**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A330–200, –200 Freighter, and –300 series airplanes; and all Airbus Model A340– 200, –300, –500, and –600 series airplanes. The NPRM published in the Federal Register on August 31, 2015 (80 FR 52419).

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015–0119, dated June 24, 2015, correction January 12, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A330– 200, –200 Freighter, and –300 series airplanes; and Model A340–200, –300, –500, and –600 series airplanes. The MCAI states:

Reports have been received indicating premature ageing of certain passenger chemical oxygen generators, Part Number (P/ N) 117042–XX (XX representing any numerical value), manufactured by B/E Aerospace. Some operators reported that when they tried to activate generators, some older units failed to activate. Given the number of failed units reported, all the generators manufactured in 1999, 2000, and 2001 were considered unreliable.

This condition, if not corrected, could lead to failure of the generator to activate and consequently not deliver oxygen during an emergency, possibly resulting in injury to aeroplane occupants.

To address this potential unsafe condition, Airbus issued Alert Operators Transmission (AOT) A35L007–14, making reference to B/ E Aerospace Service Information Letter (SIL) D1019–01 (currently at Revision 1) and B/E Aerospace Service Bulletin (SB) 117042–35– 001. Consequently, EASA issued AD 2014– 0277 to require identification and replacement of the affected oxygen generators.

Since EASA AD 2014–0277 was issued, and following new investigation results, EASA has decided to introduce a life limitation concerning all P/N 117042–XX chemical oxygen generators, manufactured by B/E Aerospace.

For the reason described above, this EASA AD retains the requirements of EASA AD 2014–0277, which is superseded, expands the scope of the AD to include chemical oxygen generators manufactured after 2001, and requires their removal from service before exceeding 10 years since date of manufacture.

This [EASA] AD was republished to correct a typographical error in the applicability.

You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/#!document Detail;D=FAA-2015-3149-0002.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM (80 FR 52419, August 31, 2015) and the FAA’s
response. Request To Remove Operator Identification

Airbus asked that we remove the operator identification from the chemical oxygen generator pictured in Figure 2 to paragraph (g) of the proposed AD (80 FR 52419, August 31, 2015). Airbus stated that Figure 2 to paragraph (g) should replicate Figure 2


### 12406 Federal Register / Vol. 81, No. 46 / Wednesday, March 9, 2016 / Rules and Regulations

in EASA AD 2015–0119, dated June 24, 2015, which was published with no signs or references to an operator.

We agree with the commenter for the reason provided. We have changed the oxygen generator picture in Figure 2 to paragraph (g) of this AD accordingly. Clarification of Oxygen Generators for Replacement

We have revised paragraph (i) in this AD to clarify the identity of the oxygen generators to be replaced.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (80 FR 52419, August 31, 2015) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 52419, August 31, 2015).

Related Service Information Under 1 CFR Part 51

Airbus has issued Alert Operators Transmission (AOT) A35L007–14, Revision 01, June 17, 2015; including Appendix A, Revision 01, dated June 17, 2015. B/E Aerospace has issued Service Bulletin 117042–35–001, dated December 10, 2014. The service information describes procedures for inspecting to determine if certain passenger chemical oxygen generators are installed, and replacing affected generators. 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. Costs of Compliance

We estimate that this AD affects 91 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED 

### COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Inspection .......... 1 work-hour × $85 per hour = $85. $0 .......................................... $85 ........................................ $7,735.

Replacement ..... 1 work hour × $85 per hour = $85. $1,000 per oxygen generator $1,085 per oxygen generator $98,735 for one oxygen generator.

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. Examining the AD Docket

**Airworthiness Directives; Airbus Airplanes** 

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

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A300 B4–600, B4–600R, and F4– 600R series airplanes, and A300 C4– 605R Variant F airplanes (collectively called Model A300–600 series airplanes); and Model A310 series airplanes. This AD was prompted by reports of cracked aluminum support struts of the trimmable horizontal stabilizer (THS) caused by stress corrosion. This AD requires inspections to identify the part number of each support strut, repetitive inspections for cracking of the THS support strut ends, installation of reinforcing clamps on strut ends, and replacement of support struts, if necessary. We are issuing this AD to detect and correct cracked THS support struts, which could lead to the rupture of all four support struts making the remaining structure unable to carry limit loads, which could result in loss of the THS and reduced control of the airplane.

**DATES :**  This AD becomes effective April 13, 2016.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 13, 2016.
