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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (79 FR 41145, July 15, 2014) for correcting the unsafe condition; 
and
    <bullet> 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.

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.
