Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
[[Page 5903]]
Bombardier, Inc. Model CL-215-6B11 (CL-215T Variant), and CL-215-6B11
(CL-415 Variant) airplanes. This AD was prompted by a report that,
during a routine inspection, corrosion was discovered on the lower
bearing of the rudder upper torque tube. This AD requires applying
grease to the bearing; doing a general visual inspection of the
expelled old grease for any contaminants, metal wear, and indication of
corrosion, and replacing the bearing if necessary; and revising the
maintenance or inspection program, as applicable, to incorporate the
rudder spring tab operational test and a check of the rudder spring tab
operation into the daily inspection. We are issuing this AD to prevent
corroded bearings, which could result in a partial or total loss of
axial support.
DATES: This AD becomes effective March 11, 2015.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of March 11,
2015.

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-215-6B11 (CL-215T Variant), and CL-215-6B11 (CL-415 Variant)
airplanes. The NPRM published in the Federal Register on July 15, 2014
(79 FR 41145).
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-08, dated March 12, 2013 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Bombardier, Inc. Model CL-215-6B11 (CL-
215T Variant), and CL-215-6B11 (CL-415 Variant) airplanes. The MCAI
states:
During a routine inspection, corrosion was discovered on the
Rudder Upper Torque Tube Lower bearing, part number (P/N) DAT48-64A.
Corroded bearings may eventually result in a partial or total loss
of axial support.
As such, Bombardier has issued Service Bulletin (SB) 215-A3171
Rev. 1 and SB 215-A4452 Rev. 1, which provide instructions to
refresh the lubrication in the bearing in order to inspect for
corrosion and/or contaminants in the existing grease. These SBs will
also incorporate an operational check to the 50 hour maintenance
scheduled tasks, and a test of the Rudder Spring Tab operation into
the Daily inspection or the aircrew Preflight Check.
Required actions include applying grease to the bearing, doing a
general visual inspection of the expelled old grease for any
contaminants, metal wear, and indication of corrosion, and replacing
the bearing if necessary; revising the maintenance or inspection
program, as applicable, to incorporate the rudder spring tab
operational test; and revising the maintenance or inspection program,
as applicable, to incorporate a check of the rudder spring tab
operation into the daily inspection. You may examine the MCAI in the AD
docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0446-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 41145, July 15,
2014) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data 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 (79 FR 41145, July 15, 2014) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 41145, July 15, 2014).
Related Service Information
Bombardier, Inc. has issued Bombardier Alert Service Bulletin 215-
A3171, Revision 1, dated January 25, 2012, and Bombardier Alert Service
Bulletin 215-A4452, Revision 1, dated January 3, 2012. This service
information describes applying grease to the bearing; doing a general
visual inspection of the expelled old grease for any contaminants,
metal wear, and indication of corrosion, and replacing the bearing if
necessary; and revising the maintenance or inspection program, as
applicable, to incorporate the rudder spring tab operational test and a
check of the rudder spring tab operation into the daily inspection. You
can find this information at http://www.regulations.gov by searching
for and locating Docket No. FAA-2014-0446.
Costs of Compliance
We estimate that this AD affects 5 airplanes of U.S. registry.
We also estimate that it will 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 will be negligible. Based on
these figures, we estimate the cost of this AD on U.S. operators to be
$850, or $170 per product.
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in 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.
[[Page 5904]]
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.
