ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Airbus Model A319–100, A320–200,
A321–100, and A321–200 series
airplanes. This AD requires repetitive
inspections for corrosion in the inside
and outside lower walls of each type A,
D, E, and F lavatory wall that has at least
one wall-mounted cabin attendant seat,
and related investigative and corrective
actions if necessary. The repetitive
inspections may be terminated by
repairing the wall with composite
material, or replacing the entire wall
with a new wall made of composite
material. This AD results from reports of
corrosion in the lower part of the
lavatory walls due to water ingress. We
are issuing this AD to detect and correct
corrosion and damage on the lower part
of the lavatory walls, which could
compromise the structural integrity of
the cabin attendant seat attachments,
and cause injury to the cabin attendants
during a crash landing.
DATES: This AD becomes effective June
16, 2006.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of June 16, 2006.

SUPPLEMENTARY INFORMATION:
referenced as an appropriate source of
service information for accomplishing
the actions proposed in the AD). If the
French airworthiness directive and the
Airbus service bulletins are revised in
the future to reflect a changed repetitive
inspection interval, we may consider
further rulemaking. However, operators
may request an extension of the
compliance time as an alternative
method of compliance in accordance
with the procedures in paragraph (j) of
this AD. No change to the AD is
necessary in this regard.
Request To Extend Compliance Time
Based on Maintenance Schedule
Northwest Airlines requests that we
extend the compliance time for the
initial inspection to match its L-check
interval of 23 months with no flighthour limitations. Northwest Airlines
states that we did not provide
justification in the NPRM for either the
initial or repeat inspection intervals.
Northwest Airlines also notes that
corrosion is typically a factor of
calendar time, not flight hours.
Discussion
Northwest Airlines is convinced that an

(as long as) cabin attendant seats (CAS)
not used until lavatory wall is
repaired.’’ According to Northwest
Airlines, this contradicts the MEL,
which gives 3 days or 10 days,
depending on the CAS location, for
corrective action to be taken. Northwest
Airlines notes that since the flight
attendant will need to use a passenger
seat in the event that a CAS is blocked
off, an equivalent level of safety is
maintained regardless of how long it
takes to repair the seat.
We disagree that there is a conflict
between the compliance time for these
repairs that is stated in the AD and the
compliance time for the same repairs
that are specified in the MEL. The MEL
addresses inoperative equipment and
the ability to dispatch the airplane with
that equipment inoperative. This AD
addresses a situation where the
attachment of the CAS may be understrength due to corrosion damage. The
CAS is still usable, per se, and the AD
provides 600 flight hours within which
to repair any damage found as a result
of the required inspections. In this case
there is no conflict because of the two
totally different issues addressed by the
MEL and the AD. We do not agree to
allow repairs at the next scheduled
maintenance visit because the schedule
for maintenance visits can vary widely
among operators. No change to the AD
is necessary.
Explanation of Changes to Optional
Terminating Action Paragraph (h)
We have revised paragraph (h) to
include more detail about the applicable
component maintenance manual (CMM)
for each lavatory. We have also
specified that one of the repair options
must be done in accordance with a
method approved by the FAA or the
´ ´
Direction Generale de l’Aviation Civile
(DGAC) (or its delegated agent), but that
the applicable CMM is one approved
method. These changes provide more
information and flexibility for operators.
Conclusion
We have carefully reviewed the
available data, including the comments
received, 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 393 airplanes of
U.S. registry. The inspection takes about
2 work hours per lavatory, at an average
labor rate of $65 per work hour. Based
on these figures, the estimated cost of
E:\FR\FM\12MYR1.SGM
12MYR1
Federal Register / Vol. 71, No. 92 / Friday, May 12, 2006 / Rules and Regulations
the AD for U.S. operators is $51,090, or
$130 per lavatory, per inspection cycle.
Authority for This Rulemaking
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 and placed it in the AD docket.

to examine the regulatory evaluation.

gear (MLG) is installed, and replacing
the uplock axle with a new uplock axle
if necessary. This AD results from a
report of a cracked uplock axle caused
by hydrogen embrittlement during the
manufacturing process. We are issuing
this AD to prevent failure of the uplock
mechanism, which, combined with a
loss of hydraulic pressure, could result

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to certain Saab Model SAABFairchild SF340A (SAAB/SF340A) and
SAAB 340B airplanes. That NPRM was
published in the Federal Register on
March 7, 2006 (71 FR 11349). That
NPRM proposed to require a one-time
inspection to see if a faulty uplock axle
for the shock strut of the main landing
gear (MLG) is installed, and replacing
the uplock axle with a new uplock axle
if necessary.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the NPRM or on the
determination of the cost to the public.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed.
Costs of Compliance
This AD will affect about 248
airplanes of U.S. registry. The required
inspection will take about 1 work hour
per airplane, at an average labor rate of
$65 per work hour. Based on these
figures, the estimated cost of the AD for
U.S. operators is $16,120, or $65 per
airplane.
Authority for This Rulemaking
Title 49 of the United States Code

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus Model A319-100, A320-200, A321-100, and A321-200 series
airplanes. This AD requires repetitive inspections for corrosion in the
inside and outside lower walls of each type A, D, E, and F lavatory
wall that has at least one wall-mounted cabin attendant seat, and
related investigative and corrective actions if necessary. The
repetitive inspections may be terminated by repairing the wall with
composite material, or replacing the entire wall with a new wall made
of composite material. This AD results from reports of corrosion in the
lower part of the lavatory walls due to water ingress. We are issuing
this AD to detect and correct corrosion and damage on the lower part of
the lavatory walls, which could compromise the structural integrity of
the cabin attendant seat attachments, and cause injury to the cabin
attendants during a crash landing.
DATES: This AD becomes effective June 16, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of June 16, 2006.

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Airbus Model
A319-100, A320-200, A321-100, and A321-200 series airplanes. That NPRM
was published in the Federal Register on November 10, 2005 (70 FR
68384). That NPRM proposed to require repetitive inspections for
corrosion in the inside and outside lower walls of each type A, D, E,
and F lavatory wall that has at least one wall-mounted cabin attendant
seat, and related investigative and corrective actions if necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Extend Compliance Time Based on Future Revision of French AD
Airbus states that French airworthiness directive F-2005-046, dated
March 16, 2005, which is the parallel airworthiness directive for this
AD, will be revised to extend the repetitive inspection interval from
18 months to 20 months for airplanes on which no corrosion is found.
We infer that Airbus requests that we revise the NPRM to extend the
repetitive inspection interval. We disagree. Both the AD and the
current French airworthiness directive require repeat inspections at
the intervals defined in Airbus Service Bulletin A320-25-1365, dated
February 18, 2005 (which is referenced as an appropriate source of
service information for accomplishing the actions proposed in the AD).
If the French airworthiness directive and the Airbus service bulletins
are revised in the future to reflect a changed repetitive inspection
interval, we may consider further rulemaking. However, operators may
request an extension of the compliance time as an alternative method of
compliance in accordance with the procedures in paragraph (j) of this
AD. No change to the AD is necessary in this regard.
Request To Extend Compliance Time Based on Maintenance Schedule
Northwest Airlines requests that we extend the compliance time for
the initial inspection to match its L-check interval of 23 months with
no flight-hour limitations. Northwest Airlines states that we did not
provide justification in the NPRM for either the initial or repeat
inspection intervals. Northwest Airlines also notes that corrosion is
typically a factor of calendar time, not flight hours. Northwest
Airlines is convinced that an extension to 23 months with no flight-
hour limitation on the initial inspections would provide an equivalent
level of safety. Northwest Airlines states that this change to the
compliance times would give operators enough time to schedule the work
in the optimal maintenance environment.
We do not agree with the request to extend the compliance times. We
have determined that the compliance times proposed in the NPRM
represent the maximum interval of time allowable for the affected
airplanes to continue to safely operate before the inspections are
done. Since maintenance schedules vary among operators, it is not
possible to accommodate every operator's maintenance schedule. However,
operators may request an extension of the compliance time as an
alternative method of compliance in accordance with the procedures in
paragraph (j) of this AD. We have not changed the AD in this regard.
Request To Give Temporary Minimum Equipment List (MEL) Relief
Northwest Airlines also requests that we allow temporary MEL relief
to allow operators to make repairs at the next scheduled hangar
maintenance visit. Northwest Airlines explains that operators run a
considerable operational risk while complying with Airbus Service
Bulletin A320-25-1365. Northwest Airlines points out that the logic
diagram, Figure 1, Sheet 1, of the service bulletin, allows a
``Lavatory wall to be repaired within 600 flight hours (as long as)
cabin attendant seats (CAS) not used until lavatory wall is repaired.''
According to Northwest Airlines, this contradicts the MEL, which gives
3 days or 10 days, depending on the CAS location, for corrective action
to be taken. Northwest Airlines notes that since the flight attendant
will need to use a passenger seat in the event that a CAS is blocked
off, an equivalent level of safety is maintained regardless of how long
it takes to repair the seat.
We disagree that there is a conflict between the compliance time
for these repairs that is stated in the AD and the compliance time for
the same repairs that are specified in the MEL. The MEL addresses
inoperative equipment and the ability to dispatch the airplane with
that equipment inoperative. This AD addresses a situation where the
attachment of the CAS may be under-strength due to corrosion damage.
The CAS is still usable, per se, and the AD provides 600 flight hours
within which to repair any damage found as a result of the required
inspections. In this case there is no conflict because of the two
totally different issues addressed by the MEL and the AD. We do not
agree to allow repairs at the next scheduled maintenance visit because
the schedule for maintenance visits can vary widely among operators. No
change to the AD is necessary.
Explanation of Changes to Optional Terminating Action Paragraph (h)
We have revised paragraph (h) to include more detail about the
applicable component maintenance manual (CMM) for each lavatory. We
have also specified that one of the repair options must be done in
accordance with a method approved by the FAA or the Direction
G[eacute]n[eacute]rale de l'Aviation Civile (DGAC) (or its delegated
agent), but that the applicable CMM is one approved method. These
changes provide more information and flexibility for operators.
Conclusion
We have carefully reviewed the available data, including the
comments received, 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 393 airplanes of U.S. registry. The
inspection takes about 2 work hours per lavatory, at an average labor
rate of $65 per work hour. Based on these figures, the estimated cost
of
[[Page 27597]]
the AD for U.S. operators is $51,090, or $130 per lavatory, per
inspection cycle.
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:
(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.
