We will also post a report summarizing each substantive verbal contact we receive about this NPRM. 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 2017-0239, dated November 30, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all 328 Support Services GmbH Model 328-100 and -300 airplanes. The MCAI states: Occurrences were reported on horizontal stabilizer bearing supports being found corroded at the contact surface to the horizontal stabilizer rear spar. The corroded area was at the lower flange position, which is connected to the stabilizer rear spar and not visible without detachment of the fitting. Investigation determined that the corrosion is triggered by galvanic effect, due to a direct contact between the horizontal stabilizer rear spar, made from CFRP (carbon fibre reinforced plastic), and the aluminium rear attachment fitting. This condition, if not detected and corrected, could lead to failure of the fitting and loss of one load path of the horizontal stabilizer attachment, possibly resulting in reduced control of the aeroplane. To address this potential unsafe condition, 328 Support Services GmbH (328 SSG) issued Service Bulletin (SB) SB-328-55-557 and SB- 328J-55-324 to provide instructions for inspection of the affected area, replacement of the parts, and modification to improve corrosion behaviour by incorporating of glass fibre layer. For the reasons described above, this [EASA] AD requires a one- time inspection [detailed visual inspection and an eddy current inspection for chafing and corrosion] of the horizontal stabilizer rear bearing supports, and, depending on findings, accomplishment of applicable corrective action(s) [replacement of the affected horizontal stabilizer rear bearing supports]. This [EASA] AD also requires a modification of the horizontal stabilizer rear spar, irrespective of findings. You may examine the MCAI in the AD docket on the internet at http:/ / [[Page 26390]] www.regulations.gov by searching for and locating Docket No. FAA-2018- 0503. Related Service Information Under 1 CFR Part 51 328 Support Services GmbH has issued Service Bulletin SB-328-55- 557, Revision 1, dated February 1, 2018; and Service Bulletin SB-328J- 55-324, Revision 1, dated February 1, 2018. This service information describes a detailed visual inspection and an eddy current inspection for corrosion and any other damage (i.e., cracking and chafing) of the horizontal stabilizer rear bearing supports, modification of the horizontal stabilizer rear spar, and replacement of the affected horizontal stabilizer rear bearing supports if necessary. These documents are distinct since they apply to different airplane models. 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 27 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 ---------------------------------------------------------------------------------------------------------------- Detailed visual inspection and eddy 4 work-hours x $85 per $0 $340 $9,180 current inspection. hour = $340. Modification.......................... 16 work-hours x $85 per 0 1,360 36,720 hour = $1,360. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary replacement that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need this replacement: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement................................... 24 work-hours x $85 per hour = (*) $2,040 $2,040. ---------------------------------------------------------------------------------------------------------------- * We have received no definitive data that would enable us to provide part cost estimates for the on-condition action specified in this proposed AD. 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. 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 1.
