ACTION: Supplemental notice of
proposed rulemaking (NPRM);
reopening of comment period.
AGENCY:
SUMMARY: The FAA is revising an earlier
NPRM for an airworthiness directive
(AD) that applies to certain Airbus
Model A300 B2, A300 B4, and A300–
600 series airplanes. The original NPRM
would have superseded two existing
ADs. One AD currently requires an
inspection for cracks of the lower
outboard flange of gantry No. 4 in the
main landing gear (MLG) bay area, and
repair if necessary. The other AD
currently requires, among other actions,
repetitive inspections of the gantry
lower flanges, and repair if necessary.
The original NPRM proposed to require
new repetitive inspections for cracks in
the lower flange of certain gantries, and
repair if necessary, which ends the
existing inspection requirements. The
original NPRM also provided for
optional terminating actions for the new
repetitive inspections. This new action
revises the original NPRM by including
additional airplanes that were excluded
from the applicability. We are proposing

this supplemental NPRM to detect and
correct fatigue cracks in the lower
flanges of gantries 1 through 5 inclusive
in the MLG bay area, which could result
in reduced structural integrity of the
fuselage, and consequent rapid
decompression of the airplane.

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) (the ‘‘original
NPRM’’) to amend 14 CFR part 39 to
include an AD that supersedes AD
2003–26–10, amendment 39–13408 (69
FR 867, January 7, 2004), and AD 2004–
18–13, amendment 39–13792 (69 FR
55329, September 14, 2004). The
original NPRM applied to certain Airbus
Model A300 B2 and A300 B4 series
airplanes; and Model A300 B4–600, B4–
600R, and F4–600R series airplanes, and
Model C4–605R Variant F airplanes
(collectively called A300–600 series
airplanes). The original NPRM was
published in the Federal Register on
January 26, 2006 (71 FR 4313). The
original NPRM proposed to continue to
require an inspection for cracks of the
lower outboard flange of gantry No. 4 in
the main landing gear (MLG) bay area,
and repair if necessary. The original
NPRM also proposed to continue to
require repetitive inspections of the
gantry lower flanges, and repair if
necessary. In addition, the original
NPRM proposed to require new
repetitive inspections for cracks in the
lower flange of certain gantries, and
repair if necessary, which ends the
existing inspection requirements. The
original NPRM also proposed optional
terminating actions for the new
repetitive inspections.
Comments
We have considered the following
comment on the original NPRM.

Request To Revise the Applicability
Airbus requests that airplanes on
which Airbus Modifications 13037
(Airbus Service Bulletins A300–53–
0380 and A300–53–6153) and 12413
(Airbus Service Bulletins A300–53–
0360 and A300–53–6132), as applicable,
have been installed in service, and
airplanes on which Airbus Modification
12924 has been incorporated in
production be excluded from Table 1—
Applicability of the original NPRM. The
commenter states that the effectivity of
French airworthiness directive F–2005–
091 R1, issued September 28, 2005,
takes these modification into account,
except for Airbus Modification 12924.
The commenter states that the Direction
´ ´
Generale de l’Aviation Civile (DGAC),
which is the airworthiness authority for
France, plans to revise French
airworthiness directive F–2005–091 R1
to address Airbus Modification 12924.
We do not agree with Airbus to
exclude airplanes on which a particular
modification or service bulletin has
been accomplished in service.
Paragraph (m) of this supplemental
NPRM includes an optional terminating
action for accomplishing the actions
specified in Airbus Service Bulletin
A300–53–0380, dated August 5, 2005;
Airbus Service Bulletin A300–53–0360,
dated May 3, 2002; Airbus Service
Bulleitn A300–53–6132, dated February
5, 2002; or Airbus Service Bulletin
A300–53–6153, dated August 24, 2005;
as applicable. If an operator chooses to
accomplish this optional terminating
action, it must continue to operate the
airplane in that configuration unless an
alternative method of compliance is
approved. Therefore, we have
determined that excluding those
airplanes from the applicability of this
supplemental NPRM is not appropriate.
This difference between French
airworthiness directive F–2005–091 R1
and this supplemental NPRM has been
coordinated with the DGAC.
We also do not agree with the
commenter to exclude airplanes on
which Airbus Modification 12924 has
been incorporated in production. We
have confirmed with the DGAC that the
omission of this modification in French
airworthiness directive F–2005–091 R1
was an oversight. However, since the
issuance of the original NPRM, we have
determined that all combinations of the
Airbus modifications specified in the
effectivity of French airworthiness
directive F–2005–091 R1 include an inservice service bulletin. Therefore, we
have revised Table 1 of the applicability
of this supplemental NPRM to not
include any exceptions for

$80 per work hour. The cost impact
information, below, reflects this
increase in the specified hourly labor
rate.
FAA’s Determination and Proposed
Requirements of the Supplemental
NPRM
The change to the applicability
discussed above expands the scope of
the original NPRM; therefore, we have
determined that it is necessary to reopen
Change to Labor Rate
After the original NPRM was issued,
we reviewed the figures we have used
over the past several years to calculate
AD costs to operators. To account for
various inflationary costs in the airline
industry, we find it necessary to
increase the labor rate used in these
calculations from $65 per work hour to
the comment period to provide
additional opportunity for public
comment on this supplemental NPRM.
This proposed AD would affect about
165 airplanes of U.S. registry. The
following table provides the estimated
costs for U.S. operators to comply with
this proposed AD. Not all actions must
be completed on all airplanes.

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.

13132. This proposed AD would 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 the proposed regulation:
1. Is not a ‘‘significant regulatory

-----------------------------------------------------------------------
SUMMARY: The FAA is revising an earlier NPRM for an airworthiness
directive (AD) that applies to certain Airbus Model A300 B2, A300 B4,
and A300-600 series airplanes. The original NPRM would have superseded
two existing ADs. One AD currently requires an inspection for cracks of
the lower outboard flange of gantry No. 4 in the main landing gear
(MLG) bay area, and repair if necessary. The other AD currently
requires, among other actions, repetitive inspections of the gantry
lower flanges, and repair if necessary. The original NPRM proposed to
require new repetitive inspections for cracks in the lower flange of
certain gantries, and repair if necessary, which ends the existing
inspection requirements. The original NPRM also provided for optional
terminating actions for the new repetitive inspections. This new action
revises the original NPRM by including additional airplanes that were
excluded from the applicability. We are proposing
[[Page 28616]]
this supplemental NPRM to detect and correct fatigue cracks in the
lower flanges of gantries 1 through 5 inclusive in the MLG bay area,
which could result in reduced structural integrity of the fuselage, and
consequent rapid decompression of the airplane.
DATES: We must receive comments on this supplemental NPRM by June 12,
2006.

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) (the
``original NPRM'') to amend 14 CFR part 39 to include an AD that
supersedes AD 2003-26-10, amendment 39-13408 (69 FR 867, January 7,
2004), and AD 2004-18-13, amendment 39-13792 (69 FR 55329, September
14, 2004). The original NPRM applied to certain Airbus Model A300 B2
and A300 B4 series airplanes; and Model A300 B4-600, B4-600R, and F4-
600R series airplanes, and Model C4-605R Variant F airplanes
(collectively called A300-600 series airplanes). The original NPRM was
published in the Federal Register on January 26, 2006 (71 FR 4313). The
original NPRM proposed to continue to require an inspection for cracks
of the lower outboard flange of gantry No. 4 in the main landing gear
(MLG) bay area, and repair if necessary. The original NPRM also
proposed to continue to require repetitive inspections of the gantry
lower flanges, and repair if necessary. In addition, the original NPRM
proposed to require new repetitive inspections for cracks in the lower
flange of certain gantries, and repair if necessary, which ends the
existing inspection requirements. The original NPRM also proposed
optional terminating actions for the new repetitive inspections.
Comments
We have considered the following comment on the original NPRM.
Request To Revise the Applicability
Airbus requests that airplanes on which Airbus Modifications 13037
(Airbus Service Bulletins A300-53-0380 and A300-53-6153) and 12413
(Airbus Service Bulletins A300-53-0360 and A300-53-6132), as
applicable, have been installed in service, and airplanes on which
Airbus Modification 12924 has been incorporated in production be
excluded from Table 1--Applicability of the original NPRM. The
commenter states that the effectivity of French airworthiness directive
F-2005-091 R1, issued September 28, 2005, takes these modification into
account, except for Airbus Modification 12924. The commenter states
that the Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC),
which is the airworthiness authority for France, plans to revise French
airworthiness directive F-2005-091 R1 to address Airbus Modification
12924.
We do not agree with Airbus to exclude airplanes on which a
particular modification or service bulletin has been accomplished in
service. Paragraph (m) of this supplemental NPRM includes an optional
terminating action for accomplishing the actions specified in Airbus
Service Bulletin A300-53-0380, dated August 5, 2005; Airbus Service
Bulletin A300-53-0360, dated May 3, 2002; Airbus Service Bulleitn A300-
53-6132, dated February 5, 2002; or Airbus Service Bulletin A300-53-
6153, dated August 24, 2005; as applicable. If an operator chooses to
accomplish this optional terminating action, it must continue to
operate the airplane in that configuration unless an alternative method
of compliance is approved. Therefore, we have determined that excluding
those airplanes from the applicability of this supplemental NPRM is not
appropriate. This difference between French airworthiness directive F-
2005-091 R1 and this supplemental NPRM has been coordinated with the
DGAC.
We also do not agree with the commenter to exclude airplanes on
which Airbus Modification 12924 has been incorporated in production. We
have confirmed with the DGAC that the omission of this modification in
French airworthiness directive F-2005-091 R1 was an oversight. However,
since the issuance of the original NPRM, we have determined that all
combinations of the Airbus modifications specified in the effectivity
of French airworthiness directive F-2005-091 R1 include an in-service
service bulletin. Therefore, we have revised Table 1 of the
applicability of this supplemental NPRM to not include any exceptions
for
[[Page 28617]]
accomplishing those Airbus modifications.
Change to Labor Rate
After the original NPRM was issued, we reviewed the figures we have
used over the past several years to calculate AD costs to operators. To
account for various inflationary costs in the airline industry, we find
it necessary to increase the labor rate used in these calculations from
$65 per work hour to $80 per work hour. The cost impact information,
below, reflects this increase in the specified hourly labor rate.
FAA's Determination and Proposed Requirements of the Supplemental NPRM
The change to the applicability discussed above expands the scope
of the original NPRM; therefore, we have determined that it is
necessary to reopen the comment period to provide additional
opportunity for public comment on this supplemental NPRM.
Costs of Compliance
This proposed AD would affect about 165 airplanes of U.S. registry.
The following table provides the estimated costs for U.S. operators to
comply with this proposed AD. Not all actions must be completed on all
airplanes.

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 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 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 the proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
[[Page 28618]]
2. Is not a ``significant rule'' under the 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 supplemental NPRM and placed it in the AD docket. See
the ADDRESSES section for a location to examine the regulatory
evaluation.
