Federal Register Volume 83, Issue 200 (October 16, 2018)

We are superseding Airworthiness Directive (AD) 2006-07-26, which applied to all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 airplanes. AD 2006-07-26 required a one-time inspection to detect discrepancies (e.g., cracking, loose/sheared fasteners, distortion) on the left-hand and right-hand wings, of the outer wing box upper skin and upper rib feet, and repair if necessary. Since we issued AD 2006- 07-26, after initial findings had suggested the cracking was isolated to a few airplanes, we received reports of cracking in these same areas on other Model ATR42 airplanes. This AD requires repetitive inspections to detect discrepancies on the left-hand and right-hand wings, of the outer wing box upper skin and upper rib feet, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2006-07-26, 
which applied to all ATR-GIE Avions de Transport R[eacute]gional Model 
ATR42 airplanes. AD 2006-07-26 required a one-time inspection to detect 
discrepancies (e.g., cracking, loose/sheared fasteners, distortion) on 
the left-hand and right-hand wings, of the outer wing box upper skin 
and upper rib feet, and repair if necessary. Since we issued AD 2006-
07-26, after initial findings had suggested the cracking was isolated 
to a few airplanes, we received reports of cracking in these same areas 
on other Model ATR42 airplanes. This AD requires repetitive inspections 
to detect discrepancies on the left-hand and right-hand wings, of the 
outer wing box upper

[[Page 52144]]

skin and upper rib feet, and repair if necessary. We are issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective November 20, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 20, 
2018.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2006-07-26, Amendment 39-14553 (71 FR 18205, 
April 11, 2006) (``AD 2006-07-26''). AD 2006-07-26 applied to all ATR-
GIE Avions de Transport R[eacute]gional Model ATR42 airplanes. The NPRM 
published in the Federal Register on June 1, 2018 (83 FR 25419).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
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.

    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.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. The following presents the comment received on the 
NPRM and the FAA's response.

Request To Refer to Latest Service Information

    Empire Airlines stated that paragraphs (g) and (i) of the proposed 
AD refer to ATR Service Bulletin ATR42-57-0074, dated October 19, 2017. 
Empire Airlines also stated that service bulletin has been revised.
    We infer that Empire Airlines requested that the references in 
paragraphs (g) and (i) of this AD be revised to refer to ATR Service 
Bulletin ATR42-57-0074, Revision 01, dated January 8, 2018. We agree to 
refer to the latest revision of the service information since the 
changes introduced in this revision do not affect the AD requirements. 
We have revised paragraphs (g) and (i) of this AD accordingly. We have 
also added paragraph (k) to this AD to provide credit for accomplishing 
ATR Service Bulletin ATR42-57-0074, dated October 19, 2017.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this final rule with the change described previously and minor 
editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    ATR-GIE Avions de Transport R[eacute]gional has issued ATR Service 
Bulletin ATR42-57-0074, Revision 01, dated January 8, 2018. This 
service information describes procedures for inspecting the outer wing 
box upper skin and upper rib feet, on the left-hand and right-hand 
wings, for discrepancies. This service information is reasonably

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 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 and 
associated appliances to the Director of the System Oversight Division.

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;
    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.
