SUPPLEMENTARY INFORMATION: Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments prior to it becoming effective. However, we invite you to participate in this rulemaking by submitting written comments, data, or views. We also invite comments relating to the economic, environmental, energy, or federalism impacts that resulted from adopting this AD. The most helpful comments reference a specific portion of the AD, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit them only one time. We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this rulemaking during the comment period. We will consider all the comments we receive and may conduct additional rulemaking based on those comments. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2017-0146, dated August 10, 2017, to correct an unsafe condition for Airbus Helicopters Model MBB-BK 117 D-2 helicopters. EASA advises that two incidents of uncommanded helicopter climbs and descents have been reported following activation of the autopilot cruise height (CRHT) mode concurrently with the ground trajectory command in hover mode (GTCH). EASA advises this condition, if not detected and corrected, could lead to temporary loss of control of the helicopter or injury to the helicopter's occupants. To address this unsafe condition, EASA requires a minimum airspeed limitation of 40 knots for the autopilot CRHT mode. Since the rotorcraft cannot enter GTCH mode at speeds above 40 knots, under this limitation, CRHT mode will not be engaged concurrently with GTCH mode. EASA considers its AD interim action, pending an autopilot software upgrade to prevent further occurrences. FAA's Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. Related Service Information Under 1 CFR Part 51 We reviewed Airbus Helicopters BK117 D-2 Flight Manual Temporary Revision No. 1, dated March 28, 2017, for Model BK117 D-2 helicopters, and Airbus Helicopters BK117 D-2 (Helionix Step 2) Flight Manual Temporary Revision No. 1, dated March 28, 2017, for Model BK117 D-2 helicopters with Helionix Step 2. These temporary revisions establish a minimum airspeed limitation of 40 knots for the autopilot CRHT mode. 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. AD Requirements This AD requires, within 10 hours time-in-service, revising the Operating Limitations section of the rotorcraft flight manual by adding a minimum airspeed limitation for the autopilot of 40 knots when CRHT mode is engaged. Interim Action We consider this AD to be an interim action. The design approval holder is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking. Costs of Compliance We estimate that this AD affects 16 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect that making the required changes to the rotorcraft flight manual will require 0.5 work-hour and no parts are needed for a cost of $43 per helicopter and $688 for the U.S. fleet. FAA's Justification and Determination of the Effective Date Providing an opportunity for public comments prior to adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we find that the risk to the flying public justifies waiving notice and comment prior to the adoption of this rule because the required corrective actions must be accomplished within 10 hours time-in-service. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for prior public comment before issuing this AD are impracticable and contrary to the public interest and that good cause exists to make this AD effective in less than 30 days. 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 [[Page 56165]] 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, 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 to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.
