Airworthiness Directives; ATR-GIE Avions de Transport Reacutegional Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all ATR-GIE Avions de Transport Reacutegional Model ATR72 airplanes. This proposed AD was prompted by a determination that more restrictive maintenance instructions and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised maintenance instructions and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017-0223R1, dated December 15, 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 Reacutegional Model ATR72 airplanes. The MCAI states:

The airworthiness limitations and certification maintenance requirements (CMR) for ATR aeroplanes, which are approved by EASA, are currently defined and published in the ATR72-101/-201/-102/-202/

-211/-212/-212A Time Limits (TL) document. These instructions have been identified as mandatory actions for continued airworthiness.

Failure to accomplish these instructions could result in an unsafe condition.

Consequently, ATR published Revision 15 of the ATR72-101/-201/-

102/-202/-211/-212/-212A TL document, which contains new and/or more restrictive CMRs and airworthiness limitation tasks.

For the reasons described above, this EASA AD requires accomplishment of the actions specified in the ATR72-101/-201/-102/-

202/-211/-212/-212A TL document Revision 15, hereafter referred to as `the TLD' in this EASA AD.

This EASA AD, in conjunction with two other EASA ADs related to ATR42-200/-300/-320 (EASA AD 2017-0221) and ATR42-400/-500 (EASA AD 2017-0222) aeroplanes, retains the requirements of EASA AD 2009-

0241 and EASA AD 2012-0193. Once all these three ADs are effective, EASA will cancel EASA AD 2009-0242 and EASA AD 2012-0193.

This EASA AD is revised to provide the correct issue date (02 May 2017) of the TLD. The original EASA AD inadvertently referenced the EASA approval date for that document.

This NPRM would require revising the maintenance or inspection program to incorporate certain maintenance instructions and airworthiness limitations. The unsafe condition is fatigue cracking, damage, and corrosion in principal structural elements, which could result in reduced structural integrity of the airplane. 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-2018-0166.

Related Service Information Under 1 CFR Part 51

ATR-GIE Avions de Transport Reacutegional has issued the ATR72 Time Limits document, Revision 15, dated May 2, 2017. The service information describes preventive maintenance requirements and includes updated limitations, tasks, thresholds and intervals to be incorporated into the maintenance or inspection program. 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.

This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (k)(1) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure.

Similar to the MCAI, this proposed AD would not supersede AD 2000-

23-26, Amendment 39-11999 (65 FR 70775, November 28, 2000) (``AD 2000-

23-26''), or AD 2008-04-19 R1, Amendment 39-16069 (74 FR 56713, November 3, 2009) (``AD 2008-04-19 R1''). Rather, we have determined that a stand-alone AD would be more appropriate to address the changes in the MCAI. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate maintenance requirements and/or airworthiness limitations that are new or more restrictive than those required by AD 2000-23-26 and AD 2008-04-19 R1. Accomplishment of the proposed actions would then terminate all the requirements of AD 2000-23-26 and AD 2008-04-19 R1.

Costs of Compliance

We estimate that this proposed AD affects 26 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:

Estimated Costs

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

Cost per Cost on U.S.

Action Labor cost \1\ Parts cost product operators

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

Maintenance or inspection program 90 work-hours x $85 None................... $7,650 $198,900

revision. per hour = $7,650.

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

\1\ In the past, we have used 1 work-hour for revisions of the maintenance or inspection program. We have

determined that incorporating the entire airworthiness limitation document specified in this proposed AD would

take significantly longer than 1 work-hour.

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.

Page 12510

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.
