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 ATR42-500 and 
Model ATR72-212A airplanes. This proposed AD was prompted by a report 
indicating interference between a Type III Emergency Exit door and the 
surrounding passenger cabin furnishing during a production check. This 
proposed AD would require measuring the gap between the Type III 
Emergency Exit doors and certain overhead stowage compartment fittings; 
removing certain fittings from the overhead stowage compartments and 
measuring the gap between the Type III Emergency Exit doors and the 
overhead stowage compartment hooks, if necessary; and re-installing or 
repairing, as applicable, the Type III Emergency Exit doors. We are 
proposing this AD to detect and correct interference between a Type III 
Emergency Exit door and the overhead stowage compartment fitting 
installed on the rail; which could result in obstructed opening of a 
Type III Emergency Exit door during an emergency evacuation.

DATES: We must receive comments on this proposed AD by March 9, 2015.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0280, dated November 26, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for ATR-GIE Avions de 
Transport R[eacute]gional Model ATR42-500 and Model ATR72-212A 
airplanes. The MCAI states:

    Interference between a Type III Emergency Exit door opening and 
the surrounding passenger cabin furnishing was detected during a 
production check.
    Subsequent investigation identified an insufficient gap between 
the Emergency Exit door internal skin structure and the overhead 
stowage compartment fitting, installed on the rail, as a cause of 
the interference.
    This condition, if not detected and corrected, could prevent an 
unobstructed opening of both Type III Emergency Exit doors in case 
of emergency evacuation.
    For the reasons described above, this [EASA] AD requires a one-
time check [measurement] of the gap between the Type III Emergency 
Exit door internal skin and a relevant [overhead stowage 
compartment] fitting and, depending on findings, the accomplishment 
of applicable corrective action(s). This [EASA] AD is considered to 
be a temporary measure and further actions may follow.

    Required actions include an additional measurement of the gap 
between the internal skin and overhead stowage compartment hooks of 
both Type III Emergency Exits, if necessary. Corrective actions include 
re-installing the Type III Emergency Exit doors or contacting the 
manufacturer for repair instructions and doing the repair, as 
applicable. 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-2015-0077.

Related Service Information

    ATR-GIE Avions de Transport R[eacute]gional has issued the 
following service information, which, among other things, describes 
procedures for removing certain fittings from the overhead stowage 
compartments, measuring the gap between the Type III Emergency Exit 
doors and the overhead stowage compartment hooks, re-installing the 
Type III Emergency Exit doors, and contacting the manufacturer for 
repair information.
    <bullet> ATR Service Bulletin ATR42-25-0180, dated August 19, 2013.
    <bullet> ATR Service Bulletin ATR72-25-1141, dated August 19, 2013.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

[[Page 3532]]

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.

Costs of Compliance

    We estimate that this proposed AD affects 1 airplane of U.S. 
registry.
    We also estimate that it would take about 1 work-hour per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be or $85 per 
product.
    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour and require parts costing $0, for a cost of $85 
per product. We have no way of determining the number of aircraft that 
might need these actions.

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.

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.
