14 CFR Part 39

[Docket No. FAA-2014-0567; Directorate Identifier 2014-NM-124-AD; 
Amendment 39-18043; AD 2014-25-02]
RIN 2120-AA64

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 
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) 
airplanes. This AD was prompted by issuance of revised certification 
maintenance requirements for the horizontal stabilizer trim actuator 
(HSTA). This AD requires revising the maintenance or inspection 
program. We are issuing this AD to detect and correct premature wear 
and cracking of the HSTAs, which could result in reduced structural 
integrity and reduced control of the airplane due to the failure of 
system components.

DATES: This AD becomes effective January 16, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 16, 
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-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM 
published in the Federal Register on August 14, 2014 (79 FR 47594).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-13, dated April 17, 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-600-2B19 
(Regional Jet Series 100 & 440) airplanes. The MCAI states:

    A revision has been made to Part 2 of the Canadair Regional Jet 
Maintenance Requirements Manual (MRM), Appendix A--Certification 
Maintenance Requirements [CMR] which introduces a new task for the 
HSTA. Failure to comply with the CMR task could lead to an unsafe 
condition.
    This [Canadian] AD is issued to ensure that premature wear and 
cracking of the affected components are detected and corrected. 
[This condition could result in reduced structural integrity and 
reduced control of the airplane due to the failure of system 
components.]

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0567-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 47594, August 14, 
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 47594, August 14, 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 47594, August 14, 2014).

Costs of Compliance

    We estimate that this AD affects 416 airplanes of U.S. registry.
    We also estimate that it will take about 1 work-hour 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 $0 per product. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $35,360, or $85 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:

[[Page 73813]]

    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.

of Bombardier TR 2A-58, dated January 31, 2014, into Appendix A--
CMR, of Part 2 of the Bombardier CL-600-2B19 MRM. When Bombardier TR 
2A-58, dated January 31, 2014, has been included in the general 
revisions of the Bombardier CL-600-2B19 MRM, the general revisions 
may be inserted into the MRM, provided the relevant information in 
the general revision is identical to that in Bombardier TR 2A-58, 
dated January 31, 2014.

(h) No Alternative Actions and Intervals

    After accomplishing the revision required by paragraph (g) of 
this AD, no alternative actions (e.g., inspections) or intervals may 
be used unless the actions or intervals are approved as an 
alternative method of compliance (AMOC) in accordance with the 
procedures specified in paragraph (i)(1) of this AD.

(i) Other FAA AD Provisions
