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 DHC-8-102, -103, and -106 airplanes, Model DHC- 8-200 series airplanes, and Model DHC-8-300 series airplanes. This AD was prompted by several occurrences of loss of airspeed data on both pilot and co-pilot air speed indicators due to the accumulation of ice on the pitot probes caused by inoperative pitot probe heaters. This AD requires replacing the existing circuit breakers in the pitot heater system. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective January 12, 2017. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of January 12, 2017. ADDRESSES: For service information identified in this final rule, contact Bombardier, Inc., Q-Series Technical Help Desk, 123 Garratt Boulevard, Toronto, Ontario M3K 1Y5, Canada; telephone: 416-375-4000; fax: 416-375-4539; email: thd.qseries@aero.bombardier.com; Internet: http://www.bombardier.com.

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 DHC-8-102, -103, and -106 airplanes, Model DHC-8-200 series airplanes, and Model DHC-8-300 series airplanes. The NPRM published in the Federal Register on June 28, 2016 (81 FR 41897) (``the NPRM''). Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2016-04, dated February 1, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes, Model DHC-8-200 series airplanes, and Model DHC-8-300 series airplanes. The MCAI states: [[Page 88620]] There have been several occurrences of loss of airspeed data on both pilot and co-pilot Airspeed Indicators (ASI) due to the accumulation of ice on the pitot probes. Subsequent investigation revealed that the build up of ice on the pitot probes was due to inoperative pitot probe heaters. When flying in heavy precipitations, the increased heat required by the pitot probe to clear ice build up may result in a current demand in excess of the trip point of the associated circuit breakers (CB). Under this condition, the CB may trip and cut power supply to the heater. If not corrected, the loss of airspeed data may result in the crew not being able to control the aeroplane's airspeed. This [Canadian] AD is issued to mandate the replacement of the existing CBs with CBs that have higher trip points. 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-2016- 7267. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment. The Airline Pilots Association, International, stated that it supported the NPRM. Request To Revise the Cost of Compliance Bombardier, Inc. requested that we correct the cost of the pitot heaters. Bombardier, Inc. stated that we provided the cost of left-hand pitot heater ($1,194), but not the right-hand pitot heater. Bombardier Inc. stated that the cost of the right-hand pitot heater is $1,155. We agree with the commenter's request for the reasons provided. We have revised this AD accordingly. Request To Revise the Requirements in the NPRM Bombardier, Inc. requested that we omit the phrase ``in production'' in the first sentence of paragraph (h) of the proposed AD. Bombardier, Inc. stated that ModSum IS8Q3000004 was incorporated in service. We agree with the commenter for the reason stated above. We have revised this AD accordingly. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and 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. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Service Bulletin 8-30-39, dated November 11, 2015, and Bombardier Service Bulletin 8-30-40, dated November 11, 2015. The service information describes procedures for replacing the existing circuit breakers in both the left and right sides of the pitot heater system with circuit breakers that have higher trip points. These documents are distinct since they apply to different sides of the airplane. 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 83 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 (Left-hand pitot)...... 20 work-hours x $85 per $1,194 $2,894 $240,202 hour = $1,700. Replacement (Right-hand pitot)..... 20 work-hours x $85 per 1,155 2,855 236,965 hour = $1,700. ---------------------------------------------------------------------------------------------------------------- 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. [[Page 88621]] Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2016-24-06 Bombardier, Inc.: Amendment 39-18723; Docket No. FAA- 2016-7267; Directorate Identifier 2016-NM-015-AD.
