ACTION: Final rule.
AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
PO 00000
Frm 00010

Sfmt 4700
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
It was detected by the STC holder that in
earlier installations of the ACASII system
there were no isolation diodes installed in
the Heading and Attitude Valid lines. The
absence of an isolation diode in the valid
lines can prevent the valid flag to come up
even if a gyro fault exists. The problem has
only been detected for Heading Valid lines
but could equally affect the Attitude Valid
lines.
With installation of the ACASII, the
heading and attitude valid lines have to be
connected to the TPU67A. On valid state, the
signals are +28VDC. On invalid, the signals
are open. This condition of direct connection
(without an isolation diode installed) of the
valid lines to the TPU67A, if not corrected,
could cause the TPU67A to feed current into
the open stated valid lines. This prevents the
flag to appear even if the gyro is invalid,
providing the flight crew with erroneous
navigation information.
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
August 16, 2007.
On August 16, 2007, the Director of
the Federal Register approved the
incorporation by reference of certain
publications listed in this AD.

SUPPLEMENTARY INFORMATION:
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 FAA policies.
Any such differences are highlighted in
a Note within the AD.
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on April 26, 2007 (72 FR
20780). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
The FAA is not aware of any airplanes
on the U.S. Registry that have the
affected equipment installed. All
airplanes with this equipment included
in the applicability of this rule currently
are operated by non-U.S. operators
under foreign registry; therefore, they
are not directly affected by this AD
action at this time. However, the FAA
considers this rule necessary to ensure
that the unsafe condition is addressed in
the event that any of these subject
airplanes are imported and placed on
the U.S. Registry.
Should an affected airplane be
imported and placed on the U.S.
Registry, accomplishment of the
required action will take approximately
8 work-hours at an average labor rate of
$80 per work-hour. Required parts will
cost about $50 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, the total cost
impact of this AD will be $690 per
airplane.
It was detected by the STC holder that in
earlier installations of the ACASII system
there were no isolation diodes installed in
the Heading and Attitude Valid lines. The
absence of an isolation diode in the valid
lines can prevent the valid flag to come up
even if a gyro fault exists. The problem has
only been detected for Heading Valid lines
but could equally affect the Attitude Valid
lines.
With installation of the ACASII, the
heading and attitude valid lines have to be
connected to the TPU67A. On valid state, the
signals are +28VDC. On invalid, the signals
are open. This condition of direct connection
(without an isolation diode installed) of the
valid lines to the TPU67A, if not corrected,
could cause the TPU67A to feed current into
the open stated valid lines. This prevents the
flag to appear even if the gyro is invalid,
providing the flight crew with erroneous
navigation information.
For the reasons stated above, this
Airworthiness Directive (AD) requires the
installation of isolation diodes into the signal
lines to the TPU67A to prevent reverse feed
of the valid lines.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.

Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
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.

Costs of Compliance
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 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 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.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://dms.dot.gov; or in
person at the Docket Management
Facility between 9 a.m. and 5 p.m.,
Monday through Friday, except Federal
holidays. The AD docket contains the
NPRM, the regulatory evaluation, any
comments received, and other
information. The street address for the
Docket Office (telephone (800) 647–

limited to, DORNIER LUFTFAHRT GmbH
Models Dornier 228–100, Dornier 228–101,
Dornier 228–200, Dornier 228–201, and
Dornier 228–212 airplanes that:
(1) Had Supplemental Type Certificate No.
SA1310 installed prior to January 31, 2005;
and
(2) are certificated in any category.
Subject
(d) Air Transport Association of America
(ATA) Code 34: Navigation.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
It was detected by the STC holder that in
earlier installations of the ACASII system
there were no isolation diodes installed in
the Heading and Attitude Valid lines. The
absence of an isolation diode in the valid
lines can prevent the valid flag to come up
even if a gyro fault exists. The problem has
only been detected for Heading Valid lines
but could equally affect the Attitude Valid
lines.
With installation of the ACASII, the
heading and attitude valid lines have to be
connected to the TPU67A. On valid state, the
signals are +28VDC. On invalid, the signals
are open. This condition of direct connection
(without an isolation diode installed) of the
valid lines to the TPU67A, if not corrected,
could cause the TPU67A to feed current into
the open stated valid lines. This prevents the
flag to appear even if the gyro is invalid,
providing the flight crew with erroneous
navigation information.
For the reasons stated above, this
Airworthiness Directive (AD) requires the
installation of isolation diodes into the signal
lines to the TPU67A to prevent reverse feed
of the valid lines.
Actions and Compliance
(f) Unless already done, within the next
100 hours time-in-service (TIS) after August
16, 2007 (the effective date of this AD),
modify the Honeywell CAS67A ACASII

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) issued 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:
It was detected by the STC holder that in earlier installations
of the ACASII system there were no isolation diodes installed in the
Heading and Attitude Valid lines. The absence of an isolation diode
in the valid lines can prevent the valid flag to come up even if a
gyro fault exists. The problem has only been detected for Heading
Valid lines but could equally affect the Attitude Valid lines.
With installation of the ACASII, the heading and attitude valid
lines have to be connected to the TPU67A. On valid state, the
signals are +28VDC. On invalid, the signals are open. This condition
of direct connection (without an isolation diode installed) of the
valid lines to the TPU67A, if not corrected, could cause the TPU67A
to feed current into the open stated valid lines. This prevents the
flag to appear even if the gyro is invalid, providing the flight
crew with erroneous navigation information.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective August 16, 2007.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on April 26, 2007 (72
FR 20780). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
It was detected by the STC holder that in earlier installations
of the ACASII system there were no isolation diodes installed in the
Heading and Attitude Valid lines. The absence of an isolation diode
in the valid lines can prevent the valid flag to come up even if a
gyro fault exists. The problem has only been detected for Heading
Valid lines but could equally affect the Attitude Valid lines.
With installation of the ACASII, the heading and attitude valid
lines have to be connected to the TPU67A. On valid state, the
signals are +28VDC. On invalid, the signals are open. This condition
of direct connection (without an isolation diode installed) of the
valid lines to the TPU67A, if not corrected, could cause the TPU67A
to feed current into the open stated valid lines. This prevents the
flag to appear even if the gyro is invalid, providing the flight
crew with erroneous navigation information.
For the reasons stated above, this Airworthiness Directive (AD)
requires the installation of isolation diodes into the signal lines
to the TPU67A to prevent reverse feed of the valid lines.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
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 FAA policies. Any such differences are
highlighted in a Note within the AD.
Costs of Compliance
The FAA is not aware of any airplanes on the U.S. Registry that
have the affected equipment installed. All airplanes with this
equipment included in the applicability of this rule currently are
operated by non-U.S. operators under foreign registry; therefore, they
are not directly affected by this AD action at this time. However, the
FAA considers this rule necessary to ensure that the unsafe condition
is addressed in the event that any of these subject airplanes are
imported and placed on the U.S. Registry.
Should an affected airplane be imported and placed on the U.S.
Registry, accomplishment of the required action will take approximately
8 work-hours at an average labor rate of $80 per work-hour. Required
parts will cost about $50 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, the total cost impact of this AD will be
$690 per airplane.
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 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 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.
Examining the AD Docket
You may examine the AD docket on the Internet at https://
dms.dot.gov; or in person at the Docket Management Facility between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains the NPRM, the regulatory evaluation, any comments
received, and other information. The street address for the Docket
Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments
will be available in the AD docket shortly after receipt.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2007-14-06 AEROTECHNIC Vertiebs -u. Service GmbH: Amendment 39-
15128; Docket No. FAA-2007-27680; Directorate Identifier 2007-CE-
026-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective August
16, 2007.
[[Page 38002]]
Affected ADs
(b) None.
Applicability
(c) This AD applies to Honeywell CAS67A ACAS II systems that are
installed on, but not limited to, DORNIER LUFTFAHRT GmbH Models
Dornier 228-100, Dornier 228-101, Dornier 228-200, Dornier 228-201,
and Dornier 228-212 airplanes that:
(1) Had Supplemental Type Certificate No. SA1310 installed prior
to January 31, 2005; and
(2) are certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 34:
Navigation.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
It was detected by the STC holder that in earlier installations
of the ACASII system there were no isolation diodes installed in the
Heading and Attitude Valid lines. The absence of an isolation diode
in the valid lines can prevent the valid flag to come up even if a
gyro fault exists. The problem has only been detected for Heading
Valid lines but could equally affect the Attitude Valid lines.
With installation of the ACASII, the heading and attitude valid
lines have to be connected to the TPU67A. On valid state, the
signals are +28VDC. On invalid, the signals are open. This condition
of direct connection (without an isolation diode installed) of the
valid lines to the TPU67A, if not corrected, could cause the TPU67A
to feed current into the open stated valid lines. This prevents the
flag to appear even if the gyro is invalid, providing the flight
crew with erroneous navigation information.
For the reasons stated above, this Airworthiness Directive (AD)
requires the installation of isolation diodes into the signal lines
to the TPU67A to prevent reverse feed of the valid lines.
Actions and Compliance
(f) Unless already done, within the next 100 hours time-in-
service (TIS) after August 16, 2007 (the effective date of this AD),
modify the Honeywell CAS67A ACASII System Installation following
Aerotechnic Vertiebs -u. Service GmbH Service Bulletin No. DO228-
119780-0104, Revision 2, dated December 21, 2006.
