### Airworthiness Directives; Airbus **Airplanes**

**AGENCY** 

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Notice of proposed rulemaking (NPRM).

**SUMMARY** 

### : We propose to supersede Airworthiness Directive (AD) 2012–03– 04, for certain Airbus Model A310 series airplanes. AD 2012–03–04 currently requires, for certain airplanes, modifying the wire routing and installing additional protective sleeves. Since we issued AD 2012–03–04, we received reports of new interferences of newly routed wire bundle 2S. This proposed AD would continue to require the actions in AD 2012–03–04, and would require additional work for certain airplanes. We are proposing this AD to prevent short circuits leading to arcing, and possible fuel tank explosion.

Discussion

On January 26, 2012, we issued AD 2012–03–04, Amendment 39–16945 (77 FR 21397, April 10, 2012). AD 2012–03– 04 required actions intended to address an unsafe condition on certain Airbus Model A310 series airplanes.

Since we issued AD 2012–03–04, Amendment 39–16945 (77 FR 21397, April 10, 2012), we received reports of new interferences of newly routed wire bundle 2S.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0188, dated September 19, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI
states:

Within the scope of the Fuel System Safety Program (FSSP), analyses of the wire routing showed that the route 2S of the fuel electrical circuit in the Right Hand (RH) wing ensures insufficient segregation between fuel quantity indication wires and the 115 Volts Alternating Current (VAC) wires of route 2S which could, under certain conditions, lead to a short circuit and subsequent arcing, creating a potential ignition source in the fuel tank vapour space.

This condition, if not detected, could result in a fuel tank explosion and consequent loss of the aeroplane.

To address this potential unsafe condition, DGAC France issued [an] AD * * * to require improvements of the design as specified in Airbus Service Bulletin (SB) A310–28–2148 original issue or Revision 01. EASA AD 2007–0230 [( http:// ad.easa.europa.eu/blob/easa

_ ad

_2007

_ 0230

_ Superseded.pdf/AD

_2007-0230

_ 1 )], which superseded [a] DGAC France AD * * *, [which] required those same actions, plus additional work 1, as defined in Airbus SB A310–28–2148 Revision 02.

Since EASA AD 2007–0230 was issued, an operator reported the possibility of chafing between the new routing of the wire bundle 2S in the RH wing pylon area and the wire bundle of No. 2 engine generator. The modification of this zone was introduced by Airbus SB A310–28–2148 Revision 02 as additional work 1. Investigation results showed that, to avoid the risk of chafing, the affected wiring harnesses must be installed at a higher position to provide sufficient clearance with the newly routed wire bundle 2S conduit.

Airbus published Revision 03 of SB A310– 28–2148 to implement these changes as additional work 2. Subsequently, a new potential interference due to insufficient clearance was found, which prompted Airbus to issue SB A310–28–2148 Revision 04.

Prompted by these findings and actions, EASA issued AD 2011–0005 [( http:// ad.easa.europa.eu/blob/easa

_ ad

_ 2011

_ 0005

_ Superseded.pdf/AD

_2011-0005

_ 1 )], retaining the requirements of EASA AD 2007–0230, which was superseded, and required the additional work 2 as specified in Revisions 03 and 04 of Airbus SB A310–28–2148.

Since EASA AD 2011–0005 was issued, several operators of aeroplanes not having been modified in-service through Airbus SB A310–36–2015, or without having Airbus modification 07633 applied in production, reported to have embodied Airbus SB A310– 28–2148 at Revision 02 or Revision 03 on the aeroplane. However, the adequate instructions to avoid the new interferences were only introduced in Airbus SB A310–28– 2148 Revision 04.

For the reasons described above, this new [EASA] AD retains the requirements of EASA AD 2011–0005, which is superseded, and requires, for certain aeroplanes, the additional work 3 [segregating wire route 2S in the RH pylon area or modifying the wire routings] as defined in Airbus SB A310–28–


## 2392 Federal Register / Vol. 79, No. 9 / Tuesday, January 14, 2014 / Proposed Rules

2148 Revision 06. As SB A310–28–2148 Revision 07 was issued to clarify the additional work 1, 2 and 3 [segregating wire route 2S in the RH pylon area or modifying the wire routings] for aeroplanes that have previously embodied that SB at original issue, Revision 01 or Revision 02, this AD also clarifies the required additional work. 

### You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating it in Docket No. FAA–
2013–1072.

Relevant Service Information

Airbus has issued Mandatory Service Bulletin A310–28–2148, Revision 07, dated February 13, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. Change to AD 2012–03–04, Amendment 39–16945 (77 FR 21397, April 10, 2012)

This proposed AD would retain all requirements of AD 2012–03–04, Amendment 39–16945 (77 FR 21397, April 10, 2012). Since AD 2012–03–04 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph designators have changed in this proposed AD, as listed in the following table:

### Also, we have revised certain paragraphs of AD 2012–03–04, Amendment 39–16945 (77 FR 21397, April 10, 2012), by placing the required service information into sub-paragraphs in this proposed AD. 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 41 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:

### 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 proposed 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**

**BILLING CODE 4910–13–P**



### COMMODITY FUTURES TRADING **COMMISSION**

**17 CFR Part 150**

**RIN 3038–AD82**



### Aggregation of Provisions

**AGENCY** 

### : Commodity Futures Trading Commission.

**ACTION** 

### : Proposed rule; extension of comment period.

**SUMMARY** 

### : On November 15, 2013, the Commodity Futures Trading Commission (‘‘Commission’’) published in the Federal Register a notice of proposed rulemaking (the ‘‘Aggregation Proposal’’) to amend existing regulations setting out the Commission’s policy for aggregation under its position limits regime. On the same day that the Commission adopted the Aggregation Proposal, it also adopted a proposal to establish speculative position limits for the 28 exempt and agricultural commodity futures and options contracts and the physical commodity swaps that are economically equivalent to such contracts that previously had been covered by part 151 of its regulations (the ‘‘Position Limits Proposal’’). However, the Position Limits Proposal was not published in the Federal Register until December 12, 2013. Because the comment period for both proposals was 60 days after publication in the Federal Register, the comment period for the Position Limits Proposal runs to a later date than the comment period for the Aggregation Proposal. In order to provide interested parties with an opportunity to comment on the Aggregation Proposal for so long as the comment period on the Position Limits Proposal is open, the Commission is extending the comment period for the Aggregation Proposal so that it ends at the same time as the comment period for the Position Limits Proposal.

**DATES** 

### : The comment period for the Aggregation Proposal published November 15, 2013, at 78 FR 68946, is extended until February 10, 2014.
