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

**AGENCY**

### : Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports of cracking of the aft fixed fairing (AFF) of the pylons due to fatigue damage of the structure. This AD requires repetitive inspections for damage and cracking of the AFF of the pylons, and repair if necessary. We are issuing this AD to detect and correct damage and cracking of the AFF of the pylons, which could result in detachment of a pylon and consequent reduced structural integrity of the airplane.

**DATES**

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM published in the Federal Register on November 30, 2015 (80 FR 74729) (‘‘the NPRM’’).

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014–0154, dated July 2, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Model A318, A319, A320, and A321 series airplanes. The MCAI states:

On aeroplanes equipped with post-mod 33844 CFM pylons, several operators have reported cracks on the Aft Fixed Fairing (AFF). After material analysis, it appears that


## 19483 Federal Register / Vol. 81, No. 65 / Tuesday, April 5, 2016 / Rules and Regulations

the pylon AFF structure, especially on this configuration, is subject to fatigue constraint damage which could lead to pylon AFF cracks.

Further to these findings, Airbus released Alert Operators Transmission (AOT) A54N002–12 which provides instructions to inspect the pylon AFF, applicable only to aeroplanes incorporating Airbus production mod 33844 on CFM pylons. More recently, Airbus issued Service Bulletin (SB) A320– 54–1027, superseding AOT A54N002–12.

This condition, if not detected and corrected, could lead to detachment of a pylon AFF from the aeroplane, possibly resulting in injuries to persons on the ground.

For the reasons described above, this [EASA] AD requires repetitive detailed inspections (DET) of the pylon AFF and, depending on findings, accomplishment of applicable corrective action(s).



### Since the MCAI was issued, EASA has clarified that the detachment of a pylon AFF from the airplane could result in damage to the airplane; such damage 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 Docket No. FAA–2015–

6537.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.
Explanation of Change to the Proposed Applicability

We have removed Airbus Model A320–215 airplanes from the Applicability statement of this AD; this model is not type certificated in the U.S.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD with the change described previously, including minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

Airbus has issued Service Bulletin A320–54–1027, dated April 10, 2014. This service information describes procedures for inspections for damage and cracking of the AFF of the pylons, and repair if necessary. 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. Costs of Compliance

We estimate that this AD affects 69 airplanes of U.S. registry.

We also estimate that it takes about 4 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $23,460, or $340 per product.

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this 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 AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD:

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.

### Amendment of Class D and Class E **Airspace; Wilmington, OH**

**AGENCY**

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

### : Final rule; correction.

**SUMMARY** 

### : This correction amends the final rule published in the Federal Register of February 8, 2016, amending the Class E surface area airspace and Class E airspace designated as an extension at Wilmington Air Park, Wilmington, OH. This correction adds part-time Notice to Airmen (NOTAM) language inadvertently removed to the Class E surface area description. The geographic coordinates and airport name of Wilmington Air Park in Class D and E airspace, and in Class E airspace extending upward from 700 feet above the surface are added to the rule. The Title is also amended to include Class D airspace.

**DATES** 

### : Effective 0901 UTC, April 5, 2016. The compliance date for this rule is March 31, 2016.

**SUPPLEMENTARY INFORMATION** 

### : History

The Federal Register published a final rule amending Class E airspace at Wilmington Air Park, Wilmington, OH, (81 FR 6450, February 8, 2016) Docket No. FAA–2015–7486. Subsequent to publication, the FAA found in amending the airport name and airport reference point for the airport, additional existing controlled airspace was inadvertently omitted from the rule. This action adds adjustment of the geographic coordinates in Class D airspace and Class E airspace extending upward from 700 feet or more above the surface of the Earth at Wilmington Air Park.

The FAA also determined that the part-time NOTAM language in the Class E surface area description was inadvertently removed in error. Potential safety concerns were identified due to the possibility for confusion in determining the operating rules and equipment requirements in the Wilmington Air Park terminal area. The concerns were based on the opportunity for part-time Class D surface area airspace and continuous Class E surface area airspace to be active at the same time.

To resolve these concerns, the FAA is keeping the part-time NOTAM language
