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 E:\FR\FM\10FER1.SGM 10FER1 Federal Register / Vol. 80, No. 27 / Tuesday, February 10, 2015 / Rules and Regulations 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 https:// www.regulations.gov/ #!documentDetail;D=FAA-2014-07500002. 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: • Are consistent with the intent that was proposed in the NPRM (79 FR 59459, October 2, 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 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. rljohnson on DSK3VPTVN1PROD with RULES 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 VerDate Sep<11>2014 15:13 Feb 09, 2015 Jkt 235001 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.

SUPPLEMENTARY INFORMATION: Discussion On July 16, 2014, at 79 FR 41464, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Agusta Model AB139 and AW139 helicopters with a flexible hydraulic hose, part number (P/N) A494AE2E00E0670X, A494AE3E00E0424X, A494AE3E00E0530X, A494AE3E00E0570X, A494AE3E00E0580X, A494AE3E00E0620X, A494AE3E00E0930X, A494AE6E14E0348X, or A494AE6E21E0330X, installed. The NPRM proposed to require replacing these single-braided flexible hydraulic hoses with double-braided flexible hydraulic hoses. The proposed requirements were intended to prevent loss of hydraulic power and subsequent loss of helicopter control. The NPRM was prompted by AD No. AD No. 2013–0177, dated August 8, 2013, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Agusta Model AB139 and AW139 helicopters. EASA advises that leaking hydraulic system flexible hoses have been reported on inservice helicopters. An investigation indicated that single braided flexible hydraulic hoses, which are part of the original design for Model AB139 and AW139 helicopters, may not be strong enough to cope with the hydraulic system pressure over long periods. If not corrected, this condition could lead to other hydraulic system leaks, possibly resulting in loss of hydraulic power and reduced control of the helicopter, EASA E:\FR\FM\10FER1.SGM 10FER1

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 https://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:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 59459, October 2, 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 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

    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.
