AD 2015-25-10

We are superseding Airworthiness Directive (AD) 2011-24-05 for certain Airbus Model A330-201, -202, -203, -223, -243, -301, -302, - 303, -321, -322, -323, -341, -342, and -343 airplanes, and Model A340- 200 and -300 series airplanes. AD 2011-24-05 required repetitive inspections for cracking of the hole(s) of the horizontal flange of the keel beam, and repair if necessary. This new AD requires changing the inspection compliance times, and, for certain airplanes, adding a one- time ultrasonic inspection for cracking at a certain fastener hole. This new AD also provides optional terminating action for the repetitive inspections. This AD was prompted by a determination that the rototest inspection and applicable corrective actions of a certain fastener hole were inadvertently omitted from the requirements in AD 2011-24-05. We are issuing this AD to detect and correct cracking of the fastener holes, which could result in rupture of the keel beam, and consequent reduced structuralintegrity of the airplane.

Final rule.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2011-24-05, Amendment 39-16869 (76 FR 73496, November 29, 2011). AD 2011-24-05 applied to certain Airbus Model A330- 201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340-200 and -300 series airplanes. The NPRM published in the Federal Register on May 4, 2015 (80 FR 25249).
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0010R1, dated May 5, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, - 341, -342, and -343 airplanes; and Model A340-200 and -300 series airplanes. The MCAI states:

During A330and A340 aeroplanes fatigue tests, cracks were detected on the RH [right-hand] and LH [left-hand] sides between the crossing area of the keel beam fitting and the front spar of the Centre Wing Box (CWB).
This condition, if not detected and corrected, could lead to keel beam rupture which would affect the structural integrity of the area.
Prompted by this potential unsafe condition, EASA issued AD 2006-0315 [http://ad.easa.europa.eu/blob/easa_ad_2006_0315.pdf/AD_2006-0315] (later revised to R1) to require repetitive special detailed inspections (SDI) [rotating probe inspection for cracking] on the horizontal flange of the keel beam in the area of first fastener hole aft of Frame (FR) 40 in order to maintain the structural integrity of the aeroplane.
After that [EASA] AD was issued, EASA issued AD 2010-0024 [which corresponds to FAA AD 2011-24-05, Amendment 39-16869 (76 FR 73496, November 29, 2011)], retaining the inspection requirements of EASA AD 2006-0315R1 [http://ad.easa.europa.eu/blob/easa_ad_2006_0315R1.pdf/AD_2006-0315R1], which was superseded, extending the applicability to aeroplanes with Airbus Mod 49202 embodied, and reducing the inspection thresholds and intervals.
Since that [EASA] AD [2010-0024] was issued, a new fatigue and damage tolerance evaluation has been conducted by Airbus, which concluded that due to the aeroplane utilization, the current inspection threshold and intervals have to be modified.
In addition, it was determined that the rototest inspection of fastener hole Nr 6, necessary to ensure that no crack was left unrepaired at the time of fastener hole cold working, was inadvertently not included in

[[Page 1498]]

Revisions 01 and 02 of both Airbus Service Bulletin (SB) A330-57- 3098 and A340-57-4106.
Prompted by these findings, EASA issued AD 2014-0010 [http://ad.easa.europa.eu/blob/easa_ad_2014-0010.pdf/AD_2014-0010], retaining the requirements of EASA AD 2010-0024, which was superseded, and redefined the inspection thresholds and intervals [by reducing certain compliance times], and added a one-time ultrasonic inspection of fastener hold Nr 6 in the junction keel beam fitting at FR40 on both LH and RH side[s].
Following issuance of EASA AD 2014-0010, it was identified that there was a need for clarifications [of affected airplanes] * * *.

The compliance times vary depending on airplane utilization and configuration. The earliest compliance time for the initial rotating probe inspections is the later of (1) before 10,400 total flight cycles or 67,800 total flight hours, whichever occurs first; and (2) within 24 months or 14,590 flight cycles or 43,790 flight hours, whichever occurs first. The latest compliance time for the initial inspections is the later of (1) before 20,800 total flight cycles or 67,900 total flight hours, whichever occurs first; and (2) within 24 months or 21,180 flight cycles or 63,560 flight hours, whichever occurs first. The compliance times for the repetitiveintervals range between 7,800 flight cycles or 50,900 flight hours and 10,700 flight cycles or 35,200 flight hours. The compliance times for the one-time ultrasonic inspection are the latest of (1) 21,000 flight cycles or 60,600 flight hours and within 2,400 flight cycles or 24 months; or the latest of (2) 22,100 flight cycles and 64,400 flight hours, or within 1,300 flight cycles or 24 months.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 25249, May 4, 2015) or on the determination of the cost to the public.

Conclusion

We reviewed the available data 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 thatwas proposed in the NPRM (80 FR 25249, May 4, 2015) for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 25249, May 4, 2015).

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 35 airplanes of U.S. registry.
The actions that were required by AD 2011-24-05, Amendment 39-16869 (76 FR 73496, November 29, 2011), and retained in this AD take about 41 work-hours per product, at an average labor rate of $85 per work hour. Required parts cost about $191 per product. Based on these figures, the estimated cost of the actions that were required by AD 2011-24-05 is $3,676 per product.
We also estimate that it takes about 23 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 $68,425, or $1,955 per product.
We have received 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.
