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 fluid entry and accumulation in the aft 
equipment bay. This AD requires modifying the aft equipment bay. We are 
issuing this AD to prevent excessive quantities of flammable fluid 
accumulation in the aft equipment bay. Flammable fluid entry and 
accumulation in the aft equipment bay, in excessive quantities, could 
exceed safe levels maintained by the drainage and ventilation system.

DATES: This AD becomes effective February 25, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 25, 
2016.

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 January 26, 2015 (80 FR 3924). The NPRM was 
prompted by reports of fluid entry and accumulation in the aft 
equipment bay. The NPRM proposed to require modifying the aft equipment 
bay. We are issuing this AD to prevent excessive quantities of 
flammable fluid accumulation in the aft equipment bay. Flammable fluid 
entry and accumulation in the aft equipment bay, in excessive 
quantities, could exceed safe levels maintained by the drainage and 
ventilation system.
    Transport Canada Civil Aviation, which is the aviation authority 
for Canada, has issued Canadian Airworthiness Directive CF-2014-25, 
dated August 7, 2014 (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:

    There have been two reports of fluid entry and accumulation in 
the aft equipment bay. The leaked fluid in the first incident was 
fuel and the fluid in the second incident was test dye. Further 
investigation revealed that leaked fluid from the aft fuel tank 
drain entered the bay through the slot in the door latch mechanism.
    Flammable fluid entry and accumulation in the aft equipment bay, 
in excessive quantities, could exceed safe levels maintained by the 
drainage and ventilation system.
    Bombardier Inc. has issued several Service Bulletins (SB) to 
modify the Aft Equipment Bay by installing a cover to the door latch 
mechanism in order to reduce the risk of fuel entry into it. This 
[Canadian] AD mandates the incorporation of the applicable 
Bombardier Inc. SBs to rectify this problem.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-0081-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 3924, January 26, 
2015) 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 (80 FR 3924, January 26, 2015) for correcting the unsafe 
condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 3924, January 26, 2015).

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information:
    <bullet> Bombardier Service Bulletin 700-1A11-52-019, dated March 
29, 2012.
    <bullet> Bombardier Service Bulletin 700-52-042, dated March 29, 
2012.
    <bullet> Bombardier Service Bulletin 700-52-5007, dated March 29, 
2012.
    <bullet> Bombardier Service Bulletin 700-52-6007, dated March 29, 
2012.
    The service information describes procedures for the modification 
of the aft equipment compartment door. 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

    We estimate that this AD affects 60 airplanes of U.S. registry.
    We also estimate that it will take about 8 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 $720 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $84,000, or $1,400 per product.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.

    You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2015-0081; or in person at the 
Docket Management Facility between 9 a.m. and 5 p.m., Monday through
