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 Joseph Hodgin, 

Aviation Safety Engineer, FAA, 2200 

South 216th St., Des Moines, WA 98198; 

phone: 206–231–3962; email: 

Joseph.J.Hodgin@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 reports from 

operators of cracks found on the forward 

entry door and forward service door 

cutout aft lower corner fuselage skin 

and bear strap between stringer 19 and 

the lower main sill chord, from station 

(STA) 332 to STA 340. The cracks were 

reported between 25,983 and 47,385 

total flight cycles, and between 45,771 

and 80,680 total flight hours. These 

cracks have been occurring at earlier 

flight cycles and are spreading faster 

than initially predicted. One Model 

767–300 operator reported a 5.3-inch 

crack on the forward service door, 

common to only the skin in the lower 

aft corner, and an associated 0.32-inch 

crack in the bear strap at the same 

location. The airplane had completed 

43,459 total flight cycles and 61,086 

total flight hours when the cracks were 

discovered. Undetected fatigue cracks, if 

not addressed, could result in a 

principal structural element’s loss of 

limit load capability, adversely affecting 

the airplane’s structural integrity. 

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. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 767–53A0301 

RB, Revision 2, dated May 24, 2023. 

This service information specifies 

procedures for repetitive inspections 

(external detailed, internal detailed, and 

open hole high frequency eddy current) 

for cracking at the forward entry door 

and forward service door cutout aft 

lower corner fuselage skin and bear 

strap area. This service information also 

specifies procedures for on-condition 

actions, including 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 

NPRM 

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. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 682 

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 

Inspections ............................. Up to 8 work-hours × $85 per 

hour = $680 per inspection 

cycle.

$0 Up to $680 per inspection 

cycle.

Up to $463,760 per inspection 

cycle. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition actions (i.e., 

possible crack repair) 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, 


ddrumheller on DSK120RN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 192 / Thursday, October 5, 2023 / Proposed Rules 69109 

(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.

accumulated cycles, or 24 months after the 

effective date of this AD, whichever occurs 

first. 

(j) Compliance Time Definitions 

The definitions in paragraphs (j)(1) through 

(5) of this AD apply to this AD. 

(1) A ‘‘flight cycle’’ is an operation by an 

aircraft that is initially stopped on the 

ground, departs in flight, attains a maximum 

above ground level (AGL) altitude greater 

than 5,000 feet relative to the runway, lands 

on a runway, and stops on the ground. A 

flight cycle may include one or more touchand-go cycles. 

(2) A ‘‘touch-and-go cycle’’ is an operation 

by an aircraft that lands and departs on a 

runway without stopping or exiting the 

runway and is immediately followed by a 

short flight with a maximum AGL altitude of 

5,000 feet relative to the runway. 

(3) ‘‘Total accumulated cycles’’ is the sum 

of the accumulated number of flight cycles, 

accumulated missed approaches, and the 

accumulated number of touch-and-go cycles. 

(4) A ‘‘missed approach’’ (or go-around) is 

an aircraft landing approach that is 

discontinued and proceeded by a climb-out 

for any reason without landing gear touching 

the runway and is either immediately 

preceded by or immediately followed by a 

short flight with a maximum AGL altitude of 

5,000 feet relative to the runway. Any flight 

operation not meeting this definition is 

considered a flight cycle. 

(5) ‘‘Cumulative’’ cycles are total cycles 

since new. 

(k) Credit for Previous Actions 

This paragraph provides credit for the 

actions specified in paragraph (g) of this AD, 

if those actions were performed before the 

effective date of this AD using Boeing Alert

Airworthiness Directives; Airbus SAS

certain Airbus SAS Model A320–214, 

A320–216, A320–251N, A320–271N, 

and A321–253NX airplanes. This 

proposed AD was prompted by a quality 

review of the forward cargo door frameto-fuselage skin panel assembly 

identified several fastener holes that 

deviated from the manufacturing
