4 blisk) of the mating compressor rotor 

during initial operation. The FAA is issuing 

this AD to prevent uncontained failure of the 

stage 3–4 blisk. The unsafe condition, if not 

addressed, could result in uncontained part 

release, damage to the engine, and damage to 

the aircraft.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all The Boeing Company Model 

767–200, –300, and –300F series 

airplanes. The NPRM published in the 

Federal Register on June 20, 2024 (89 

FR 51856), corrected July 15, 2024 (89 

FR 57377). The NPRM was prompted by 

a report of a MLG collapse event 

following maintenance where a grinder 

was operating outside of its input 

parameters, resulting in possible heat 

damage to the outer cylinder of the 

MLG. In the NPRM, the FAA proposed 

to require replacing any affected outer 

cylinders. The FAA is issuing this AD 

to address any heat damage to the outer 

cylinder of the landing gear, which 

could result in the inability of a 

principal structural element to sustain 

limit load, gear collapse resulting in loss 

of control of the airplane, and potential 

for off-runway excursion. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from Air 

Line Pilots Association, International, 

Aviation Partners Boeing, and an 

individual commenter, who supported 

the NPRM without change. 

The FAA received an additional 

comment from The Boeing Company. 

The following presents the comment 

received on the NPRM and the FAA’s 

response. 

Effect of Winglets on Accomplishment 

of the Proposed Actions 

Aviation Partners Boeing stated that 

accomplishing Supplemental Type 

Certificate (STC) ST01920SE does not 

affect the actions specified in the 

proposed AD. 

The FAA concurs with the 

commenter. The FAA has redesignated 

paragraph (c) of the proposed AD as 

paragraph (c)(1) of this AD and added 

paragraph (c)(2) to this AD to state that 

installation of STC ST01920SE does not 

affect the ability to accomplish the 

actions required by this AD. Therefore, 

for airplanes on which STC ST01920SE 

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 for Parts Installation 

Prohibition Paragraph 

Boeing requested the addition of a 

parts installation prohibition paragraph 

as of the effective date of this AD. 

Boeing stated that the parts prohibition 

paragraph should prohibit installation 

of any affected outer cylinders with part 

numbers and serial numbers listed in 

Appendix A, B, or C of Boeing Alert 

Requirements Bulletin 767–32A0253 

RB, dated February 6, 2024, unless the 

parts have been inspected, applicable 

on-condition corrective actions have 

been done, and the parts have been part 

marked, in accordance with Appendix D 

of Boeing Alert Requirements Bulletin 

767–32A0253 RB. The MLG outer 

cylinders are rotable structural 

components (RSC) that may be moved 

from one airplane to another. 

Additionally, the commenter asserted 

that since the applicability of the 

proposed AD covers all Model 767–200, 

–300, and –300F series airplanes in 

service, the parts installation 

prohibition is needed to prevent the 

affected outer cylinders from being 

moved onto airplanes that have already 

complied with the required actions of 

the AD. 

The FAA agrees to clarify. This AD 

applies to all The Boeing Company 

Model 767–200, –300, and –300F 

airplanes. 14 CFR 39.7 specifies that 

once an AD is issued, no person may 

operate a product to which the AD 

applies except in accordance with the 

requirements of that AD. Further, 14 

CFR 39.9 imposes a continuing 

obligation to maintain compliance with 

an AD by establishing a separate 

violation for each time an aircraft is 

operated that fails to meet AD 

requirements. Since this AD captures all 

possibly affected operators and requires 

replacement of the affected parts, and 

since those operators have an ongoing 

obligation to ensure that the ADmandated configuration is maintained, a 

parts installation prohibition is 

unnecessary. The FAA has not changed 

this AD as a result of the request. 

Conclusion 

The FAA reviewed the relevant data, 

considered any comments received, and 

determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. Except for minor editorial 

changes, this AD is adopted as proposed 

in the NPRM. None of the changes will 

increase the economic burden on any 

operator. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 767–32A0253 

RB, dated February 6, 2024. This 

material specifies procedures for 

performing a check of maintenance 

records or performing an inspection of 

the left and right MLG outer cylinders 

for any affected part numbers and serial 

numbers and replacing affected 

cylinders. 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 574 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection or maintenance records check 

for affected part numbers.

Up to 3 work-hours × $85 per hour = $255 $0 Up to $255 .......... Up to $146,370. 

The FAA estimates the following 

costs to do any necessary replacements 

that would be required based on the 

results of the inspection or maintenance 

records check. The agency has no way 

of determining the number of aircraft 

that might need this replacement: 


lotter on DSK11XQN23PROD with RULES1
1370 Federal Register / Vol. 90, No. 5 / Wednesday, January 8, 2025 / Rules and Regulations 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per product 

Replacement of MLG outer cylinder (83 affected 

parts).

189 work-hours * × $85 per hour = $16,065 ............ * $500,000 $516,065 

* Task work-hours and parts cost are based on one MLG outer cylinder replacement. 

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

(1) This AD applies to all The Boeing 

Company Model 767–200, –300, and –300F 

series airplanes, certificated in any category. 

(2) Installation of Supplemental Type 

Certificate (STC) ST01920SE does not affect 

the ability to accomplish the actions required 

by this AD. Therefore, for airplanes on which 

STC ST01920SE 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 32, Landing Gear. 

(e) Unsafe Condition 

This AD was prompted by a report of a 

main landing gear (MLG) collapse event 

following maintenance where a grinder was 

operating outside of its input parameters, 

resulting in possible heat damage to the outer 

cylinder of the MLG. The FAA is issuing this 

AD to address any heat damage to the outer 

cylinder of the landing gear. The unsafe 

condition, if not addressed, could result in 

the inability of a principal structural element 

to sustain limit load, gear collapse resulting 

in loss of control of the airplane, and 

potential for off-runway excursion. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Except as specified by paragraph (h) of this 

AD: At the applicable times specified in the

SUPPLEMENTARY INFORMATION: This rule 

amends 14 CFR part 97 by establishing, 

amending, suspending, or removes 

SIAPS, Takeoff Minimums and/or 

ODPS. The complete regulatory 

description of each SIAP and its 

associated Takeoff Minimums or ODP 

for an identified airport is listed on FAA 

form documents which are incorporated 

by reference in this amendment under 5 

U.S.C. 552(a), 1 CFR part 51, and 14 

CFR 97.20. The applicable FAA Forms 

are 8260–3, 8260–4, 8260–5, 8260–15A, 

8260–15B, when required by an entry 

on 8260–15A, and 8260–15C. 

The large number of SIAPs, Takeoff 

Minimums and ODPs, their complex 

nature, and the need for a special format 

make publication in the Federal 

Register expensive and impractical. 

Further, pilots do not use the regulatory 

text of the SIAPs, Takeoff Minimums or 

ODPs, but instead refer to their graphic 

depiction on charts printed by 

publishers of aeronautical materials. 

Thus, the advantages of incorporation 

by reference are realized and 

publication of the complete description 

of each SIAP, Takeoff Minimums and 

ODP listed on FAA form documents is 

unnecessary. This amendment provides 

the affected CFR sections and specifies 

the types of SIAPS, Takeoff Minimums 

and ODPs with their applicable effective 

dates. This amendment also identifies 

the airport and its location, the 

procedure, and the amendment number. 

Availability and Summary of Material 

Incorporated by Reference 

The material incorporated by 

reference is publicly available as listed 

in the ADDRESSES section. 

The material incorporated by 

reference describes SIAPS, Takeoff 

Minimums and/or ODPs as identified in 

the amendatory language for part 97 of 

this final rule. 

The Rule 

This amendment to 14 CFR part 97 is 

effective upon publication of each 

separate SIAP, Takeoff Minimums and 

ODP as amended in the transmittal. 

Some SIAP and Takeoff Minimums and 

textual ODP amendments may have 

been issued previously by the FAA in a 

Flight Data Center (FDC) Notice to Air 

Missions (NOTAM) as an emergency 

action of immediate flights safety 

relating directly to published 

aeronautical charts. 

The circumstances that created the 

need for some SIAP and Takeoff 

Minimums and ODP amendments may 

require making them effective in less 

than 30 days. For the remaining SIAPs 

and Takeoff Minimums and ODPs, an 

effective date at least 30 days after 

publication is provided. 

Further, the SIAPs and Takeoff 

Minimums and ODPs contained in this 

amendment are based on the criteria 

contained in the U.S. Standard for 

Terminal Instrument Procedures
