Background

    The FAA issued AD 2020-01-18, Amendment 39-19824 (85 FR 5304, 
January 30, 2020); corrected February 26, 2020 (85 FR 10969) (AD 2020-
01-18), for all the Boeing Company Model 757 airplanes. AD 2020-01-18 
requires revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations. AD 2020-01-18 includes a requirement to revise the 
existing maintenance or inspection program to incorporate a 
supplemental program to address the effect of Supplemental Type 
Certificate (STC) ST01518SE. The FAA issued AD 2020-01-18 to address 
fatigue cracking of the principal structural elements, which could 
adversely affect the structural integrity of the airplane.
    Since the FAA issued AD 2020-01-18, the FAA has received an 
operator report indicating that during a maintenance H-check 
inspection, a crack was found at the splice fitting between the 
original wing and the Aviation Partners Boeing (APB) modified lower 
wing skin panel, which is spliced at wing station (WS) 711 on a Boeing 
Company Model 757-200 airplane with the APB blended winglets installed 
in accordance with STC ST01518SE. APB reviewed the crack finding and 
determined the existing airworthiness limitations (AWL) structural 
significant items (SSI) 57-20-

[[Page 43160]]

32B does not provide adequate probability of detection for foreseeable 
fatigue cracking of SSIs at station WS 711. If cracks grow undetected, 
it may result in the inability of a principal structural element to 
sustain limit loads. The FAA has determined that it is necessary to 
revise the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations for 
The Boeing Company Model 757-200 and -300 airplanes that have been 
modified in accordance with STC ST01518SE, with or without blended or 
scimitar blended winglets installed. Incorporating the revision 
required by this proposed AD would terminate the requirements of 
paragraphs (g) and (h)(2) of AD 2020-01-18.
    The FAA is proposing this AD to address the potential for fatigue 
cracking on the wing and winglet. This condition, if not addressed, 
could result in the inability of a principal structural element to 
sustain limit loads, which could adversely affect the structural 
integrity of the airplane.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Aviation Partners Boeing AP57.2-0604.2 Supplement 
to D622N001-9 (September 2020) 757 Maintenance Planning Data (MPD) 
document, Section 9, Airworthiness Limitations (AWLs) and Certification 
Requirements (CMRs) Boeing 757-200 with Winglets FAA STC NUMBER

STC NUMBER ST01518SE AND EASA STC NUMBER 10015659, Revision August 
2022. This material specifies airworthiness limitations for structural 
inspections, structural safe life parts, systems, and certification 
maintenance requirements.
    The FAA also reviewed Aviation Partners Boeing AP57.2-0604.2-DTR 
Supplement to D622N001-DTR (October 2018) 757 Damage Tolerance Rating 
(DTR) Check Form Document for Boeing 757-200 with Winglets FAA STC

Blended Winglets FAA STC NUMBER ST01518SE AND EASA STC NUMBER 10015659, 
Revision August 2023. This material provides the DTR check forms and 
the procedure for their use.
    This material 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.

Proposed AD Requirements in This NPRM

    This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. This proposed AD would also 
require sending inspection results to Aviation Partners Boeing.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(j) of this proposed AD.

Differences Between This Proposed AD and the Service Information

    This proposed AD would require that the reports specified in the 
service information identified in paragraph (g) of this proposed AD be 
submitted within 10 days after the airplane is returned to service, 
instead of 10 days after each individual finding as specified in the 
documents. The FAA has included this grace period in paragraph (g)(3) 
of this proposed AD.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 156 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate. Therefore, the FAA estimates the average total cost per 
operator to be $7,650 (90 work-hours x $85 per work-hour).

                                               On-Condition Costs

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 a 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 currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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

[[Page 43161]]

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 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.
