ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 747-400, 747-400D, and 747-400F airplanes. This AD was prompted by a report of a crack in the left wing front spar web, found following a fuel leak. This AD requires repetitive inspections for cracking of the front spar web, and repairs 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.

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 all The Boeing Company Model 747-400, 747-400D, and 747-400F airplanes. The NPRM published in the Federal Register on December 2, 2016 (81 FR 86977) (``the NPRM''). The NPRM was prompted by a report indicating that a fuel leak in one airplane led to the discovery of a 13.4-inch crack in the left wing front spar web inboard of pylon number 2 between front spar station inboard (FSSI) 655.75 and FSSI 660. The NPRM proposed to require repetitive detailed, ultrasonic, and high frequency eddy current inspections for cracking of the front spar web between FSSI 628 and FSSI 713, and repairs if necessary. We are issuing this AD to detect and correct cracking in the front spar web, which could lead to fuel leaks and a consequent fire. 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 and commenter Melanie Smith stated that they support the NPRM. Request To Update the Labor Costs British Airways (BA), Cargolux Airlines (CLX), and KLM Royal Dutch Airlines (KLM) all stated that the actual work-hours required to do the mandated inspections are higher than the estimate listed in the NPRM. They estimated the inspections actually take between 137 and 159 work- hours, not the 55 work-hours stated in the NPRM. We agree that the estimated work-hours should be increased. When issuing a service bulletin, Boeing estimates work-hours under expected conditions. As operators implement the service bulletin, they may find the actual work-hours are higher or lower than estimated. We have updated the Costs of Compliance section of this AD to reflect a conservative estimate of 159 work-hours per inspection cycle. Request To Change the Initial and Repetitive Compliance Times BA, CLX, and KLM all requested that we change the initial and/or repetitive compliance times to align with scheduled maintenance checks. BA proposed to do time-limited alternative inspections in the most critical web locations and to defer the majority of the web inspections to coincide with longer planned maintenance checks. CLX requested that we change the initial compliance time from 6 months to 24 months, and that we change the repetitive inspection interval from 1,200 flight cycles to 2,000 flight cycles. KLM requested that we extend the repetitive inspection intervals for Model 747 freighters from 1,200 flight cycles to 1,800 flight cycles. Each of the commenters noted that the actual work-hours are higher than estimated in the NPRM, and the inspections would require additional downtime and costs if not done at the same time as regularly scheduled maintenance. None of the commenters provided engineering analyses to support their proposed extended compliance times. We disagree with the requests. In developing an appropriate compliance time for this action, we considered the urgency associated with the subject unsafe condition and the practical aspect of accomplishing the required modification within a period of time that corresponds to the normal scheduled maintenance for most affected operators. Boeing is aware of the discrepancy in work-hours and is developing a request for a global alternative method of compliance (AMOC) to provide operators an alternative for both the areas of inspection and the compliance times. In addition, operators have the option of proposing an adjustment to the compliance times, supported by appropriate engineering analyses, in accordance with the provisions of paragraph (j) of this AD. We have not changed this final rule regarding this issue. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD 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 correcting 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 We reviewed Boeing Alert Service Bulletin 747-57A2357, dated September 12, 2016. The service information describes procedures for repetitive detailed, ultrasonic, and high frequency eddy current inspections, and repairs of cracking of the front spar web between FSSI 628 and FSSI 713. 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 137 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 ---------------------------------------------------------------------------------------------------------------- Inspections...................... 159 work-hours x $0 $13,515 per $1,851,555 per $85 per hour = inspection cycle. inspection cycle. $13,515 per inspection cycle. ---------------------------------------------------------------------------------------------------------------- We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this 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. [[Page 23511]] 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 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.
