Category 2 issues—Environmental issues for which a generic finding regarding the environmental impacts cannot be reached because the issue requires the consideration of project-specific information that can only be evaluated once the proposed site is identified. The impact significance (i.e., SMALL, MODERATE, or 

LARGE) for these issues will be determined in a project-specific evaluation. 

N/A—Issues related to exposure to electromagnetic fields (EMFs) for which there is no national scientific agreement regarding adverse health effects. 

3A finding of SMALL impacts means that environmental effects are not detectable or are so minor that they will neither destabilize nor noticeably alter any important attribute of the resource. For the purposes of assessing radiological impacts, the Commission has concluded that those impacts that do not exceed permissible 

levels in the Commission’s regulations are considered SMALL as the term is used in this table. For issues where probability is a key consideration (i.e., accident consequences), probability was a factor in determining significance. 4Because the Category 2 issues require a project-specific review, there are no associated values and assumptions of the plant parameter envelope and site parameter envelope. A brief summary explanation for the designation of the Category 2 issues is provided in lieu of values and assumptions.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (SNPRM). 

SUMMARY: The FAA is revising an earlier 

notice of proposed rulemaking (NPRM) 

to supersede Airworthiness Directive 

(AD) 2012–07–06. AD 2012–07–06 

applies to certain The Boeing Company 

Model 777–200, –200LR, –300, –300ER, 

and 777F series airplanes. This action 

revises the NPRM by proposing to 

require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

The FAA is proposing this AD to 

address the unsafe condition on these 

products. Since these actions would 

impose an additional burden over those 

in the NPRM, the FAA is requesting 

comments on this SNPRM. 

DATES: The FAA must receive comments 

on this SNPRM by November 18, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

Background 

The FAA issued AD 2012–07–06, 

Amendment 39–17012 (77 FR 21429, 

April 10, 2012) (AD 2012–07–06), for 

The Boeing Company Model 777–200, 

200LR, –300, –300ER, and 777F series 

airplanes with an original airworthiness 

certificate or original export certificate 

of airworthiness issued before 

September 1, 2010. AD 2012–07–06 

requires revising the maintenance 

program to update inspection 

requirements to detect fatigue cracking 

of principal structural elements (PSEs). 

The FAA issued AD 2012–07–06 to 

ensure that fatigue cracking of various 

PSEs is detected and corrected; such 

fatigue cracking could adversely affect 

the structural integrity of these 

airplanes. 

The FAA issued an NPRM to amend 

14 CFR part 39 by adding an AD to 


khammond on DSKJM1Z7X2PROD with PROPOSALS
80828 Federal Register / Vol. 89, No. 193 / Friday, October 4, 2024 / Proposed Rules 

supersede AD 2012–07–06 that would 

apply to certain The Boeing Company 

Model 777–200, –200LR, –300, –300ER, 

and 777F series airplanes. The NPRM 

was published in the Federal Register 

on May 14, 2024 (89 FR 41908). The 

NPRM was prompted by a new revision 

to the airworthiness limitations (AWLs) 

of the maintenance planning document 

(MPD) and the damage tolerance rating 

(DTR) Check Form Document. In the 

NPRM, the FAA proposed to retain the 

requirements of AD 2012–07–06 and 

revise the existing maintenance or 

inspection program by incorporating the 

information in Subsection B, 

Airworthiness Limitations-Structural 

Inspections and Subsection C, 

Airworthiness Limitations-Structural 

Safe-Life Limits, of Section 9, 

Airworthiness Limitations (AWLs) and 

Certification Maintenance Requirements 

(CMRs), D622W001–9, Revision 

December 2022, of the Boeing 777–200/ 

200LR/300/300ER/777F Maintenance 

Planning Data (MPD) Document; and 

Boeing 777–200/200LR/300/300ER/ 

777F Damage Tolerance Rating (DTR) 

Check Form Document, D622W001– 

DTR, dated December 2022. 

Actions Since the NPRM Was Issued 

Since the FAA issued the NPRM, 

Boeing published Section 9, 

Airworthiness Limitations (AWLs) and 

Certification Maintenance Requirements 

(CMRs), D622W001–9, Revision April 

2023, of the Boeing 777–200/200LR/ 

300/300ER/777F Maintenance Planning 

Data (MPD) Document; and Boeing 777– 

200/200LR/300/300ER/777F Damage 

Tolerance Rating (DTR) Check Form 

Document, D622W001–DTR, dated 

April 2023, which contain new and 

more restrictive airworthiness 

limitations (inspections and life limits 

have been updated). The FAA has 

determined it is necessary to mandate 

those airworthiness limitations. 

Airplanes with an original 

airworthiness certificate or original 

export certificate of airworthiness 

issued on or after September 5, 2024, 

must comply with the airworthiness 

limitations specified as part of the 

approved type design and referenced on 

the type certificate data sheet; this 

proposed AD therefore does not include 

those airplanes in the applicability. 

Comments 

The FAA received a comment from 

FedEx Express who supported the 

NPRM without change. 

The FAA received additional 

comments from four commenters, 

including American Airlines (AAL), 

Boeing, Japan Airlines (JAL), and United 

Airlines (UAL). The following presents 

the comments received on the NPRM 

and the FAA’s response to each 

comment. 

Request To Update the Document to the 

Latest Revision 

JAL and UAL requested that the 

proposed AD be revised to change the 

reference to the December 2022 versions 

of the airworthiness limitation 

documents cited in the proposed AD. 

JAL and UAL noted that Section 9, 

Airworthiness Limitations (AWLs) and 

Certification Maintenance Requirements 

(CMRs), D622W001–9, Revision April 

2023, of the Boeing 777–200/200LR/ 

300/300ER/777F Maintenance Planning 

Data (MPD) Document; and Boeing 777– 

200/200LR/300/300ER/777F Damage 

Tolerance Rating (DTR) Check Form 

Document, D622W001–DTR, dated 

April 2023, are already published. UAL 

stated that this change will simplify the 

implementation process for operators by 

removing the need for a new alternative 

method of compliance (AMOC) to 

implement the latest MPD revision. 

UAL stated it has already been working 

toward implementing the April 2023 

revision, even before release of the 

NPRM. 

The FAA agrees with the request. As 

previously stated, the FAA has 

determined it is necessary to mandate 

the new airworthiness limitations 

specified in the Revision April 2023 

AWLs documents because the 

inspections and life limits have been 

updated. The FAA has revised this 

proposed AD accordingly. 

Request To Add a Compliance Time for 

New Parts 

JAL requested that a compliance time 

for new parts, similar to the statement 

in paragraph (g)(2) of AD 2012–07–06, 

be added to this proposed AD, i.e., 

‘‘within the applicable time specified in 

Subsection B, Airworthiness 

Limitations-Structural Inspections, of 

Section 9, ‘Airworthiness Limitations 

(AWLs) and Certification Maintenance 

Requirements (CMRs),’ D622W001–9, 

Revision July 2011, of the Boeing 777 

Maintenance Planning Data (MPD) 

Document, from the time of installation 

for new parts.’’ 

The FAA agrees with the request. The 

compliance time for new parts is still 

applicable as stated previously in AD 

2012–07–06. This compliance time was 

inadvertently excluded from the 

proposed AD (in the NPRM). The FAA 

has revised paragraph (i)(2) of this 

proposed AD (in the SNPRM) 

accordingly. 

Request To Remove a Duplicate 

Reporting Requirement 

The Boeing company requested that 

the FAA removes paragraph (i)(3) of the 

proposed AD. Boeing stated that the 

same reporting requirement is included 

in Section 9, Airworthiness Limitations 

(AWLs) and Certification Maintenance 

Requirements (CMRs), D622W001–9, 

Revision December 2022, of the Boeing 

777–200/200LR/300/300ER/777F 

Maintenance Planning Data (MPD) 

Document. 

The FAA agrees with the request. 

Both the Revision December 2022 and 

Revision April 2023 versions of the 

MPD already include a reporting 

requirement of 10 days after the airplane 

is returned to service. Therefore, the 

exception is not necessary for the 

Revision April 2023 MPD. However, the 

exception is still necessary for the 

Boeing 777–200/200LR/300/300ER/ 

777F Damage Tolerance Rating (DTR) 

Check Form Document, D622W001– 

DTR, dated April 2023. The FAA has 

revised paragraph (i)(3) of the proposed 

AD (in the NPRM) accordingly. 

Request for Clarification of Reporting 

Requirements 

AAL requested that the language in 

the ‘‘Proposed AD Requirements in This 

NPRM’’ paragraph of the NPRM be 

revised from ‘‘This proposed AD would 

also require sending inspection results 

to Boeing’’ to ‘‘This proposed AD would 

also require sending inspection results 

of crack findings to Boeing.’’ AAL also 

requested that paragraph (i)(3) of the 

proposed AD be revised to change 

‘‘Reports specified in Section 9 . . .’’ to 

‘‘Reports of crack findings as specified 

in Section 9 . . . .’’ AAL stated that 

additional clarification is necessary to 

avoid any possible ambiguity in the 

intent of the proposed AD and makes 

the requirement eminently clear that 

only crack findings need to be reported, 

as specified in Section 9, Airworthiness 

Limitations (AWLs) and Certification 

Maintenance Requirements (CMRs), 

D622W001–9, Revision April 2023, of 

the Boeing 777–200/200LR/300/300ER/ 

777F Maintenance Planning Data (MPD) 

Document. 

The FAA partially agrees with the 

requests. The FAA concurs that Section 

9, Airworthiness Limitations (AWLs) 

and Certification Maintenance 

Requirements (CMRs), D622W001–9, 

Revision April 2023, of the Boeing 777– 

200/200LR/300/300ER/777F 

Maintenance Planning Data (MPD) 

Document specifies to report crack 

findings of structural inspections. 

However, as stated previously, 

paragraph (i)(3) of the proposed AD (in 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 89, No. 193 / Friday, October 4, 2024 / Proposed Rules 80829 

the NPRM) has been removed. In 

addition, the ‘‘Proposed AD 

Requirements’’ paragraph in the NPRM 

is not restated in this SNPRM. 

Therefore, the FAA has not revised this 

SNPRM in this regard. 

Request To Extend Compliance Time 

AAL requested that paragraph (i)(2) of 

the proposed AD be revised to ‘‘. . . or 

within 18 months from the AD effective 

date, whichever occurs later,’’ as was 

permitted in paragraph (g)(2) of AD 

2012–07–06. AAL stated that extending 

the compliance time from 12 months to 

18 months will allow operators greater 

flexibility to bridge these requirements 

into their maintenance program without 

the possibility of forcing aircraft out of 

service, especially considering some 

maintenance check intervals may have 

been escalated during the time between 

when AD 2012–07–06 was released, and 

when the proposed AD becomes an AD. 

The FAA does not agree with the 

request. The 12-month compliance time 

(grace period) is being proposed to 

ensure a timely implementation of 

Subsection B, Airworthiness 

Limitations-Structural Inspections and 

Subsection C, Airworthiness 

Limitations-Structural Safe-Life Limits, 

of Section 9, Airworthiness Limitations 

(AWLs) and Certification Maintenance 

Requirements (CMRs), D622W001–9, 

Revision April 2023, of the Boeing 777– 

200/200LR/300/300ER/777F 

Maintenance Planning Data (MPD) 

Document; and Boeing 777–200/200LR/ 

300/300ER/777F Damage Tolerance 

Rating (DTR) Check Form Document, 

D622W001–DTR, dated April 2023, and 

to maintain an adequate level of safety 

in the fleet. Therefore, the FAA has not 

changed this proposed AD regarding 

this request. However, under the 

provisions of paragraph (k) of this 

proposed AD, the FAA will consider 

requests for approval of alternative 

compliance times if sufficient data are 

submitted to substantiate that the 

change would provide an acceptable 

level of safety. 

FAA’s Determination 

The FAA is proposing 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. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

The FAA reviewed Section 9, 

Airworthiness Limitations (AWLs) and 

Certification Maintenance Requirements 

(CMRs), D622W001–9, Revision April 

2023, of the Boeing 777–200/200LR/ 

300/300ER/777F Maintenance Planning 

Data (MPD) Document. Subsection B, 

Airworthiness Limitations—Structural 

Inspections and Subsection C, 

Airworthiness Limitations—Structural 

Safe-Life Limits, of this material 

contains airworthiness limitations for 

structural inspections and structural life 

limits, among other limitations. 

The FAA also reviewed Boeing 777– 

200/200LR/300/300ER/777F Damage 

Tolerance Rating (DTR) Check Form 

Document, D622W001–DTR, dated 

April 2023. This material provides the 

DTR check forms and the procedure for 

their use. 

This proposed AD would also require 

Section 9, ‘‘Airworthiness Limitations 

(AWLs) and Certification Maintenance 

Requirements (CMRs),’’ D622W001–9, 

Revision July 2011, of the Boeing 777 

Maintenance Planning Data (MPD) 

Document, which the Director of the 

Federal Register approved for 

incorporation by reference as of May 15, 

2012 (77 FR 21429, April 10, 2012). 

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 

SNPRM 

For airplanes with an original 

airworthiness certificate or original 

export certificate of airworthiness 

issued before September 1, 2010, this 

proposed AD would retain all the 

requirements of AD 2012–07–06. For 

airplanes with an original airworthiness 

certificate or original export certificate 

of airworthiness issued before 

September 5, 2024, this proposed AD 

would require revising the existing 

maintenance or inspection program to 

incorporate new and more restrictive 

airworthiness limitations, which would 

then terminate the retained 

requirements of AD 2012–07–06. This 

proposed AD would also require 

sending inspection results to Boeing. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 326 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2012–07–06 to be $7,650 (90 workhours × $85 per work-hour). 

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. 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. 

The FAA estimates the total cost per 

operator for the new proposed actions to 

be $7,650 (90 work × hours × $85 per 

work-hour).

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 

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 

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: 

■ a. Removing Airworthiness Directive 

(AD) 2012–07–06, Amendment 39– 

17012 (77 FR 21429, April 10, 2012); 

and 

■ b. Adding the following new AD: 

The Boeing Company: Docket No. FAA– 

2024–1287; Project Identifier AD–2023– 

00992–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by November 

18, 2024. 

(b) Affected ADs 

This AD replaces AD 2012–07–06, 

Amendment 39–17012 (77 FR 21429, April 

10, 2012) (AD 2012–07–06). 

(c) Applicability 

This AD applies to The Boeing Company 

Model 777–200, –200LR, –300, –300ER, and 

777F series airplanes, certificated in any 

category, with an original airworthiness 

certificate or original export certificate of 

airworthiness issued before September 5, 

2024. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 27, Flight Controls; 28, Fuel; 

32, Landing Gear; 52, Doors; 53, Fuselage; 54, 

Nacelles/Pylons; 55, Stabilizers; 57, Wings. 

(e) Unsafe Condition 

This AD was prompted by new revisions 

to the airworthiness limitations of the 

maintenance planning document and damage 

tolerance rating check form document. The 

FAA is issuing this AD to address fatigue 

cracking of various principal structural 

elements. The unsafe condition, if not 

addressed, could result in could adversely 

affect the structural integrity of the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Retained Revision of Maintenance 

Program With No Changes 

This paragraph restates the requirements of 

paragraph (g) of AD 2012–07–06, with no 

changes. For airplanes with an original 

airworthiness certificate or original export 

certificate of airworthiness issued before
