Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.

SUMMARY:

We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM proposed to supersede AD 2011-14-06 and proposed revising the maintenance program. The NPRM was prompted by the determination that more restrictive limitations are necessary. This action revises the NPRM by revising the maintenance program to incorporate new limitations. We are proposing this AD to prevent fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

DATES:

We must receive comments on this proposed AD by July 14, 2014.

Discussion

We proposed to amend 14 CFR part 39 with an earlier NPRM for the specified products, which was published in the Federal Register on August 13, 2013 (78 FR 49213). The NPRM proposed to supersede AD 2011-14-06, Amendment 39-16741 (76 FR 42024, July 18, 2011), to require actions intended to address the unsafe condition for Airbus Model A318, A319, A320, and A321 series airplanes.

Since the NPRM (78 FR 49213, August 13, 2013) was issued, it has been determined that more restrictive limits are needed for damage tolerant airworthiness limitation items. This supplemental notice of proposed rulemaking (SNPRM) would require revising the maintenance program to incorporate new limitations.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2013-0147, dated July 16, 2013 (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:

The airworthiness limitations for Airbus A320 family aeroplanes are currently included in Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) document. The airworthiness limitations applicable to the Damage Tolerant Airworthiness Limitation Items (DT ALI) are currently given in Airbus ALS Part 2, which is approved by EASA.

Previously, EASA issued AD 2010-0071R1 [http://ad.easa.europa.eu/​blob/​easa_​ad_​2010_​0071_​R1.pdf/​AD_​2010-0071R1_​1] [associated with FAA AD 2011-14-06, Amendment 39-16741 (76 FR 42024, July 18, 2011)], which required the implementation of the DT ALI maintenance instructions as specified in Airbus A318/A319/A320/A321 ALI Document ref. AI/SE-M4/95A.0252/96 issue 10 and Airbus A319 Corporate Jet ALI Document ref. AI/SE-M2/95A.1038/99.

The new Airbus A318/A319/A320/A321 ALS Part 2 Revision 02, which includes also Airbus A319 Corporate Jet, introduces more restrictive DT ALI maintenance instructions. Failure to comply with these instructions could result in an unsafe condition.

Application of new DT ALI tasks 531129-02-2 and 531129-02-3 introduces initial and repetitive inspections of the windshield central lower node continuity fittings, replacing the one time inspection for that subject, previously required by EASA AD 2011-0231 [http://ad.easa.europa.eu/​blob/​easa_​ad_​2011_​0231.pdf] [associated with FAA AD 2013-13-03, Amendment 39-17491 (78 FR 41280, July 10, 2013)].

For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2010-0071R1 * * *, which are superseded, and requires compliance with all maintenance tasks as described in Airbus A318/A319/A320/A321 ALS part 2 at Revision 02.

The unsafe condition is fatigue cracking, accidental damage, or corrosion in principal structural elements and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane. 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-2013-0692.

Relevant Service Information

Airbus has issued A318/A319/A320/A321 ALS Part 2—Damage-Tolerant Airworthiness Limitation Items (DT ALI), Revision 02, dated May 28, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

Comments

We gave the public the opportunity to comment on the NPRM (78 FR 49213, August 13, 2013). The following presents the comments received on the NPRM and the FAA's response to each comment.

Request To Incorporate Airbus A318/A319/A320/A321 ALS Part 2, Revision 02, Dated May 28, 2013, in Paragraph (m) of the NPRM (78 FR 49213, August 13, 2013)

American Airlines (AAL) requested that we either delete the phrase “doing the actions required by paragraph (m) of this AD terminates the requirements of this paragraph,” from paragraph (i) of the NPRM (78 FR 49213, August 13, 2013), or incorporate Airbus A318/A319/A320/A321 ALS Part 2—Damage-Tolerant Airworthiness Limitation Items (DT ALI), Revision 02, dated May 28, 2013, in paragraph (m) of the NPRM. The commenter stated that paragraph (m) of the NPRM does not require incorporation of Airbus A318/A319/A320/A321 ALS Part 2, Revision 02, dated May 28, 2013; therefore, incorporating paragraph (m) would not Start Printed Page 30494fully terminate requirements of paragraph (i) of the NPRM.

We agree to revise the final rule by adding the incorporation of Airbus A318/A319/A320/A321 ALS Part 2—Damage-Tolerant Airworthiness Limitation Items (DT ALI), Revision 02, dated May 28, 2013, to paragraph (p) of this SNPRM.

Request To Incorporate Airbus A318/A319/A320/A321 ALS Part 3—Certification Maintenance Requirements (CMR), Revision 01, Dated June 15, 2012; in Paragraph (m) of the NPRM (78 FR 49213, August 13, 2013)

AAL requested that we incorporate Airbus ALS Part 3—CMR, Revision 01, dated June 15, 2012; in paragraph (m) of the NPRM (78 FR 49213, August 13, 2013).

We acknowledge that the latest approved CMR has been released; however, we disagree to revise this SNPRM. EASA has issued a separate AD 2013-0148, dated July 16, 2013 to require Airbus ALS Part 3—CMR, Revision 01, dated June 15, 2012. Therefore, we are considering separate rulemaking for mandating Airbus ALS Part 3—CMR, Revision 01, dated June 15, 2012. No change has been made to this SNPRM in this regard.

Request To Incorporate Airbus A318/A319/A320/A321 ALS Part 4—Ageing Systems Maintenance (ASM), Revision 01, Dated June 15, 2012 in Paragraph (m) of the NPRM (78 FR 49213, August 13, 2013)

Airbus and AAL requested that we revise paragraph (m) of the NPRM (78 FR 49213, August 13, 2013) to incorporate Airbus A318/A319/A320/A321 ALS Part 4—ASM, Revision 01, dated June 15, 2012. Airbus stated that the NPRM mentions Airbus A318/A319/A320/A321 ALS Part 4—ASM, dated January 8, 2008; however, Airbus A318/A319/A320/A321 ALS Part 4—ASM, Revision 01, dated June 15, 2012, introduces the extended service goal 1 (ESG1) exercise which allows continued operation of the A320-200 systems post-modification 39020 at a different compliance time.

We acknowledge that the latest approved ALS Part 4 has been released; however, we disagree to revise this SNPRM. EASA has issued EASA AD 2013-0146, dated July 16, 2013 to require Airbus A318/A319/A320/A321 ALS Part 4—ASM, Revision 01, dated June 15, 2012. Therefore, we might consider separate rulemaking for mandating Airbus A318/A319/A320/A321 ALS Part 4—ASM, Revision 01, dated June 15, 2012. No change has been made to this SNPRM in this regard.

Retained Paragraph of AD 2011-14-06, Amendment 39-16741 (76 FR 42024, July 18, 2011)

The NPRM (78 FR 49213, August 13, 2013) did not retain paragraph (h) of AD 2011-14-06, Amendment 39-16741 (76 FR 42024, July 18, 2011). We have retained that paragraph as paragraph (h) of this SNPRM and have re-designated the subsequent paragraphs accordingly.

Differences Between This Proposed AD and the MCAI or Service Information

The MCAI specifies that if there are findings from the ALS inspection tasks, corrective actions must be accomplished in accordance with Airbus maintenance documentation. However, this proposed AD does not include that requirement. Operators of U.S.-registered airplanes are required by general airworthiness and operational regulations to perform maintenance using methods that are acceptable to the FAA. We consider those methods to be adequate to address any corrective actions necessitated by the findings of ALS inspections required by 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.

Certain changes described above expand the scope of the NPRM (78 FR 49213, August 13, 2013). As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this proposed AD.

Costs of Compliance

We estimate that this proposed AD affects 851 airplanes of U.S. registry.

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

The actions that are required by AD 2011-14-06, Amendment 39-16741 (76 FR 42024, July 18, 2011), and retained in this proposed AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the required actions 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 $72,335, 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.
