AD 2018-01-11

We are adopting a new airworthiness directive (AD) for certain Airbus Model A319-115 and A319-133 airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. This AD was prompted by a fire during a flight, in the vicinity of the gaseous oxygen system (GOS) for passengers. We are issuing this AD to address the unsafe condition on these products.

Final rule; request for comments.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2014-0045, dated February 25, 2014; corrected March 4, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus Model A319-115 and A319-133 airplanes. The MCAI states:

Following an ECAM [electronic centralized aircraft monitor] warning ``CARGO SMOKE'' during flight, the flight crew elected to divert and the aeroplane made an uneventful landing. The post-flight inspection evidenced a heavy fire in the vicinity of the Gaseous Oxygen System (GOS) for passengers, located close to the cargo area. The origin of the fire has not been clearly identified. After more investigation, Airbus determined that the current optional passenger GOS design, specific to A319 aeroplanes, is not robust enough to prevent further events of this kind.
This condition, if not detected and corrected, could lead to an uncontrolled fire, possibly resulting in loss of the aeroplane.
To address this potential unsafe condition, Airbus developed mod 153555 to improve

[[Page 1528]]

the (optional) A319 GOS for passengers and published Service Bulletin (SB) A320-35-1062 to provide that modification for in- service application.
Consequently, EASA issued AD 2013-0153 to require modification of the passenger GOS installation.
Since that [EASA] AD was issued, a mistake was identified in Airbus SB A320-35-1062 concerning the pressure relief valve installation and the SB has been corrected and revised accordingly with mod 155860.
For the reason described above, this [EASA] AD retains the requirements of EASA AD 2013-0153, which is superseded, but requires those actions to be done in accordance with the instructions of Airbus SB 35-1062 Revision 01.
This [EASA] AD has been republished to correct an error that referenced the wrong effective date for EASA AD 2013-0153.

FAA's Determination and Requirements of This 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. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

FAA's Determination of the Effective Date

Since there are currently no domestic operators of this product, we find good cause that notice and opportunity for prior public comment are unnecessary. In addition, for the reason(s) stated above, we find that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2017-1244; Product Identifier 2013-NM-145-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Costs of Compliance

Currently, there are no affected U.S.-registered airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition, and doing the actions specified in those instructions. Based on the actions specified in the MCAI AD, we are providing the following cost estimates for an affected airplane that is placed on the U.S. Register in the future:

Estimated Costs --------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product -------------------------------------------------------------------------------------------------------------------------------------------------------- Passenger GOS modification........... Up to 33 work-hours x $85 per Up to $30,782........... Up to $33,587
hour = $2,805. Placard modification................. 5 work-hours x $85 per hour = $0...................... $425
$425. Pressure hose modification........... 8 work-hours x $85 per hour = $9,690.................. $10,370
$680. --------------------------------------------------------------------------------------------------------------------------------------------------------

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 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.
