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 certain The Boeing Company Model 757–200 series airplanes. The NPRM published in the Federal Register on June 8, 2017 (82 FR 26617). The NPRM was prompted by a report indicating that the MCD forward-most cam latch on the forward center cam E:\FR\FM\20DER1.SGM 20DER1 Federal Register / Vol. 82, No. 243 / Wednesday, December 20, 2017 / Rules and Regulations latch pair broke during flight. The NPRM proposed to require repetitive inspections for discrepancies of cam latches, latch pins, and latch pin cross bolts of the MCD; replacement of all alloy steel latch pin cross bolts with CRES latch pin cross bolts of the MCD; and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct discrepancies of the MCD cam latches, latch pins, and latch pin cross bolts, which, if left undetected, could reduce the structural integrity of the MCD and result in potential loss of the cargo door and rapid decompression of the airplane. Comments We gave the public the opportunity to participate in developing this final rule. We have considered the comments received. Air Line Pilots Association, International, FedEx Express, and VT Mobile Aerospace Engineering Inc. supported the NPRM. Conclusion We 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. 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 VT Mobile Aerospace Engineering Inc. Service Bulletin 60301 MAE757SF–SB–52–12/02, Revision 3, dated July 22, 2016. This service information describes procedures for doing inspections for discrepancies of cam latches, latch pins, and latch pin cross bolts of the MCD; replacement of all alloy steel latch pin cross bolts with CRES latch pin cross bolts of the MCD; and related investigative and corrective actions. 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 119 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Inspections Labor cost 20 work-hours × $85 per hour = $1,700 per inspection cycle We estimate the following costs to do any necessary replacement of latch pin cross bolts and related investigative and Cost per product Parts cost $0 Cost on U.S. operators $1,700 per inspection cycle corrective actions that would be required based on the results of the inspection. We have no way of $202,300 per inspection cycle. determining the number of aircraft that might need these actions: ON-CONDITION COSTS Action Labor cost Parts cost Cost per product ethrower on DSK3G9T082PROD with RULES Replacement and Related investigative and corrective actions Up to 144 work-hours × $85 per hour = $12,240 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. (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. Regulatory Findings Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. VerDate Sep<11>2014 16:19 Dec 19, 2017 Jkt 244001 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, PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 Up to $3,000 Up to $15,240.

by a report indicating that the main cargo door (MCD) forward-most cam 
latch on the forward center cam latch pair broke during flight. This AD 
requires repetitive inspections for discrepancies of cam latches, latch 
pins, and latch pin cross bolts of the MCD; replacement of all alloy 
steel latch pin cross bolts with corrosion-resistant steel (CRES) latch 
pin cross bolts of the MCD; and related investigative and corrective 
actions if necessary. We are issuing this AD to address the unsafe 
condition on these products.

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 certain The Boeing Company 
Model 757-200 series airplanes. The NPRM published in the Federal 
Register on June 8, 2017 (82 FR 26617). The NPRM was prompted by a 
report indicating that the MCD forward-most cam latch on the forward 
center cam

[[Page 60301]]

latch pair broke during flight. The NPRM proposed to require repetitive 
inspections for discrepancies of cam latches, latch pins, and latch pin 
cross bolts of the MCD; replacement of all alloy steel latch pin cross 
bolts with CRES latch pin cross bolts of the MCD; and related 
investigative and corrective actions if necessary.
    We are issuing this AD to detect and correct discrepancies of the 
MCD cam latches, latch pins, and latch pin cross bolts, which, if left 
undetected, could reduce the structural integrity of the MCD and result 
in potential loss of the cargo door and rapid decompression of the 
airplane.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We have considered the comments received. Air Line 
Pilots Association, International, FedEx Express, and VT Mobile 
Aerospace Engineering Inc. supported the NPRM.

Conclusion

    We 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. 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 VT Mobile Aerospace Engineering Inc. Service Bulletin 
MAE757SF-SB-52-12/02, Revision 3, dated July 22, 2016. This service 
information describes procedures for doing inspections for 
discrepancies of cam latches, latch pins, and latch pin cross bolts of 
the MCD; replacement of all alloy steel latch pin cross bolts with CRES 
latch pin cross bolts of the MCD; and related investigative and 
corrective actions. 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 119 airplanes of U.S. registry.
    We estimate the following costs to comply with 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.
    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

    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.

 (d) Subject

    Air Transport Association (ATA) of America Code 52, Doors.

 (e) Unsafe Condition

    This AD was prompted by a report indicating that the main cargo 
door (MCD) forward-most cam latch on the forward center cam latch 
pair broke during flight. We are issuing this AD to detect and 
correct discrepancies of the MCD cam latches, latch pins, and latch 
pin cross bolts, which, if left undetected, could reduce the 
structural integrity of the MCD and result in potential loss of the 
MCD and rapid decompression of the airplane.

 (f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

 (g) Repetitive Inspections, Replacement, and Related Investigative and 
Corrective Actions

    At the applicable time specified in paragraph I.D., 
``Compliance,'' of VT Mobile Aerospace Engineering Inc. Service 
Bulletin MAE757SF-SB-52-12/02, Revision 3, dated July 22, 2016 (``SB 
MAE757SF-SB-52-12/02, R3''), except as required by paragraph (h)(1) 
of this AD; or within 30 days after the effective date of this AD, 
whichever occurs later: Do the actions specified in paragraphs 
(g)(1) through (g)(4) of this AD, and do all applicable related 
investigative and corrective actions, in accordance with the 
Accomplishment Instructions of SB MAE757SF-SB-52-12/02, R3, except 
as specified in paragraph (h)(2) of this AD. Do all applicable 
related investigative and corrective actions before further flight.
