Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2015-4814; Directorate Identifier 2015-NM-105-AD; 
Amendment 39-18502; AD 2016-09-04]
RIN 2120-AA64


Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) 
airplanes. This AD was prompted by the discovery of a number of 
incorrectly calibrated angle of attack (AOA) transducers installed in 
the stall protection system. This AD requires replacement of 
incorrectly calibrated AOA transducers. 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 June 6, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 6, 
2016.

ADDRESSES: For service information identified in this final rule, 
contact Bombardier, Inc., 400 C[ocirc]te-Vertu Road West, Dorval,

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 CL-600-2B19 (Regional Jet Series 100&440) airplanes. The NPRM 
published in the Federal Register on November 17, 2015 (80 FR 71749) 
(``the NPRM''). The NPRM was prompted by the discovery of a number of 
incorrectly calibrated AOA transducers installed in the stall 
protection system. The NPRM proposed to require replacement of 
incorrectly calibrated AOA transducers. 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.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2015-17, effective 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-600-2B19 (Regional Jet 
Series 100 & 440) airplanes. The MCAI states:

    It was discovered that a number of [angle of attack] AOA 
transducers installed on Bombardier CL-600-2B19 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 in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
4814.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM 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:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 601R-27-164, dated March 
30, 2015. The service information describes procedures for replacement 
of incorrectly 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.

Costs of Compliance

    We estimate that this AD affects 575 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 $5,945,500, 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

[[Page 26103]]

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

    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 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.
