ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are superseding Airworthiness Directive (AD) 2016-13-06, which applied to certain Saab AB, Saab Aeronautics Model 340A (SAAB/ SF340A) and SAAB 340B airplanes. AD 2016-13-06 required a revision of the applicable airplane flight manual (AFM), repetitive inspections of the horizontal stabilizer de-icing boots, and applicable corrective actions. This AD continues to require a revision of the applicable AFM, repetitive inspections of the horizontal stabilizer de-icing boots, and applicable corrective actions. This AD also requires replacement of single stitched de-icing boots with improved double stitched boots, and re-identification of the modified horizontal stabilizer leading edge. This AD was prompted by reports of ruptured horizontal stabilizer de- icing boots. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 18, 2018. [[Page 46378]] The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 18, 2018.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2016-13-06, Amendment 39-18570 (81 FR 41432, June 27, 2016) (``AD 2016-13-06''). AD 2016-13-06 applied to certain Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) and SAAB 340B airplanes. The NPRM published in the Federal Register on April 17, 2018 (83 FR 16792). The NPRM was prompted by reports of ruptured horizontal stabilizer de-icing boots. The NPRM proposed to continue to require a revision of the applicable AFM, repetitive inspections of the horizontal stabilizer de-icing boots, and applicable corrective actions. The NPRM also proposed to require replacement of single stitched de-icing boots with improved double stitched boots, and re- identification of the modified horizontal stabilizer leading edge. We are issuing this AD to detect and correct ruptured horizontal stabilizer de-icing boots, which could lead to complete loss of the de- icing function within its associated zone and severe vibrations, possibly resulting in reduced control of the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017-0144, dated August 9, 2017 (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) and SAAB 340B airplanes. The MCAI states: Several occurrences were reported of rupture of the horizontal stabilizer de-icing boot in flight. In some of the reported events, the de-icing boot had formed a large open scoop. This condition, if not detected and corrected, could lead to complete loss of the de-icing function within its associated zone and severe vibrations, possibly resulting in reduced control of the aeroplane. To address this potential unsafe condition, Saab AB, Aeronautics (hereafter referred to as ``Saab'' in this [EASA] AD) issued Alert Operations Bulletin (AOB) No. 12 and AOB No. 23 as temporary measures, recommending to select Flaps 0 for landing in the event of a suspected rupture of the deicing boot on the horizontal stabilizer. In addition, Saab issued SB [Service Bulletin] 340-30- 094 providing instructions for inspection of de-icing boots. Consequently, EASA issued AD 2015-0129 [which corresponds to FAA AD 2016-13-06] to require amendment of the applicable Aircraft Flight Manual (AFM), repetitive inspections of the horizontal stabilizer deicing boots and, depending on findings, accomplishment of applicable corrective action(s). Since that [EASA] AD was issued, Saab developed an improved de- icing boot, reinforced through double stitch lines, and issued SB 340-30-095 providing instructions for boot replacement. For the reason described above, this [EASA] AD retains the requirements of EASA AD 2015-0129, which is superseded, and requires replacement of single stitched deicing boots, installed on the left- hand (LH) and right-hand (RH) horizontal stabilizer, with improved double stitched boots, and reidentification of the modified horizontal stabilizer leading edge. 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-2018- 0271. Comments We gave the public the opportunity to participate in developing this final rule. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 Saab AB, Saab Aeronautics has issued the following service information. Service Bulletin 340-30-094, dated March 27, 2015. This service information describes procedures for repetitive detailed inspections of the de-icing boots installed on the horizontal stabilizers, and repair and replacement of damaged de-icing boots. Service Bulletin 340-30-095, dated April 3, 2017. This service information describes procedures for replacement of single stitched de-icing boots with improved double stitched boots, and re- identification of the modified horizontal stabilizer leading edge. Saab AB, Saab Aeronautics has also issued the following AFMs, which describe performance limitations and general data. These AFMs are distinct since they apply to different airplane models in different configurations. AFM 340A 001, Revision 57, dated March 27, 2015. AFM 340B 001, Revision 35, dated March 27, 2015. AFM 340B 010, Revision 28, dated March 27, 2015. 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 51 airplanes of U.S. registry. The actions required by AD 2016-13-06, and retained in this AD take about 6 work-hours per product, at an average labor rate of $85 per workhour. Based on these figures, the estimated cost of the actions that are required by AD 2016-13-06 is $510 per product. [[Page 46379]] In addition, we estimate that any necessary follow-on actions required by AD 2016-13-06, and retained in this AD take about 6 work- hours and require parts costing $9,500, for a cost of $10,010 per product. We have no way of determining the number of aircraft that might need these actions. We also estimate that it would take about 6 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $13,500 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $714,510, or $14,010 per product. 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 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 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); 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. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
