Airworthiness Directives; Airbus SAS Airplanes

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

The FAA is superseding Airworthiness Directive (AD) 2002-07-05, which applied to all Airbus Model A300 B2, A300 B4, A300 B4-600, and A300 B4-600R series airplanes, and Model A300 F4-605R airplanes. AD 2002-07-05 required repetitive inspections for cracking of certain fittings, corrective action if necessary, and, for certain airplanes, a modification. This AD requires repetitive inspections for cracking of certain fittings, corrective actions if necessary, and, for certain airplanes, a modification; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that, for certain airplanes, the existing inspection compliance times were not sufficient to address the unsafe condition and needed to be reduced. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective September 19, 2019.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of September 19, 2019.

SUPPLEMENTARY INFORMATION:

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2002-07-05, Amendment 39-12699 (67 FR 16983, April 9, 2002; corrected April 23, 2002 (67 FR 19810)) (“AD 2002-07-05”). AD 2002-07-05 applied to all Airbus Model A300 B2, A300 B4, A300 B4-600, and A300 B4-600R series airplanes, and Model A300 F4-605R airplanes. The NPRM published in the Federal Register on May 9, 2019 (84 FR 20300). The NPRM was prompted by reports of cracked frame (FR) 40 aft fittings at stringer 33 on the left and right sides of the fuselage, and a determination that the existing inspection compliance times were not sufficient to address the unsafe condition and needed to be reduced. The NPRM proposed to require repetitive inspections for cracking of certain fittings, corrective actions if necessary, and, for certain airplanes, a modification. The FAA is issuing this AD to address propagation of cracks on the FR40 aft fittings due to local stress concentrations at the upper flange runout of FR40, which could result in reduced structural integrity of the airplane.

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0011R1, dated February 22, 2019 (“EASA AD 2019-0011R1”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Airbus SAS Model A300 series airplanes; Model A300 B4-600 series airplanes; Model A300 B4-600R series airplanes; and Model A300 C4-605R Variant F airplanes; and certain Model A300 F4-605R airplanes. The MCAI states:

After embodiment of Airbus SB [service bulletin] A300-53-0161, cracks were reported on three aeroplanes. Investigations highlighted that these cracks were caused by a local stress concentration at FR40 upper flange run-out, where the profile of the FR40 changes at the centre wing box connection.

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

Subsequently to this finding, Airbus established a High Frequency Eddy Current (HFEC) inspection program for A300 aeroplanes implemented in service through Airbus SB A300-53-0296. In the same time, Airbus launched mod. 10430 in production line associated to SB A300-53-6048 for the retrofit campaign for A300-600. The same HFEC inspection program was defined for A300-600 aeroplanes and included in SB A300-53-6048 instructions.

[Direction Generale de l'Aviation Civile] DGAC France AD F-1998-481-270 [which corresponds to FAA AD 2002-07-05] was published to mandate the embodiment of these two SBs.

DGAC France AD F-2000-038-032 was also published later to mandate Airbus SB A300-53-9017 applicable to A300-600ST aeroplanes.

Since DGAC France AD F-1998-481-270 and F-2000-038-032 were issued, material data used in the frame of fatigue and damage tolerance analysis has been changed. It was determined that the existing threshold and interval values must be reduced for A300-600 and A300-600ST fleet. Consequently, Airbus revised SB A300-53-6048 to Revision 05 and SB A300-53-9017 to Revision 02 to take into account the new thresholds and intervals.

For the reasons described above, this [EASA] AD retains the requirement of DGAC France AD F-1998-481-270R2 and F-2000-038-032R1, which are superseded, and introduces new thresholds and intervals for A300-600 and A300-600ST aeroplanes.

This [EASA] AD is revised to correct a typo in the Applicability, introduces Tables 1a and 1b, replacing original Table 1, to clarify inspection compliance times, and removes Note 1. This revised [EASA] AD also grants credit for actions accomplished using previous revisions of the applicable SB.

The MCAI added Model A300 C4-605R Variant F airplanes to its applicability because those airplanes are affected by the identified unsafe condition. Therefore, this AD also added Model A300 C4-605R Variant F airplanes to the applicability. Those airplanes were not on the U.S. type certificate data sheet at the time AD 2002-07-05 was issued. 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-2019-0319.

Comments

The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM.

Related IBR Material Under 1 CFR Part 51

EASA AD 2019-0011R1 describes procedures for modifying the profile of the FR40 aft fittings for certain airplanes, repetitive HFEC inspections for cracking of certain fittings, corrective actions for any cracking found, and reporting inspections findings.

This material 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

The FAA estimates that this AD affects 66 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

The FAA estimates that it would take about 1 work-hour per product to comply with the reporting requirement in this AD. The average labor rate is $85 per hour. Based on these figures, the FAA estimates the cost of reporting the inspection results on U.S. operators to be $5,610, or $85 per product.

The FAA has received no definitive data that would enable us to provide cost estimates for the on-condition action specified in this AD.

Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120-0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES-200.

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.

The FAA is 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.

This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.

Regulatory Findings

The FAA 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) Will not affect intrastate aviation in Alaska, and

(3) 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.
