**RIN 2120–AA64**



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

**AGENCY**

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

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are superseding Airworthiness Directive (AD) 2007–22– 10 for all Airbus Model A330–200, A330–300, A340–200, A340–300, A340– 500, and A340–600 series airplanes. AD 2007–22–10 required repetitiveinspections of the left-hand and righthand wing main landing gear (MLG) rib 6 aft bearing lugs (forward and aft) to detect any cracks on the two lugs, and replacement if necessary. Since we issued AD 2007–22–10, we have received reports of additional cracking of the MLG rib 6 aft bearing forward lug. This new AD expands the applicability and reduces certain compliance times. We are issuing this AD to detect and correct cracking of the MLG rib 6 aft bearing lugs, which could result in collapse of the MLG upon landing.

**DATES** 

### : This AD becomes effective March 25, 2015.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of March 25, 2015.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2007–22–10, Amendment 39–15246 (72 FR 61796, November 1, 2007; corrected November 16, 2007 (72 FR 64532)). AD 2007–22– 10 applied to all Airbus Model A330– 200, A330–300, A340–200, A340–300, A340–500, and A340–600 series airplanes. The NPRM published in the Federal Register on September 4, 2014 (79 FR 52585).

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2013–0271, dated November 14, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition. The MCAI states:

During Main Landing Gear (MLG) lubrication, a crack was visually found in the MLG rib 6 aft bearing forward lug on one A330 in-service aeroplane. The crack had extended through the entire thickness of the forward lug at approximately the 4 o’clock position (when looking forward). It has been determined that similar type of crack can develop on other aeroplane types that are listed in the Applicability paragraph. This condition, if not detected and corrected, could affect the structural integrity of the MLG attachment.

To address this situation, Airbus issued inspection Service Bulletins (SB) A330–57– 3096, A340–57–4104 and A340–57–5009 to instruct repetitive inspection of the gear rib lugs.

Prompted by these findings, EASA issued Emergency AD 2006–0364–E to require repetitive detailed visual inspections of the Left Hand (LH) and Right Hand (RH) wing MLG rib 6 aft bearing lugs. Later EASA issued AD 2007–0247R1–E, which superseded EAD 2006–0364–E, to: —Expand the applicability to all A330 and

A340 aeroplanes, because the interference fit bushes cannot be considered as a terminating action, owing to unknown root cause; and —Add a second parameter quoted in Flight

Hours (FH) to the inspection interval in order to reflect the aeroplane utilization in
service.

EASA AD 2007–0247R1–E was republished to correct a typographical error.

Since the first crack finding and issuance of the inspection SBs and related ADs, six further cracks have been reported.

For the reasons described above, this [EASA] AD, which supersedes EASA EAD 2007–0247 R1–E and retains its requirements, is issued to expand the applicability to the newly certified models A330–223F and A330–243F and to reduce the threshold further to the risk assessment of recent in-service experience.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comment received. The commenter, an anonymous individual, supported the NPRM (79 FR 52585, September 4, 2014).

Conclusion

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting this AD as proposed, except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (79 FR 52585, September 4, 2014) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 52585, September 4, 2014).


## 8512 Federal Register / Vol. 80, No. 32 / Wednesday, February 18, 2015 / Rules and Regulations

Related Service Information Under 1
CFR Part 51

We reviewed the following service bulletins:

• Airbus Service Bulletin A330–57– 3096, Revision 5, dated October 17,

2013.

• Airbus Service Bulletin A340–57– 4104, Revision 4, dated October 17,

2013.

• Airbus Service Bulletin A340–57– 5009, Revision 3, dated October 17,

2013.

The service information describes procedures for detailed inspections of the MLG rib 6 forward and aft lugs for cracking. This service information is reasonably available; see **ADDRESSES** 

### for ways to access this service information.
Costs of Compliance

We estimate that this AD affects 81 airplanes of U.S. registry.

We estimate that it will take about 2 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work hour. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $13,770, or $170 per product.

We have no definitive data that would enable us to provide a cost estimate 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.

(h) Corrective Action

If any cracking is found during any inspection required by paragraph (g) of this AD, before further flight, replace the cracked MLG support rib using a method approved by the Manager, International Branch, ANM– 116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Airbus’s EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature. Replacement of an MLG support rib does not terminate the repetitive inspections required by paragraph (g) of this AD.

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

**AGENCY**

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

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are superseding Airworthiness Directive (AD) 2012–09– 07 for certain Airbus Model A319–111, –112, and –132 airplanes; Model A320– 111, –211, –212, –214, and –232 airplanes; and Model A321–111, –211, –212, and –231 airplanes. AD 2012–09– 07 required an electrical bonding test between the gravity fill re-fuel adaptor and the top skin panels on the wings; and, if necessary, an inspection for corrosion of the component interface and adjacent area; and repairing the gravity fuel adaptor if necessary. This new AD adds airplanes to the applicability and requires inspecting those airplanes to determine if a repair was done, and doing the electrical bonding test and corrective action if necessary. This AD was prompted by a determination that more airplanes are
