SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes and Model ATR72- 102, -202, -212, and -212A airplanes. The NPRM published in the Federal Register on December 1, 2016 (81 FR 86627). The NPRM was prompted by reports of failure of EPSUs in production and in service. The NPRM proposed to require an inspection to determine the part number and serial number of each EPSU, and replacement if necessary. We are issuing this AD to detect and correct defective internal electronic components, which could adversely affect the EPSU internal battery. This condition could result in a partial or total loss of emergency lighting, possibly affecting passenger evacuation during an emergency situation. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016-0070, dated April 11, 2016; corrected April 12, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''); to correct an unsafe condition for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes and Model ATR72-102, -202, -212, and -212A airplanes. The MCAI states: Some failure cases have been reported of emergency power supply units (EPSU), Part Number (P/N) 301-3100 Amdt [Amendment] A, both on the production line and in service. The results of the technical investigations revealed that these failures could have been caused by a defective internal electronic component, which could affect the EPSU internal battery charge. This condition, if not detected and corrected, could result in a partial or total (depending on number of affected EPSUs installed) loss of emergency lighting, possibly affecting passenger evacuation during an emergency situation. To address this potential unsafe condition, ATR issued Service Bulletin (SB) ATR42-33-0050 and SB ATR72-33-1043 to provide instructions to inspect EPSUs. For the reason described above, this [EASA] AD requires identification and replacement of the affected EPSUs with serviceable units. This [EASA] AD was republished to correct two typographical errors in paragraph (3) of the [EASA] AD and to specify the correct Revision (3) of the Cobham SB 301-3100-33-002. 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-2016- 9430. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA's response to that comment. [[Page 23495]] Request To Refer to Revised Service Information Empire Airlines requested that the NPRM be revised to refer to the current revision levels of the applicable ATR service information, which were issued by ATR after the NPRM was published in the Federal Register. Empire Airlines noted that the revised service information does not include any additional actions for airplanes on which the previous service information was accomplished and the serial numbers of the parts to be inspected have not changed. We agree with the commenter's request for the reasons provided by the commenter. In paragraph (g) of the proposed AD, we identified ATR Service Bulletin ATR42-33-0050, Revision 01, dated January 26, 2016; and ATR Service Bulletin ATR72-33-1043, Revision 01, dated January 26, 2016; as the appropriate sources of service information for doing the EPSU inspection and corrective actions. We have revised paragraph (g) of this AD to refer to ATR Service Bulletin ATR42-33-0050, Revision 03, dated May 25, 2016; and ATR Service Bulletin ATR72-33-1043, Revision 03, dated July 20, 2016; as the appropriate sources of service information for accomplishing the required actions. We have also revised paragraph (k) of this AD to provide credit for the actions required by paragraph (g) of this AD if those actions were performed before the effective date of this AD using the service information identified in paragraphs (k)(1) through (k)(6) of this AD. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 ATR has issued Service Bulletin ATR42-33-0050, Revision 03, dated May 25, 2016; and ATR Service Bulletin ATR72-33-1043, Revision 03, dated July 20, 2016. This service information describes procedures for inspecting an EPSU to determine the part number, serial number, and amendment level, and replacing the EPSU. These documents are distinct since they apply to different airplane models. Cobham Aerospace Communications has issued COBHAM Service Bulletin 301-3100-33-002, Revision 3, dated July 30, 2015, which describes procedures for modifying an EPSU by replacing the printed circuit board. 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. Costs of Compliance We estimate that this AD affects 11 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection........................ 1 work-hour x $85 per $0 $85 per EPSU (4 EPSUs $3,740 hour = $85 per EPSU. per airplane). ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary replacements that will be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement........................... 1 work-hour x $85 per hour = Not available........... $85 $85 per EPSU. ---------------------------------------------------------------------------------------------------------------- According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 above, I certify that this AD: 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); [[Page 23496]] 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.
