14 CFR Part 39

[Docket No. FAA-2013-0332; Directorate Identifier 2013-NM-009-AD; 
Amendment 39-17637; AD 2013-22-05]
RIN 2120-AA64


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 CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 
Variants) airplanes. This 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 AD requires, for certain 
airplanes, inspecting for drain bottles having certain part numbers, 
and replacing affected drain bottles. This AD requires, for certain 
other airplanes, replacing drain bottles. We are issuing 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: This AD becomes effective December 5, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 5, 
2013.

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 the specified products. The 
NPRM was published in the Federal Register on April 17, 2013 (78 FR 
22806). The NPRM proposed to correct an unsafe condition for the 
specified products.
    Transport Canada Civil Aviation, which is the aviation authority 
for Canada, has issued Canadian

[[Page 65191]]

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 examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0332-0002.

Comments

We gave the public the opportunity to participate in developing this 
AD. We received no comments on the NPRM (78 FR 22806, April 17, 2013) 
or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed--except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 22806, April 17, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 22806, April 17, 2013).

Costs of Compliance

    We estimate that this AD affects 77 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
               Action                        Labor cost           Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Replacement.........................  5 work-hours x $85 per           $2,939           $3,364         $259,028
                                       hour = $425.
----------------------------------------------------------------------------------------------------------------

    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.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
