Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is 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 a report that a fouling 
condition was found between the generator power cables and the support 
brackets of the auxiliary-aft fuel tank during production. This AD 
requires a visual inspection of the generator power cables for damage, 
installation of protective conduits and edging grommets, and applicable 
corrective actions. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective April 2, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 2, 
2020.

SUPPLEMENTARY INFORMATION: 

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-22, dated May 27, 
2019

[[Page 11285]]

(``Canadian AD CF-2019-22'') (also referred to 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. You may examine the MCAI in 
the AD docket on the internet at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2019-0877.
    The FAA 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 December 2, 2019 (84 FR 
65935). The NPRM was prompted by a report that a fouling condition was 
found between the generator power cables and the support brackets of 
the auxiliary-aft fuel tank during production. The NPRM proposed to 
require a visual inspection of the generator power cables for damage, 
installation of protective conduits and edging grommets, and applicable 
corrective actions. The FAA is issuing this AD to address damage to the 
insulation sleeve of the generator power cables that can potentially 
cause a short circuit, arcing, and a malfunction of one or both main 
generators. See the MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor editorial changes. The FAA has determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Service Bulletin 601R-24-131, dated June 28, 
2012. This service information describes procedures for visual 
inspection of the generator power cables for damage, installation of 
protective insulation and edging grommets, and applicable corrective 
actions. Corrective actions include repair. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 9 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
22 work-hours x $85 per hour = $1,870........................            $524           $2,394          $21,546
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data that would enable the 
agency 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.
    The FAA is 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

    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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
