SUPPLEMENTARY INFORMATION: Discussion The FAA 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 DC–10–10 and DC–10–10F airplanes, Model DC–10–15 airplanes, Model DC– 10–30 and DC–10–30F (KC–10A and KDC–10) airplanes, Model DC–10–40 and DC–10–40F airplanes, Model MD– 10–10F and MD–10–30F airplanes, and Model MD–11 and MD–11F airplanes. The NPRM published in the Federal Register on August 25, 2020 (85 FR 52287). The NPRM was prompted by reports of cracked floor beams and floor beam supports in the area of the overwing exit doors located at certain STA. The NPRM proposed to require an inspection of the overwing floor beams for any repair, repetitive inspections of the overwing floor beams and floor beam supports at certain STA on the left and right sides for any crack, and applicable on-condition actions. The FAA is issuing this AD to address potential undetected overwing floor beam cracks that could grow in length until the floor beam severs, and, if limit load is applied with two adjacent severed floor beams, could adversely affect the structural integrity of the airplane, which could result in the loss of primary control systems and lead to reduced controllability of the airplane. Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA has considered the comments received. Boeing and Shawn Darr indicated support for the NPRM. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has 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 The FAA reviewed Boeing Alert Requirements Bulletin DC10–53A184 RB, dated February 6, 2020; and Boeing Alert Requirements Bulletin MD11– 53A088 RB, dated March 6, 2020. The service information describes procedures for a general visual inspection of the overwing floor beams for any repair; repetitive eddy current high frequency (ETHF) inspections of the overwing floor beams and floor beam supports for cracks, or repetitive ETHF inspections of the overwing floor beams and detailed inspections of the overwing floor beam supports at certain stations on the left and right sides for any crack, depending on configuration; and applicable on-condition actions. On-condition actions include repair. 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. Costs of Compliance The FAA estimates that this AD affects 224 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost General visual inspection ....... 1 work-hour × $85 per hour = $85. Up to 70 work-hours × $85 per hour = Up to $5,950 per inspection cycle. ETHF and detailed inspections. The FAA estimates the following costs to do any necessary on-condition Parts cost Cost per product $0 0 Cost on U.S. operators $85 ......................................... $19,040. Up to $5,950 per inspection cycle. Up to $1,332,800 per inspection cycle. actions that would be required. The FAA has no way of determining the number of aircraft that might need these on-condition actions: jbell on DSKJLSW7X2PROD with RULES ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Up to 375 work-hours × $85 per hour = Up to $31,875 .... Up to $190,576 ..................................................................

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain RRD Tay 611–8C model turbofan engines. The NPRM published in the Federal Register on May 6, 2019 (84 FR 19745). The NPRM was prompted by reports of LPC rotor blade retention lug failures. In the NPRM, the FAA proposed to require a determination of the number of DFL reapplications that have been applied to the LPC rotor blades and, depending on the number of DFL re-applications, replacement of LPC rotor blades. The FAA is issuing this AD to address the unsafe condition on these products. The European Aviation Safety Agency (EASA), which is the Technical Agent PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 for the Member States of the European Community, has issued EASA AD 2018– 0055, dated March 12, 2018 (referred to after this as ‘‘the MCAI’’), to address the unsafe condition on these products. The MCAI states: The airworthiness limitations for the Tay 611–8C engines, which are approved by EASA, are currently defined and published in the ALS. Among others, the ALS contains limitation(s) applicable to the maximum number of Dry Film Lubrication (DFL) treatments applied on fan blade retention lugs. These instructions have been identified as mandatory for continued airworthiness. Failure to accomplish these instructions could result in an unsafe condition. In addition to the ALS, RRD issued the NMSB to provide alternative methods to establish, in case this cannot be determined from the engine maintenance records, the number of DFL treatments that have been applied to an engine. You may obtain further information by examining the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA–2019–0213. Comments The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Modify Applicability NetJets Aviation (NJA) requested that engines which have incorporated the 12,000 cycle life limit on LPC rotor blade, part number JR58319, per the Airworthiness Limitations section 05– 10–01–870–002, chapter 05–10–01, Rolls-Royce (RR) Tay Propulsion System Time Limits Manual, be excluded from the applicability of this AD. The FAA disagrees because the low cycle fatigue life limit of 12,000 cycles for the LPC rotor blade is a separate requirement from the requirement of this AD to also limit the number of dry film lubricant re-applications. Comment Regarding DFL Reapplication Limit NJA noted that dry film re-application is only accomplished in an engine overhaul shop, and the 12 DFLapplication limit every 1,300 cycles will not be exceeded if the life limit is being tracked. The FAA disagrees. The FAA notes that there are tasks in the Aircraft Maintenance Manual (AMM) for DFL reapplications that are not limited to shop visits. Therefore, this AD is necessary to address those cases in which the AMM DFL re-application tasks are necessary and the engine is not in the shop. This AD requires that when a complete E:\FR\FM\13NOR1.SGM 13NOR1

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA 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 DC-10-10 and DC-10-10F airplanes, Model DC-10-15 airplanes, Model 
DC-10-30 and DC-10-30F (KC-10A and KDC-10) airplanes, Model DC-10-40 
and DC-10-40F airplanes, Model MD-10-10F and MD-10-30F airplanes, and 
Model MD-11 and MD-11F airplanes. The NPRM published in the Federal 
Register on August 25, 2020 (85 FR 52287). The NPRM was prompted by 
reports of cracked floor beams and floor beam supports in the area of 
the overwing exit doors located at certain STA. The NPRM proposed to 
require an inspection of the overwing floor beams for any repair, 
repetitive inspections of the overwing floor beams and floor beam 
supports at certain STA on the left and right sides for any crack, and 
applicable on-condition actions.
    The FAA is issuing this AD to address potential undetected overwing 
floor beam cracks that could grow in length until the floor beam 
severs, and, if limit load is applied with two adjacent severed floor 
beams, could adversely affect the structural integrity of the airplane, 
which could result in the loss of primary control systems and lead to 
reduced controllability of the airplane.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA has considered the comments 
received. Boeing and Shawn Darr indicated support for the NPRM.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has 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

    The FAA reviewed Boeing Alert Requirements Bulletin DC10-53A184 RB, 
dated February 6, 2020; and Boeing Alert Requirements Bulletin MD11-
53A088 RB, dated March 6, 2020. The service information describes 
procedures for a general visual inspection of the overwing floor beams 
for any repair; repetitive eddy current high frequency (ETHF) 
inspections of the overwing floor beams and floor beam supports for 
cracks, or repetitive ETHF inspections of the overwing floor beams and 
detailed inspections of the overwing floor beam supports at certain 
stations on the left and right sides for any crack, depending on 
configuration; and applicable on-condition actions. On-condition 
actions include repair. 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.

Costs of Compliance

    The FAA estimates that this AD affects 224 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
