AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Supplemental notice of
proposed rulemaking (NPRM);
reopening of comment period.
SUMMARY: We are revising an earlier
NPRM for the products listed above.
This action revises the earlier NPRM by
expanding the scope. This AD results
from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as: Several cases of corrosion
and damage on the Down Drive Shafts
(DDS), between the Down Drive Gear
Box (DDGB) and the Input Gear Box
(IPGB), on all 10 Flap Tracks (5 per
wing), have been reported by AIRBUS
Long Range Operators. Investigations
have revealed that corrosion and wear
due to absence of grease in the spline
interfaces could cause [DDS]
disconnection which could result in a
free movable flap surface, potentially
leading to aircraft asymmetry or even
flap detachment.
The unsafe condition could reduce
the ability of the flightcrew to maintain
the safe flight and landing of the
airplane. The proposed AD would
require actions to correct the unsafe
condition on these products.

Discussion
We proposed to amend 14 CFR part
39 with an earlier NPRM for the
specified products, which was
published in the Federal Register on
January 13, 2009 (74 FR 1649). That
earlier NPRM proposed to correct an
unsafe condition for the products listed
above.
Since that NPRM was issued, we have
determined that the actions specified in
paragraph (f)(1)(ii) of the NPRM need to
be clarified in order for us to provide
adequate notice and opportunity for
public comment. Paragraph (g)(1)(ii) of
the NPRM specifies to inspect flap
tracks 2 and 4 and do all applicable
corrective actions (replacing damaged
parts). This supplemental NPRM would
also require inspecting flap tracks 1, 3,
and 5.
Explanation of Revised Service
Information
Airbus has issued the revised service
information specified in the following
table. We have added the applicable
revised service information to paragraph
(g) of this supplemental NPRM as the
appropriate sources of service
information for accomplishing the
required actions.

Request To Clarify Actions in the Latest
Service Bulletin Revisions
The Air Transport Association (ATA),
on behalf of Northwest Airlines (NWA),
states that the service bulletins referred
to in the original NPRM have been
revised and asks which revisions of the
service bulletins should be used to
accomplish the actions. NWA notes that
the inspection procedures specified in
Airbus Mandatory Service Bulletin
A330–27–3152, Revision 02, dated
September 23, 2008, are more restrictive
than those in the original issue of
Airbus Mandatory Service Bulletin
A330–27–3152, dated August 9, 2007.
NWA adds that the original issue of
Airbus Mandatory Service Bulletin
A330–27–3152, dated August 9, 2007,
does not specify parts replacement for
Type 1 and Type 2 category findings
during the inspection; however, Airbus
Mandatory Service Bulletin A330–27–
3152, Revision 02, specifies replacement
of the input gear box (IPGB) within 18
months. NWA asks that the intent of the
inspection and replacement
requirements be clarified.

We agree that some clarification is
necessary, as follows. As stated
previously, the latest revisions of Airbus
Mandatory Service Bulletins A330–27–
3152, Revision 02, and A340–27–4151,
Revision 01, are cited in the
supplemental NPRM for accomplishing
the proposed actions. The changes in
Airbus Mandatory Service Bulletins
A330–27–3152, Revision 02, and A340–
27–4151, Revision 01, are minor and no
additional work is necessary for
airplanes on which the actions have
been done using those revisions.
The NPRM proposed to require
replacing all damaged parts before
further flight, regardless of the type of
damage; however, the revised service
information changed the actions for
Type 2 damaged parts from ‘‘no
replacement required’’ to ‘‘replacement
within 18 months.’’ This action is only
applicable if Type 2 damaged parts are
found. It is not necessary to replace
Type 1 damaged parts.
Requests To Extend Compliance Time
ATA, on behalf of its member NWA,
also notes that the compliance time of
18 months for the IPGB replacement,
and a compliance time of 20 months for
the initial inspection, as specified in
paragraph (g)(2) of the original NPRM,
should be extended to 24 months to
align with its ‘‘C’’ check intervals. NWA
adds that the Airbus service information
refers to General Electric (Smiths)
Service Bulletin 6975–27–018, dated
August 2007, to define Type 2 damage
findings. NWA states that allowing a 24month compliance period, instead of 18

months, for Type 2 damage findings on
airplanes up to 6 years old would still
require IPGB replacement within 8 years
since the airworthiness certification
date, which is substantially less than the
12 years specified in the Airbus service
information and the EASA AD. In
addition, NWA notes that new grease is
applied to the splined area following the
6-year inspection, reducing additional
wear and corrosion during the 24-month
period before IPGB replacement.
We disagree with the commenter’s
request that the compliance time should
be extended to 24 months to align with
‘‘C’’ check intervals. In developing an
appropriate compliance time for this
action, we considered the urgency
associated with the subject unsafe
condition, the availability of required
parts, and the practical aspect of
accomplishing the required actions
within a period of time that corresponds
to the normal scheduled maintenance
for most affected operators. In light of
these items, we have determined that an
18-month compliance time for the IPGB
replacement, and a 20-month
compliance time for the inspections
specified in paragraph (g)(2) of this
supplemental NPRM, are appropriate.
However, under the provisions of
paragraph (h)(1) of the supplemental
NPRM, we will consider requests to
adjust the compliance time if sufficient
data are submitted to substantiate that
the new compliance time would provide
an acceptable level of safety. We have
made no change to the original NPRM
in this regard.
E:\FR\FM\29MRP1.SGM
29MRP1
Federal Register / Vol. 75, No. 59 / Monday, March 29, 2010 / Proposed Rules
Another commenter, Elvio Marinelli,
asks that the compliance time of ‘‘before
further flight’’ for doing the corrective
actions specified in paragraphs (f)(1)(i),
(f)(1)(ii), (f)(1)(iii), (f)(1)(iv), and (f)(2) of
the original NPRM, be changed to match
the language in the EASA AD which
requires accomplishing the corrective
actions within the compliance time
defined in Airbus Mandatory Service
Bulletins A330–27–3152 and A340–27–
4151. The commenter adds that the
compliance time in Airbus Mandatory
Service Bulletins A330–27–3152 and
A340–27–4151 allows continued flight
with a certain extent of damage to the
down drive shafts (DDS) and the IPGB,
which defers the replacement.
We acknowledge that the original
NPRM proposed to require replacing all
damaged parts before further flight,
regardless of type of damage; however,
the revised service information changed
the actions for Type 2 damaged parts.
Therefore, we have revised this
supplemental NPRM to clarify that Type
3 damaged parts must be repaired before
further flight and that certain Type 2
damaged parts must be repaired within
18 months. It is not necessary to replace
Type 1 damaged parts.
srobinson on DSKHWCL6B1PROD with PROPOSALS
Request To Remove Reporting
Requirement
ATA, on behalf of its member NWA,
asks that the requirement to report
inspection findings to Airbus be
removed from the original NPRM. NWA
states that the referenced Airbus service
information specifies that findings from
each inspection be sent to Airbus. NWA
asks that the original NPRM clearly state
that this is not a requirement.
We disagree with the commenter’s
request that the reporting requirement
should be removed from this
supplemental NPRM, or language added
to state that no reporting is required. We
have determined that reporting the
inspection findings will enable the
manufacturer to obtain better insight
into the prevalence of the damage.
Access to all findings will also help the
manufacturer to develop final action to
address the identified unsafe condition
in a timely manner. We have made no
change to the proposed AD in this
regard.
Request To Include Parts Cost
ATA, on behalf of its member NWA,
asks that a parts cost of $11,000 per
airplane for the corrective action be
added to the original NPRM. ATA states
that the cost of compliance is
underestimated because the parts cost
was not included. NWA notes that
industry data provided by Airbus
indicate that 10 to 15 percent of all DDS
VerDate Nov<24>2008
16:34 Mar 26, 2010
Jkt 220001
and IPGB parts inspected require
replacement. NWA adds that using
these industry findings, rates and repair
costs provided to NWA by the supplier
are approximately $11,000.
We disagree with the commenter’s
request that the parts cost be included
in this supplemental NPRM. The data in
the Costs of Compliance section (below)
are limited to the cost of actions actually
required by the supplemental NPRM.
The cost analysis in AD rulemaking
actions does not include the costs of
‘‘on-condition’’ actions (e.g., ‘‘repair or
replace, if necessary’’) or replacement
parts that are necessary when doing
those on-condition actions. Regardless
of AD direction, those actions would be
required to correct an unsafe condition
identified on an airplane and ensure
operation of that airplane in an
airworthy condition. Therefore, we have
made no change to the supplemental
NPRM in this regard.
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.
Certain changes described above
expand the scope of the earlier NPRM.
As a result, we have determined that it
is necessary to reopen the comment
period to provide additional
opportunity for the public to comment
on this proposed AD.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
highlighted in a Note within the AD.

Explanation of Change to Costs of
Compliance
Since issuance of the original NPRM,
we have increased the labor rate used in
the Costs of Compliance from $80 per
work hour to $85 per work hour. The
Costs of Compliance information,
below, reflects this increase in the
specified hourly labor rate.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD affects
about 41 products of U.S. registry. We
also estimate that it takes about 65
work-hours per product to comply with
the basic requirements of this proposed
AD. The average labor rate is $85 per
work-hour. Based on these figures, we
estimate the cost of the proposed AD on
U.S. operators to be $226,525, or $5,525
per product.
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
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); and
3. Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities

The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
AIRBUS: Docket No. FAA–2009–0003;
Directorate Identifier 2007–NM–251–AD.
Affected ADs
(b) None.
Subject
(d) Air Transport Association (ATA) of
America Code 27: Flight Controls.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Several cases of corrosion and damage on
the Down Drive Shafts (DDS), between the
Down Drive Gear Box (DDGB) and the Input
Gear Box (IPGB), on all 10 Flap Tracks (5 per
wing), have been reported by AIRBUS Long
Range Operators.
Investigations have revealed that corrosion
and wear due to absence of grease in the
spline interfaces could cause [DDS]
disconnection which could result in a free
movable flap surface, potentially leading to
aircraft asymmetry or even flap detachment.
Emergency Airworthiness Directive (EAD)
2007–0222–E mandated on all aircraft older
than 6 years since AIRBUS original delivery
date of the aircraft, an initial inspection of all
DDS and IPGB for corrosion and wear
detection in order to replace any damaged
part.
Revision 1 of EAD 2007–0222–E aimed for
clarifying the compliance instructions.
[EASA AD 2008–0026] supersedes the EAD
2007–0222R1–E and mandates repetitive
inspections every 6 years for all the fleet.
The unsafe condition could reduce the ability
of the flightcrew to maintain the safe flight
and landing of the airplane. The corrective
actions include replacing damaged parts.
Compliance
(f) You are responsible for having the
actions required by this AD performed within
the compliance times specified, unless the
actions have already been done.
Actions
(g) Do the applicable inspections and
corrective actions specified in paragraphs
(g)(1) and (g)(2) of this AD, in accordance
with the instructions of the applicable
service information specified in Table 1 of
this AD.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of

-----------------------------------------------------------------------
SUMMARY: We are revising an earlier NPRM for the products listed above.
This action revises the earlier NPRM by expanding the scope. This AD
results from mandatory continuing airworthiness information (MCAI)
originated by an aviation authority of another country to identify and
correct an unsafe condition on an aviation product. The MCAI describes
the unsafe condition as: Several cases of corrosion and damage on the
Down Drive Shafts (DDS), between the Down Drive Gear Box (DDGB) and the
Input Gear Box (IPGB), on all 10 Flap Tracks (5 per wing), have been
reported by AIRBUS Long Range Operators. Investigations have revealed
that corrosion and wear due to absence of grease in the spline
interfaces could cause [DDS] disconnection which could result in a free
movable flap surface, potentially leading to aircraft asymmetry or even
flap detachment.
The unsafe condition could reduce the ability of the flightcrew to
maintain the safe flight and landing of the airplane. The proposed AD
would require actions to correct the unsafe condition on these
products.
DATES: We must receive comments on this proposed AD by April 23, 2010.

Discussion
We proposed to amend 14 CFR part 39 with an earlier NPRM for the
specified products, which was published in the Federal Register on
January 13, 2009 (74 FR 1649). That earlier NPRM proposed to correct an
unsafe condition for the products listed above.
Since that NPRM was issued, we have determined that the actions
specified in paragraph (f)(1)(ii) of the NPRM need to be clarified in
order for us to provide adequate notice and opportunity for public
comment. Paragraph (g)(1)(ii) of the NPRM specifies to inspect flap
tracks 2 and 4 and do all applicable corrective actions (replacing
damaged parts). This supplemental NPRM would also require inspecting
flap tracks 1, 3, and 5.
Explanation of Revised Service Information
Airbus has issued the revised service information specified in the
following table. We have added the applicable revised service
information to paragraph (g) of this supplemental NPRM as the
appropriate sources of service information for accomplishing the
required actions.

Comments
We have considered the following comments received on the earlier
NPRM.
Request To Clarify Actions in the Latest Service Bulletin Revisions
The Air Transport Association (ATA), on behalf of Northwest
Airlines (NWA), states that the service bulletins referred to in the
original NPRM have been revised and asks which revisions of the service
bulletins should be used to accomplish the actions. NWA notes that the
inspection procedures specified in Airbus Mandatory Service Bulletin
A330-27-3152, Revision 02, dated September 23, 2008, are more
restrictive than those in the original issue of Airbus Mandatory
Service Bulletin A330-27-3152, dated August 9, 2007. NWA adds that the
original issue of Airbus Mandatory Service Bulletin A330-27-3152, dated
August 9, 2007, does not specify parts replacement for Type 1 and Type
2 category findings during the inspection; however, Airbus Mandatory
Service Bulletin A330-27-3152, Revision 02, specifies replacement of
the input gear box (IPGB) within 18 months. NWA asks that the intent of
the inspection and replacement requirements be clarified.
We agree that some clarification is necessary, as follows. As
stated previously, the latest revisions of Airbus Mandatory Service
Bulletins A330-27-3152, Revision 02, and A340-27-4151, Revision 01, are
cited in the supplemental NPRM for accomplishing the proposed actions.
The changes in Airbus Mandatory Service Bulletins A330-27-3152,
Revision 02, and A340-27-4151, Revision 01, are minor and no additional
work is necessary for airplanes on which the actions have been done
using those revisions.
The NPRM proposed to require replacing all damaged parts before
further flight, regardless of the type of damage; however, the revised
service information changed the actions for Type 2 damaged parts from
``no replacement required'' to ``replacement within 18 months.'' This
action is only applicable if Type 2 damaged parts are found. It is not
necessary to replace Type 1 damaged parts.
Requests To Extend Compliance Time
ATA, on behalf of its member NWA, also notes that the compliance
time of 18 months for the IPGB replacement, and a compliance time of 20
months for the initial inspection, as specified in paragraph (g)(2) of
the original NPRM, should be extended to 24 months to align with its
``C'' check intervals. NWA adds that the Airbus service information
refers to General Electric (Smiths) Service Bulletin 6975-27-018, dated
August 2007, to define Type 2 damage findings. NWA states that allowing
a 24-month compliance period, instead of 18 months, for Type 2 damage
findings on airplanes up to 6 years old would still require IPGB
replacement within 8 years since the airworthiness certification date,
which is substantially less than the 12 years specified in the Airbus
service information and the EASA AD. In addition, NWA notes that new
grease is applied to the splined area following the 6-year inspection,
reducing additional wear and corrosion during the 24-month period
before IPGB replacement.
We disagree with the commenter's request that the compliance time
should be extended to 24 months to align with ``C'' check intervals. In
developing an appropriate compliance time for this action, we
considered the urgency associated with the subject unsafe condition,
the availability of required parts, and the practical aspect of
accomplishing the required actions within a period of time that
corresponds to the normal scheduled maintenance for most affected
operators. In light of these items, we have determined that an 18-month
compliance time for the IPGB replacement, and a 20-month compliance
time for the inspections specified in paragraph (g)(2) of this
supplemental NPRM, are appropriate. However, under the provisions of
paragraph (h)(1) of the supplemental NPRM, we will consider requests to
adjust the compliance time if sufficient data are submitted to
substantiate that the new compliance time would provide an acceptable
level of safety. We have made no change to the original NPRM in this
regard.
[[Page 15355]]
Another commenter, Elvio Marinelli, asks that the compliance time
of ``before further flight'' for doing the corrective actions specified
in paragraphs (f)(1)(i), (f)(1)(ii), (f)(1)(iii), (f)(1)(iv), and
(f)(2) of the original NPRM, be changed to match the language in the
EASA AD which requires accomplishing the corrective actions within the
compliance time defined in Airbus Mandatory Service Bulletins A330-27-
3152 and A340-27-4151. The commenter adds that the compliance time in
Airbus Mandatory Service Bulletins A330-27-3152 and A340-27-4151 allows
continued flight with a certain extent of damage to the down drive
shafts (DDS) and the IPGB, which defers the replacement.
We acknowledge that the original NPRM proposed to require replacing
all damaged parts before further flight, regardless of type of damage;
however, the revised service information changed the actions for Type 2
damaged parts. Therefore, we have revised this supplemental NPRM to
clarify that Type 3 damaged parts must be repaired before further
flight and that certain Type 2 damaged parts must be repaired within 18
months. It is not necessary to replace Type 1 damaged parts.
Request To Remove Reporting Requirement
ATA, on behalf of its member NWA, asks that the requirement to
report inspection findings to Airbus be removed from the original NPRM.
NWA states that the referenced Airbus service information specifies
that findings from each inspection be sent to Airbus. NWA asks that the
original NPRM clearly state that this is not a requirement.
We disagree with the commenter's request that the reporting
requirement should be removed from this supplemental NPRM, or language
added to state that no reporting is required. We have determined that
reporting the inspection findings will enable the manufacturer to
obtain better insight into the prevalence of the damage. Access to all
findings will also help the manufacturer to develop final action to
address the identified unsafe condition in a timely manner. We have
made no change to the proposed AD in this regard.
Request To Include Parts Cost
ATA, on behalf of its member NWA, asks that a parts cost of $11,000
per airplane for the corrective action be added to the original NPRM.
ATA states that the cost of compliance is underestimated because the
parts cost was not included. NWA notes that industry data provided by
Airbus indicate that 10 to 15 percent of all DDS and IPGB parts
inspected require replacement. NWA adds that using these industry
findings, rates and repair costs provided to NWA by the supplier are
approximately $11,000.
We disagree with the commenter's request that the parts cost be
included in this supplemental NPRM. The data in the Costs of Compliance
section (below) are limited to the cost of actions actually required by
the supplemental NPRM. The cost analysis in AD rulemaking actions does
not include the costs of ``on-condition'' actions (e.g., ``repair or
replace, if necessary'') or replacement parts that are necessary when
doing those on-condition actions. Regardless of AD direction, those
actions would be required to correct an unsafe condition identified on
an airplane and ensure operation of that airplane in an airworthy
condition. Therefore, we have made no change to the supplemental NPRM
in this regard.
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.
Certain changes described above expand the scope of the earlier
NPRM. As a result, we have determined that it is necessary to reopen
the comment period to provide additional opportunity for the public to
comment on this proposed AD.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a Note within the AD.
Explanation of Change to Costs of Compliance
Since issuance of the original NPRM, we have increased the labor
rate used in the Costs of Compliance from $80 per work hour to $85 per
work hour. The Costs of Compliance information, below, reflects this
increase in the specified hourly labor rate.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
affects about 41 products of U.S. registry. We also estimate that it
takes about 65 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $226,525, or $5,525 per product.
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 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); and
3. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities
[[Page 15356]]
under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

AIRBUS Long Range Operators.
Investigations have revealed that corrosion and wear due to
absence of grease in the spline interfaces could cause [DDS]
disconnection which could result in a free movable flap surface,
potentially leading to aircraft asymmetry or even flap detachment.
Emergency Airworthiness Directive (EAD) 2007-0222-E mandated on
all aircraft older than 6 years since AIRBUS original delivery date
of the aircraft, an initial inspection of all DDS and IPGB for
corrosion and wear detection in order to replace any damaged part.
Revision 1 of EAD 2007-0222-E aimed for clarifying the
compliance instructions.
[EASA AD 2008-0026] supersedes the EAD 2007-0222R1-E and
mandates repetitive inspections every 6 years for all the fleet.
The unsafe condition could reduce the ability of the flightcrew to
maintain the safe flight and landing of the airplane. The corrective
actions include replacing damaged parts.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Actions
(g) Do the applicable inspections and corrective actions
specified in paragraphs (g)(1) and (g)(2) of this AD, in accordance
with the instructions of the applicable service information
specified in Table 1 of this AD.
