[Federal Register Volume 82, Number 40 (Thursday, March 2, 2017)] [Proposed Rules] [Pages 12310-12312] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-03952] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0157; Directorate Identifier 2016-CE-039-AD] RIN 2120-AA64 Airworthiness Directives; Piper Aircraft, Inc. Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede Airworthiness Directive (AD) 69-13-03, which applies to all Piper Aircraft, Inc. Models PA-23, PA-23-160, PA- 23-235, PA-23-250, PA-E23-250, and PA-30 airplanes. AD 69-13-03 currently requires inspection of the heater exhaust extension, replacement of the extension as necessary, and overhaul of the combustion heater assembly. Since we issued AD 69-13-03, we proposed an AD that applies to the Meggitt (Troy), Inc. combustion heaters, and the proposed combustion heater AD would incorporate corrective actions for the heater that contradict the overhaul requirement of AD 69-13-03. This proposed AD would retain the inspection of the heater exhaust extension, with replacement of the extension as necessary, and remove the overhaul requirement of the combustion heater assembly. We are proposing this AD to correct the unsafe condition on these products. DATES: We must receive comments on this proposed AD by April 17, 2017. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments. Fax: 202-493-2251. Mail: U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590. Hand Delivery: Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. Examining the AD Docket You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017- 0157; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this proposed AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (phone: 800-647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. FOR FURTHER INFORMATION CONTACT: Scott Hopper, Aerospace Engineer, FAA, Atlanta Aircraft Certification Office, 1701 Columbia Avenue, College Park, Georgia 30337; phone: (404) 474-5535; fax: (404) 474-5606; email: [email protected]. SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2017-9157; Directorate Identifier 2016-CE-039-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We issued AD 69-13-03, Amendment 39-1749 (38 FR 33765, December 7, 1973) (``AD 69-13-03''), for certain Piper Aircraft, Inc. Models PA-23, PA-23-160, PA-23-235, PA-23-250, PA-E23-250, and PA-30 airplanes. AD 69-13-03 requires inspection of the heater exhaust extension to determine if it is mild steel or stainless steel, repetitive inspections of the mild steel extensions for deterioration, replacing the extension as necessary, and overhaul of the combustion heater assembly. AD 69-13-03 resulted from the potential of carbon monoxide entering the airplane [[Page 12311]] cabin. We issued AD 69-13-03 to prevent carbon monoxide from entering the airplane cabin. Actions Since AD 69-13-03 Was Issued Since we issued AD 69-13-03, we proposed an AD that applies to the Meggitt (Troy), Inc. combustion heaters installed on the airplanes AD 69-13-03 applies to. The proposed combustion heater AD would incorporate corrective actions for the heater that contradict the overhaul requirement of AD 69-13-03. The NPRM for the Meggitt (Troy), Inc. combustion heaters was published in the Federal Register on November 3, 2016 (81 FR 76532). You may view the docket for the Meggitt NPRM by going to http://www.regulations.gov and searching for Docket No. FAA-2014-0603. FAA's Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would retain certain requirements of AD 69-13-03. This proposed AD would remove the requirement for overhaul of the heater assembly. Costs of Compliance We estimate that this proposed AD affects 1,950 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD. The new requirements of this proposed AD add no additional economic burden: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Determine installation of a mild steel 1 work-hour x $85 per N/A $85 $165,750 or stainless steel heater exhaust hour = $85. extension. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary corrective actions that would be required based on the results of the proposed inspection. We have no way of determining the number of airplanes that might need these corrective actions: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Inspection of mild steel heater exhaust 1 work-hour x $85 per hour Not applicable............ $85 extension. = $85. Replacement of heater exhaust extension. 1 work-hour x $85 per hour $1,000 *.................. 1,085 = $85. Remove or disable the heater............ 1 work-hour x $85 per hour Not applicable............ 85 = $85. ---------------------------------------------------------------------------------------------------------------- * There are currently no replacement parts available for the heater exhaust extension. The $1,000 parts cost is the FAA's best estimate if parts were to become available. 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 have 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 that the 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 removing Airworthiness Directive (AD) 69-13-03, Amendment 39-1749 (38 FR 33765, December 7, 1973), and adding the following new AD: Piper Aircraft, Inc.: Docket No. FAA-2017-0157; Directorate Identifier 2016-CE-039-AD. [[Page 12312]] (a) Comments Due Date The FAA must receive comments on this AD action by April 17, 2017. (b) Affected ADs This AD replaces Airworthiness Directive (AD) 69-13-03, Amendment 39-1749 (38 FR 33765, December 7, 1973) (``AD 69-13-03''). (c) Applicability This AD applies to Piper Aircraft, Inc. Models PA-23, PA-23-160, PA-23-235, PA-23-250, PA-E23-250, and PA-30 airplanes, all serial numbers, certificated in any category. (d) Subject Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 21, Air Conditioning.
