**Airworthiness Directives; Airbus Airplanes** 

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

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

**SUMMARY :**  We propose to supersede Airworthiness Directive (AD) 2004–19–
11 for certain Airbus Model 320 series airplanes. AD 2004–19–11 currently requires modification of the inner rear spar web of the wing, cold expansion of
the attachment holes of the forward pintle fitting and the actuating cylinder anchorage of the main landing gear (MLG), repetitive ultrasonic inspections for cracking of the rear spar of the wing, and corrective action if necessary. AD 2004–19–11 also provides optional terminating action for the repetitive inspections. Since we issued AD 2004– 19–11, we have determined that the terminating action is necessary to
address the unsafe condition. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would retain the requirements of AD 2004–19–11 and would require the previously optional terminating action. We are proposing this AD to prevent fatigue cracking of the inner rear spar, which may lead to reduced structural integrity of the wing and the MLG. **DATES :**  We must receive comments on this proposed AD by January 11, 2016.

**ADDRESSES :**  You may send comments by any of the following methods:

Discussion

On September 21, 2004, we issued AD 2004–19–11, Amendment 39–13805 (69 FR 58828, October 1, 2004). AD 2004– 19–11 requires actions intended to
address an unsafe condition on certain Airbus Model 320 series airplanes. AD 2004–19–11 superseded AD 2000–10– 15, Amendment 39–17739 (65 FR 34069, May 26, 2000).

Since we issued AD 2004–19–11, Amendment 39–13805 (69 FR 58828, October 1, 2004), we have determined
that the modification of the inner rear spar that is an optional terminating
action of AD 2004–19–11 must be accomplished in order to address the
identified unsafe condition.

As described in FAA Advisory Circular 120–104 (http://www.faa.gov/ documentLibrary/media/Advisory

_ Circular/120–104.pdf ), several programs have been developed to support
initiatives that will ensure the continued airworthiness of aging airplane structure. The last element of those initiatives is the requirement to establish a limit of validity (LOV) of the engineering data that support the structural maintenance program under 14 CFR 26.21. This proposed AD is the result of an assessment of the previously established programs by the design approval holder (DAH). The actions specified in this proposed AD are necessary to complete certain programs
to ensure the continued airworthiness of aging airplane structure and to support an airplane reaching its LOV.

The European Aviation Safety Agency, which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014–0169, corrected July 22, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct
an unsafe condition on certain Airbus Model A320 series airplanes. The MCAI

states:

During centre fuselage certification full scale fatigue test, cracks were found on the


### 74059 Federal Register / Vol. 80, No. 228 / Friday, November 27, 2015 / Proposed Rules

inner rear spar at holes position 52 on the right hand wing due to fatigue aspects.

This condition, if not detected and corrected, could affect the structural integrity of the aeroplane.

To prevent such cracks, Airbus developed modifications, which were introduced in production and in service through several Airbus Service Bulletins (SB). DGAC France issued * * * [an earlier AD], which was subsequently superseded by [DGAC] AD 2001–249 [which corresponds with FAA AD 2004–19–11, Amendment 39–13805 (69 FR 58828, October 1, 2004)], to require modification of the rear spar on some aeroplanes, post-modification repetitive inspections and, depending on findings, accomplishment of a repair. DGAC France AD 2001–249 also specified that modification
in accordance with Airbus SB A320–57–1089 (in-service equivalent to Airbus mod 24591) constituted (optional) terminating action for the repetitive inspections.

Since that [DGAC] AD [2001–249] was issued, in the framework of the A320 Extended Service Goal (ESG), it has been
determined that Airbus mod 24591 is necessary to allow aeroplanes to operate up
to the new ESG limit.

For the reasons described above, this [EASA] AD retains the requirements of DGAC France AD 2001–249, which is superseded, and requires modification of all pre-mod 24591 aeroplanes.

The modification includes modifying all specified fastener holes in the inner rear spar of the wing. You may examine
the MCAI in the AD docket on the

Internet at http://www.regulations.gov by searching for and locating Docket No.

Related Service Information Under 1 CFR part 51

Airbus has issued the following
service information.

• Airbus Service Bulletin A320–57– 1004, Revision 02, dated June 14, 1993.
This service information describes procedures for modifying the inner rear spar web of the wing.

• Airbus Service Bulletin A320–57– 1060, Revision 2, dated December 16,
1994. This service information describes procedures for a cold expansion of all
the attachment holes for the forward pintle fitting of the main landing gear (MLG), except for the holes that are for taper-lok bolts; and for a cold expansion of the holes at the actuating cylinder anchorage of the MLG.

• Airbus Mandatory Service Bulletin A320–57–1088, Revision 04, dated August 6, 2001. This service information describes procedures for doing ultrasonic inspections for cracking of the rear spar of the wing.

• Airbus Service Bulletin A320–57– 1089, Revision 03, dated February 9,
2001. This service information describes modification of the airplane by accomplishing cold reexpansion of the holes in the inner rear spar for the attachment of gear rib 5, forward pintle fitting, and actuating cylinder anchorage; and the installation of interference fit fasteners in the rear spar and gear rib 5.

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 the same type design.

Costs of Compliance

We estimate that this proposed AD affects 84 airplanes of U.S. registry.

The actions required by AD 2004–19– 11, Amendment 39–13805 (69 FR 58828, October 1, 2004), and retained inthis proposed AD take about 684 workhours per product, at an average labor rate of $85 per work-hour. Required parts cost about $13,644 per product. Based on these figures, the estimated cost of the actions that are required by AD 2004–19–11 is $71,784 per product.

We also estimate that it would take about 980 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $32,727 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $9,746,268, or $116,027 per product.

We have received no definitive data that would enable us to provide cost
estimates for the on-condition actions specified in 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 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.
