Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2016-08-05 for 
certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 
701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) 
airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and 
Model CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2016-08-05 
required replacement of affected angle of attack (AOA) transducers. 
This new AD requires the same actions as AD 2016-08-05. This new AD was 
prompted by a report of a typographical error in the regulatory text of 
AD 2016-08-05. We are issuing this AD to detect and replace incorrectly 
calibrated AOA transducers; incorrect calibration of the transducers 
could result in late activation of the stick pusher.

DATES: This AD is effective July 7, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 18, 2016

SUPPLEMENTARY INFORMATION: 

Discussion

    On March 31, 2016, we issued AD 2016-08-05, Amendment 39-18481 (81 
FR 21709, April 13, 2016) (``AD 2016-08-05''), for certain Bombardier, 
Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, 
Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-
2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 
(Regional Jet Series 1000) airplanes. AD 2016-08-05 was prompted by the 
discovery of a number of incorrectly calibrated AOA transducers 
installed in the stall protection system. AD 2016-08-05 required 
replacement of affected AOA transducers. We issued AD 2016-08-05 to 
detect and replace incorrectly calibrated AOA transducers; incorrect 
calibration of the transducers could result in late activation of the 
stick pusher.
    Since we issued AD 2016-08-05, we received a report of a 
typographical error in the regulatory text of AD 2016-08-05. Paragraph 
(h) of AD 2016-08-05 inadvertently stated, ``having a part number or 
serial number.'' This should have stated ``having a part number and 
serial number.'' We have revised paragraph (h) of this AD accordingly.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2015-18, dated July 16, 
2015 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 
701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) 
airplanes, Model CL-600-2D24

[[Page 40491]]

(Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional 
Jet Series 1000) airplanes. The MCAI states:

    It was discovered that a number of AOA transducers installed on 
Bombardier CL-600-2C10, CL-600-2D15, CL-600-2D24, and CL-600-2E25 
aeroplanes were incorrectly calibrated due to a quality control 
problem at both the production and repair facilities. Incorrect 
calibration of the AOA transducer could result in a late activation 
of the stick pusher.
    This [Canadian] AD mandates the replacement of the incorrectly 
calibrated AOA transducer.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
7265.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 670BA-27-069, dated March 
30, 2015. This service information describes procedures for replacement 
of incorrectly calibrated AOA transducers with correctly calibrated AOA 
transducers. 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.

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

FAA's Justification and Determination of the Effective Date

    We are superseding AD 2016-08-05 to correct a typographical error 
in the regulatory text. No other changes have been made to AD 2016-08-
05. Therefore, we determined that notice and opportunity for public 
comment are unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2016-7265; Directorate 
Identifier 2016-NM-084-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 400 airplanes of U.S. registry.
    We also estimate that it would take about 4 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts would cost about $10,000 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $4,136,000, or $10,340 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 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.
