AGENCY:
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
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:
ebenthall on PRODPC60 with PROPOSALS
In-service experience has shown that a
fracture of the gerotor pump of the A320 RAT
[ram air turbine] may occur. This may lead
to the non-operation of the RAT in case of
an in-flight deployment.
The Non-Deployment or NonPressurization of the RAT, associated with a
double engine failure or a total loss of normal
electrical power generation constitutes an
unsafe condition.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2008–0034,
dated February 20, 2008 [corrected
February 21, 2008] (referred to after this
as ‘‘the MCAI’’), to correct an unsafe

condition for the specified products.
The MCAI states:
In-service experience has shown that a
fracture of the gerotor pump of the A320 RAT
[ram air turbine] may occur. This may lead
to the non-operation of the RAT in case of
an in-flight deployment.
The Non-Deployment or NonPressurization of the RAT, associated with a
double engine failure or a total loss of normal
electrical power generation constitutes an
unsafe condition.
This AD mandates the replacement of the
affected gerotor pump assembly, which will
provide the required improved reliability of
the RAT.
The implementation of this modification
was originally managed by an AIRBUS
monitoring campaign. However, the rate of
installation of the modification by operators
has not met the predicted target. As such and
to ensure continued compliance with the
certification requirements it is considered
necessary to require compliance by use of
[an] AD.

You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Service Bulletin
A320–29–1122, dated July 27, 2006. The
actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.
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.
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 proposed
different actions in this AD from those
in the MCAI in order to follow FAA
policies. Any such differences are

45175
Federal Register / Vol. 73, No. 150 / Monday, August 4, 2008 / Proposed Rules
highlighted in a Note within the
proposed AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 758 products of U.S.
registry. We also estimate that it would
take about 5 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Required
parts would cost about $0 per product.
Where the service information lists
required parts costs that are covered
under warranty, we have assumed that
there will be no charge for these costs.
As we do not control warranty coverage
for affected parties, some parties may
incur costs higher than estimated here.
Based on these figures, we estimate the
cost of the proposed AD on U.S.
operators to be $303,200, or $400 per
product.
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.
ebenthall on PRODPC60 with PROPOSALS
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

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.
Authority for This Rulemaking
VerDate Aug<31>2005
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 proposed AD and placed it in the
AD docket.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
Airbus: Docket No. FAA–2008–0832;
Directorate Identifier 2008–NM–067–AD.
Comments Due Date
(a) We must receive comments by
September 3, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Airbus Model
A318, A319, A320, and A321 airplanes,
certificated in any category; except airplanes
on which AIRBUS Modification 27189 was
done in production or AIRBUS Service
Bulletin A320–29–1100 was done in service,
and on which AIRBUS Modification 28413
was not done in production.
Subject
(d) Air Transport Association (ATA) of
America Code 29: Hydraulic power.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
In-service experience has shown that a
fracture of the gerotor pump of the A320 RAT
[ram air turbine] may occur. This may lead
to the non-operation of the RAT in case of
an in-flight deployment.
The Non-Deployment or NonPressurization of the RAT, associated with a
double engine failure or a total loss of normal
electrical power generation constitutes an
unsafe condition.
This AD mandates the replacement of the
affected gerotor pump assembly, which will
provide the required improved reliability of
the RAT.
The implementation of this modification
was originally managed by an AIRBUS
monitoring campaign. However, the rate of

Discussion
On January 5, 2007, we issued AD
2007–02–01, Amendment 39–14888 (72
FR 2177, January 18, 2007). That AD
required actions intended to address an
unsafe condition on the products listed
above.
Since we issued AD 2007–02–01, we
have determined that fire detector
threshold tolerances for the affected
airplanes do not identify the failure of
one engine fire detector loop out of the
two present on each engine. The
European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2007–0119,
dated May 2, 2007 (referred to after this
PO 00000

as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:

FAIL’’ that occurred on an in-service aircraft
revealed that the detector threshold
tolerances could not permit to identify the
failure of one single engine fire detector loop
out of the two present on each engine. The
fire detection system integrity is therefore not
correctly monitored.
Airworthiness Directive (AD) No 2006–
0356–E [which corresponds to FAA AD
2007–02–01] was initially issued to mandate
the verification of the fire detection system
integrity by a one time inspection.
The current AD mandates installation of
two new fire monitoring units of an
improved design, each one of them is capable
of monitoring the integrity of both detectors
on the associated engine.
You may obtain further information by
examining the MCAI in the AD docket.

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 proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
[[Page 45175]]
highlighted in a Note within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 758 products of U.S. registry. We also estimate that
it would take about 5 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $0 per product. Where the
service information lists required parts costs that are covered under
warranty, we have assumed that there will be no charge for these costs.
As we do not control warranty coverage for affected parties, some
parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $303,200, or $400 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 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
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.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Airbus: Docket No. FAA-2008-0832; Directorate Identifier 2008-NM-
067-AD.
Comments Due Date
(a) We must receive comments by September 3, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Airbus Model A318, A319, A320, and
A321 airplanes, certificated in any category; except airplanes on
which AIRBUS Modification 27189 was done in production or AIRBUS
Service Bulletin A320-29-1100 was done in service, and on which
AIRBUS Modification 28413 was not done in production.
Subject
(d) Air Transport Association (ATA) of America Code 29:
Hydraulic power.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
In-service experience has shown that a fracture of the gerotor
pump of the A320 RAT [ram air turbine] may occur. This may lead to
the non-operation of the RAT in case of an in-flight deployment.
The Non-Deployment or Non-Pressurization of the RAT, associated
with a double engine failure or a total loss of normal electrical
power generation constitutes an unsafe condition.
This AD mandates the replacement of the affected gerotor pump
assembly, which will provide the required improved reliability of
the RAT.
The implementation of this modification was originally managed
by an AIRBUS monitoring campaign. However, the rate of installation
of the modification by operators has not met the predicted target.
As such and to ensure continued compliance with the certification
requirements it is considered necessary to require compliance by use
of [an] AD.
* * * * *
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 15 months after the effective date of this AD,
identify the part number (P/N) and serial number (S/N) of the RAT in
accordance with the Accomplishment Instructions of Airbus Service
Bulletin A320-29-1122, dated July 27, 2006.
(2) For airplanes on which a RAT with P/N 680203037 is installed
that has a S/N between 0101 and 0354 inclusive: Before further
flight, replace the gerotor pump assembly and re-identify the RAT in
accordance with the service bulletin.
(3) For airplanes on which a RAT with P/N 680203037 is installed
that does not have a S/N between 0101 and 0354 inclusive, or a RAT
with a P/N other than P/N 680203037 is installed: No further action
is required by this AD.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: No differences.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, FAA, has the authority to approve AMOCs for
this AD, if requested using the procedures found in 14 CFR 39.19.
