Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2004-23-

20 for certain Airbus Model A300 series airplanes and Model A300 B4-

601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, and C4-605R Variant F airplanes. AD 2004-23-20 currently requires, for certain airplanes, repetitive inspections for cracking around certain attachment holes, installation of new fasteners for certain airplanes, and follow-on corrective actions if necessary. AD 2004-23-20 also requires modifying certain fuselage frames, which terminates certain repetitive inspections. Since we issued AD 2004-23-

20, we received a report indicating that the material used to manufacture the upper frame feet was changed and negatively affected the fatigue life of the frame feet. This proposed AD would reduce the compliance times for the initial inspection and the inspection intervals. This proposed AD would also expand the applicability and require an additional repair on certain airplanes that have been modified. We are proposing this AD to prevent cracking of the center section of the fuselage, which could result in a ruptured frame foot and reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by March 17, 2016.

Discussion

On November 10, 2004, we issued AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004) for all Airbus Model A300 series airplanes and Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R and A300 C4-605R Variant F airplanes. (That AD superseded AD 2001-06-10, Amendment 39-12157 (66 FR 17490, April 2, 2001)). AD 2004-23-20 requires actions intended to address an unsafe condition on the products listed above.

Since we issued AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004) we received a report indicating that a change in material for manufacturing the frame feet for certain airplanes negatively impacted the fatigue life of the frame feet.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2013-0295, dated December 11, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for Airbus Model A300 B4-

601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, and A300 C4-605R Variant F airplanes. The MCAI states:

During a scheduled inspection of the fuselage frame feet of an in-service A300-600 aeroplane, cracks were observed in Frame (FR) 43, FR 44, FR 45 and FR 46 between stringer (STGR) 24 and STGR 30.

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

Page 5057

To address this unsafe condition, Direction Generale de l'Aviation Civile DGAC France issued an AD * * * to require repetitive inspections of the affected frames and stringers on both sides of the fuselage and, depending on findings, repairs, as specified in Airbus Service Bulletin (SB) A300-53-6122.

Subsequently, DGAC France issued AD F-2004-002 http://ad.easa.europa.eu/ad/F-2004-002 (EASA approval 2003-2108) which corresponds to FAA AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004), retaining the requirements of an AD * * * and required the embodiment of Airbus SB A300-53-6125 (Airbus modification 12168) in order to improve the life of the frame foot attachment.

Since DGAC France AD F-2004-002 was issued, a fleet survey and updated Fatigue and Damage Tolerance analyses were performed in order to substantiate the second A300-600 Extended Service Goal (ESG2) exercise.

It was highlighted that the frame feet material change from 2024T3511 (A300B4) to 7175T7351 (A300-600) had an impact on the frame feet fatigue life duration. Airbus SB A300-53-6122 was revised accordingly to decrease the inspection thresholds and intervals. Subsequent SB revision introduced a second structural modification point (SMP2) for aeroplanes that embody Airbus SB A300-53-6125 (modification 12168).

For the reasons described above, this new EASA AD retains the requirements of DGAC France AD F-2004-002, which is superseded, but requires those actions within the new thresholds and intervals as specified in Revision 04 of Airbus SB A300-53-6122.

The retained requirements include rototest inspections for cracking in the area surrounding the frame feet attachment holes between fuselage FR 41 and FR 46 from stringers 24 to 28 on the left and right sides, and related investigative and corrective action if necessary. The related investigative actions include additional rotating probe inspections of the adjacent holes. The corrective actions include reaming out cracks, cold working fastener holes, and installing oversized fasteners, or repair. This proposed AD also expands the applicability to include airplanes on which Airbus Modification 12168 was done. 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-2016-0451.

Related Service Information Under 1 CFR Part 51

Airbus has issued Service Bulletin A300-53-6122, Revision 04, dated February 27, 2012. The service information describes procedures for the repetitive inspections of certain frame feet attachment holes for cracks, installation of new fasteners, and repair of cracked areas.

In addition, Airbus has issued Service Bulletin A300-53-6125, Revision 01, dated June 13, 2003. The service information provides compliance times for certain airplanes to do the proposed modification.

Airbus has also issued Service Bulletin A300-53-6125, Revision 04, dated March 17, 2015. The service information describes procedures for the modification of certain upper frame feet fittings.

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.

FAA's Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.

Changes to AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004)

This proposed AD would retain all requirements of AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004). Since AD 2004-23-

20 was issued the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph designators have changed in this proposed AD, as listed in the following table:

Revised Paragraph Designators

------------------------------------------------------------------------

Requirement in AD 2004-23-20,

Amendment 39-13875 (69 FR 68779, Corresponding requirement in this

November 26, 2004) proposed AD

------------------------------------------------------------------------

paragraph (f) paragraph (g).

paragraph (g) paragraph (h).

paragraph (h) paragraph (i).

paragraph (i) paragraph (j).

paragraph (j) paragraph (k).

------------------------------------------------------------------------

We have converted ``TABLE 1.--SERVICE INFORMATION'' in AD 2004-23-

20, Amendment 39-13875 (69 FR 68779, November 26, 2004) to text in paragraphs (j)(3)(i) and (j)(3)(ii) of this proposed AD for formatting purposes only.

We have also moved the service information acceptable for compliance if previously done from ``TABLE 1.--SERVICE INFORMATION'' in AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004) to paragraph (r)(2) of this proposed AD.

Costs of Compliance

We estimate that this proposed AD affects 65 airplanes of U.S. registry.

The actions that are required by AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004), and retained in this proposed AD take about 90 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost about $4,000 per product. Based on these figures, the estimated cost of the actions that were required by AD 2004-23-20 is $11,650 per product.

We also estimate that it would take up to 109 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost up to $6,070 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $996,775, or $15,335 per product.

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national

Page 5058

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 this proposed regulation:

  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.

    (k) Retained Exceptions to Service Bulletin Procedures

    This paragraph restates the requirements of paragraph (j) of AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004), with specific delegation approval language. During any inspection required by paragraphs (g), (h), (i), or (j) of this AD, if the applicable service information specified in paragraphs (g), (h), (i), and (j) of this AD specifies to contact the manufacturer for appropriate instructions: Before further flight, perform all applicable corrective actions in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Direction Generale de l'Aviation Civile (DGAC) (or its delegated agent); or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA).

    (l) New Definition for This AD: Average Flight Time (AFT)

    For the purpose of this AD, use the parameters specified in paragraphs (l)(1), (l)(2), and (l)(3) of this AD to determine the applicable AFT for the actions required by paragraph (m) and compliance times required by paragraph (n) of this AD.

    (1) The initial inspection compliance time, as the total accumulated flight hours counted from take-off to touch-down, divided by the total accumulated flight cycles as of the effective date of this AD.

    (2) The first repetitive inspection interval, as the total accumulated flight hours divided by the total accumulated flight cycles at the time of the inspection.

    (3) The second inspection interval and subsequent, as the flight hours divided by the flight cycles between the last two inspections.

    (m) New Requirements of This AD: Inspections and Corrective Actions

    (1) At the applicable time specified in paragraph (n)(1) of this AD, do a rotating probe inspection for discrepancies of the frame feet attachment holes from FR 41 through FR 46, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-

    6122, Revision 04, dated February 27, 2012. Repeat the inspections thereafter at intervals not to exceed those specified in paragraph (n)(2) of this AD. Accomplishment of this inspection terminates the inspections required by paragraph (g)(2) of this AD.

    (2) If any discrepancy (e.g., cracking or damage) is found during any inspection required by paragraph (m)(1) of this AD, before further flight, do all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6122, Revision 04, dated February 27, 2012; except where Airbus Service Bulletin A300-

    53-6122, Revision 04, dated February 27, 2012, specifies to contact Airbus, before further flight, repair using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or EASA; or Airbus's EASA DOA.

    (3) Corrective actions, as required by paragraph (m)(2) of this AD, do not constitute terminating action for the repetitive inspections required by paragraph (m)(1) of this AD.

    (n) Compliance Times for Initial and Repetitive Inspections

    (1) Do the initial rotating probe inspection required by paragraph (m)(1) of this AD at the applicable times specified in paragraphs (n)(1)(i), (n)(1)(ii), and (n)(1)(iii) of this AD; or within 1,000 flight cycles after the effective date of this AD; whichever occurs later.
