ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation Model S-76D helicopters. This AD requires revising the rotorcraft flight manual (RFM) to prohibit Barometric Altitude Hold (ALT) mode beyond a certain rate of climb or descent. This AD is prompted by a report of the autopilot being unable to maintain level flight during certain flight conditions. The actions specified by this AD are intended to prevent a significant pilot workload increase, pilot disorientation, and subsequent loss of control of the helicopter. DATES: This AD becomes effective December 12, 2016. The Director of the Federal Register approved the incorporation by reference of a certain document listed in this AD as of December 12, 2016. We must receive comments on this AD by January 24, 2017. ADDRESSES: You may send comments by any of the following methods:Federal eRulemaking Docket: Go to http://www.regulations.gov.

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. [[Page 85125]] Discussion We are adopting a new AD for Sikorsky Aircraft Corporation Model S- 76D helicopters. This AD requires revising the ``Automatic Flight Control System'' section of the RFM Limitations by inserting a limitation prohibiting the use of the ALT mode during a rate of climb or descent greater than 1,000 feet/minute (fpm). This AD is prompted by a report of the autopilot being unable to maintain level flight in certain flight conditions. To explore the report further, the FAA conducted additional flight tests, which revealed that when the helicopter is at density altitudes greater than 13,000 feet and the autopilot is commanding either a climb or descent at rates greater than 1,000 fpm, and the ALT HOLD mode is then engaged, the autopilot is unable to maintain level flight when large collective inputs are applied. These conditions saturate the stability augmentation system (SAS) actuators, subsequently providing insufficient control response during the collective input. As a result, the helicopter may experience a dynamic response with roll excursions greater than 50 degrees of bank angle and yaw excursions greater than 70 degrees of heading. This condition could result in a significant increase in pilot workload, pilot disorientation, and loss of control of the helicopter. FAA's Determination We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other helicopters of this same type design. Related Service Information Under 1 CFR Part 51 Sikorsky issued S-76D RFM SA S76D-RFM-000, Temporary Revision No. 7, approved May 19, 2016, which revises the Limitations section by prohibiting ALT mode during a rate of climb or descent greater than 1,000 fpm. 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 (TIS), revising the Limitations section of the RFM by inserting a limitation stating that ALT mode shall not be engaged with a rate of climb or descent greater than 1,000 fpm. Interim Action We consider this AD to be an interim action. The design approval holder is planning to develop 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 will affect 12 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. At an average labor rate of $85 per work- hour, revising the RFM will require 0.5 work-hour, for cost of about $43 per helicopter and $516 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 unsafe condition can adversely affect control of the helicopter, and the required corrective actions must be accomplished within 10 hours TIS. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are impracticable and contrary to the public interest and that good cause exists for making this amendment 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 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.
