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 CL-600-2B16 (CL-601-3A, CL-601-3R, and
CL-604 Variants) airplanes. This proposed AD was prompted by reports of
airspeed mismatch between the pilot and co-pilot's airspeed indicators,
which occurred during or after heavy rain. This proposed AD would
require, for certain airplanes, inspecting for drain bottles having
certain part numbers, and replacing affected drain bottles. This
proposed AD would require, for certain other airplanes, replacing drain
bottles. We are proposing this AD to prevent pitot static tubing from
becoming blocked by water, which if not corrected, could lead to
erroneous airspeed and altitude indications, and consequent loss of
control of the airplane.
DATES: We must receive comments on this proposed AD by June 3, 2013.
ADDRESSES: You may send comments by any of the following methods:

Discussion
Transport Canada Civil Aviation, which is the aviation authority
for Canada, has issued Canadian Airworthiness Directive CF-2012-30,
dated December 7, 2012 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for the specified products. The MCAI states:
A number of reports were received from the operators indicating
airspeed mismatch between the pilot and co-pilot's airspeed
indicators. The erroneous indication occurred during or after heavy
rain. Further investigation revealed that during heavy
precipitation, the pitot static tubing may become partially or
completely blocked by the water which didn't enter the drain
bottle(s). This condition, if not corrected, may result in erroneous
airspeed and altitude indications [and consequent loss of control of
the airplane].
This [Canadian] AD mandates [for certain airplanes] the replacement
of the drain bottles to improve drainage of the pitot-static tubing
[and, for certain other airplanes, an inspection for, and
replacement of, certain drain bottles].
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Bombardier, Inc. has issued the following service bulletins. The
actions described in this service information are intended to correct
the unsafe condition identified in the MCAI.
Bombardier Service Bulletin 601-0617, Revision 03, dated
December 20, 2012.
Bombardier Service Bulletin 604-34-065, Revision 02, dated
December 20, 2012.
Bombardier Service Bulletin 605-34-027, Revision 02, dated
December 20, 2012.
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.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 77 products of U.S. registry. We also estimate that
it would take about 5 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 up to $2,939 per
[[Page 22807]]
product. Where the service information lists required parts costs that
are covered under warranty, we have assumed that there will be no
charge for these parts. As we do not control warranty coverage for
affected parties, some parties may incur costs higher than estimated
here. Based on these figures, we estimate the cost of the proposed AD
on U.S. operators to be $259,028, or $3,364 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 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
