2016-06247. Airworthiness Directives; Airbus Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede Airworthiness Directive (AD) 2014-13-12, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014-13-12 currently requires identifying the part number and serial number of each passenger oxygen container, replacing the oxygen generator manifold of any affected oxygen container with a serviceable manifold, and performing an operational check of the manual mask release, and doing corrective actions if necessary. Since we issued AD 2014-13-12, we have determined that affected containers have not only been marked with company name B/E Aerospace, as was specified, but also, for a brief period, with the former company name DAe Systems. This proposed AD would retain the requirements of AD 2014-13-12, and require replacing the oxygen generator manifold of any affected DAe oxygen container with a serviceable manifold. We are proposing this AD to detect and correct nonserviceable oxygen generator manifolds, which could reduce or block the oxygen supply and result in injury to passengers when oxygen supply is needed.

DATES:

We must receive comments on this proposed AD by May 5, 2016.

Discussion

On July 9, 2014, we issued AD 2014-13-12, Amendment 39-17888 (79 FR 45317, August 5, 2014) (“AD 2014-13-12”). AD 2014-13-12 requires actions intended to address an unsafe condition on all Airbus Model A318, A319, A320, and A321 series airplanes.

Since we issued AD 2014-13-12, we have determined that affected containers have not only been marked with company name B/E Aerospace, as was specified, but also, for a brief period, with the former company name DAe Systems.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0208, dated September 16, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition. The MCAI states:

During production of passenger oxygen containers, the manufacturer, B/E Aerospace, detected some silicon particles inside the oxygen generator manifolds. Investigation revealed that those particles (chips) had chafed from the mask hoses during installation onto the generator outlets. It was discovered that a defective mask hose installation device had caused the chafing.

This condition, if not detected and corrected, could reduce or block the oxygen supply, possibly resulting in injury to passengers when oxygen supply is needed.

To address this potential unsafe condition, EASA issued AD 2011-0167 [http://ad.easa.europa.eu/​blob/​easa_​ad_​2011_​0167_​superseded.pdf/​AD_​2011-0167_​1] to require the identification and modification of the affected oxygen container assemblies. That [EASA] AD also prohibited the installation of the affected containers on any aeroplane as replacement parts. It was subsequently established that Models A318-121 and A318-122 were missing from the Applicability of the [EASA] AD, and clarification was necessary regarding the affected containers.

Consequently, EASA issued AD 2012-0083 [http://ad.easa.europa.eu/​blob/​easa_​ad_​2012_​0083_​superseded.pdf/​AD_​2012-0083_​1] [which corresponds to FAA AD 2014-13-12, Amendment 39-17888 (79 FR 45317, August 5, 2014)], retaining the requirements of EASA AD 2011-0167, which was superseded, expanded the Applicability by adding two aeroplane models, and provided clarity by providing a list of affected passenger oxygen containers.

Since that [EASA] AD was issued, it was found that the affected containers have not only been marked with company name B/E Aerospace, as was specified, but also, for a brief period, with the former company name DAe Systems.

For the reason described above, this [EASA] AD retains the requirements of EASA AD 2012-0083, which is superseded, and expands the affected group of containers to include those that have the name “DAe Systems” on the identification plate.

This [EASA] AD also clearly separates the serial number (s/n) groups of containers into those manufactured by B/E Aerospace and those manufactured by DAe Systems, for which additional compliance time is provided.

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-2016-4228.

Related Service Information Under 1 CFR Part 51

Airbus has issued Service Bulletin A320-35A1047, dated March 29, 2011. The service information describes procedures for modifying the oxygen mask hoses of the Type 1 and Type 2 oxygen containers.

B/E AEROSPACE has issued Service Bulletins 1XCXX-0100-35-005 and 22CXX-0100-35-003, both Revision 2, both dated July 10, 2014. The service information describes procedures for replacement of the oxygen generator manifold.

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.

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 designs.

Changes to This Proposed AD

We have not included paragraph (h)(5) of AD 2014-13-12 in this proposed AD. Paragraph (h)(5) of AD 2014-13-12 inadvertently specified that certain actions were to be done if the affected part was listed in the specified service information. It should have specified that those actions were to be done only if the part was not listed in the service information. We have included the correct requirement in the new actions of this proposed AD.

We have removed Note 1 to paragraph (h)(1) of AD 2014-13-12, which identified affected passenger emergency oxygen container assemblies as those having the mark “B/E AEROSPACE” on the identification plate. This is no longer applicable because we have determined that affected containers have not only been marked with company name B/E Aerospace, as was specified, but also, for a brief period, with the former company name DAe Systems.

We have added Note 2 to figure 1 to paragraph (i)(7) of this AD, which provides information to clarify information presented in figure 1 to paragraph (i)(7) of this AD.

Costs of Compliance

We estimate that this proposed AD affects 22 airplanes of U.S. registry.

The actions required by AD 2014-13-12, and retained in this proposed AD take about 6 work-hours per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that are required by AD 2014-13-12 is $510 per product.

We also estimate that it would take about 6 work-hours 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 $11,220, or $510 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 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
