ACTION: Final Rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for certain
Bombardier, Inc. Model DHC–8–400
series airplanes. This AD was prompted
by reports of chafing found on the main
landing gear (MLG) yoke. The chafing
was attributed to contact between the
nacelle fire detection wires and the
MLG yoke. This AD requires inspections
of the nacelle fire detection wires and
the MLG yoke for damage; replacing
nacelle fire detection wires, if necessary;
repairing the MLG yoke, if necessary;
and installing brackets and associated
hardware to secure the fire detection
wires. We are issuing this AD to prevent
chafing between the nacelle fire
detection wires and the MLG yoke.
Chafing could lead to cracking and
subsequent failure of the MLG yoke,
which could adversely affect the safe
landing of the airplane. In addition,
chafing of the nacelle fire detection
wires could cause them to fail and
prevent the detection of a fire in the
nacelle assembly.

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 November 5, 2012 (77 FR
66413). That NPRM proposed to correct
an unsafe condition for the specified
products. The Mandatory Continuing
Airworthiness Information (MCAI)
states:
tkelley on DSK3SPTVN1PROD with RULES
There have been two (2) in-service reports of
chafing found on the main landing gear
(MLG) yoke. The chafing was attributed to
contact between the nacelle fire detection
wire and the MLG yoke. This chafing may
lead to cracking and subsequent failure of the
MLG yoke.
Failure of the MLG yoke could adversely
affect the safe landing of the aeroplane. In
addition, failure of the fire detection wire
could prevent the detection of a fire in the
nacelle assembly.
This [Canadian] Airworthiness Directive
(AD) mandates the [detailed] inspection of
the nacelle fire detection wires and [detailed
inspection of the] MLG yoke for damage
[chafing, nicks, cracking] and the installation
of new brackets to secure the fire detection
wire to prevent chafing against the MLG yoke
[and corrective actions if necessary].
Corrective actions include replacing
damaged wires with new wires and
repairing the MLG yoke. You may
obtain further information by examining
the MCAI in the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received.
VerDate Mar<15>2010

Jkt 229001
Request To Allow Reference to
Canadian AD
Horizon Air requested that the last
sentence in paragraph (g)(2)(ii) of the
NPRM (77 FR 66413, November 5, 2012)
be deleted. That sentence states, ‘‘The
approved repair must specifically
reference this AD.’’ Horizon Air stated
that Bombardier references Transport
Canada Civil Aviation ADs on repair
drawings and the requirement to
reference an FAA AD has not been
included in previous ADs issued by the
FAA. Horizon noted that a reference to
the Canadian AD should be sufficient
and the final rule should be changed to
allow a reference to the Canadian AD.
For the reasons presented by the
commenter we agree to delete the last
sentence of paragraph (g)(2)(ii) in this
AD. That sentence was inadvertently
included in the NPRM (77 FR 66413,
November 5, 2012).
Request To Change Certain Reference to
Brackets
Horizon Air requested that paragraph
(g)(3) of the NPRM (77 FR 66413,
November 5, 2012) be revised to delete
the word ‘‘new’’ from the sentence,
‘‘Install new brackets and associated
hardware . . . .’’ Horizon acknowledged
that this sentence was included in
Canadian AD CF–2012–15, dated April
30, 2012, which is referenced in the
NPRM, but based on the FAA’s policy
of strict interpretation of the word
‘‘new’’ as a zero-time part, this sentence
places an additional requirement on
U.S. operators to ensure that only zerotime brackets are installed.
We agree to revise paragraph (g)(3) in
this final rule to delete the word ‘‘new.’’
This will remove the requirement that
operators only install ‘‘new’’ brackets.
We also deleted the word ‘‘new’’ in the
SUMMARY section of this final rule.
Conclusion
We reviewed the available data,
including the comments received, and
determined that air safety and the
public interest require adopting the AD
with the changes described previously
and minor editorial changes. We have
determined that these changes:
• Are consistent with the intent that
was proposed in the NPRM (77 FR
66413, November 5, 2012) for correcting
the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (77 FR 66413,
November 5, 2012).
Costs of Compliance
We estimate that this AD will affect
80 products of U.S. registry. We also
estimate that it will take about 3 work-
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
hours per product to comply with the
basic requirements of this AD. The
average labor rate is $85 per work-hour.
Required parts will cost about $332 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 parts. 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 this AD
to the U.S. operators to be $46,960, or
$587 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 that 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

FR 66413). That NPRM proposed to correct an unsafe condition for the
specified products. The Mandatory Continuing Airworthiness Information
(MCAI) states:
There have been two (2) in-service reports of chafing found on the
main landing gear (MLG) yoke. The chafing was attributed to contact
between the nacelle fire detection wire and the MLG yoke. This
chafing may lead to cracking and subsequent failure of the MLG yoke.
Failure of the MLG yoke could adversely affect the safe landing of
the aeroplane. In addition, failure of the fire detection wire could
prevent the detection of a fire in the nacelle assembly.
This [Canadian] Airworthiness Directive (AD) mandates the [detailed]
inspection of the nacelle fire detection wires and [detailed
inspection of the] MLG yoke for damage [chafing, nicks, cracking]
and the installation of new brackets to secure the fire detection
wire to prevent chafing against the MLG yoke [and corrective actions
if necessary].
Corrective actions include replacing damaged wires with new wires and
repairing the MLG yoke. You may obtain further information by examining
the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received.
Request To Allow Reference to Canadian AD
Horizon Air requested that the last sentence in paragraph
(g)(2)(ii) of the NPRM (77 FR 66413, November 5, 2012) be deleted. That
sentence states, ``The approved repair must specifically reference this
AD.'' Horizon Air stated that Bombardier references Transport Canada
Civil Aviation ADs on repair drawings and the requirement to reference
an FAA AD has not been included in previous ADs issued by the FAA.
Horizon noted that a reference to the Canadian AD should be sufficient
and the final rule should be changed to allow a reference to the
Canadian AD.
For the reasons presented by the commenter we agree to delete the
last sentence of paragraph (g)(2)(ii) in this AD. That sentence was
inadvertently included in the NPRM (77 FR 66413, November 5, 2012).
Request To Change Certain Reference to Brackets
Horizon Air requested that paragraph (g)(3) of the NPRM (77 FR
66413, November 5, 2012) be revised to delete the word ``new'' from the
sentence, ``Install new brackets and associated hardware . . . .''
Horizon acknowledged that this sentence was included in Canadian AD CF-
2012-15, dated April 30, 2012, which is referenced in the NPRM, but
based on the FAA's policy of strict interpretation of the word ``new''
as a zero-time part, this sentence places an additional requirement on
U.S. operators to ensure that only zero-time brackets are installed.
We agree to revise paragraph (g)(3) in this final rule to delete
the word ``new.'' This will remove the requirement that operators only
install ``new'' brackets. We also deleted the word ``new'' in the
SUMMARY section of this final rule.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously and minor editorial
changes. We have determined that these changes:
Are consistent with the intent that was proposed in the
NPRM (77 FR 66413, November 5, 2012) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 66413, November 5, 2012).
Costs of Compliance
We estimate that this AD will affect 80 products of U.S. registry.
We also estimate that it will take about 3 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost about $332 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 parts. 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 this AD to the U.S. operators
to be $46,960, or $587 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 that 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
