2016-00379. Airworthiness Directives; Airbus Airplanes

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2004-20-14, for all Airbus Model A300 B4-2C, B4-103, and B4-203 airplanes; and all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes. AD 2004-20-14 required repetitive inspections to detect cracking of the splice fitting at fuselage frame (FR) 47 between stringers 24 and 26 (left- and right-hand sides), and corrective actions if necessary. This new AD reduces the inspection compliance time and repetitive inspection intervals, and adds Airbus Model A300 C4-605R Variant F airplanes to the applicability. This AD was prompted by a determination that the inspection compliance time and repetitive inspection interval must be reduced to allow timely detection of cracks in the splice fitting at fuselage FR 47. We are issuing this AD to detect and correct cracking of the splice fitting at fuselage FR 47; such cracking could result in reduced structural integrity of the airplane.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2004-20-14, Amendment 39-13819 (69 FR 60809, October 13, 2004), which superseded AD 2001-03-14, Amendment 39-12118 (66 FR 10957, February 21, 2001). AD 2004-20-14 applied to all Model A300 B4-600, B4-600R, and F4-600R (collectively called Model A300-600) series airplanes; and all Model A300 B4 series airplanes. The NPRM published in the Federal Register on May 14, 2015 (80 FR 27607). The NPRM was prompted by a determination that the inspection compliance time and repetitive inspection interval must be reduced to allow timely detection of cracks in the splice fitting at fuselage FR 47. The NPRM proposed to continue to require repetitive inspections to detect cracking of the splice fitting at fuselage FR 47 between stringers 24 and 26 (left- and right-hand sides), and corrective actions if necessary. The NPRM also proposed to reduce the inspection compliance time and repetitive inspection intervals, and add Model A300 C4-605R Variant F airplanes to the applicability. We are issuing this AD to detect and correct cracking of the splice fitting at fuselage FR 47; such cracking could result in reduced structural integrity of the airplane.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2013-0184R1, dated August 22, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Model A300 B4-600, B4-600R, and F4-600R (collectively called Model A300-600) series airplanes; all Model A300 B4 series airplanes; and all Model A300 C4-605R Variant F airplanes. The MCAI states:

In order to prevent crack development in the fastener holes at Frame (FR) 47 splicing joint on A300 aeroplanes, Airbus developed modification (Mod) 5890 for aeroplanes in production and issued corresponding Service Bulletin (SB) A300-53-0199 for aeroplanes in service.

Subsequently, cracks were found on FR47 splice fitting between stringers (STRG) 24 and 26 on A300 aeroplanes previously modified by SB A300-53-0199.

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

To address this potential unsafe condition, DGAC [Direction Générale de l'Aviation Civile] France issued AD 2002-184 http://ad.easa.europa.eu/​blob/​2002184tb_​superseded.pdf/​AD_​F-2002-184_​2 [which corresponds to FAA AD 2004-20-14, Amendment 39-13819 (69 FR 60809, October 13, 2004)], superseding [DGAC France] AD 85-152-069 and [DGAC France] AD 1999-515-298 [which corresponds to FAA AD 2001-03-14, Amendment 39-12118 (66 FR 10957, February 21, 2001)], to require repetitive High Frequency Eddy Current (HFEC) rotating probe inspections of the splice fitting between STRG 24 and 26 and, depending on findings, corrective action(s). DGAC France AD 2002-184(B) expanded the applicability to A300-600 aeroplanes, which have the same design.

Since that [DGAC France] AD was issued, a fleet survey and updated Fatigue and Damage Tolerance analyses have been performed in order to substantiate the second A300-600 Extended Service Goal (ESG2) exercise. The results of these analyses have determined that the inspection threshold and intervals for A300-600 aeroplanes must be reduced to allow timely detection of these cracks and the accomplishment of an applicable corrective action.

For the reasons described above, [EASA] AD 2013-0184 retains the requirements of DGAC France AD 2002-184, which is superseded, but requires accomplishment of the actions for A300-600 aeroplanes within the new thresholds and intervals introduced with Revision 05 of Airbus SB [service bulletin] A300-53-6123 [dated August 1, 2011].

This [EASA] AD was revised to correct the splices Part Numbers (P/N) in Table 4 of Appendix 1 of this [EASA] AD. Also, reference is now made to Airbus SB A300-53-6123 Revision 06 [dated September 28, 2011], which corrected this mistake compared to Revision 05.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/​#!documentDetail;​D=​FAA-2015-1417-0002.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 27607, May 14, 2015) and the FAA's response to each comment.

Request To Revise Compliance Times To Match Service Information

United Parcel Service (UPS) and FedEx Express requested that we revise the compliance times in paragraph (k) of the proposed AD (80 FR 27607, May 14, 2015) to match the compliance times in Airbus Service Bulletin A300-53-6123, Revision 06, dated September 28, 2011, and EASA AD 2013-0184R1, dated August 22, 2013.

We agree with the commenters' requests to revise the compliance times in paragraph (k) of this AD to reflect the compliance times in EASA AD 2013-0184R1, dated August 22, 2013. We have revised paragraph (k) of this AD accordingly. The changes extend the inspection interval and do not add an additional burden on operators.

Request To Retain Inspection Intervals in AD 2004-20-14, Amendment 39-13819 (69 FR 60809, October 13, 2004)

UPS requested that we revise paragraph (k) of the proposed AD (80 FR 27607, May 14, 2015) to retain the inspection intervals in AD 2004-20-14, Amendment 39-13819 (69 FR 60809, October 13, 2004), until the airplanes have reached their design service goal (DSG). UPS stated that acceleration of the inspection interval on airplanes that have less than 33 percent of the original DSG does not enhance safety. UPS explained that the proposed inspection interval reduction introduces additional opportunities for fastener hole damage due to the inspection process, thus increasing the risk for subsequent fatigue damage.

We disagree with the commenter's request. Since AD 2004-20-14, Amendment 39-13819 (69 FR 60809, October 13, 2004), was issued, Airbus conducted a fleet survey and an analysis to extend the DSG. In consideration of this information, we determined that the inspection interval and thresholds needed to be reduced to support timely detection of cracks. The Airbus analysis for the extension of the DSG and other data was used to determine the compliance thresholds and intervals for this AD. We have not changed this AD in this regard.

Request To Revise Repetitive Inspection Interval

FedEx Express requested that we revise the flight-cycle compliance time in paragraph (k)(1) of the proposed AD (80 FR 27607, May 14, 2015) from 2,000 flight cycles to 2,200 flight cycles so that the inspections can consistently be performed at the same interval as a C-check. FedEx Express stated that it considers the 2,200-flight-cycle interval to be conservative. FedEx Express submitted service experience from the previous inspections showing relatively few findings.

We do not agree with the commenter's request. The inspections are dependent upon various configurations and average flight times (AFTs). The commenter did not identify the applicable configuration for the requested 2,200-flight-cycle interval. Operators may request approval of a different interval under the provisions of paragraph (o)(1) of this AD if sufficient specific information is submitted to substantiate that the compliance time will provide an acceptable level of safety. We have not changed this AD in this regard.

Request To Remove Average Flight Time Classifications

UPS request that we revise the compliance times to remove the AFT classifications. UPS stated that it considers that the inspection interval difference with regard to the AFT adds a level of compliance complication that does not enhance fleet safety.

We disagree with the commenter's request. The compliance time thresholds and intervals using AFTs were developed by Airbus using fleet experience and analysis. Once we issue this AD, the commenter may request approval of a different interval under the provisions of paragraph (o)(1) of this AD. Sufficient data must be submitted to substantiate that the compliance time will provide an acceptable level of safety. We have not changed this AD in this regard.

Conclusion

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

• Are consistent with the intent that was proposed in the NPRM (80 FR 27607, May 14, 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 27607, May 14, 2015).

Related Service Information Under 1 CFR Part 51

Airbus has issued the following service information:

• Airbus Service Bulletin A300-53-0350, Revision 03, including Appendix 03, dated July 26, 2007. This service bulletin describes procedures for inspections to detect cracking of the splice fitting at fuselage FR 47 between stringers 24 and 26, and corrective actions.
• Airbus Service Bulletin A300-53-6123, Revision 06, dated September 28, 2011. This service bulletin describes procedures for inspections for cracking of the splice fitting at fuselage FR 47 between stringers 24 and 26, and corrective actions.

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 72 airplanes of U.S. registry.

We also estimate that it will take up to 14 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 $85,680, or $1,190 per product.

In addition, we estimate that any necessary follow-on actions will take up to 204 work-hours and require parts costing up to $37,000, for a cost of up to $54,340 per product. We have no way of determining the number of aircraft that might need these actions.

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.
