ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model MD-90-30 airplanes. This AD was prompted by a report of cracking in a horizontal stabilizer rear spar cap. This AD requires repetitive inspections for any crack in the left and right side horizontal stabilizer rear spar upper caps, and repair or replacement if necessary. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective June 27, 2017. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 27, 2017. ADDRESSES: For service information identified in this final rule, contact Boeing Commercial Airplanes, Attention: Contractual & Data Services (C&DS), 2600 Westminster Blvd., MC 110-SK57, Seal Beach, CA 90740-5600; telephone 562-797-1717; Internet https://www.myboeingfleet.com.

FOR FURTHER INFORMATION CONTACT: James Guo, Aerospace Engineer, Airframe Branch, ANM-120L, FAA, Los Angeles Aircraft Certification Office (ACO), 3960 Paramount Boulevard, Lakewood, CA 90712-4137; phone: 562-627-5357; fax: 562-627-5210; email: [email protected]. SUPPLEMENTARY INFORMATION: [[Page 23505]] Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all The Boeing Company Model MD-90-30 airplanes. The NPRM published in the Federal Register on December 5, 2016 (81 FR 87499). The NPRM was prompted by a report of cracking in an MD-90 horizontal stabilizer rear spar cap at station XE5.931. The NPRM proposed to require repetitive open hole eddy current high frequency (ETHF) or surface eddy current low frequency (ETLF) inspections for any crack in the left and right side horizontal stabilizer rear spar upper caps, and repair or replacement if necessary. We are issuing this AD to detect and correct fatigue cracking of the horizontal stabilizer rear spar upper cap, which could adversely affect the structural integrity of the airplane. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment. Support for the NPRM Boeing stated that it supports the NPRM. Request To Allow Installation of a Serviceable Spare as a Corrective Action Delta Airlines requested that we allow installation of a qualified serviceable spare horizontal stabilizer as a corrective action in lieu of repairing or replacing the horizontal stabilizer. Delta noted that this type of corrective action has been approved as an alternative method of compliance (AMOC) for other ADs affecting the horizontal stabilizer. We disagree with the request. While an AMOC has been previously granted to allow applicants to replace an unserviceable stabilizer with a serviceable stabilizer, each such AMOC approval required the applicant to demonstrate that they had a sufficient program in place to trace, document, inspect, and install the serviceable horizontal stabilizers. The details of such a program cannot be prescribed and documented within an AD. However, we will consider requests for approval of an AMOC under the provisions of paragraph (j) of this AD. Explanation of Change to NPRM We revised paragraph (g) of the proposed AD to refer to the compliance times of both table 1 and table 2 of paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin MD90-55A018, dated June 29, 2016. The reference to table 2 had been inadvertently omitted from the proposed AD. Table 2 specifies the same compliance times as table 1, but table 2 applies to the right side horizontal rear spar upper cap, while table 1 applies to the left side. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the change 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 We reviewed Boeing Alert Service Bulletin MD90-55A018, dated June 29, 2016. The service information describes procedures for repetitive open hole ETHF or surface ETLF inspections for any crack in the left and right side horizontal stabilizer rear spar upper caps common to the elevator hinge fitting at station XE = 5.931, and repair or replacement. 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 105 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..................... 8 work-hours x $85 per $0 $680 per $71,400 per hour = $680 per inspection cycle. inspection cycle. inspection cycle. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary repairs or replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these actions: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Upper cap splice repair or replacement (each 368 work-hours x $85 per hour = $64,306 $95,586 side). $31,280. ---------------------------------------------------------------------------------------------------------------- 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 [[Page 23506]] products identified in this rulemaking action. Regulatory Findings 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 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.
