[[Page 23159]] Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016-0234, dated November 24, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) airplanes. The MCAI states: Circuit breakers of an unsuitable strength have been found installed on SAAB SF340A aeroplanes, failing in protecting the system from an overcurrent. This condition, if not corrected, could lead to the overheating of wires, possibly resulting in smoke or fire on the aeroplane. To address this potential unsafe condition, Saab issued [service bulletin] SB 340-33-058 (later revised) to provide instructions for replacement of circuit breakers. For the reason described above, this [EASA] AD requires replacement of circuit breakers of unsuitable strength in the passenger reading light system. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017- 0479. Related Service Information Under 1 CFR Part 51 We reviewed Saab Service Bulletin 340-33-058, Revision 01, dated October 21, 2016. The service information describes procedures for replacing any circuit breaker having part number (P/N) MS3320-10 installed at position 2LJ (L25) and position 4LJ (L26) with a circuit breaker having P/N MS3320-7-5. 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. FAA's Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD affects 19 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Replacement........................... 2 work-hours x $85 per $220 $390 $7,410 hour = $170. ---------------------------------------------------------------------------------------------------------------- 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 above, 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; 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 adding the following new airworthiness directive (AD): Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab Aerosystems): Docket No. FAA-2017-0479; Directorate Identifier 2016- NM-202-AD. (a) Comments Due Date We must receive comments by July 6, 2017. (b) Affected ADs None.

(d) Subject Air Transport Association (ATA) of America Code 33, Lights. (e) Reason This AD was prompted by the discovery of circuit breakers of unsuitable strength that fail to protect the system from overcurrent. We are issuing this AD to prevent such conditions, which could lead to overheating of the wires and possibly result in smoke or fire in the airplane. [[Page 23160]] (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Replacement Within 6 months after the effective date of this AD: Replace any circuit breaker having part number (P/N) MS3320-10 installed at position 2LJ (L25) and position 4LJ (L26) with a circuit breaker having P/N MS3320-7-5, in accordance with the Accomplishment Instructions of Saab Service Bulletin 340-33-058, Revision 01, dated October 21, 2016. (h) Parts Installation Prohibition As of the effective date of this AD, no person may install a circuit breaker P/N MS3320-10 on any passenger reading light system at position at 2LJ (L25) and position 4LJ (L26), on any airplane.
