Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain The Boeing Company Model 

757–200, –200CB, and –300 series 

airplanes. This proposed AD was 

prompted by a report of cracking found 

in new locations at a certain body 

station (STA) during frame segment 

replacement repairs, including in the 

web at the K-hole between certain 

stringers, in the outer chord above the 

lower hinge intercostal, and in the inner 

chord and web between certain 

stringers. This proposed AD would 

require an inspection or records check 

for the presence of approved or local 

repairs, repetitive eddy current 

inspections for cracking, and applicable 

on-condition actions. 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 March 17, 2025.

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–2025–0012; Project 

Identifier AD–2024–00219–T’’ at the 

beginning of your comments. The most 

helpful comments reference a specific 

portion of the proposal, explain the 

reason for any recommended change, 

and include supporting data. The FAA 

will consider all comments received by 

the closing date and may amend this 

proposal because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to 

regulations.gov, including any personal 

information you provide. The agency 

will also post a report summarizing each 

substantive verbal contact received 

about this NPRM. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Wayne Ha, Aviation 

Safety Engineer, FAA, 2200 South 216th 

St., Des Moines, WA 98198; phone: 

562–627–5238; email: wayne.ha@

faa.gov. Any commentary that the FAA 

receives that is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Background 

The FAA has received a report 

indicating that cracks were found in 

new locations at STA 1640 during frame 

segment replacement repairs, including 

in the web at the K-hole between 

stringer S–9 and S–10, in the outer 

chord above the lower hinge intercostal, 

and in the inner chord and web between 

S–10 and S–19. The existing inspection 

program for the STA 1640 frame is not 

sufficient to detect cracks in these 

locations because most of the frame is 

hidden by adjacent structure that makes 

the maintenance planning data (MPD) 

document inspections inadequate to 

detect cracks before they reach a critical 

size. Additionally, existing ADmandated inspections are at other 

locations. Undetected cracks in the 


ddrumheller on DSK120RN23PROD with PROPOSALS1
Federal Register / Vol. 90, No. 20 / Friday, January 31, 2025 / Proposed Rules 8691 

fuselage frame at STA 1640 could affect 

a principal structural element’s ability 

to sustain limit load. This condition, if 

not addressed, could result in reduced 

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 Boeing Alert 

Requirements Bulletin 757–53A0123 

RB, dated March 13, 2024. This material 

specifies procedures for an inspection or 

records check for the presence of 

approved repairs at STA 1640 frame 

between S–9 and S–19, left and right 

sides, or local repairs at specified 

locations at STA 1640, repetitive eddy 

current inspections for cracking of the 

STA 1640 frame inner chord, web and 

outer chord at specified locations, and 

applicable on-condition actions. Oncondition actions include contacting 

Boeing for repair. 

The FAA also reviewed Aviation 

Partners Boeing Alert Service Bulletin 

AP757–53–006, dated May 7, 2024. This 

material specifies procedures for an 

inspection or records check for the 

presence of approved repairs at STA 

1640 frame between S–9 and S–19, left 

and right sides, or local repairs at 

specified locations at STA 1640, 

repetitive eddy current inspections for 

cracking of the STA 1640 frame inner 

chord, web and outer chord at specified 

locations, and applicable on-condition 

actions. On-condition actions include 

contacting Boeing for repair. 

These documents are distinct since 

they apply to different airplane 

configurations. 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 

accomplishing the actions specified in 

the material already described, except 

for any differences identified as 

exceptions in the regulatory text of this 

proposed AD. For information on the 

procedures and compliance times, see 

Boeing Alert Requirements Bulletin 

757–53A0123, dated March 13, 2024, at 

regulations.gov under Docket No. FAA– 

2025–0012. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 481 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Inspection for presence of repairs.69 work-hours × $85 per hour 

= $5,865.

None ........ $5,865 ..................................... $2,821,065. 

Eddy current inspections .......... Up to 74 work-hours × $85 per 

hour = $6,290 per inspection 

cycle.

None ........ Up to $6,290 per inspection 

cycle.

Up to $3,025,490 per inspection cycle. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the repairs specified in this proposed 

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. 

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. 

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
