Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2012-18-

12, for certain Airbus Model A318, A319, and A320 series airplanes. AD 2012-18-12 currently requires modifying the off-wing escape slide (OWS) enclosures on the left-hand (LH) side and right-hand (RH) side of the fuselage. Since we issued AD 2012-18-12, we have received reports that additional OWS part numbers have been affected. This proposed AD would retain the requirements of AD 2012-18-12 and expand the applicability to all Airbus Model A318, A319, and A320 series airplanes. We are proposing this AD to prevent off-wing exits on the LH and RH sides of the fuselage from becoming inoperative, which, during an emergency, could impair the safe evacuation of occupants, possibly resulting in personal injuries.

DATES: We must receive comments on this proposed AD by December 7, 2015.

Discussion

On August 31, 2012, we issued AD 2012-18-12, Amendment 39-17189 (77 FR 57003, September 17, 2012). AD 2012-18-12 requires actions intended to address an unsafe condition on certain Airbus Model A318, A319, and A320 series airplanes.

Since we issued AD 2012-18-12, Amendment 39-17189 (77 FR 57003, September 17, 2012), we received reports that additional OWS part numbers have been affected which requires expanding the applicability to all Airbus Model A318, A319, and A320 series airplanes.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0025R1, dated May 26, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition on all Airbus Model A318, A319, and A320 series airplanes. The MCAI states:

One operator reported a torn out aspirator during scheduled deployment (for on ground testing purposes) of the Left Hand (LH) off-wing escape slide (OWS). Investigation results revealed that the aspirator of the OWS system interfered with the extrusion lip of the OWS enclosure during the initial stage of the deployment sequence.

This condition, if not corrected, could lead to an off-wing exit, either LH or Right Hand (RH), becoming unserviceable, which, during an emergency situation, could impair the safe evacuation of occupants, possibly resulting in personal injuries.

To address this potential unsafe condition, Airbus issued Service Bulletin (SB) A320-25-1649 containing modification instructions for certain part number (P/N) OWS enclosures. Consequently, EASA issued EASA AD 2010-0210 (http://ad.easa.europa.eu/ad/2010-0210) which corresponds to FAA AD 2012-

18-12, Amendment 39-17189 (77 FR 57003, September 17, 2012) to require modification of the affected OWS enclosures.

Since that EASA AD was issued, several other OWS P/Ns have been identified as potentially impacted.

For the reason described above, this EASA AD retains the requirements of EASA AD 2010-0210, which is superseded, expands the Applicability to all A318, A319 and A320 aeroplanes, and expands the batch of affected P/Ns prohibited to be installed on an aeroplane.

For the reason described above, EASA issued AD 2014-0025, retaining the requirements of EASA AD 2010-0210, which was superseded, expanding the Applicability to all A318, A319 and A320 aeroplanes, and expanding the batch of affected P/Ns prohibited to be installed on an aeroplane. That EASA AD also retained the requirements of * * * an AD, which was superseded, which required modification of the OWS and its aspirator.

This EASA AD is revised to amend paragraphs (1) and (3) to restore the original applicability of DGAC France AD 2001-380 and EASA AD 2010-0210, respectively, and to correct paragraph (2) to give credit for certain production modifications that were equivalent for the in-service actions previously required by DGAC France AD 2001-380.

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-

4202.

Related Service Information Under 1 CFR Part 51

Airbus has issued the following service information.

Airbus Service Bulletin A320-25-1156, Revision 03, dated December 5, 2001. This service information describes procedures for modifying OWS enclosures having part numbers (P/N) D31865-101, D31865-

102, D31865-103, D31865-104, D31865-105, D31865-106, D31865-107, or D31865-108 of certain Airbus Model A319 and A320 series airplanes.

Airbus Service Bulletin A320-25-1265, Revision 01, dated December 5, 2001. This service information describes procedures for modifying and installing the OWS enclosure on the LH and RH sides of the fuselage on certain Airbus Model A319 and A320 series airplanes.

Airbus Service Bulletin A320-25-1649, dated February 16, 2010. This service information describes procedures for modifying and installing OWS enclosures having part numbers (P/N) D31865-109, D31865-

110, D31865-209, or D31865-210, on the LH and RH sides of the fuselage on certain Airbus Model A318, A319, and A320 series airplanes.

Air Cruisers has issued Service Bulletin A320 004-25-84, Revision 4, dated November 9, 2012. This service information describes procedures for modifying LH and RH OWS.

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 of this NPRM.

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

We estimate that this proposed AD affects 851 airplanes of U.S. registry.

The actions required by AD 2012-18-12, Amendment 39-17189 (77 FR 57003, September 17, 2012), and retained in this proposed AD take about 14 work-hours per product, at an average labor rate of $85 per work-

hour. Required parts cost $0 per product. Based on these figures, the estimated cost of the actions that are required by AD 2012-18-12 is $1,190 per product.

We also estimate that it would take about 48 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 $0 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $3,472,080, or $4,080 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 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

Page 64377

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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

The Proposed Amendment
