The MCAI describes the unsafe condition as the brakes remaining activated after release of the brake pedal. We are issuing this proposed AD to require actions to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by January 5, 2018.

Discussion The Federal Office of Civil Aviation (FOCA), which is the aviation authority for Switzerland, has issued FOCA AD HB-2017-002, dated October 20, 2017 (referred to after this as ``the MCAI''), to correct an unsafe condition for Pilatus Aircraft Limited Model PC-7 airplanes. The MCAI states: This [FOCA] Airworthiness Directive (AD) is prompted due to a report where the brakes have remained activated after release of the brake pedals before taxing. Such a condition, if left uncorrected, could lead to an asymmetric braking and subsequent loss of directional control. In order to correct and control the situation, this [FOCA] AD requires the modification of the brake-pedal interconnecting tie-rod by removing the bonding straps and attachment hardware currently installed on the left and right brake-pedal interconnecting tie- rods. You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-1079. Related Service Information Under 1 CFR Part 51 Pilatus Aircraft Limited has issued Pilatus Service Bulletin No. 32-028, dated September 20, 2017. The service information describes procedures for removing the left and right brake pedal interconnecting tie rods. 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 of this NPRM. FAA's Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. [[Page 55333]] Costs of Compliance We estimate that this proposed AD will affect 18 products of U.S. registry. We also estimate that it would take about 2.5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $3,825, or $212.50 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes and domestic business jet transport airplanes to the Director of the Policy and Innovation Division. 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 AD: Pilatus Aircraft Limited: Docket No. FAA-2017-1079; Product Identifier 2017-CE-039-AD. (a) Comments Due Date We must receive comments by January 5, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Pilatus Aircraft Limited Model PC-7 airplanes, manufacturer serial numbers 101 through 618, certificated in any category. (d) Subject Air Transport Association of America (ATA) Code 32: Landing Gear. (e) Reason This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the brakes remaining activated after release of the brake pedal. We are issuing this AD to prevent the brakes from remaining activated after the brake pedal has been released, which could lead to asymmetric braking and subsequent loss of control. (f) Actions and Compliance Unless already done, within the next 90 days after the effective date of this AD, modify the brake pedal interconnecting tie rods by removing the bonding straps and attachment hardware following sections A, B, and C of the Accomplishment Instructions in Pilatus Service Bulletin 32-028, dated September 20, 2017. (g) Other FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Small Airplane Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Doug Rudolph, Aerospace Engineer, FAA, Small Airplane Standards Branch, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4059; fax: (816) 329- 4090; email: doug.rudolph@faa.gov. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the Manager, Small Airplane Standards Branch, FAA; or the Federal Office of Civil Aviation (FOCA), which is the aviation authority for Switzerland. (h) Related Information Refer to MCAI FOCA AD HB-2017-002, dated October 20, 2017; and Pilatus Service Bulletin No. 32-028, dated September 20, 2017, for related information.
