RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes.
This proposed AD was prompted by reports of fluid entry and
accumulation in the aft equipment bay. This proposed AD would require
modifying the aft equipment bay. We are proposing 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: We must receive comments on this proposed AD by March 12, 2015.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion
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 by searching for and locating Docket No. FAA-2015-
0081.
Related Service Information
Bombardier has issued the following service information:
Bombardier Service Bulletin 700-1A11-52-019, dated March
29, 2012.
Bombardier Service Bulletin 700-52-042, dated March 29,
2012.
Bombardier Service Bulletin 700-52-5007, dated March 29,
2012.
Bombardier Service Bulletin 700-52-6007, dated March 29,
2012.
The service information describes procedures for the modification
of the aft equipment compartment door. The actions described in this
service information are intended to correct the unsafe condition
identified in the MCAI.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
[[Page 3925]]
Costs of Compliance
We estimate that this proposed AD affects 60 airplanes of U.S.
registry.
We also estimate that it would take about 8 work-hours per product
to comply with the basic requirements of this proposed AD. The average
labor rate is $85 per work-hour. Required parts would cost about 720
per product. Based on these figures, we estimate the cost of this
proposed AD on U.S. operators to be $84,000, or $1,400 per product.
According to the manufacturer, some of the costs of this proposed
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
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.
