltland on DSKBBV9HB2PROD with PROPOSALS Dassault Aviation: Docket No. FAA–2018– 0496; Product Identifier 2018–NM–031– AD. (a) Comments Due Date We must receive comments by July 16, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Dassault Aviation Model FALCON 2000 and FALCON 2000EX airplanes, certificated in any category, all serial numbers equipped with any anti-ice VerDate Sep<11>2014 16:09 May 31, 2018 Jkt 244001 pipe having part number (P/N) F2MA724561A1 or P/N F2MA724561A2, except airplanes on which Dassault Modification (mod) M5000 or Dassault mod M5001 has been embodied in production. (d) Subject Air Transport Association (ATA) of America Code 30, Ice and Rain Protection. (e) Reason This AD was prompted by reports of metallic debris found in the wing slat piccolo tubes; investigation revealed that the debris originated from the flow guide of the ball joint of the wing anti-ice valve. We are issuing this AD to address restricted airflow of the piccolo tubes, leading to insufficient wing anti-ice capability and significant undetected ice accretion on the wing, which could result in loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Repetitive Inspections and Corrective Actions Within 25 months after the effective date of this AD: Perform a detailed inspection for discrepancies of the flow guide of the ball joint located downstream of the wing anti-ice valve, and do all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of Dassault Aviation Service Bulletin F2000–441, dated June 20, 2017; or Dassault Aviation Service Bulletin F2000EX– 413, dated July 10, 2017; as applicable. Repeat the detailed inspection thereafter at intervals not to exceed 25 months. Do all applicable corrective actions before further flight. (h) No Reporting Requirement Although the service information identified in paragraph (g) of this AD specifies to submit certain information to the manufacturer, this AD does not include that requirement. (i) Other FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Section, Transport Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2018–0494; Product Identifier 2017– NM–182–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We issued AD 2006–07–26, Amendment 39–14553 (71 FR 18205, April 11, 2006) (‘‘AD 2006–07–26’’) for all ATR–GIE Avions de Transport ´ Regional Model ATR42 airplanes. AD 2006–07–26 requires a one-time inspection to detect discrepancies (e.g., cracking, loose/sheared fasteners, distortion) of the upper skin and rib feet of the outer wing boxes, and repair if necessary. AD 2006–07–26 resulted from a report of cracking on the upper skin and ribs of the outer wing box on an in-service airplane. We issued AD 2006–07–26 to detect and correct discrepancies of the upper skin and rib feet of the outer wing boxes, which could result in reduced structural integrity of the airplane. Actions Since AD 2006–07–26 Was Issued Since we issued AD 2006–07–26, we have received additional reports of cracking on the upper skin and ribs of the outer wing box on other Model ATR42 airplanes. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017–0244, dated December 7, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all ATR–GIE ´ Avions de Transport Regional Model ATR42 airplanes. The MCAI states: Occurrence was reported of detecting cracks on the wing of one in-service ATR 42 aeroplane in 2004. The cracks were found on the upper feet of ribs and on the upper skin of the wing outer boxes. This condition, if not detected and corrected, could adversely affect the structural integrity of the aeroplane. To address this potential unsafe condition, ATR issued Service Bulletin (SB) ATR42–57– PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 0064 to provide inspection instructions and ´ ´ DGAC [Direction Generale de l’Aviation Civile] France issued [French] AD F–2004– 191 (EASA approval 2004–12117) [which corresponds to FAA AD 2006–07–26] to require, for aeroplanes having accumulated more than 4,000 flight cycles (FC), a one-time Detailed Visual Inspection (DVI) of outer wing box upper skin and upper rib feet, on the right hand (RH) and left hand (LH) sides, from rib 24 to rib 29. After that [French] AD was issued, based on inspection results (all aeroplanes inspected, no similar case found), it was determined that these cracks were an isolated case. More recently, three other cases were reported, indicating that this may not be an isolated case and that cracks could occur in this area of the wings on other ATR 42 aeroplanes. Consequently, ATR published SB ATR42–57–0074 (hereafter referred as ‘ATR SB’ in this [EASA] AD) to provide inspection instructions. For the reasons described above, this [EASA] AD supersedes DGAC France AD F– 2004–191 and requires repetitive DVI of the same wing areas and, depending on findings, accomplishment of a repair. This proposed AD would also require, after each inspection, reporting the inspection findings, both positive and negative, to ATR–GIE Avions de ´ Transport Regional. You may examine the MCAI in the AD docket on the internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0494. Related Service Information Under 1 CFR Part 51 ATR–GIE Avions de Transport ´ Regional has issued ATR Service Bulletin ATR42–57–0074, dated October 19, 2017. This service information describes procedures for inspecting the upper skin and rib feet of the outer wing boxes for discrepancies. 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 the same type design. E:\FR\FM\01JNP1.SGM 01JNP1 25421 Federal Register / Vol. 83, No. 106 / Friday, June 1, 2018 / Proposed Rules Costs of Compliance We estimate that this proposed AD affects 37 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Inspection ......... 6 work-hours × $85 per hour = $510 per inspection cycle. 1 work-hour × $85 per hour = $85 per inspection cycle. Reporting .......... We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. daltland on DSKBBV9HB2PROD with PROPOSALS 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 AD is 2120–0056. The paperwork cost associated with this AD 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.

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 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.

Airworthiness Directives; ATR-GIE Avions de Transport 
R[eacute]gional Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2006-07-
26, which applies to all ATR-GIE Avions de Transport R[eacute]gional 
Model ATR42 airplanes. AD 2006-07-26 requires a one-time inspection to 
detect discrepancies (e.g., cracking, loose/sheared fasteners, 
distortion) of the upper skin and rib feet of the outer wing boxes, and 
repair if necessary. Since we issued AD 2006-07-26, we have

[[Page 25420]]

received reports of cracking in these same areas on other Model ATR42 
airplanes. This proposed AD would require repetitive inspections to 
detect discrepancies of the upper skin and rib feet of the outer wing 
boxes, and repair if necessary. We are proposing this AD to address the 
unsafe condition on these products.

DATES: We must receive comments on this proposed AD by July 16, 2018.

Discussion

    We issued AD 2006-07-26, Amendment 39-14553 (71 FR 18205, April 11, 
2006) (``AD 2006-07-26'') for all ATR-GIE Avions de Transport 
R[eacute]gional Model ATR42 airplanes. AD 2006-07-26 requires a one-
time inspection to detect discrepancies (e.g., cracking, loose/sheared 
fasteners, distortion) of the upper skin and rib feet of the outer wing 
boxes, and repair if necessary. AD 2006-07-26 resulted from a report of 
cracking on the upper skin and ribs of the outer wing box on an in-
service airplane. We issued AD 2006-07-26 to detect and correct 
discrepancies of the upper skin and rib feet of the outer wing boxes, 
which could result in reduced structural integrity of the airplane.

Actions Since AD 2006-07-26 Was Issued

    Since we issued AD 2006-07-26, we have received additional reports 
of cracking on the upper skin and ribs of the outer wing box on other 
Model ATR42 airplanes.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0244, dated December 7, 2017 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all ATR-GIE Avions de 
Transport R[eacute]gional Model ATR42 airplanes. The MCAI states:

    Occurrence was reported of detecting cracks on the wing of one 
in-service ATR 42 aeroplane in 2004. The cracks were found on the 
upper feet of ribs and on the upper skin of the wing outer boxes.
    This condition, if not detected and corrected, could adversely 
affect the structural integrity of the aeroplane.
    To address this potential unsafe condition, ATR issued Service 
Bulletin (SB) ATR42-57-0064 to provide inspection instructions and 
DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] France 
issued [French] AD F-2004-191 (EASA approval 2004-12117) [which 
corresponds to FAA AD 2006-07-26] to require, for aeroplanes having 
accumulated more than 4,000 flight cycles (FC), a one-time Detailed 
Visual Inspection (DVI) of outer wing box upper skin and upper rib 
feet, on the right hand (RH) and left hand (LH) sides, from rib 24 
to rib 29. After that [French] AD was issued, based on inspection 
results (all aeroplanes inspected, no similar case found), it was 
determined that these cracks were an isolated case.
    More recently, three other cases were reported, indicating that 
this may not be an isolated case and that cracks could occur in this 
area of the wings on other ATR 42 aeroplanes. Consequently, ATR 
published SB ATR42-57-0074 (hereafter referred as `ATR SB' in this 
[EASA] AD) to provide inspection instructions.
    For the reasons described above, this [EASA] AD supersedes DGAC 
France AD F-2004-191 and requires repetitive DVI of the same wing 
areas and, depending on findings, accomplishment of a repair.

    This proposed AD would also require, after each inspection, 
reporting the inspection findings, both positive and negative, to ATR-
GIE Avions de Transport R[eacute]gional.
    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0494.

Related Service Information Under 1 CFR Part 51

    ATR-GIE Avions de Transport R[eacute]gional has issued ATR Service 
Bulletin ATR42-57-0074, dated October 19, 2017. This service 
information describes procedures for inspecting the upper skin and rib 
feet of the outer wing boxes for discrepancies. 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 the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 37 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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 AD is 2120-
0056. The paperwork cost associated with this AD 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 AD 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
