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 all 
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) 
airplanes. This AD was prompted by reports of dislodged engine fan cowl 
panels. This AD requires installing additional attaching hardware on 
the left and right fan cowl access panels and the nacelle attaching 
structures. We are issuing this AD to prevent damage to the fuselage 
and flight control surfaces from dislodged engine fan cowl panels.

DATES: This AD becomes effective March 17, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 17, 
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 all Bombardier, Inc. Model 
CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM 
published in the Federal Register on October 2, 2014 (79 FR 59459).
    Transport Canada Civil Aviation (TCCA), which is the airworthiness 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-20, dated July 9, 2014 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition. The MCAI states:

    There have been a number of engine fan cowl panel dislodgement 
incidents reported on the Bombardier CL-600-2B19 aeroplane fleet. 
The dislodged panels may cause damage to the fuselage and flight 
control surfaces of the aeroplane. Also, the debris from a dislodged 
panel may result in runway contamination and has the potential of 
causing injury on the ground.
    Although the majority of the subject panel dislodgements were 
reported on the first or second flight after an engine maintenance 
task was performed that required removal and reinstallation of the 
subject panels, the frequency of the dislodgements indicates that 
the existing attachment design is prone to human (maintenance) 
error.
    Bombardier has attempted to mitigate this issue by issuing 
maintenance advisories emphasizing the proper installation of engine 
fan cowl panels. In order to further mitigate the potential safety 
hazard of the subject panel dislodgement, Bombardier has issued

[[Page 7299]]

Service Bulletin (SB) 601R-71-034 to install additional fasteners 
for the attachment of the engine fan cowl panels to the nacelle's 
structure.
    This [Canadian] AD is issued to mandate compliance with 
Bombardier SB 601R-71-034.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0750-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 59459, October 2, 
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 59459, October 2, 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 59459, October 2, 2014).
    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

    We reviewed Bombardier Service Bulletin 601R-71-034, Revision B, 
dated August 1, 2014. The service information describes procedures for 
installing additional attaching hardware on the left and right fan cowl 
access panels and the nacelle attaching structures. This service 
information is reasonably available; see ADDRESSES for ways to access 
this service information.

Costs of Compliance

    We estimate that this AD affects 518 airplanes of U.S. registry.
    We also estimate that it will take about 9 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 $5,248 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $3,114,734, or $6,013 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:
    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.
