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 certain ATR-GIE Avions de Transport Reacutegional 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.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

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 Reacutegional 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 Reacutegional 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.

ATR Service Bulletin ATR42-25-0180, dated August 19, 2013.

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.

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.
