Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Proposed Rules or inspection program, as applicable, to incorporate the information specified in Boeing 767200/300/300F/400ER
Airworthiness LimitationsLine Number Specific, D622T001902, dated August 2020, is an acceptable method of compliance with paragraph g of this proposed AD for the tasks specified in that document only.

D622T001DTR, dated February 2020.
This service information includes the DTR check forms and the procedure for their use.
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.

Related Service Information Under 1
CFR Part 51
The FAA reviewed the following service information, which describes airworthiness limitations for structural inspections and structural safe life limits among other limitations. These documents are distinct since they apply to different configurations.

The FAA also reviewed Boeing 767

FAAs Determination The FAA is proposing this AD
because the agency 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. Certain changes described above expand the scope of the NPRM. As a result, the FAA has determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM.
Proposed Requirements of This SNPRM
This SNPRM would require revising the existing maintenance or inspection program, as applicable, to incorporate
new or more restrictive airworthiness limitations. This proposed AD also would require sending the inspection results to Boeing.
Costs of Compliance The FAA estimates that this AD
affects 542 airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the FAA
recognizes that this number may vary from operator to operator. In the past, the FAA has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleets, the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the FAA estimates the total cost per operator to be $7,650
90 work-hours $85 per work-hour.

Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this proposed AD is 2120
0056. The paperwork cost associated with this proposed AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this proposed AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to Information Collection Clearance Officer, Federal Aviation Administration, 10101

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 Agencys 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 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 this proposed regulation:
1 Is not a significant regulatory action under Executive Order 12866, 2 Would not affect intrastate aviation in Alaska, and 3 Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
