SUPPLEMENTARY INFORMATION:
SUMMARY:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
PO 00000
Frm 00003
Fmt 4700
Sfmt 4700
47529
part 39 to include an AD that would
apply to the specified products. The
NPRM was published in the Federal
Register on April 8, 2013 (78 FR 20844).
The NPRM proposed to correct an
unsafe condition for the specified
products. Transport Canada Civil
Aviation (TCCA), which is the aviation
authority for Canada, has issued
Canadian Airworthiness Directive CF–
2012–26, dated October 30, 2012
(referred to after this as the Mandatory
Continuing Airworthiness Information,
or ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
The CL–600–2B19 aeroplane flap actuator
inboard pinion seal is prone to leak which
can cause internal contamination of the
actuator braking mechanism and subsequent
actuator failure. This condition, if not
corrected, can cause flap system failure. In
certain weather and runway conditions,
frequent flap system failures pose a safety
concern.
To improve the internal actuator sealing, the
flap actuator manufacturer has redesigned
the inboard pinion seal.
Transport Canada Civil Aviation (TCCA) has
been monitoring, through an actuator
sampling program, the performance of the
flap system since the introduction of
actuators equipped with this new inboard
pinion seal. Based on this sampling program
and recent flap reliability data, TCCA is
mandating a restoration task to install the
redesigned flap actuator inboard pinion seal
on all applicable actuators.
The required action is revising the
maintenance program by incorporating
two new airworthiness limitation tasks.
The unsafe condition is flap system
failure, and consequent reduced control
of the airplane. 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
have considered the comment received.
Statement of Support for the NPRM (78
FR 20844, April 8, 2013) and Request
To Shorten Compliance Time
The Airline Pilots Association
International stated it supports the
NPRM (78 FR 20844, April 8, 2013), and
requested that we shorten the
compliance time to ensure that the
identified safety issue is corrected
within the airplane fleet as soon as
possible.
We do not agree with the request to
shorten the compliance time. After
considering all the available
information, we have determined that
the compliance time, as proposed,
represents an appropriate interval of
time in which the required actions can
E:\FR\FM\06AUR1.SGM
06AUR1
47530
Federal Register / Vol. 78, No. 151 / Tuesday, August 6, 2013 / Rules and Regulations
be performed in a timely manner within
the affected fleet, while still maintaining
an adequate level of safety. In
developing an appropriate compliance
time, we considered the safety
implications, parts availability, and
normal maintenance schedules for
timely accomplishment of installing the
inboard pinion seal in the flap actuator.
Further, we arrived at the proposed
initial task compliance time with
operator and manufacturer concurrence.
To reduce the compliance time of the
NPRM (78 FR 20844, April 8, 2013)
would necessitate (under the provisions
of the Administrative Procedure Act)
reissuing the notice, reopening the
period for public comment, considering
additional comments subsequently
received, and eventually issuing a final
rule. We have determined that further
delay of this final rule is not
appropriate. However, if additional data
are presented that would justify a
shorter compliance time, we might
consider further rulemaking on this
issue. We have not changed this AD in
this regard.
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
20844, April 8, 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 20844,
April 8, 2013).
Conclusion
Costs of Compliance
We reviewed the available data,
including the comment received, and
determined that air safety and the
public interest require adopting this AD

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.

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.
The NPRM was published in the Federal Register on April 8, 2013 (78 FR
20844). The NPRM proposed to correct an unsafe condition for the
specified products. Transport Canada Civil Aviation (TCCA), which is
the aviation authority for Canada, has issued Canadian Airworthiness
Directive CF-2012-26, dated October 30, 2012 (referred to after this as
the Mandatory Continuing Airworthiness Information, or ``the MCAI''),
to correct an unsafe condition for the specified products. The MCAI
states:
The CL-600-2B19 aeroplane flap actuator inboard pinion seal is prone
to leak which can cause internal contamination of the actuator
braking mechanism and subsequent actuator failure. This condition,
if not corrected, can cause flap system failure. In certain weather
and runway conditions, frequent flap system failures pose a safety
concern.
To improve the internal actuator sealing, the flap actuator
manufacturer has redesigned the inboard pinion seal.
Transport Canada Civil Aviation (TCCA) has been monitoring, through
an actuator sampling program, the performance of the flap system
since the introduction of actuators equipped with this new inboard
pinion seal. Based on this sampling program and recent flap
reliability data, TCCA is mandating a restoration task to install
the redesigned flap actuator inboard pinion seal on all applicable
actuators.
The required action is revising the maintenance program by
incorporating two new airworthiness limitation tasks. The unsafe
condition is flap system failure, and consequent reduced control of the
airplane. You may obtain further information by examining the MCAI in

compliance time, we considered the safety implications, parts
availability, and normal maintenance schedules for timely
accomplishment of installing the inboard pinion seal in the flap
actuator. Further, we arrived at the proposed initial task compliance
time with operator and manufacturer concurrence.
To reduce the compliance time of the NPRM (78 FR 20844, April 8,
2013) would necessitate (under the provisions of the Administrative
Procedure Act) reissuing the notice, reopening the period for public
comment, considering additional comments subsequently received, and
eventually issuing a final rule. We have determined that further delay
of this final rule is not appropriate. However, if additional data are
presented that would justify a shorter compliance time, we might
consider further rulemaking on this issue. We have not changed this AD
in this regard.
Conclusion
We reviewed the available data, including the comment received, and
determined that air safety and the public interest require adopting
this 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 20844, April 8, 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 20844, April 8, 2013).
Costs of Compliance
We estimate that this AD affects 573 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

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.
