Comments Due Date
(a) We must receive comments by May 14,
2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to DA 42 airplanes,
serial numbers 42.004 through 42.129,
42.177, and 42.AC001, certificated in any
category.
Subject
(d) Air Transport Association of America
(ATA) Code 72: Engine.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Shortly after an engine change, the
aluminium fitting attached to the engine
gearbox holding lines and fittings of the
propeller control system was found to be
cracked. This led to a pressure loss in the
propeller control system following a control
system malfunction and led to a in-flight
engine shutdown.
The broken fitting is part of the engine
installation and was initially a steel part. It
was later modified by the engine
manufacturer to an aluminium design.
Investigation determined that the area is
critical for cracks due to combination of
mass, material and installation torque values.
Diamond Aircraft Industries incorporated
¨
with Design Change MAM 42–184 an
additional bracket into production airplanes
to improve the installations and prevent
vibration cracks.
Actions and Compliance
(f) Unless already done, within 50 hours
time-in-service or 30 days after the effective
date of this AD, whichever occurs first,
install the additional steel bracket following
Diamond Aircraft Industries GmbH
Mandatory Service Bulletin NO. MSB–42–
024/3, dated September 19, 2006.
Note 1: If the above action was
accomplished following the procedures
described in Diamond Aircraft Industries
GmbH Mandatory Service Bulletin No. MSB–
42–024/2, dated August 31, 2006, you may
take ‘‘unless already done’’ credit, and no
further action per this AD is necessary.

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:
From airplanes that have installed the
Auxiliary Fuel Tank Optional Design Change
(O–M) No. 42–056, three in-service failures of
the auxiliary fuel tank venting system have
been reported. These failures have led to the

inability to supply the complete auxiliary
fuel quantity to the main tanks and the
collapse of the auxiliary tank. It is suspected
that the vent lines were obstructed either by
ice accretion under certain climatic
conditions or by blockage of the vent valves
because of fuel contaminants.
Undetected malfunctions of the venting
system and damaged auxiliary fuel tanks may
lead to a lower usable fuel quantity,
subsequent fuel starvation and/or fuel
spillage into the nacelle.
The proposed AD would require
actions that are intended to address the
unsafe condition described in the MCAI.
DATES: We must receive comments on
this proposed AD by May 14, 2007.

Discussion
cprice-sewell on PRODPC61 with PROPOSALS
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued AD No: 2007–
0047 (referred to after this as ‘‘the
MCAI’’), to correct an unsafe condition
for the specified products. The MCAI
states:
From airplanes that have installed the
Auxiliary Fuel Tank Optional Design Change
(O–M) No. 42–056, three in-service failures of
the auxiliary fuel tank venting system have
been reported. These failures have led to the
inability to supply the complete auxiliary
fuel quantity to the main tanks and the
collapse of the auxiliary tank. It is suspected
that the vent lines were obstructed either by
ice accretion under certain climatic
conditions or by blockage of the vent valves
because of fuel contaminants.
Undetected malfunctions of the venting
system and damaged auxiliary fuel tanks may
lead to a lower usable fuel quantity,
subsequent fuel starvation and/or fuel
spillage into the nacelle.
The MCAI requires:
* * * to check for proper operation the
auxiliary fuel tank venting system, and check
for damage the fuel tanks’ structure.
VerDate Aug<31>2005
14:53 Apr 12, 2007
Jkt 211001
* * * also requires installation of
ventilation holes in the filler caps’ fitting and
introduction of a temporary revision into the
Aircraft Maintenance Manual (AMM).
You may obtain further information
by examining the MCAI in the AD
docket.
Relevant Service Information
Diamond Aircraft Industries GmbH
has issued Mandatory Service Bulletin
No. MSB–42–032/1, dated January 24,
2007. The actions described in this
service information are intended to
correct the unsafe condition identified
in the MCAI.
FAA’s Determination and Requirements
of the 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 this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This Proposed 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 47 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.
Based on these figures, we estimate
the cost of the proposed AD on U.S.
operators to be $7,520, or $160 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.

ACTION: Proposed rule.
AGENCY:
SUMMARY: EPA is proposing to approve
a redesignation request and State
Implementation Plan (SIP) revisions
submitted by the Commonwealth of
Virginia. The Virginia Department of
Environmental Quality (VADEQ) is
requesting that the Hampton Roads
ozone nonattainment area (‘‘Hampton
Roads Area’’ or ‘‘Area’’) be redesignated
as attainment for the 8-hour ozone
national ambient air quality standard
(NAAQS). The Area is comprised of the
Cities of Chesapeake, Hampton,
Newport News, Norfolk, Poquoson,
Portsmouth, Suffolk, Virginia Beach,
and Williamsburg, and the Counties of
Gloucester, Isle of Wight, James City,
and York, Virginia. EPA is proposing to
approve the ozone redesignation request
for the Hampton Roads Area. In
conjunction with its redesignation
request, the Commonwealth submitted a
SIP revision consisting of a maintenance
plan for the Hampton Roads Area that
provides for continued attainment of the
8-hour ozone NAAQS for at least 10
years after redesignation. EPA is
proposing to make a determination that
the Hampton Roads Area has attained
the 8-hour ozone NAAQS, based upon
three years of complete, quality-assured
ambient air quality monitoring data for
2003–2005. EPA’s proposed approval of
the 8-hour ozone redesignation request
is based on its determination that the
Hampton Roads Area has met the
criteria for redesignation to attainment
specified in the Clean Air Act (CAA). In
addition, the Commonwealth of Virginia
has also submitted a 2002 base-year
inventory for the Hampton Roads Area,
and EPA is proposing to approve that
inventory for the Hampton Roads Area
as a SIP revision. EPA is also providing
information on the status of its
adequacy determination for the motor
vehicle emission budgets (MVEBs) that
are identified in the maintenance plan
for the Hampton Roads Area for
purposes of transportation conformity,
and is also proposing to approve those

venting system, and check for damage the fuel tanks' structure.
* * * also requires installation of ventilation holes in the
filler caps' fitting and introduction of a temporary revision into
the Aircraft Maintenance Manual (AMM).
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Diamond Aircraft Industries GmbH has issued Mandatory Service
Bulletin No. MSB-42-032/1, dated January 24, 2007. The actions
described in this service information are intended to correct the
unsafe condition identified in the MCAI.
FAA's Determination and Requirements of the 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 this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
Differences Between This Proposed 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 47 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.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $7,520, or $160 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

Comments Due Date
(a) We must receive comments by May 14, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model DA 42 airplanes; serial numbers
42.015, 42.028, 42.036, 42.044, 42.055, 42.059, 42.062, 42.067,

category.
Subject
(d) Air Transport Association of America (ATA) Code 28: Fuel.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
From airplanes that have installed the Auxiliary Fuel Tank
Optional Design Change (O[Auml]M) No. 42-056, three in-service
failures of the auxiliary fuel tank venting system have been
reported. These failures have led to the inability to supply the
complete auxiliary fuel quantity to the main tanks and the collapse
of the auxiliary tank. It is suspected that the vent lines were
obstructed either by ice accretion under certain climatic conditions
or by blockage of the vent valves because of fuel contaminants.
Undetected malfunctions of the venting system and damaged
auxiliary fuel tanks may lead to a lower usable fuel quantity,
subsequent fuel starvation and/or fuel spillage into the nacelle.
Actions and Compliance
(f) Unless already done, do the following actions within the
next 30 days after the effective date of this AD:
(1) Inspect and modify the auxiliary fuel tank system following
Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB-
42-032/1, dated January 24, 2007.
(2) Incorporate Doc. No. 7.02.01, Section 05-20-00, page 68a of
Diamond Aircraft DA 42 AMM Temporary Revision AMM-TR-O[Auml]M-42-
056f, dated January 23, 2007, into the Airworthiness Limitations
documents of the FAA-approved maintenance program (e.g., maintenance
manual). The owner/operator holding at least a private pilot
certificate as authorized by section 43.7 of the Federal Aviation
Regulations (14 CFR 43.7) may insert the information specified in
paragraph (f)(2) of this AD into the maintenance program (e.g.,
maintenance manual). Make an entry into the aircraft records showing
compliance with this portion of the AD in accordance with section
43.9 of the Federal Aviation Regulations (14 CFR 43.9).
Note 1: Doc. No. 7.02.01, Section 05-20-00, page 68a of Diamond
Aircraft DA 42 AMM Temporary Revision AMM-TR-O[Auml]M-42-056f, dated
January 23, 2007, specifies additional repetitive inspections for
the auxiliary tank vent system.
