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 BD-700-1A10 and BD-700-1A11 airplanes. This AD 
was prompted by reports of drainage holes on the belly fairing forward 
and middle access panels being obstructed with sealant. This AD 
requires inspecting for and removing all sealant blocking the drainage 
holes on the belly fairing forward and middle access panels. We are 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective January 15, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 15, 
2019.

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 BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the 
Federal Register on September 18, 2018 (83 FR 47113). The NPRM was 
prompted by reports of drainage holes on the belly fairing forward and 
middle access panels being obstructed with sealant. The NPRM proposed 
to require inspecting for and removing all sealant blocking the 
drainage holes on the belly fairing forward and middle access panels.
    We are issuing this AD to address fluid leakage that could lead to 
the accumulation of flammable fluids/vapors, beyond the design capacity 
of the belly fairing venting provisions, which could ignite if an 
ignition source (i.e., spark, static discharge, heat, etc.) is present.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2018-14, dated May 1, 2018 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc., Model BD-700-1A10 and 
BD-700-1A11 airplanes. The MCAI states:

    Bombardier Aerospace (BA) has informed Transport Canada that the 
drainage holes on the belly fairing forward and middle access panels 
may be obstructed with sealant. The purpose of the drainage holes is 
to allow for drainage of a limited quantity of fluids due to any 
leaks, should they occur. This condition, if not corrected, may 
prevent the timely detection of fluid leakage that could lead to the 
accumulation of flammable fluids/vapors, beyond the design capacity 
of the belly fairing venting provisions [which could ignite if an 
ignition source (i.e., spark, static discharge, heat, etc.) is 
present].
    This [Canadian] AD is issued to mandate the removal of all 
sealant blocking the drainage holes on the belly fairing forward and 
middle access panels.

    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0796.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM 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 final rule 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 for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

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) 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.

fairing forward and middle access panels being obstructed with 
sealant. We are issuing this AD to address fluid leakage that could 
lead to the accumulation of flammable fluids/vapors, beyond the 
design capacity of the belly fairing venting provisions, which could 
ignite if an ignition source (i.e., spark, static discharge, heat, 
etc.) is present.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Sealant Removal

    Within 375 flight hours or 12 months, whichever occurs first, 
after the effective date of this AD, do a general visual inspection 
for and remove all sealant blocking the drainage holes on the belly 
fairing forward and middle access panels, in accordance with the 
Accomplishment Instructions of the applicable service information 
listed in figure 1 to paragraph (g) of this AD.
