[Federal Register Volume 81, Number 90 (Tuesday, May 10, 2016)] [Proposed Rules] [Pages 28766-28768] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-10860] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-6551; Directorate Identifier 2013-SW-070-AD] RIN 2120-AA64 Airworthiness Directives; Bell Helicopter Textron Helicopters AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Bell Helicopter Textron (Bell) Model 430 helicopters. This proposed AD would require establishing a life limit for a certain main rotor hub attachment bolt (bolt) and removing from service each bolt that has met or exceeded its life limit. This proposed AD is prompted by a documentation error that omitted the life limit of a certain part- numbered bolt from the Airworthiness Limitations section of the maintenance manual. The proposed actions are intended to establish a life limit for a certain part-numbered bolt to prevent failure of a bolt, failure of a main rotor hub, and subsequent loss of control of a helicopter. DATES: We must receive comments on this proposed AD by July 11, 2016. ADDRESSES: You may send comments by any of the following methods:Federal eRulemaking Docket: Go to http://www.regulations.gov.

Discussion Transport Canada, which is the aviation authority for Canada, has issued AD No. CF-2013-26, dated September 24, 2013, to correct an unsafe condition for certain serial-numbered Bell Model 430 helicopters. Transport Canada advises that bolt part number (P/N) MS21250-08083, which replaced bolt P/N 20-065-08083 in 2009, has a retirement life of 5,000 hours. However, the retirement life for the replacement bolt was inadvertently omitted from the limitations section of the Bell 430 maintenance manual. Transport Canada advises that this situation, if not corrected, could result in failure of a bolt and loss of control of the helicopter. Transport Canada AD No. CF-2013-26 requires reviewing the helicopter records to determine if bolt P/N MS21250-08083 is installed, creating a historical service record, and establishing an airworthiness life of 5,000 hours air time. FAA's Determination This helicopter has been approved by the aviation authority of Canada and is approved for operation in the United States. Pursuant to our bilateral agreement with Canada, Transport Canada, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information We reviewed Bell Helicopter Alert Service Bulletin 430-12-47, dated November 14, 2012 (ASB). The ASB states that original bolt P/N 20-065- 08083 has a retirement life of 5,000 hours but has been replaced by standard bolt P/N MS21250-08083, which does not have a life limit listed in the maintenance manual. The purpose of the ASB is to establish a life limit of 5,000 hours for the replacement bolt. Bell specifies reviewing the aircraft records back to January 2009 to determine which part-numbered bolts are installed. If a replacement bolt P/N MS21250-08083 is installed, the ASB specifies using data from aircraft records to create a historical service record for the replacement bolts and reflecting the 5,000 hours life limit. The ASB also specifies updating the Bell 430 maintenance manual. Proposed AD Requirements This proposed AD would require within 10 hours time-in-service (TIS), revising the Airworthiness Limitations section of the applicable maintenance manual or Instructions for Continued Airworthiness (ICA) by establishing a life limit of 5,000 hours TIS for each bolt P/N MS21250- 08083. This proposed AD would also require determining the number of hours TIS for each bolt and using the helicopter's hours if the hours TIS of a bolt is unknown. This proposed AD would also require removing from service each bolt that has reached or exceeded its life limit. Differences Between This Proposed AD and the Transport Canada AD The proposed AD would require compliance within 10 hours TIS, while the Transport Canada AD requires compliance within 60 days. Costs of Compliance We estimate that this proposed AD would affect 43 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 cost of $85 per work-hour, we estimate reviewing and revising the records would require 1 work-hour for a cost of about $85 per helicopter and $3,655 for the U.S. fleet. We estimate replacing a bolt that has exceeded its life limit would require 0.5 work-hour plus $290 for a replacement bolt, for a total cost of $333 per bolt. 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 [[Page 28768]] 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. 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): Bell Helicopter Textron: Docket No. FAA-2016-6551; Directorate Identifier 2013-SW-070-AD. (a) Applicability This AD applies to Model 430 helicopters, serial number 49001 through 49129, with a main rotor head attachment bolt (bolt) part number MS21250-08083 installed, certificated in any category. (b) Unsafe Condition This AD defines the unsafe condition as a bolt remaining in service beyond its fatigue life. This condition could result in failure of a bolt, failure of the main rotor hub and subsequent loss of control of a helicopter. (c) Comments Due Date We must receive comments by July 11, 2016. (d) Compliance You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
