SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Bombardier, Inc. Model
CL–600–2C10 (Regional Jet Series 700,
701, & 702) airplanes. The NPRM
published in the Federal Register on
June 30, 2015 (80 FR 37200). The NPRM
was prompted by reports of cracked
forward door members of the inboard
MLG doors. The NPRM proposed to
require repetitive inspections of the
inboard MLG doors, repairs if necessary,
and replacement of the inboard MLG
doors. The NPRM also proposed
optional terminating action for the door
replacement. We are issuing this AD to
prevent loss of an MLG door during
flight, which could result in damage to
the airplane.

Federal Register / Vol. 81, No. 13 / Thursday, January 21, 2016 / Rules and Regulations
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2014–42,
dated December 12, 2014 (referred to
after this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc. Model CL–
600–2C10 (Regional Jet Series 700, 701,
& 702) airplanes. The MCAI states:
Cases of inboard MLG doors with cracked
door forward members were found. A
cracked inboard MLG door forward member
could result in door departure from the
aeroplane. Loss of an MLG door during flight
could result in damage to the aeroplane and
injury to persons on the ground.
This [Canadian] AD mandates the
repetitive inspection [and corrective actions
if necessary] and replacement of the inboard
MLG doors.
The repetitive inspection is a detailed
inspection for damage (including
deformation, pulled or missing fasteners
on the inner skins and outer skin, and
cracks) on the inner skins, outer skin,
and the forward member of the inboard
MLG doors. Corrective actions include
repairing, removing, or replacing the
inboard MLG door.
You may examine the MCAI in the
AD docket on the Internet at https://
www.regulations.gov/#!document
Detail;D=FAA-2015-1987-0002.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comment
received on the NPRM (80 FR 37200,
June 30, 2015) and the FAA’s response
to the comment.
jstallworth on DSK7TPTVN1PROD with RULES
Request To Revise Repair Instructions
Envoy Airlines requested that we
revise the wording in paragraph
(i)(1)(ii)(A) of the proposed AD (80 FR
37200, June 30, 2015) to clarify that
removal of the MLG door is not required
in all repair situations. Envoy Airlines
stated that Bombardier Service Bulletin
670BA–32–042, Revision A, dated July
2, 2014, including Appendixes A and B,
both dated November 5, 2013, specifies
that repairs can be accomplished with
the door installed in some situations.
Envoy Airlines suggested that the text
‘‘Repair and reinstall the door’’ in
paragraph (i)(1)(ii)(A) of the proposed
AD be reworded to specify ‘‘repair the
door.’’
We agree with the commenter’s
request to revise the repair instructions.
We have revised paragraph (i)(1)(ii)(A)
of this AD by removing the instructions
to reinstall the door.
VerDate Sep<11>2014
15:08 Jan 20, 2016
Jkt 238001
Clarification of Actions
We have clarified the inspection area
in paragraph (g) of this AD by specifying
to inspect for damage on the inner skins,
outer skin, and the forward member of
the inboard MLG doors.
Paragraph (i)(1)(ii)(A) of the proposed
AD (80 FR 37200, June 30, 2015)
specifies to do a repair ‘‘if repair of the
inboard MLG is possible.’’ We have
revised paragraph (i)(1)(ii)(A) of this AD
to clarify the repair is done if it is
possible to repair the inboard MLG door
in accordance with the Accomplishment
Instructions of Bombardier Service
Bulletin 670BA–32–042, Revision A,
dated July 2, 2014, including
Appendixes A and B, both dated
November 5, 2013.
We have also revised paragraph
(i)(1)(i) of this AD to specify that clarify
that removed damaged doors cannot be
reinstalled, unless the door is repaired
prior to reinstallation and the actions
specified in paragraph (l) of this AD are
done.
We have also clarified the actions
required by paragraphs (i)(1)(iii), (i)(2),
(k)(1), and (k)(2)(i) of this AD by
specifying that where Bombardier
Service Bulletin 670BA–32–043,
Revision A, dated November 13, 2014,
specifies to contact the manufacturer for
certain instructions, this AD requires
accomplishing those actions using a
method approved by the Manager, New
York ACO, ANE–170, FAA; or TCCA; or
Bombardier, Inc.’s TCCA DAO.
We have also revised paragraph (m) of
this AD to refer to the latest revision of
Bombardier Service Bulletin 670BA–32–
043, dated July 2, 2014. The ‘‘Pre SB
Part Number’’ column of Section M,
Relationship Chart, of Bombardier
Service Bulletin 670BA–32–043,
Revision A, dated November 13, 2014,
is the same as that in Bombardier
Service Bulletin 670BA–32–043, dated
July 2, 2014.
Conclusion
We reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting this AD
with the changes described previously
and minor editorial changes. We have
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM (80 FR
37200, June 30, 2015) for correcting the
unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (80 FR 37200,
June 30, 2015).
We also determined that these
changes will not increase the economic
PO 00000

burden on any operator or increase the
scope of this AD.

this AD.
Costs of Compliance
We estimate that this AD affects 269
airplanes of U.S. registry.
We estimate that it will take about 16
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 $31,000
per product. Based on these figures, we
estimate the cost of this AD on U.S.
operators to be $8,704,840, or $32,360
per product.
E:\FR\FM\21JAR1.SGM
21JAR1
Federal Register / Vol. 81, No. 13 / Thursday, January 21, 2016 / Rules and Regulations
In addition, we estimate that any
necessary follow-on actions will take up
to 44 work-hours and require parts
costing up to $31,000, for a cost of up
to $34,740 per product. We have no way
of determining the number of aircraft
that might need these actions.
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.

Discussion
We are adopting a new
airworthiness directive (AD) for all
Airbus Model A310 and Airbus Model
A300 B4–600, B4–600R, and F4–600R
series airplanes; and Model A300 C4–
605R Variant F airplanes (collectively
called Model A300–600 series
airplanes). This AD was prompted by a
report of skin disbonding and damage
found on the composite side panel of
the rudder, located between the rudder
core and skin of a previously repaired
area. This AD requires an inspection for
disbonding or damage of certain
rudders, and related investigative
actions and corrective actions if
necessary. We are issuing this AD to
detect and correct disbonding and
damage of the rudder, which could
result in reduced structural integrity of
the rudder and consequent reduced
controllability of the airplane.
DATES: This AD is effective February 25,
2016.

We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Airbus Model A310 and
Airbus Model A300 B4–600, B4–600R,
and F4–600R series airplanes, and
Model A300 C4–605R Variant F
airplanes (collectively called Model
A300–600 series airplanes) series
airplanes. The NPRM published in the
Federal Register on January 23, 2015
(80 FR 3525).
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA Airworthiness
Directive 2014–0026, dated January 28,
2014 (referred to after this as the
Mandatory Continuing Airworthiness
Information, or ‘‘the MCAI’’), to correct
an unsafe condition for all Airbus
Model A310 and Airbus Model A300
B4–600, B4–600R, and F4–600R series
airplanes; and Model A300 C4–605R
Variant F airplanes (collectively called
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
3301
Model A300–600 series airplanes). The
MCAI states:
A case of skin disbonding was reported on
a composite side of a rudder installed on an
A310 aeroplane.
The investigation results revealed that this
disbonding started from a skin panel area
previously repaired in-service in accordance
with the Structural Repair Manual (SRM).
The initial damage has been identified as
a disbonding between the core and the
repaired area. This damage may not be
visually detectable and likely propagates
during normal operation due to the variation
of pressure during ground-air-ground cycles.
This condition, if not detected and
corrected, could affect the structural integrity
of the rudder, possibly resulting in reduced
control of the aeroplane.
For the reasons described above, this
[EASA] AD requires a one-time
thermography inspection of each repaired
rudder or rudder whose maintenance records
are incomplete and, depending on findings,
accomplishment of applicable corrective and
follow-up actions.
Related investigative actions include
doing a pulse thermography inspection
for disbonding or damage of the leftand right-hand rudder side shells; a core
ventilation through the inner skin, an
elasticity laminate checker or ultrasonic
inspection around the identified repairs
in the booster area, and around
identified fluid ingress; and a Tap test
inspection of the glass fiber reinforced
plastic area to identify skin-to-core
disbonding and on identified repairs.
Corrective actions include repairing or
replacing any disbonded or damaged
rudder.
Depending on configuration and
inspection results, the repetitive
inspection intervals are 750 or 1,000
flight cycles, or 500 flight hours or 4
months, whichever occurs later.
You may examine the MCAI in the
AD docket on the Internet at https://

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Bombardier, Inc.
Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes. The
NPRM published in the Federal Register on June 30, 2015 (80 FR 37200).
The NPRM was prompted by reports of cracked forward door members of the
inboard MLG doors. The NPRM proposed to require repetitive inspections
of the inboard MLG doors, repairs if necessary, and replacement of the
inboard MLG doors. The NPRM also proposed optional terminating action
for the door replacement. We are issuing this AD to prevent loss of an
MLG door during flight, which could result in damage to the airplane.
[[Page 3298]]
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-42, dated December 12, 2014 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for certain Bombardier, Inc. Model CL-600-
2C10 (Regional Jet Series 700, 701, & 702) airplanes. The MCAI states:
Cases of inboard MLG doors with cracked door forward members
were found. A cracked inboard MLG door forward member could result
in door departure from the aeroplane. Loss of an MLG door during
flight could result in damage to the aeroplane and injury to persons
on the ground.
This [Canadian] AD mandates the repetitive inspection [and
corrective actions if necessary] and replacement of the inboard MLG
doors.
The repetitive inspection is a detailed inspection for damage
(including deformation, pulled or missing fasteners on the inner skins
and outer skin, and cracks) on the inner skins, outer skin, and the
forward member of the inboard MLG doors. Corrective actions include
repairing, removing, or replacing the inboard MLG door.
You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2015-1987-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comment received on the NPRM (80 FR
37200, June 30, 2015) and the FAA's response to the comment.
Request To Revise Repair Instructions
Envoy Airlines requested that we revise the wording in paragraph
(i)(1)(ii)(A) of the proposed AD (80 FR 37200, June 30, 2015) to
clarify that removal of the MLG door is not required in all repair
situations. Envoy Airlines stated that Bombardier Service Bulletin
670BA-32-042, Revision A, dated July 2, 2014, including Appendixes A
and B, both dated November 5, 2013, specifies that repairs can be
accomplished with the door installed in some situations. Envoy Airlines
suggested that the text ``Repair and reinstall the door'' in paragraph
(i)(1)(ii)(A) of the proposed AD be reworded to specify ``repair the
door.''
We agree with the commenter's request to revise the repair
instructions. We have revised paragraph (i)(1)(ii)(A) of this AD by
removing the instructions to reinstall the door.
Clarification of Actions
We have clarified the inspection area in paragraph (g) of this AD
by specifying to inspect for damage on the inner skins, outer skin, and
the forward member of the inboard MLG doors.
Paragraph (i)(1)(ii)(A) of the proposed AD (80 FR 37200, June 30,
2015) specifies to do a repair ``if repair of the inboard MLG is
possible.'' We have revised paragraph (i)(1)(ii)(A) of this AD to
clarify the repair is done if it is possible to repair the inboard MLG
door in accordance with the Accomplishment Instructions of Bombardier
Service Bulletin 670BA-32-042, Revision A, dated July 2, 2014,
including Appendixes A and B, both dated November 5, 2013.
We have also revised paragraph (i)(1)(i) of this AD to specify that
clarify that removed damaged doors cannot be reinstalled, unless the
door is repaired prior to reinstallation and the actions specified in
paragraph (l) of this AD are done.
We have also clarified the actions required by paragraphs
(i)(1)(iii), (i)(2), (k)(1), and (k)(2)(i) of this AD by specifying
that where Bombardier Service Bulletin 670BA-32-043, Revision A, dated
November 13, 2014, specifies to contact the manufacturer for certain
instructions, this AD requires accomplishing those actions using a
method approved by the Manager, New York ACO, ANE-170, FAA; or TCCA; or
Bombardier, Inc.'s TCCA DAO.
We have also revised paragraph (m) of this AD to refer to the
latest revision of Bombardier Service Bulletin 670BA-32-043, dated July
2, 2014. The ``Pre SB Part Number'' column of Section M, Relationship
Chart, of Bombardier Service Bulletin 670BA-32-043, Revision A, dated
November 13, 2014, is the same as that in Bombardier Service Bulletin
670BA-32-043, dated July 2, 2014.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting
this AD with the changes described previously and minor editorial
changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (80 FR 37200, June 30, 2015) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (80 FR 37200, June 30, 2015).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information.
Bombardier Modification Summary Package IS670528200033,
Revision A-2, dated October 11, 2005. This service information
describes procedures for enlarging the forward and aft hinge cutouts of
the MLG inboard and outboard doors.
Bombardier Service Bulletin 670BA-32-040, Revision D,
dated July 2, 2014, including Appendix A, Revision A, dated July 2,
2014, and Appendix B, Revision B, dated July 2, 2014. This service
information describes procedures for increasing the clearances between
the MLG fairing and the MLG doors.
Bombardier Service Bulletin 670BA-32-040, Revision E,
dated November 13, 2014, including Appendix A, Revision A, dated July
2, 2014, and Appendix B, Revision B, dated July 2, 2014. This service
information describes procedures for increasing the clearances between
the MLG fairing and the MLG doors, and for enlarging the forward and
aft hinge cutouts of the MLG inboard and outboard doors.
Bombardier Service Bulletin 670BA-32-042, Revision A,
dated July 2, 2014, including Appendixes A and B, both dated November
5, 2013. This service information describes procedures for inspecting
and repairing the inboard MLG door inner skins, outer skin, and the
forward member.
Bombardier Service Bulletin 670BA-32-043, dated July 2,
2014; and Bombardier Service Bulletin 670BA-32-043, Revision A, dated
November 13, 2014. This service information describes procedures for
replacing the inboard MLG doors.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section of this
AD.
Costs of Compliance
We estimate that this AD affects 269 airplanes of U.S. registry.
We estimate that it will take about 16 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 $31,000 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $8,704,840, or $32,360 per product.
[[Page 3299]]
In addition, we estimate that any necessary follow-on actions will
take up to 44 work-hours and require parts costing up to $31,000, for a
cost of up to $34,740 per product. We have no way of determining the
number of aircraft that might need these actions.
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);
