14 CFR Part 39

[Docket No. FAA-2007-26856; Directorate Identifier 2006-NM-125-AD; 
Amendment 39-15082; AD 2007-12-04]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and 
F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes 
(Collectively Called A300-600 Series Airplanes)

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) that applies to all Airbus Model A300-600 series airplanes. That 
AD currently requires inspections of the lower door surrounding 
structure to detect cracks and corrosion; inspections to detect 
cracking of the holes of the corner doublers, the fail-safe ring, and 
the door frames of the door structures; and repair if necessary. That 
AD also provides for optional terminating action for certain 
inspections. This new AD retains all requirements of the existing AD, 
mandates the previously optional terminating action, reduces the 
applicability of the existing AD, and adds repetitive inspections 
behind scuff plates for certain affected airplanes. This AD results 
from a determination that further rulemaking is necessary to improve 
the fatigue behavior of the cabin door surroundings. We are issuing 
this AD to prevent corrosion between the scuff plates at exit and cargo 
doors and fatigue cracks originating from certain fastener holes 
located in adjacent structure, which could result in reduced structural 
integrity of the door surroundings.

DATES: This AD becomes effective July 10, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of July 10, 2007.
    On September 4, 1998 (63 FR 40812, July 31, 1998), the Director of 
the Federal Register approved the incorporation by reference of certain 
other publications listed in the AD.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 98-16-05, amendment 39-
10680 (63 FR 40812, July 31, 1998). The existing AD applies to all 
Airbus Model A300-600 series airplanes. That

[[Page 30962]]

NPRM was published in the Federal Register on January 19, 2007 (72 FR 
2469). That NPRM proposed to continue the requirements of AD 98-16-05. 
These requirements are inspections of the lower door surrounding 
structure to detect cracks and corrosion; inspections to detect 
cracking of the holes of the corner doublers, the fail-safe ring, and 
the door frames of the door structures; and repair if necessary. That 
NPRM also proposed to mandate the previously optional terminating 
action, reduce the applicability of the existing AD, and add repetitive 
inspections behind scuff plates for certain affected airplanes.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments that have been 
received on the NPRM.

Request To Give Credit for Previous Inspections

    FedEx concurs with the NPRM, but requests that we give credit for 
previous inspections accomplished in accordance with AD 98-16-05. FedEx 
points out that this credit should be given for actions in paragraphs 
(f), (g), (j), (k), (n), and (r) of the NPRM.
    We partially agree with the request. We agree that it is necessary 
for the AD to give credit for inspections accomplished previously in 
accordance with AD 98-16-05. We disagree that it is necessary to change 
the AD in this regard. Paragraph (e) of the AD states ``You are 
responsible for having the actions required by this AD performed within 
the compliance times specified, unless the actions have already been 
done.'' Therefore, the AD already gives credit for required actions 
that were accomplished according to AD 98-16-05.

Request To Allow Previously Granted Alternate Methods of Compliance 
(AMOCs)

    FedEx also suggests that AMOCs issued per AD 98-16-05 be granted as 
applicable to the NPRM.
    We agree that we should approve AMOCs for this AD that were 
approved previously in accordance with AD 98-16-05. We disagree with 
changing the AD in this regard. Paragraph (t)(2) of both the NPRM and 
the AD already approves previous AMOCs.

Request To Address Repairs Outside Limits

    FedEx requests that we add wording to paragraphs (l)(2) and (t) of 
the NPRM to address repairs outside the applicable service bulletins or 
that exceed the service bulletin limits. (Airbus Service Bulletin A300-
53-6018, Revision 1, dated April 29, 1992; or Revision 02, dated 
November 27, 2000; are the applicable service bulletins for paragraph 
(l)(2); and paragraph (t) is the AMOC paragraph.) FedEx suggests the 
following wording: ``If any crack or corrosion is detected during any 
inspection required by this AD and the applicable service bulletin 
specifies to contact the manufacturer for disposition of corrective 
actions: Prior to further flight, repair in accordance with a method 
approved by either the Manager, International Branch, ANM-116, or DGAC/
EASA, or its delegated agent.''
    We disagree with the request to add the suggested words. There are 
no limits specified in the service bulletins. We cannot approve repairs 
that exceed the limits of the service bulletin unless the excess limits 
are defined. However, affected operators may request approval of AMOCs, 
under the provisions of paragraph (t) of the AD.

Conclusion

    We have carefully reviewed the available data, including the 
comments that have been submitted, and determined that air safety and 
the public interest require adopting the AD as proposed.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this AD. The average labor rate per work hour is $80.

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 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:

[[Page 30963]]

    (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 and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

Revision 04, dated January 24, 2005, at the applicable times 
specified in paragraphs (o)(1) and (o)(2) of this AD. Accomplishment 
of these inspections is not required for the mid and aft passenger/
crew doors if a steel doubler that covers the entire inspection area 
is installed.
    (1) For the forward and mid passenger/crew doors, the bulk cargo 
door, and the aft passenger/crew doors, except the upper and lower 
edges of the fail-safe ring and the upper edges of the corner 
doubler: Perform the first inspection within 60 months after 
accomplishing the inspection required by paragraph (n) of this AD; 
and repeat the inspection thereafter at intervals not to exceed 60 
months.
    (2) For the upper and lower edges of the fail-safe ring and the 
upper edges of the corner doubler of the aft passenger/crew doors: 
Perform the first inspection within 60 months or 6,000 landings 
after accomplishing the inspection required by paragraph (n) of this 
AD, whichever occurs first; and repeat the inspection thereafter at 
intervals not to exceed 60 months or 6,000 landings, whichever 
occurs first.

paragraph (o) of this AD, prior to further flight, repair in 
accordance with Airbus Service Bulletin A300-53-6022, Revision 04, 
dated January 24, 2005. Thereafter, perform the repetitive 
inspections required by paragraph (o) of this AD at the applicable 
times specified in paragraphs (o)(1) and (o)(2) of this AD.
    (q) If corrosion is found during any inspection required by 
paragraph (o) of this AD, prior to further flight, repair in 
accordance with Airbus Service Bulletin A300-53-6022, Revision 04, 
dated January 24, 2005. Thereafter, perform the repetitive 
inspections required by paragraph (g) of this AD at the applicable 
times specified in paragraph (q)(1) or (q)(2) of this AD.
    (1) For the upper and lower edges of the fail-safe ring and the 
upper edges of the corner doubler of the aft passenger/crew doors, 
and for the mid passenger/crew door: Inspect at intervals not to 
exceed 60 months or 5,000 landings, whichever occurs first.
    (2) For the forward passenger/crew doors and bulk cargo doors: 
Inspect at intervals not to exceed 60 months.

Terminating Modification for Repetitive Inspection of Corner Doublers, 
Fail-Safe Ring, and Door Frames

    (r) Before the accumulation of 30,000 total flight cycles since 
the date of issuance of the original French standard airworthiness 
certificate or the date of issuance of the original French export 
certificate of airworthiness, or during the next inspection required 
by paragraph (k) of this AD, whichever occurs later: Modify the 
passenger/crew door structures in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A300-53-6002, Revision 06, 
dated May 17, 2004. Accomplishment of this modification constitutes
