ACTION: Proposed rule; withdrawal. AGENCY: The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to certain The Boeing Company Model 787–8 and 787–9 airplanes. The NPRM was prompted by a report that a passenger entry door assist handle became detached during use. The NPRM would have required a detailed inspection of all passenger and service entry door assist handles for correct installation and applicable oncondition actions. Since issuance of the NPRM, we determined that the service information is ineffective in addressing the unsafe condition and must be revised. Accordingly, the NPRM is withdrawn. SUMMARY: The FAA is withdrawing the proposed rule published July 15, 2019 (84 FR 33710), as of March 30, 2020.

SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 17:24 Mar 27, 2020 Jkt 250001 Discussion The FAA issued an NPRM that proposed to amend 14 CFR part 39 by adding an AD that would apply to the specified products. The NPRM was published in the Federal Register on July 15, 2019 (84 FR 33710). The NPRM was prompted by a report that a passenger entry door assist handle became detached during use. An investigation found that incorrect installation of the door assist handle is possible due to the handle insert giving a false indication of correct installation. The NPRM proposed to require a detailed inspection of all passenger and service entry door assist handles for correct installation and applicable oncondition actions. The proposed actions were intended to address the possibility of an incorrectly installed door assist handle becoming detached and unavailable to use during door operation or airplane egress, which could cause injury to passengers, flightcrew, or maintenance personnel. Actions Since the NPRM Was Issued Since issuance of the NPRM, Boeing has informed the FAA that the root cause determination has changed. The unsafe condition still exists but the proposed service information is ineffective in correcting it, therefore it is necessary to completely revise the service information to address the root cause. Withdrawal of the NPRM constitutes only such action and does not preclude the FAA from further rulemaking on this issue, nor does it commit the FAA to any course of action in the future. FAA’s Conclusions Upon further consideration, the FAA has determined that the NPRM does not adequately address the identified unsafe condition. Accordingly, the NPRM is withdrawn. Regulatory Findings Since this action only withdraws an NPRM, it is neither a proposed nor a final rule. This action therefore is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Withdrawal Accordingly, the notice of proposed rulemaking, Docket No. FAA–2019– 0518, which was published in the PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 Federal Register on July 15, 2019 (84 FR 33710), is withdrawn. Issued on March 24, 2020. Gaetano A. Sciortino, Deputy Director for Strategic Initiatives, Compliance & Airworthiness Division, Aircraft Certification Service.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2015–13–06, which applies to certain The Boeing Company Model 747–400 and 747–400F series airplanes. AD 2015–13–06 requires repetitive inspections of the longeron extension fittings for cracking, repetitive high frequency eddy current (HFEC) inspections of any modified, repaired, or replaced longeron extension fitting for cracking, and applicable oncondition actions. Since the FAA issued AD 2015–13–06, the FAA has determined that additional airplanes are affected by the identified unsafe condition. This proposed AD would retain the requirements of AD 2015–13– 06 and include additional airplanes in the applicability.

SUPPLEMENTARY INFORMATION: Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2020–0208; Product Identifier 2019–NM–209–AD’’ at the beginning of your comments. The FAA specifically invites comments on the Discussion The FAA issued AD 2015–13–06, Amendment 39–18193 (80 FR 44835, July 28, 2015) (‘‘AD 2015–13–06’’), for certain The Boeing Company Model 747–400 and 747–400F series airplanes. AD 2015–13–06 requires repetitive inspections of the longeron extension fittings for cracking, repetitive HFEC inspections of any modified, repaired, or replaced longeron extension fitting for cracking, and applicable oncondition actions. AD 2015–13–06 resulted from reports of cracking in the outboard flange of the longeron extension fittings, and the FAA’s determination that more work is necessary on airplanes on which a permanent repair, longeron extension fitting replacement, or modification was accomplished. The FAA issued AD 2015–13–06 to address cracks in the longeron extension fittings, which can become large and adversely affect the structural integrity of the airplane. Actions Since AD 2015–13–06 Was Issued Since the FAA issued AD 2015–13– 06, Boeing reported that an operator found a cracked longeron extension fitting on an airplane not included in the applicability of AD 2015–13–06. Based on that report, the FAA has determined that additional airplanes are likely affected by the identified unsafe condition. The FAA has therefore added Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–200C, 747–200F, 747–300, 747–400D, 747SR, and 747SP series airplanes to the applicability of this proposed AD. 17511 Related Service Information Under 1 CFR Part 51 The FAA reviewed Boeing Service Bulletin 747–53A2860, Revision 3, dated November 11, 2019. The service information describes procedures for repetitive inspections of the longeron extension fittings for cracking, repetitive HFEC inspections of any modified, repaired, or replaced longeron extension fitting for cracking, and applicable oncondition actions. On-condition actions include replacement, repair, and modification. 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 The FAA is proposing this AD because the FAA evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements Although this proposed AD does not explicitly restate the requirements of AD 2015–13–06, this proposed AD would retain all of the requirements of AD 2015–13–06. Those requirements are referenced in the service information identified previously, which, in turn, is referenced in paragraph (g) of this proposed AD. This proposed AD would include additional airplanes in the applicability. This proposed AD would also require accomplishing the actions specified in the service information described previously. For information on the procedures and compliance times, see this service information at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–0208. Costs of Compliance The FAA estimates that this proposed AD affects 67 airplanes of U.S. registry.

Up to 908 work-hours × $85 per hour = Up to $77,180. Up to $99,950 ............................... 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. The FAA is 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. lotter on DSKBCFDHB2PROD with PROPOSALS Regulatory Findings The FAA has 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 that the proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) 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: VerDate Sep<11>2014 17:24 Mar 27, 2020 Jkt 250001 Cost per product Up to $177,130.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2015-13-06, which applies to certain The Boeing Company Model 747-400 
and 747-400F series airplanes. AD 2015-13-06 requires repetitive 
inspections of the longeron extension fittings for cracking, repetitive 
high frequency eddy current (HFEC) inspections of any modified, 
repaired, or replaced longeron extension fitting for cracking, and 
applicable on-condition actions. Since the FAA issued AD 2015-13-06, 
the FAA has determined that additional airplanes are affected by the 
identified unsafe condition. This proposed AD would retain the 
requirements of AD 2015-13-06 and include additional airplanes in the 
applicability. For those additional airplanes, this proposed AD would 
require only repetitive inspections of the longeron extension fittings 
for cracking and repair if necessary. The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by May 14, 
2020.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The FAA issued AD 2015-13-06, Amendment 39-18193 (80 FR 44835, July 
28, 2015) (``AD 2015-13-06''), for certain The Boeing Company Model 
747-400 and 747-400F series airplanes. AD 2015-13-06 requires 
repetitive inspections of the longeron extension fittings for cracking, 
repetitive HFEC inspections of any modified, repaired, or replaced 
longeron extension fitting for cracking, and applicable on-condition 
actions. AD 2015-13-06 resulted from reports of cracking in the 
outboard flange of the longeron extension fittings, and the FAA's 
determination that more work is necessary on airplanes on which a 
permanent repair, longeron extension fitting replacement, or 
modification was accomplished. The FAA issued AD 2015-13-06 to address 
cracks in the longeron extension fittings, which can become large and 
adversely affect the structural integrity of the airplane.

Actions Since AD 2015-13-06 Was Issued

    Since the FAA issued AD 2015-13-06, Boeing reported that an 
operator found a cracked longeron extension fitting on an airplane not 
included in the applicability of AD 2015-13-06. Based on that report, 
the FAA has determined that additional airplanes are likely affected by 
the identified unsafe condition. The FAA has therefore added Model 747-
100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 
747-400D, 747SR, and 747SP series airplanes to the applicability of 
this proposed AD.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Service Bulletin 747-53A2860, Revision 3, 
dated November 11, 2019. The service information describes procedures 
for repetitive inspections of the longeron extension fittings for 
cracking, repetitive HFEC inspections of any modified, repaired, or 
replaced longeron extension fitting for cracking, and applicable on-
condition actions. On-condition actions include replacement, repair, 
and modification. 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

    The FAA is proposing this AD because the FAA evaluated all the 
relevant information and determined the unsafe condition described 
previously is likely to exist or develop in other products of the same 
type design.

Proposed AD Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2015-13-06, this proposed AD would retain all of the 
requirements of AD 2015-13-06. Those requirements are referenced in the 
service information identified previously, which, in turn, is 
referenced in paragraph (g) of this proposed AD. This proposed AD would 
include additional airplanes in the applicability. This proposed AD 
would also require accomplishing the actions specified in the service 
information described previously. For information on the procedures and 
compliance times, see this service information at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0208.

Costs of Compliance

    The FAA estimates that this proposed AD affects 67 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required. The FAA has no way of 
determining the number of aircraft that might need these on-condition 
actions:

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.
    The FAA is 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

    The FAA has 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 that the proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) 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
