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 adopt a new airworthiness directive (AD) for 
certain ATR-GIE Avions de Transport R[eacute]gional Model ATR72-101, -
201, -102, -202, -211, -212, and -212A airplanes. This proposed AD was 
prompted by reports of airplane incidents and accidents that have 
occurred because of low-level fuel tank situations and fuel starvation 
that resulted in engine flameouts. This proposed AD would require 
installing a fuel quantity indicator (FQI) equipped with a locking 
adaptor on the electrical connector. We are proposing this AD to 
prevent an engine flame-out, which could result in reduced 
controllability of the airplane.

DATES: We must receive comments on this proposed AD by September 3, 
2013.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0047, dated March 4, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Large aeroplane incidents and accidents have occurred because of 
fuel tank low level situations, or because of fuel starvation, 
resulting in one or several engine(s) flame-out. The results of the 
investigation into an ATR 72 accident in August 2005 have shown that 
overruling standard operational procedures and maintenance practices 
have led to this kind of occurrence.

[[Page 42899]]

    Consequently, additional actions to help avoid maintenance 
errors, like installation of a wrong gauge or wrong indicator, need 
to be taken.
    Although it is recognised that the fuel (indicating) system of 
the ATR42/72 type design is compliant with the applicable 
requirements, the risk of other maintenance errors will be mitigated 
by making installation of an ATR 42 Fuel Quantity Indicator (FQI) on 
an ATR 72 aeroplane mechanically impossible through a specific 
design change on the ATR 72.
    For the reasons described above, this [EASA] AD requires 
modification of the ATR 72 FQI by installing a locking adaptor on 
the electrical connector.

We are proposing this AD to prevent an engine flame-out, which could 
result in reduced controllability of the airplane. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Avions de Transport R[eacute]gional has issued Service Bulletin 
ATR72-28-1026, dated February 26, 2013. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

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

    Based on the service information, we estimate that this proposed AD 
would affect about 25 products of U.S. registry. We also estimate that 
it would take about 2 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 about $3,882 per product. Where 
the service information lists required parts costs that are covered 
under warranty, we have assumed that there will be no charge for these 
parts. As we do not control warranty coverage for affected parties, 
some parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $101,300, or $4,052 per product.

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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
