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 proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive. Discussion We propose to adopt a new AD for Scotts-Bell Model 47, 47B, 47B3, 47D, 47D1, 47E, 47G, 47G-2, 47G-2A, 47G-2A-1, 47G-3, 47G-3B, 47G-3B-1, 47G-3B-2, 47G-3B-2A, 47G-4, 47G-4A, 47G-5, 47G-5A, 47H-1, 47J, 47J-2, 47J-2A, and 47K helicopters with a Marvel Schebler Model MA-3, MA-3A, MA3-PA, MA-3SPA, MA4-SPA, MA4-5, MA4-5AA, MA-5, MA-5AA, MA-6AA, or HA-6 carburetor installed. This proposed AD would require an initial inspection and repetitive daily check of the throttle linkage- carburetor attachment for broken or missing safety wire and for fracturing of the anti-sabotage lacquer. This proposed AD would also require adjusting and securing the throttle linkage within 100 hours time-in-service. This proposed AD is prompted by several reports of the throttle linkage separating from the engine carburetor shaft, which resulted in loss of throttle control. An investigation determined that missing or improperly installed safety wire may fail to prevent an excessively worn splined carburetor shaft from separating from the throttle linkage. The investigation further determined that the unusual routing of the safety wire in this design along with a lack of clarity in the maintenance instructions may have contributed to nine other incidents. To address this unsafe condition, Scotts-Bell has developed an inspection to determine whether the safety wire is correctly applied and has revised the maintenance instructions with updated procedures for safety wire installation. While our data indicates Model 47, 47B, 47B3, 47D, 47E, and 47K helicopters are not likely to have the affected carburetors installed, we have included those models in this proposed AD to ensure we fully address the unsafe condition. FAA's Determination We are proposing this AD because we evaluated all known relevant [[Page 23241]] information and determined that an unsafe condition exists and is likely to exist or develop on other products of these same type designs. Related Service Information Under 1 CFR Part 51 We reviewed Scott's-Bell 47, Inc. Alert Service Bulletin 47-15-27 R1, dated November 1, 2016 (ASB), for Model 47, 47B, 47B3, 47D, 47D1, 47E, 47G, 47G-2, 47G-2A, 47G-2A-1, 47G-3, 47G-3B, 47G-3B-1, 47G-3B-2, 47G-3B-2A, 47G-4, 47G-4A, 47G-5, 47G-5A, 47H-1, 47J, 47J-2, 47J-2A, and 47K helicopters. The ASB specifies, prior to the next flight, inspecting the engine throttle linkage and carburetor shaft to determine if the safety wire is correctly applied. The ASB also specifies adjusting and securing the throttle linkage at the next 100- hour or annual inspection, but no later than 90 days after release of the ASB, and then any time the throttle linkage connection is disassembled. 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. Other Related Service Information We also reviewed Scott's-Bell 47, Inc. Model 47D-1, 47G, & 47G-2 Maintenance and Overhaul Instructions Temporary Revision (M&O TR) 47- 16-2, Models 47G-2A & 47G-2A-1 M&O TR 47-16-3, Model 47G-3 M&O TR 47- 16-3, Models 47G-3B & 47G-3B-1 M&O TR 47-16-3, Model 47G-3B-2 M&O TR 47-16-3, Model 47G-3B-2A M&O TR 47-16-3, Models 47G-4 & 47G-4A M&O TR 47-16-3, Model 47G-5 M&O TR 47-16-3, Model 47G-5A M&O TR 47-16-3, Model 47H-1 M&O TR 47-16-2, Model 47J M&O TR 47-16-2, and Models 47J-2 & 47J- 2A M&O TR 47-16-3, each dated November 1, 2016. Each M&O TR describes procedures for inspecting and safety wiring the throttle control linkage. Scott's Bell did not issue temporary revisions to the M&O procedures for Model 47, 47B, 47B3, 47D, 47E, and 47K helicopters, as there are limited manufacturing and maintenance records available for these models, and as it is unlikely these models have an affected model carburetor installed. Proposed AD Requirements This proposed AD would require the following: Before further flight, inspecting the throttle linkage connection at the engine carburetor for condition, security, and to determine if the safety wire is in place and captures the throttle linkage and the carburetor stop arm. Before the first flight of each day, visually checking the throttle-linkage to carburetor attachment for installed safety wire and for intact anti-sabotage lacquer. An owner/operator (pilot) may perform the visual check required by paragraph (e)(2)(i) of the proposed AD and must enter compliance with that paragraph into the helicopter maintenance records in accordance with 14 CFR 43.9(a)(1) through (4) and 91.417(a)(2)(v). A pilot may perform this check because it involves only a visual check of the throttle-linkage to carburetor attachment and can be performed equally well by a pilot or a mechanic. This check is an exception to our standard maintenance regulations. Within 100 hours time-in-service or at the next annual or 100-hour inspection, whichever occurs first, and thereafter at each annual or 100-hour inspection, whichever occurs first, adjusting, safety wiring, and applying anti-sabotage lacquer to the throttle linkage. For Model 47, 47B, 47B3, 47D, 47E, and 47K helicopters, adjusting and safety wiring the throttle linkage would be required to be done by using a method approved by the Manager, Chicago ACO Branch. For all other helicopters, these actions would be accomplished as specified in the applicable M&O TR. Costs of Compliance We estimate that this proposed AD would affect 698 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this proposed AD. Conducting a pre-flight check of the throttle linkage connection by the pilot would require about 5 minutes, therefore the cost per helicopter would be minimal. At an average labor rate of $85, inspecting the engine throttle linkage would require about 0.5 work-hour, for a cost of $43 per helicopter and $30,014 for the U.S. fleet. Adjusting and securing the throttle linkage would require about 3 work-hours and required parts would be $12 for a cost of $267 per helicopter and $186,366 for the U.S. fleet per occurrence. 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, 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 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 proposed AD and placed it in the AD docket. 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.
