rulemaking. 

Background 

The FAA issued an NPRM to amend 

14 CFR part 39 by adding an AD that 

would apply to all The Boeing Company 

Model 757 airplanes. The NPRM 

published in the Federal Register on 

January 26, 2023 (88 FR 4920). The 

NPRM was prompted by the potential 

for cracks to start in hidden areas 

underneath the scuff plates in the 

fuselage skin and bear strap of certain 

doors. In the NPRM, the FAA stated that 

certain maintenance inspections do not 

include a step to remove the scuff 

plates, which contributes to the inability 

to find cracks before they become 

critical. Cracks underneath the scuff 

plates in the fuselage skin and bear 

strap, if not addressed, could adversely 

affect the structural integrity of the 

airplane. 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 171 / Wednesday, September 6, 2023 / Proposed Rules 60905 

In the NPRM, the FAA proposed to 

require a general visual inspection or a 

maintenance records check for repairs 

in the areas around the fuselage skin 

door cutout lower corners of certain 

doors. The FAA also proposed 

applicable on-condition actions 

including repetitive low frequency and 

high frequency eddy current inspections 

for cracks in the skin or bear strap in the 

unrepaired areas, and crack repair. 

Actions Since the NPRM Was Issued 

Based on the comments the FAA 

received on the NPRM, the FAA is 

proposing additional inspections for 

Model 757–200 series airplanes that 

have been modified from a passenger 

configuration to a cargo configuration 

under supplemental type certificate 

(STC) ST04242AT, ST03562AT, or 

ST03952AT. As proposed in the NPRM, 

for Model 757–200 series airplanes with 

STC ST04242AT, ST03562AT, or 

ST03952AT, only the No. 1, No. 2, and 

No. 4 passenger entry doors, and the No. 

1, No. 2, and No. 3 cargo doors, would 

have to be inspected. With this SNPRM, 

the FAA is proposing that for those 

airplanes, the crew entry door and main 

deck cargo door, as applicable, would 

also have to be inspected. This change 

is more fully discussed under the 

Comments section. 

Comments 

The FAA received comments from the 

Air Line Pilots Association, 

International, Boeing, and United 

Airlines, who supported the NPRM 

without change. 

The FAA also received comments 

from Aviation Partners Boeing, VT 

Mobile Aerospace Engineering (VT 

MAE), and Federal Express (FedEx). The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Effect of Winglets on Accomplishment 

of the Proposed Actions 

Aviation Partners Boeing stated that 

the installation of blended or scimitar 

blended winglets per STC ST01518SE 

does not affect compliance with the 

actions in the proposed AD. 

The FAA agrees with the commenter. 

The FAA has redesignated paragraph (c) 

of the proposed AD (of the NPRM) as 

paragraph (c)(1) of this proposed AD (of 

the SNPRM) and added paragraph (c)(2) 

to this proposed AD to state that 

installation of STC ST01518SE does not 

affect the ability to accomplish the 

actions required by this AD. Therefore, 

for airplanes on which STC ST01518SE 

is installed, a ‘‘change in product’’ 

alternative method of compliance 

(AMOC) approval request is not 

necessary to comply with the 

requirements of 14 CFR 39.17. 

Request To Change Required 

Inspections and Compliance Time for 

Airplanes Modified per VT MAE STC 

ST04242AT 

VT MAE requested the FAA change 

the proposed inspections for airplanes 

modified under STC ST04242AT from a 

passenger configuration to a 15-pallet 

cargo configuration. VT MAE stated that 

under STC ST04242AT, the No. 1 left 

hand side (LHS), No. 1 right hand side 

(RHS), No. 4 LHS, and No. 4 RHS 

passenger entry doors have been 

plugged (re-skinned). Thus, the 

commenter requested the FAA not 

require these airplanes to be subject to 

the inspection of the No. 1 LHS, No. 1 

RHS, No. 4 LHS and No. 4 RHS 

passenger entry doors specified in 

Boeing Alert Requirements Bulletin 

757–53A0119 RB, dated October 12, 

2022. In addition, the commenter stated 

that under STC ST04242AT, the crew 

entry door and the main deck cargo door 

surround cutout structure is similar to 

that of Boeing Model 757–200 PF 

airplanes identified as Group 4 in 

Boeing Alert Requirements Bulletin 

757–53A0119 RB, dated October 12, 

2022. As a result, VT MAE requested 

that these airplanes be required to do 

the inspection of the crew entry door 

and main deck cargo door (Table 4 and 

Table 5 of Boeing Alert Requirements 

Bulletin 757–53A0119 RB, dated 

October 12, 2022), that is specified for 

Group 4 airplanes. 

The FAA agrees that Model 757–200 

series airplanes modified under VT 

MAE STC ST04242AT should be subject 

to the same inspections as those 

required for Model 757–200 PF series 

airplanes (Group 4 in the service 

information), due to the similar design. 

The FAA has added paragraph (g)(2) of 

this proposed AD to require these 

additional inspections. The FAA 

disagrees with the request to omit the 

inspection of the passenger doors 

because the commenter did not submit 

sufficient data to substantiate an 

acceptable level of safety. 

VT MAE also requested the FAA 

change the proposed compliance time to 

start after the airplane is converted from 

passenger to cargo configuration for the 

inspection at the door cutout lower 

corners of the crew entry door and the 

door cutout lower corners of main deck 

cargo door. The commenter stated that 

the cutout structures are newly installed 

during the freighter conversion. 

The FAA disagrees with the request to 

revise the compliance time because the 

commenter did not submit sufficient 

data to substantiate an acceptable level 

of safety. However, the FAA will 

consider requests for approval of 

AMOCs and compliance times if 

sufficient data is submitted to 

substantiate the changes would provide 

an acceptable level of safety. 

Request To Add Inspections and 

Change Compliance Time for Airplanes 

Modified per VT MAE STC ST03562AT 

or ST03952AT 

FedEx and VT MAE requested the 

FAA add inspections for airplanes 

modified from a passenger configuration 

to a cargo configuration. VT MAE stated 

that under STCs ST03562AT and 

ST03952AT, the main deck cargo door 

surround cutout structure is similar in 

design to Boeing Model 757–200 

airplanes in a special freighter 

configuration under STC ST00916WI–D 

(identified as Group 6 in Boeing Alert 

Requirements Bulletin 757–53A0119 

RB, dated October 12, 2022). Thus, VT 

MAE requested that airplanes modified 

under STC ST03562AT or ST03952AT 

be inspected as specified in Boeing 

Alert Requirements Bulletin 757– 

53A0119 RB, dated October 12, 2022, 

including the inspection at the door 

cutout lower corners of the main deck 

cargo door specified for Group 6 in 

Table 5. FedEx made the same request 

regarding airplanes modified under STC 

ST03562AT. 

The FAA agrees that Model 757–200 

airplanes modified under VT MAE STC 

ST03562AT or ST03952AT should be 

subject to the same inspections as those 

required for Model 757–200 airplanes 

modified under STC ST00916WI–D 

(Group 6 in the service information), 

due to the similar design. The FAA has 

added paragraph (g)(3) of this proposed 

AD to require these additional 

inspections. 

VT MAE and FedEx also requested 

the FAA change the proposed 

compliance time to start after the 

airplane is converted from passenger to 

cargo configuration for the inspection at 

the door cutout lower corners of main 

deck cargo door. The commenters stated 

that the cutout structure surrounding 

the main deck cargo doors are added 

during passenger-to-cargo conversion, 

rather than when the airplanes are 

manufactured. 

The FAA disagrees with the request to 

revise the compliance time because the 

commenters did not submit sufficient 

data to substantiate an acceptable level 

of safety. However, the FAA will 

consider requests for approval of 

alternative compliance times as an 

AMOC if sufficient data is submitted to 

substantiate the change would provide 

an acceptable level of safety.

Request To Clarify Exceptions 

Paragraph 

FedEx requested the FAA clarify 

paragraph (h)(2) of the proposed AD and 

provided suggested language. 

The FAA determined that the 

language provided by the commenter is 

identical to the language in paragraph 

(h)(2) of the proposed AD. However, the 

FAA has revised the language in 

paragraph (h)(2) of this proposed AD to 

clarify which conditions the exception 

applies to. 

FAA’s Determination 

The FAA is issuing this SNPRM after 

determining 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, it is necessary to reopen the 

comment period to provide additional 

opportunity for the public to comment 

on this SNPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 757–53A0119 

RB, dated October 12, 2022. This service 

information specifies procedures for 

either a general visual inspection or a 

maintenance records check for repairs 

in the areas around the fuselage skin 

door cutout lower corners of the No. 1, 

No. 2, and No. 4 passenger entry doors; 

crew entry door; No. 1, No. 2, and No. 

3 cargo doors; and main deck cargo 

door; and applicable on-condition 

actions, including repetitive low 

frequency and high frequency eddy 

current inspections for cracks in the 

skin or bear strap in the unrepaired 

areas, and crack repair. 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 ADDRESSES. 

Proposed AD Requirements in This 

SNPRM 

This proposed AD would require 

accomplishing the actions specified in 

the service information 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 this service 

information at regulations.gov by 

searching for and locating Docket No. 

FAA–2023–0017. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 482 

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 

General visual inspection for repairs .............. 1 work-hour × $85 per hour = $85 ................. $0 $85 $40,970 

The FAA estimates the following 

costs to do any necessary on-condition 

actions that would be required based on 

the results of the proposed inspection. 

The agency has no way of determining 

the number of airplanes that might need 

these on-condition actions: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

Inspections for cracks .............................. Up to 27 work-hours × $85 per hour = 

Up to $2,295 per inspection cycle.

$0 Up to $2,295 per inspection cycle. 

The extent of cracking found during 

the on-condition inspection could vary 

significantly from airplane to airplane. 

The FAA has no way of determining the 

extent of cracking that may be found on 

each airplane, the cost to repair the 

cracking on each airplane, or the 

number of airplanes that may require 

repair. 

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

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

The Boeing Company: Docket No. FAA– 

2023–0017; Project Identifier AD–2022– 

01418–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by October 23, 

2023. 

(b) Affected ADs 

None. 

(c) Applicability 

(1) This AD applies to all The Boeing 

Company Model 757–200, –200PF, –200CB, 

and –300 series airplanes, certificated in any 

category. 

(2) Installation of Supplemental Type 

Certificate (STC) ST01518SE does not affect 

the ability to accomplish the actions required 

by this AD. Therefore, for airplanes on which 

STC ST01518SE is installed, a ‘‘change in 

product’’ alternative method of compliance 

(AMOC) approval request is not necessary to 

comply with the requirements of 14 CFR 

39.17. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 53, Fuselage. 

(e) Unsafe Condition 

This AD was prompted by the potential for 

cracks to start in hidden areas underneath the 

scuff plates in the fuselage skin and bear 

strap of certain doors. The FAA is issuing 

this AD to address cracks caused by higher 

fatigue stresses at the fuselage skin door 

cutout lower corners. This unsafe condition, 

if not addressed, could adversely affect the 

structural integrity of the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) For all airplanes: Except as specified by 

paragraph (h) of this AD, at the applicable 

times specified in the ‘‘Compliance’’
