Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2013-20-11, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2013-20-11 required modifying the passenger emergency oxygen container assembly. This new AD expands the affected group of oxygen containers to include those labeled “DAe Systems.” This AD was prompted by a determination that the unsafe condition also affects oxygen containers labeled “DAe Systems.” We are issuing this AD to prevent a high temperature oxygen generator and mask from falling down and possibly resulting in an ignition source in the passenger compartment, injury to passengers, and reduced availability of supplemental oxygen.

DATES:

This AD is effective September 23, 2016.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 2, 2013 (78 FR 64162, October 28, 2013).

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2013-20-11, Amendment 39-17617 (78 FR 64162, October 28, 2013) (“AD 2013-20-11”). AD 2013-20-11 applied to all Model A318, A319, A320, and A321 series airplanes. The NPRM published in the Federal Register on January 20, 2016 (81 FR 3061) (“the NPRM”). The NPRM was prompted by a determination that the unsafe condition also affects oxygen containers labeled “DAe Systems.” The NPRM proposed to continue to require modifying the passenger emergency oxygen container assembly. The NPRM also proposed to expand the affected group of oxygen containers to include those labeled “DAe Systems.” We are issuing this AD to prevent a high temperature oxygen generator and mask from falling down and possibly resulting in an ignition source in the passenger compartment, injury to passengers, and reduced availability of supplemental oxygen.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2014-0207, 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:

It was determined that oxygen generators, installed on a specific batch of Type 1 (22 min) passenger emergency oxygen container assemblies, may become detached by extreme pulling of the mask tube at the end of oxygen supply. Investigations revealed that such detachment can be caused by the increase in temperature towards the end of the generator operation, which may weaken the plastic housing in the attachment area of the bracket.

This condition, if not corrected, could make the rivets slip through the plastic housing, causing a `hot' oxygen generator and mask to fall down, possibly resulting in injury to passengers.

To address this potential unsafe condition, EASA issued AD 2012-0055 (later revised) [which corresponds to FAA AD 2013-20-11, Amendment 39-17617 (78 FR 64162, October 28, 2013)] to require modification of the affected oxygen container assemblies. That [EASA] AD also prohibited installation of unmodified containers on any aeroplane as replacement parts.

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 2012-0055R1, 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-2015-8463.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM.

Costs of Compliance

We estimate that this AD affects 4 airplanes of U.S. registry.

The actions required by AD 2013-20-11 and retained in this AD take about 2 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 2013-20-11 is $170 per product.

We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $680, or $170 per product.

According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all available costs in our cost estimate.

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 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.
