ACTION: Final rule.
AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for certain
Diamond Aircraft Industries GmbH
Models DA 42 NG and DA 42 M–NG
airplanes. This AD results from
mandatory continuing airworthiness
information (MCAI) issued by an
aviation authority of another country to
identify and correct an unsafe condition
PO 00000

Sfmt 4700
During maintenance troubleshooting of the
DA 42 NG alternator indication system it has
been discovered that, with one alternator
inoperative, the system did not give a
warning indication as described in the
Airplane Flight Manual.
Subsequent investigation results showed
that the voltage regulator warning circuit,
E:\FR\FM\03MRR1.SGM
03MRR1
11696
Federal Register / Vol. 79, No. 41 / Monday, March 3, 2014 / Rules and Regulations
which is part of the engine, monitors Bus
Voltage and is the only trigger for the
alternator fail annunciation. As a result, one
alternator may fail but the related voltage
regulator does not trigger the alternator fail
annunciation as the voltage is being held at
the regular level by the second alternator on
board.
The remaining generating system
indication for the pilot is unaffected. The
ampere-meter is indicating a load on each
alternator and in case of a Low Voltage
condition a caution message will be
displayed.
This condition, if not corrected, could lead
to an undetected loss of one engine alternator
and reduced capability of the electrical
generating power system, possibly impairing
safe continuation of the flight.
Prompted by this event, Diamond Aircraft
Industries (DAI) introduced at airframe level
an additional independent alternator fail
caution trigger by using the G1000 amperemeter signals. The trigger is set once an
alternator provides less than 5A and thus
indicates electrical power supply failure to
the ship system.
DAI issued Mandatory Service Bulletin
(MSB) 42NG–003/12 providing instructions
for installation of the Secondary
Configuration Card Part Number (P/N) 010–
12074–02 ‘‘Additional ALTN FAIL trigger’’
with system software P/N 010–00670–10
applicable for all DA 42 NG and DA 42 M–
NG aeroplanes.
In addition, model DA 42 M–NG now
incorporates an output of the GEA 71 to
activate the alternator fail relay. DAI issued
Mandatory Service Bulletin (MSB) 42MNG–
006 to provide instructions for installation of
that additional control cable P/N D62–2510–
97–00–SB.
For the reasons described above, this AD
requires installation of the Secondary
Configuration Card P/N 010–12074–02
‘‘Additional ALTN FAIL trigger’’ and System
Software P/N 010–00670–10 for all DA 42 NG
and DA 42 M–NG aeroplanes and installation
of GEA Alternator fail control cable P/N D62–
2510–97–00–SB on certain model DA 42 M–
NG aeroplanes.
This AD also prohibits installation of
System Software prior to P/N 010–00670–10.

docket on the Internet at: https://

Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM (78
FR 66666, November 6, 2013) or on the
determination of the cost to the public.
Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting the AD
as proposed except for minor editorial
changes. We have determined that these
minor changes:
VerDate Mar<15>2010
16:16 Feb 28, 2014
Jkt 232001
• Are consistent with the intent that
was proposed in the NPRM (78 FR
66666, November 6, 2013) for correcting
the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (78 FR 66666,
November 6, 2013).
Costs of Compliance
We estimate that this AD will affect
26 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 AD. The
average labor rate is $85 per work-hour.
Required parts would cost about $ 115
per product.
Based on these figures, we estimate
the cost of the AD on U.S. operators to
be $7,410, or $285 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 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
the DOT Regulatory Policies and
Procedures (44 FR 11034, February 26,
1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) Will not have a significant
economic impact, positive or negative,

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 certain Diamond Aircraft
Industries GmbH Models DA 42 NG and DA 42 M-NG airplanes. That NPRM was
published in the Federal Register on November 6, 2013 (78 FR 66666).
That NPRM proposed to correct an unsafe condition for the specified
products and was based on mandatory continuing airworthiness
information (MCAI) originated by an aviation authority of another
country. The MCAI states:
During maintenance troubleshooting of the DA 42 NG alternator
indication system it has been discovered that, with one alternator
inoperative, the system did not give a warning indication as
described in the Airplane Flight Manual.
Subsequent investigation results showed that the voltage
regulator warning circuit,
[[Page 11696]]
which is part of the engine, monitors Bus Voltage and is the only
trigger for the alternator fail annunciation. As a result, one
alternator may fail but the related voltage regulator does not
trigger the alternator fail annunciation as the voltage is being
held at the regular level by the second alternator on board.
The remaining generating system indication for the pilot is
unaffected. The ampere-meter is indicating a load on each alternator
and in case of a Low Voltage condition a caution message will be
displayed.
This condition, if not corrected, could lead to an undetected
loss of one engine alternator and reduced capability of the
electrical generating power system, possibly impairing safe
continuation of the flight.
Prompted by this event, Diamond Aircraft Industries (DAI)
introduced at airframe level an additional independent alternator
fail caution trigger by using the G1000 ampere-meter signals. The
trigger is set once an alternator provides less than 5A and thus
indicates electrical power supply failure to the ship system.
DAI issued Mandatory Service Bulletin (MSB) 42NG-003/12
providing instructions for installation of the Secondary
Configuration Card Part Number (P/N) 010-12074-02 ``Additional ALTN
FAIL trigger'' with system software P/N 010-00670-10 applicable for
all DA 42 NG and DA 42 M-NG aeroplanes.
In addition, model DA 42 M-NG now incorporates an output of the
GEA 71 to activate the alternator fail relay. DAI issued Mandatory
Service Bulletin (MSB) 42MNG-006 to provide instructions for
installation of that additional control cable P/N D62-2510-97-00-SB.
For the reasons described above, this AD requires installation
of the Secondary Configuration Card P/N 010-12074-02 ``Additional
ALTN FAIL trigger'' and System Software P/N 010-00670-10 for all DA
42 NG and DA 42 M-NG aeroplanes and installation of GEA Alternator
fail control cable P/N D62-2510-97-00-SB on certain model DA 42 M-NG
aeroplanes.
This AD also prohibits installation of System Software prior to
P/N 010-00670-10.
The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/#!documentDetail;D=FAA-2013-0937-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (78 FR 66666, November 6,
2013) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD as proposed except for minor editorial changes. We have
determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (78 FR 66666, November 6, 2013) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 66666, November 6, 2013).
Costs of Compliance
We estimate that this AD will affect 26 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 AD. The average labor rate
is $85 per work-hour. Required parts would cost about $ 115 per
product.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $7,410, or $285 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 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 the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
