comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Required
parts would cost about $100 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
$3,120, or $260 per product.
Authority for This Rulemaking

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.

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.
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.

List of Subjects in 14 CFR Part 39
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
328
Support Services GMBH (Formerly
Avcraft Aerospace GmbH): Docket No.
FAA–2008–0297; Directorate Identifier
2007–NM–330–AD.
Comments Due Date
(a) We must receive comments by April 14,
2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Dornier Model
328–100 airplanes, certificated in any

Subject
(d) Air Transport Association (ATA) of
America Code 55: Stabilizers.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
During maintenance water has been found
in the elevator assembly.
The unsafe condition is water or ice
accumulating in the elevator assembly,
which could result in corrosion and
consequent reduced structural integrity of the
flight control surface, or an unbalanced flight
control surface. These conditions could
result in reduced controllability of the
airplane.
Actions and Compliance
(f) Within 90 days after the effective date
of this AD, unless already done, do the
following actions. Install a drain hole in the
lower skin of the left and right-hand elevator
horns in accordance with the
Accomplishment Instructions of Avcraft
Dornier Service Bulletin SB–328–55–450,
Revision 1, dated November 19, 2003.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, International
Branch, ANM–116, FAA, has the authority to
approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19.
Send information to ATTN: Dan Rodina,
Aerospace Engineer, International Branch,
ANM–116, FAA, Transport Airplane
Directorate, 1601 Lind Avenue, SW., Renton,
Washington 98057–3356; telephone (425)
227–2125; fax (425) 227–1149. Before using
any approved AMOC on any airplane to
which the AMOC applies, notify your
appropriate principal inspector (PI) in the
FAA Flight Standards District Office (FSDO),
or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement
in this AD to obtain corrective actions from
a manufacturer or other source, use these
actions if they are FAA-approved. Corrective
actions are considered FAA-approved if they
are approved by the State of Design Authority
(or their delegated agent). You are required
to assure the product is airworthy before it
is returned to service.
(3) Reporting Requirements: For any
reporting requirement in this AD, under the
provisions of the Paperwork Reduction Act,
the Office of Management and Budget (OMB)
has approved the information collection
requirements and has assigned OMB Control
Number 2120–0056.

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:
Cracks have been found in the propeller
blades and propeller hubs, for which ongoing
controlling actions issued by the propeller
TC [type certificate] holder (McCauley
Propeller Systems) have been mandated by
FAA Airworthiness Directive (AD) action.
Current FAA ADs related to this subject are

Cracking of the blade or hub can ultimately
lead to blade release with potentially
catastrophic consequences. * * *

4100 Series AFM. The actions described
in this service information are intended
to correct the unsafe condition
identified in the MCAI.
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 2007–0268,
dated October 8, 2007 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
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
highlighted in a NOTE within the
proposed AD.
Cracks have been found in the propeller
blades and propeller hubs, for which ongoing
controlling actions issued by the propeller
TC [type certificate] holder (McCauley
Propeller Systems) have been mandated by
FAA Airworthiness Directive (AD) action.
Current FAA ADs related to this subject are
2003–17–10 (which superseded AD 2003–
15–01), 2004–23–16, 2005–24–08 and 2006–
15–13.
Cracking of the blade or hub can ultimately
lead to blade release with potentially
catastrophic consequences. BAE Systems has
concluded that safety margins can be further
improved by introducing operating
limitations that will prevent damaging
stresses in the propeller assembly, instructing
flight crews to place the propeller condition
levers in the Flight position during all
ground maneuvering.
EASA concurs with this conclusion and
this AD therefore requires the replacement of
the Propeller Limitations Placard with a new
one.
Corrective actions include revising the
airplane flight manual. You may obtain
further information by examining the
MCAI in the AD docket.

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.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 7 products of U.S. registry.
We also estimate that it would take
about 2 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 $25 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 $1,295, or $185 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,

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

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

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.

ADDRESSES:
Examining the AD Docket
SUMMARY: The FAA is revising an earlier
NPRM for an airworthiness directive
(AD) that applies to all Airbus Model
A318, A319, A320, and A321 airplanes.
The original NPRM would have
superseded an existing AD that
currently requires inspecting to
determine the part number and serial
number of the fuel tank boost pumps
and, for airplanes with affected pumps,
revising the airplane flight manual
(AFM) and the FAA-approved
maintenance program. The existing AD
also provides for optional terminating
action for compliance with the revisions
to the AFM and the maintenance
program. The original NPRM proposed
to require modifying or replacing the
fuel tank boost pumps, which would
terminate the AFM limitations and the
maintenance program revisions. The
original NPRM resulted from a report
that a fuel tank boost pump failed in
service, due to a detached screw of the
boost pump housing that created a short
circuit between the stator and rotor of
the boost pump motor and tripped a
circuit breaker. This new action revises
the original NPRM by excluding certain
modified airplanes from the
applicability, requiring the AFM/
maintenance program revisions on
additional airplanes, and requiring
modification or replacement of
additional fuel tank boost pumps. We
are proposing this supplemental NPRM
to prevent electrical arcing in the fuel
tank boost pump motor, which, in the
presence of a combustible air-fuel
mixture in the pump, could result in an
explosion and loss of the airplane.
VerDate Aug<31>2005
We must receive comments on
this supplemental NPRM by April 7,
2008.

2006–12–02, amendment 39–14626 (71
FR 34814, June 16, 2006). The existing
AD applies to all Airbus Model A318,
A319, A320, and A321 airplanes. The
original NPRM was published in the
Federal Register on January 25, 2007
(72 FR 3371). The original NPRM
proposed to retain the existing AD’s
requirements (identifying airplanes with
certain fuel tank boost pumps and, for
those airplanes, revising the airplane
flight manual (AFM) and maintenance
program, with optional terminating
action). The original NPRM also
proposed to require modifying or
replacing the fuel tank boost pumps,
which would terminate the AFM
limitations and maintenance program
revisions.
Actions Since Original NPRM Was
Issued
Since we issued the original NPRM,
the European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has notified us that the
unsafe condition could exist on
airplanes with any Type 8410 fuel
pump having part number (P/N) 568–1–
27202–001, –002, or –005. (The original
NPRM would have applied only to
airplanes with Type 8410 fuel pumps
having P/N 568–1–27202–005 with
serial number 6137 and subsequent.)
Relevant Service Information
Airbus has issued Service Bulletin
A320–28–1159, dated January 8, 2007.
The service bulletin describes
procedures for determining the type and
part number of the fuel pumps, and for
modifying or replacing certain fuel
pumps. Accomplishing the actions
specified in the service information is
intended to adequately address the
unsafe condition. The EASA mandated
the service information and issued
airworthiness directive 2007–0218,
dated August 10, 2007, to ensure the
continued airworthiness of these
airplanes in the European Union.
The service bulletin refers to EATON
Service Bulletin 8410–28–05, dated
October 2, 2006, as an additional source
of service information for the actions
associated with the modification.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed
[[Page 13505]]
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:
Cracks have been found in the propeller blades and propeller
hubs, for which ongoing controlling actions issued by the propeller
TC [type certificate] holder (McCauley Propeller Systems) have been
mandated by FAA Airworthiness Directive (AD) action.
Current FAA ADs related to this subject are 2003-17-10 (which
superseded AD 2003-15-01), 2004-23-16, 2005-24-08 and 2006-15-13.
Cracking of the blade or hub can ultimately lead to blade
release with potentially catastrophic consequences. * * *
* * * * *
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.

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 2007-0268, dated October 8, 2007 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
Cracks have been found in the propeller blades and propeller
hubs, for which ongoing controlling actions issued by the propeller
TC [type certificate] holder (McCauley Propeller Systems) have been
mandated by FAA Airworthiness Directive (AD) action.
Current FAA ADs related to this subject are 2003-17-10 (which
superseded AD 2003-15-01), 2004-23-16, 2005-24-08 and 2006-15-13.
Cracking of the blade or hub can ultimately lead to blade
release with potentially catastrophic consequences. BAE Systems has
concluded that safety margins can be further improved by introducing
operating limitations that will prevent damaging stresses in the
propeller assembly, instructing flight crews to place the propeller
condition levers in the Flight position during all ground
maneuvering.
EASA concurs with this conclusion and this AD therefore requires
the replacement of the Propeller Limitations Placard with a new one.
Corrective actions include revising the airplane flight manual. You may
obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
BAE Systems (Operations) Limited has issued Service Bulletin J41-
11-027, dated March 29, 2007; General Amendment G12, approved January
2007, to the Jetstream 4100 Series Airplane Flight Manual (AFM); and
Advance Amendment Bulletin No. 13, approved April 4, 2007, to the
Jetstream 4100 Series AFM. 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
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 7 products of U.S. registry. We also estimate that
it would take about 2 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 $25 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 $1,295, or $185 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,
[[Page 13506]]
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:
BAE Systems (Operations) Limited (Formerly British Aerospace
Regional Aircraft): Docket No. FAA-2008-0275; Directorate Identifier
2007-NM-335-AD.
Comments Due Date
(a) We must receive comments by April 14, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to BAE Systems (Operations) Limited
(Jetstream) Model 4101 airplanes, all serial numbers, certificated
in any category.
Subject
(d) Air Transport Association (ATA) of America Code 11: Placards
and Markings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Cracks have been found in the propeller blades and propeller
hubs, for which ongoing controlling actions issued by the propeller
TC [type certificate] holder (McCauley Propeller Systems) have been
mandated by FAA Airworthiness Directive (AD) action.
Current FAA ADs related to this subject are 2003-17-10 (which
superseded AD 2003-15-01), 2004-23-16, 2005-24-08 and 2006-15-13.
Cracking of the blade or hub can ultimately lead to blade
release with potentially catastrophic consequences. BAE Systems has
concluded that safety margins can be further improved by introducing
operating limitations that will prevent damaging stresses in the
propeller assembly, instructing flight crews to place the propeller
condition levers in the Flight position during all ground
maneuvering.
EASA concurs with this conclusion and this AD therefore requires
the replacement of the Propeller Limitations Placard with a new one.
Corrective actions include revising the airplane flight manual.
Actions and Compliance
(f) Within 90 days after the effective date of this AD, unless
already done, do the following actions.
(1) Replace the existing Propeller Limitations Placard in the
cockpit with a new placard, in accordance with the Accomplishment
Instructions of BAE Systems (Operations) Limited Service Bulletin
J41-11-027, dated March 29, 2007.
(2) Revise the BAE Jetstream Series 4100 Airplane Flight Manual
(AFM) to include the information in BAE Jetstream Series 4100
General Amendment G12, approved January 2007, and BAE Jetstream
Series 4100 Advance Amendment Bulletin No. 13, approved April 4,
2007. General Amendment G12 describes a rolling take-off technique
and the reduced possibility of landing with ice contaminating the
wings, and adds a Gross Height/Pressure Altitude Conversion Chart.
Advance Amendment Bulletin No. 13 introduces procedures for placing
the propeller condition levers in the Flight position during all
ground maneuvering. Operate the airplane according to the procedures
in General Amendment G12 and Advance Amendment Bulletin No. 13.
Note 1: This may be done by inserting copies of General
Amendment G12 and Advance Amendment Bulletin No. 13 into the AFM.
When General Amendment G12 and Advance Amendment Bulletin No. 13
have been included in general revisions of the AFM, the general
revisions may be inserted in the AFM, provided the relevant
information in the general revision is identical to that in General
Amendment G12 and Advance Amendment Bulletin No. 13.
FAA AD Differences
Note 2: 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, ANM-116, Transport Airplane Directorate, FAA,
has the authority to approve AMOCs for this AD, if requested using
the procedures found in 14 CFR 39.19. Send information to ATTN: Todd
Thompson, Aerospace Engineer, International Branch, ANM-116,
Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton,
Washington 98057-3356; telephone (425) 227-1175; fax (425) 227-1149.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
0056.
