ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A320 series airplanes. That AD currently requires repetitive inspections to detect fatigue cracking in certain areas of the fuselage, and corrective action if necessary. That AD also provides for an optional terminating action for the repetitive inspections. This new AD reduces the compliance threshold and repetitive intervals for the inspections required by the existing AD. This AD is prompted by a full-scale fatigue survey on the Model A320 fleet. We are issuing this AD to detect and correct fatigue cracking of the fuselage, which could result in reduced structural integrity of the airplane. DATES: This AD becomes effective February 10, 2005. The incorporation by reference of Airbus Service Bulletin A320–53–1032, Revision 02, dated December 5, 2001, as listed in the AD, is approved by the Director of the Federal Register as of February 10, 2005. On February 12, 1999 (64 FR 1114, January 8, 1999), the Director of the Federal Register approved the incorporation by reference of Airbus Service Bulletin A320–53–1032, Revision 01, dated January 15, 1998.

Plain language information: Marcia Walters, marcia.walters@faa.gov. SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the Federal Aviation Regulations (14 CFR Part 39) with an AD to supersede AD 99–01–19, amendment 39–10987 (64 FR 1114, January 8, 1999). The existing AD applies to certain Airbus Model A320 series airplanes. The proposed AD was published in the Federal Register on August 5, 2004 (69 FR 47391), to require reducing the compliance threshold and repetitive intervals for the inspections required by the existing AD. The proposed AD would also continue to provide for an optional terminating action for the repetitive inspections. the preamble of the proposed AD, which differed from the AD requirements for the optional terminating action specified in paragraph (i) of the proposed AD. In the Summary, Relevant Service Information, and FAA’s Determination and Requirements of the proposed AD sections, we specify that the proposed AD would reduce the allowable time for the optional terminating action (provided by the existing AD). However, in paragraph (i) of the proposed AD we did not include that ‘‘allowable time’’ for accomplishing the optional terminating action. This decision was based on the fact that the French airworthiness directive referenced in the proposed AD did not specify an allowable time for the optional terminating action, and although the existing AD did contain an allowable time, it was not necessary to restate that time in the proposed AD. In light of the above, we have removed the wording ‘‘* * * would reduce the allowable time for the optional terminating action * * *’’ from the new actions in the Summary section. The Relevant Service Information and FAA’s Determination and Requirements of the proposed AD sections are not restated in the final rule. Comments Costs of Compliance This AD affects about 269 airplanes of U.S. registry. The inspection that is required by AD 99–01–19 and retained in this AD takes about 19 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the currently required inspection is $1,235 per airplane. The optional terminating action specified in Airbus Service Bulletin ADDRESSES: We provided the public the opportunity to participate in the development of this AD. We have considered the comment submitted on the proposed AD. The commenter supports the proposed AD. Clarification of Certain Wording in Preamble of Proposed AD For clarification, we are explaining an inadvertent error in certain wording in PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 Clarification of Paragraph (f)(2) of Proposed AD For clarification, we are explaining an inadvertent error in paragraph (f)(2) of the proposed AD. Paragraph (f)(2) of the proposed AD specified doing the inspection at the earlier of the times specified in paragraphs (f)(1)(i) and (f)(1)(ii) of the AD; the correct citation is paragraphs (f)(2)(i) and (f)(2)(ii) of the AD. Conclusion We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. E:\FR\FM\06JAR1.SGM 06JAR1 Federal Register / Vol. 70, No. 4 / Thursday, January 6, 2005 / Rules and Regulations A320–53–1031, if done, takes about 1 work hour per fastener hole, at an average labor rate of $65 per work hour. The cost of required parts is about $4,219 (for one modification kit). Based on these figures, the cost of the optional terminating action would be a minimum of $4,284 per airplane. Authority for This Rulemaking The FAA’s authority to issue rules regarding aviation safety is found in title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in subtitle VII, part A, subpart III, section 44701, ‘‘General requirements.’’ Under that section, the FAA is charged 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 AD. Regulatory Findings We have 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 DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD. See the ADDRESSES section for a location to examine the regulatory evaluation.

Pate, Flight Procedure Standards Branch (AMCAFS–420), Flight Technologies and Programs Division, Flight Standards Service, Federal Aviation Administration, Mike Monroney Aeronautical Center, 6500 South MacArthur Blvd. Oklahoma City, OK 73169 (Mail Address: P.O. Box 25082 Oklahoma City, OK 73125) telephone: (405) 954–4164. SUPPLEMENTARY INFORMATION: This amendment to part 97 of the Federal Aviation Regulations (14 CFR part 97) establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs). The complete regulatory description of each SIAP is contained in official FAA form documents which are incorporated by reference in this amendment under 5 U.S.C. 552(a), 1 CFR part 51, and § 97.20 of the Federal Aviation Regulations (FAR). The applicable FAA Forms are identified as FAA Forms 8260–3, 8260– 4, and 8260–5. Materials incorporated PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 by reference are available for examination or purchase as stated above. The large number of SIAPs, their complex nature, and the need for a special format make their verbatim publication in the Federal Register expensive and impractical. Further, airmen do not use the regulatory text of the SIAPs, but refer to their graphic depiction on charts printed by publishers of aeronautical materials. Thus, the advantages of incorporation by reference are realized and publication of the complete description of each SIAP contained in FAA form documents is unnecessary. The provisions of this amendment state the affected CFR (and FAR) sections, with the types and effective dates of the SIAPs. This amendment also identifies the airport, its location, the procedure identification and the amendment number. The Rule This amendment to part 97 is effective upon publication of each separate SIAP as contained in the transmittal. Some SIAP amendments may have been previously issued by the FAA in a National Flight Data Center (NFDC) Notice to Airmen (NOTAM) as an emergency action of immediate flight safety relating directly to published aeronautical charts. The circumstances which created the need for some SIAP amendments may require making them effective in less than 30 days. For the remaining SIAPs, an effective date at least 30 days after publication is provided. Further, the SIAPs contained in this amendment are based on the criteria contained in the U.S. Standard for Terminal Instrument Procedures (TERPS). In developing these SIAPs, the TERPS criteria were applied to the conditions existing or anticipated at the affected airports. Because of the close and immediate relationship between these SIAPs and safety in air commerce, I find that notice and public procedure before adopting these SIAPs are impracticable and contrary to the public interest and, where applicable, that good cause exists for making some SIAPs effective in less than 30 days. Conclusion The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore—(1) is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT E:\FR\FM\06JAR1.SGM 06JAR1

Amendment 39-13889; AD 2004-25-02]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A320 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain Airbus Model A320 series airplanes. That 
AD currently requires repetitive inspections to detect fatigue cracking 
in certain areas of the fuselage, and corrective action if necessary. 
That AD also provides for an optional terminating action for the 
repetitive inspections. This new AD reduces the compliance threshold 
and repetitive intervals for the inspections required by the existing 
AD. This AD is prompted by a full-scale fatigue survey on the Model 
A320 fleet. We are issuing this AD to detect and correct fatigue 
cracking of the fuselage, which could result in reduced structural 
integrity of the airplane.

DATES: This AD becomes effective February 10, 2005.
    The incorporation by reference of Airbus Service Bulletin A320-53-
1032, Revision 02, dated December 5, 2001, as listed in the AD, is 
approved by the Director of the Federal Register as of February 10, 
2005.
    On February 12, 1999 (64 FR 1114, January 8, 1999), the Director of 
the Federal Register approved the incorporation by reference of Airbus 
Service Bulletin A320-53-1032, Revision 01, dated January 15, 1998.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the 
Federal Aviation Regulations (14 CFR Part 39) with an AD to supersede 
AD 99-01-19, amendment 39-10987 (64 FR 1114, January 8, 1999). The 
existing AD applies to certain Airbus Model A320 series airplanes. The 
proposed AD was published in the Federal Register on August 5, 2004 (69 
FR 47391), to require reducing the compliance threshold and repetitive 
intervals for the inspections required by the existing AD. The proposed 
AD would also continue to provide for an optional terminating action 
for the repetitive inspections.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment submitted on the 
proposed AD. The commenter supports the proposed AD.

Clarification of Certain Wording in Preamble of Proposed AD

    For clarification, we are explaining an inadvertent error in 
certain wording in the preamble of the proposed AD, which differed from 
the AD requirements for the optional terminating action specified in 
paragraph (i) of the proposed AD. In the Summary, Relevant Service 
Information, and FAA's Determination and Requirements of the proposed 
AD sections, we specify that the proposed AD would reduce the allowable 
time for the optional terminating action (provided by the existing AD). 
However, in paragraph (i) of the proposed AD we did not include that 
``allowable time'' for accomplishing the optional terminating action. 
This decision was based on the fact that the French airworthiness 
directive referenced in the proposed AD did not specify an allowable 
time for the optional terminating action, and although the existing AD 
did contain an allowable time, it was not necessary to restate that 
time in the proposed AD. In light of the above, we have removed the 
wording ``* * * would reduce the allowable time for the optional 
terminating action * * *'' from the new actions in the Summary section. 
The Relevant Service Information and FAA's Determination and 
Requirements of the proposed AD sections are not restated in the final 
rule.

Clarification of Paragraph (f)(2) of Proposed AD

    For clarification, we are explaining an inadvertent error in 
paragraph (f)(2) of the proposed AD. Paragraph (f)(2) of the proposed 
AD specified doing the inspection at the earlier of the times specified 
in paragraphs (f)(1)(i) and (f)(1)(ii) of the AD; the correct citation 
is paragraphs (f)(2)(i) and (f)(2)(ii) of the AD.

Conclusion

    We have carefully reviewed the available data, including the 
comment that has been submitted, and determined that air safety and the 
public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    This AD affects about 269 airplanes of U.S. registry.
    The inspection that is required by AD 99-01-19 and retained in this 
AD takes about 19 work hours per airplane, at an average labor rate of 
$65 per work hour. Based on these figures, the estimated cost of the 
currently required inspection is $1,235 per airplane.
    The optional terminating action specified in Airbus Service 
Bulletin

[[Page 1185]]

A320-53-1031, if done, takes about 1 work hour per fastener hole, at an 
average labor rate of $65 per work hour. The cost of required parts is 
about $4,219 (for one modification kit). Based on these figures, the 
cost of the optional terminating action would be a minimum of $4,284 
per airplane.

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is 
found in title 49 of the United States Code. 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.
    This rulemaking is promulgated under the authority described in 
subtitle VII, part A, subpart III, section 44701, ``General 
requirements.'' Under that section, the FAA is charged 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 AD.

Regulatory Findings

    We have 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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); 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.

1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2004-25-02 Airbus: Amendment 39-13889. Docket No. FAA-2004-18773; 
Directorate Identifier 2002-NM-312-AD.

Effective Date

    (a) This AD becomes effective February 10, 2005.

Affected ADs

    (b) This AD supersedes AD 99-01-19, amendment 39-10987.

Applicability

    (c) This AD applies to Airbus Model A320-111, -211, -212, and -
231 series airplanes on which Airbus Modification 21346 has not been 
done, certificated in any category.

Unsafe Condition

    (d) This AD was prompted by a full-scale fatigue survey on the 
Model A320 fleet. We are issuing this AD to detect and correct 
fatigue cracking of the fuselage, which could result in reduced 
structural integrity of the airplane.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Repetitive Inspections

    (f) At the applicable time specified in paragraph (f)(1) or 
(f)(2) of this AD: Do a detailed inspection to find cracking on the 
outboard flanges around the fastener holes of frames 38 through 41, 
between stringers 12 and 21, using Airbus Service Bulletin A320-53-
1032, Revision 02, dated December 5, 2001. Accomplishment of the 
inspection required by this paragraph ends the requirements of AD 
99-01-19.
    (1) For airplanes on which the inspection specified in Airbus 
Service Bulletin A320-53-1032, Revision 01, dated January 15, 1998; 
or Revision 02, dated December 5, 2001; has been done as of the 
effective date of this AD: Do the next inspection within 4,900 
flight cycles after accomplishment of the last inspection, or within 
1,100 flight cycles after the effective date of this AD, whichever 
is later.
    (2) For airplanes on which no inspection specified in Airbus 
Service Bulletin A320-53-1032, Revision 01, dated January 15, 1998; 
or Revision 02, dated December 5, 2001; has been done as of the 
effective date of this AD: Do the inspection at the earlier of the 
times specified in paragraphs (f)(2)(i) and (f)(2)(ii) of this AD.
    (i) Before the accumulation of 30,000 total flight cycles.
    (ii) Before the accumulation of 24,800 total flight cycles, or 
within 3,500 flight cycles after the effective date of this AD, 
whichever is later.
    (g) If no crack is found during the inspection required by 
paragraph (f)(1) or (f)(2) of this AD: Repeat the inspection 
thereafter at intervals not to exceed 4,900 flight cycles.

    Note 1: For the purposes of this AD, a detailed inspection is 
defined as: ``An intensive visual examination of a specific 
structural area, system, installation, or assembly to detect damage, 
failure, or irregularity. Available lighting is normally 
supplemented with a direct source of good lighting at intensity 
deemed appropriate by the inspector. Inspection aids such as mirror, 
magnifying lenses, etc., may be used. Surface cleaning and elaborate 
access procedures may be required.''

Corrective Action

    (h) If any crack is found during any inspection required by 
paragraph (f) of this AD, before further flight, repair using Airbus 
Service Bulletin A320-53-1032, Revision 01, dated January 15, 1998; 
or Revision 02, dated December 5, 2001. Accomplishment of a repair 
using the service bulletin ends the repetitive inspection 
requirements for the area repaired. If any crack is found during any 
inspection required by this AD, and the service bulletin specifies 
to contact Airbus for appropriate action: Before further flight, 
repair using a method approved by the Manager, International Branch, 
ANM-116, FAA, Transport Airplane Directorate.

Optional Terminating Action

    (i) Accomplishment of Airbus Modification 21346 using Airbus 
Service Bulletin A320-53-1031, dated December 9, 1994; or Revision 
02, dated December 5, 2001; constitutes terminating action for the 
repetitive inspection requirements of this AD.
    (j) Accomplishment of the optional terminating action specified 
in AD 99-01-19 before the effective date of this AD, using Airbus 
Service Bulletin A320-53-1031, dated December 9, 1994; or Revision 
02, dated December 5, 2001; is considered acceptable for compliance 
with paragraph (i) of this AD.

Alternative Methods of Compliance (AMOCs)

    (k) The Manager, International Branch, ANM-116, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19.

Related Information

    (l) French airworthiness directive 2002-259(B), dated May 15, 
2002, also addresses the subject of this AD.
