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

**AGENCY** 

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

**ACTION** 

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

**SUMMARY** 

### : We propose to supersede Airworthiness Directive (AD) 2009–06– 06 for all Airbus Model A310 and A300–600 series airplanes. AD 2009– 06–06 currently requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations and maintenance tasks for aging systems maintenance. Since we issued AD 2009–06–06, we have determined that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. We are proposing this AD to prevent reduced structural integrity and reduced control of these airplanes due to the failure of system components.

Discussion

On February 27, 2009, we issued AD 2009–06–06, Amendment 39–15842 (74 FR 12228, March 24, 2009). AD 2009– 06–06 requires actions intended to address an unsafe condition for all Airbus Model A310 and A300–600 series airplanes.

Since we issued AD 2009–06–06, Amendment 39–15842 (74 FR 12228, March 24, 2009), we have determined that more restrictive maintenance requirements and airworthiness limitations are necessary.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0075, dated March 20, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for Airbus Model A310–203, –204, –221, –222, –304, –322, –324, and –325 airplanes; A300 B4–601, B4–603, B4– 620, and B4–622 airplanes; A300 B4– 605R and B4–622R airplanes; A300 F4– 605R and F4–622R, and A300 C4–605R Variant F airplanes. The MCAI states:

The airworthiness limitations for Airbus aeroplanes are currently published in Airworthiness Limitations Section (ALS) documents.

The mandatory instructions and airworthiness limitations applicable to the Aging Systems Maintenance (ASM) are specified in Airbus A310 or A300–600 ALS Part 4 documents, which are approved by the European Aviation Safety Agency (EASA). EASA AD 2007–0092 [ http:// ad.easa.europa.eu/blob/easa

_ad

_2007

_ 0092.pdf/AD

_2007-0092 ] [which corresponds to FAA AD 2009–06–06, Amendment 39– 15842] was issued to require compliance to the requirements as specified in these documents.

The revision 02 of Airbus A310 and Airbus A300–600 ALS Part 4 documents introduces more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with the instructions of ALS Part 4 could result in an unsafe condition.

For the reasons described above, this new AD retains the requirements of EASA AD


## 17452 Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Proposed Rules

2007–0092, which is superseded, and requires the implementation of the new or more restrictive maintenance requirements and/or airworthiness limitations as specified in Airbus A310 ALS Part 4, Revision 02, or Airbus A300–600 ALS Parr 4, Revision 02, as applicable to aeroplane type/model.



### 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–2014–
0173.

Relevant Service Information

Airbus has issued A310 Airworthiness Limitations Section (ALS) Part 4—Ageing Systems Maintenance, Revision 02, dated November 30, 2012 (for Model A310 series airplanes); and A300–600 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated April 18, 2012 (for Model A300–600 series airplanes). The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. 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 156 airplanes of U.S. registry.

The ALS revision required by AD 2009–06–06, Amendment 39–15842 (74 FR 12228, March 24, 2009), and retainedin this proposed AD takes about 1 workhour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that were required by AD 2009– 06–06 is $85 per product.

We also estimate that it would take about 1 work-hour 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 $13,260, or $85 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, 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:

**14 CFR Part 39**

**[Docket No. FAA–2014–0175; Directorate Identifier 2014–NM–014–AD]** 

**RIN 2120–AA64**



### Airworthiness Directives; Bombardier, **Inc. Airplanes**

**AGENCY** 

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

**ACTION** 

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

**SUMMARY** 

### : We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by reports that elevator power control unit (PCU) shear pins may fail prematurely. This proposed AD would require repetitive replacement of the elevator PCU shear pins. We are proposing this AD to prevent PCU failure of elevator PCU sheer pins. If all pins fail on one elevator, the elevator surface would become inoperative, which could reduce the controllability of the airplane and could result in a loss of redundancy for flutter prevention.

**DATES** 

### : We must receive comments on this proposed AD by May 12, 2014.
