**[Docket No. FAA–2015–3149; Directorate Identifier 2015–NM–014–AD]** 

**RIN 2120–AA64**

**Airworthiness Directives; Airbus Airplanes** 

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

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330–200, –200 Freighter, and –300 series airplanes; and all Airbus Model A340–200, –300, –500, and –600 series airplanes. This proposed AD was prompted by reports of premature aging of certain chemical oxygen generators in the passenger compartment that resulted in failure of the generators to activate. This proposed AD would require inspecting to determine if certain passenger chemical oxygen generators are installed, and replacement of affected generators. We are proposing this AD to prevent failure of the chemical oxygen generator to activate during an emergency situation, which could result in unavailability of oxygen and possible incapacitation of the occupants.

**DATES :**  We must receive comments on this proposed AD by October 15, 2015.

**ADDRESSES :**  You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

Discussion

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 (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) 1170242–XX, 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 must be 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


### 52420 Federal Register / Vol. 80, No. 168 / Monday, August 31, 2015 / Proposed Rules

oxygen generators manufactured after 2001, and requires their removal from service before exceeding 10 years since date of manufacture.

3149.

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. 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 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 these same type designs.
Costs of Compliance

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



### E STIMATED 

### COSTS

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 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, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):
