Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2016-27, dated September 14, 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-8-401 and DHC-8-402 airplanes. The MCAI states: An operator reported that the flying pilot was unable to move the rudder pedal due to an obstruction caused by the non-flying pilot's foot. The shoe belonging to the non-flying pilot was placed between the rudder pedal and the newly installed wiring shroud and prevented rudder pedal movement. The wiring shroud was installed to support the wire harnesses installed below the cockpit instrument panel. If not corrected, this condition could prevent rudder movement during critical phases of flight or ground operation, and result in loss of control of the aeroplane. This [Canadian] AD was issued to re-work the wiring shrouds to eliminate potential for obstruction. Required actions include an inspection for the presence of wiring shrouds and modification of any existing wiring shrouds. 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-2017- 0125. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Service Bulletin 84-25-169, Revision A, dated April 25, 2016. This service information describes procedures for an inspection to verify if wiring shrouds are installed, and modification of any existing wiring shrouds. 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 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 [[Page 12302]] 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 We estimate that this proposed AD affects 82 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection................... 1 work-hour x $85 per hour = $85. $0 $85 $6,970 ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary modifications that would be required based on the results of the proposed inspection. We have no way of determining the number of airplanes that might need these modifications: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Modification of wiring shrouds............. 7 work-hours x $85 per hour = $595. $71 $666 ---------------------------------------------------------------------------------------------------------------- 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 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. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): Bombardier, Inc.: Docket No. FAA-2017-0125; Directorate Identifier 2016-NM-193-AD. (a) Comments Due Date We must receive comments by April 17, 2017. (b) Affected ADs None.

(d) Subject Air Transport Association (ATA) of America Code 25, Equipment/ furnishings. (e) Reason This AD was prompted by a report that a pilot was unable to move the rudder pedal due to an obstruction caused by the non-flying pilot's foot. We are issuing this AD to prevent an obstruction that could prevent rudder pedal movement during critical phases of flight or ground operations, potentially resulting in loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Inspection and Modification of Wiring Shrouds Within 6 months after the effective date of this AD, do a one- time inspection to determine if wiring shrouds are installed, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 84-25-169, Revision A, dated April 25, 2016. (1) If the airplane does not have wiring shrouds installed, no further action is required by this AD. (2) If the airplane has wiring shrouds installed, before further flight, modify the wiring shrouds in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 84-25- 169, Revision A, dated April 25, 2016. Note 1 to paragraph (g) of this AD: Wiring shrouds were installed in accordance with Bombardier Modification Summary Package (ModSum) IS4Q2500035-1, Revision A, dated July 26, 2011; Revision B, dated October 10, 2013; Revision C, dated March 26, 2014; or Revision D, dated February 26, 2016; or ModSum IS4Q2500035-2, Revision A, dated July 26, 2011; Revision B, dated October 10, 2013; Revision C, dated March [[Page 12303]] 26, 2014; or Revision D, dated February 26, 2016.
