SUPPLEMENTARY INFORMATION: 

Background 

On July 20, 2021, a Boeing model 

747–8F airplane, powered by GEnx– 

2B67/P model turbofan engines, flying 

from Hong Kong to Dubai, experienced 

N1 overspeed and fire warnings that 

resulted in an IFSD and air turnback 

(ATB) to Hong Kong. After landing, the 

engine reignited and emergency crews 

extinguished the fire. The investigation 

led by the National Transportation 

Safety Board found several fuel system 

leaks including at the FMU supply 

pressure (P1) BPV pressure port with a 

loose FMU BPV plug safety cabled in 

place. Because a safety cable was in 

place, the investigation concluded that 

the FMU BPV plug might not have been 

torqued properly during production or 

during an engine shop visit. During the 

investigation, GE discovered that 

another operator, operating a Boeing 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 87, No. 35 / Tuesday, February 22, 2022 / Rules and Regulations 9433 

model 787–10 airplane, powered by 

GEnx–1B74/75/P2 model turbofan 

engines, found a fuel system leak related 

to a loose FMU BPV plug in August 

2020 during a walk-around after a flight. 

As a result of the investigation, the 

manufacturer published GE GEnx–1B 

Service Bulletin (SB) 73–0100 R00, 

dated December 3, 2021, and GE GEnx– 

2B SB 73–0092 R00, dated December 3, 

2021, specifying procedures to inspect 

the FMU BPV plug and, depending on 

the results of the inspection, 

replacement of the FMU. This 

condition, if not addressed, could result 

in loss of engine thrust control, IFSD, 

and reduced control of the aircraft. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

FAA’s Determination 

The FAA is issuing this AD because 

the agency has determined the unsafe 

condition described previously is likely 

to exist or develop in other products of 

the same type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed GE GEnx–1B SB 

73–0100 R00, dated December 3, 2021, 

and GE GEnx–2B SB 73–0092 R00, 

dated December 3, 2021. These SBs 

specify procedures for inspecting the 

FMU BPV plug and replacing the FMU 

on GE GEnx–1B and GEnx–2B model 

turbofan engines. 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. 

AD Requirements 

This AD requires a shim check 

inspection of the FMU BPV plug and, 

depending on the results of the 

inspection, replacement of the FMU. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause,’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies foregoing notice 

and comment prior to adoption of this 

rule. On July 20, 2021, a Boeing model 

747–8F airplane, powered by GEnx– 

2B67/P model turbofan engines, 

experienced an IFSD and ATB due to a 

fuel system leak. This unsafe condition, 

caused by improper torquing of the 

FMU BPV plug, may result in the loss 

of engine thrust control, IFSD, and 

reduced control of the aircraft. 

The FAA considers inspection of the 

FMU BPV plug to be an urgent safety 

issue. Inspection of the FMU BPV plug 

must be accomplished within 150 flight 

cycles after the effective date of this AD. 

The FAA estimates that engines affected 

by this AD will accumulate 150 flight 

cycles within approximately 90 days of 

the effective date of this AD. These 

conditions still exist, therefore, notice 

and opportunity for prior public 

comment are impracticable and contrary 

to the public interest pursuant to 5 

U.S.C. 553(b)(3)(B). 

In addition, the FAA finds that good 

cause exists pursuant to 5 U.S.C. 553(d) 

for making this amendment effective in 

less than 30 days, for the same reasons 

the FAA found good cause to forego 

notice and comment. 

Comments Invited 

The FAA invites you to send any 

written data, views, or arguments about 

this final rule. Send your comments to 

an address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2022–0101 

and Project Identifier AD–2021–01456– 

E’’ at the beginning of your comments. 

The most helpful comments reference a 

specific portion of the final rule, 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 final rule 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 https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this final rule. 

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 AD 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 AD, 

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 AD. Submissions containing CBI 

should be sent to Alexei Marqueen, 

Aviation Safety Engineer, ECO Branch, 

FAA, 1200 District Avenue, Burlington, 

MA 01803. Any commentary that the 

FAA receives which is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Regulatory Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because FAA 

has determined that it has good cause to 

adopt this rule without prior notice and 

comment, RFA analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 114 engines installed on 

airplanes of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Shim check inspection of FMU BPV plug ...... 0.50 work-hours × $85 per hour = $42.50 ..... $0 $42.50 $4,845 


lotter on DSK11XQN23PROD with RULES1
9434 Federal Register / Vol. 87, No. 35 / Tuesday, February 22, 2022 / Rules and Regulations 

The FAA estimates the following 

costs to do any necessary replacement 

that would be required based on the 

results of the inspection. The agency has 

no way of determining the number of 

aircraft that might need this 

replacement: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replace the FMU with a FMU that has undergone 

packing replacement.

8 work-hours × $85 per hour = $680 ........................... $200 $880 

Replace the FMU ......................................................... 7 work-hours × $85 per hour = $595 ........................... 727,317 727,912 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Continental Aerospace Technologies, 

Inc. C–125, C145, IO–360, IO–470, IO– 

550, O–300, O–470, TSIO–360, TSIO– 

520 series model reciprocating engines 

and certain Continental Motors IO–520 

series model reciprocating engines with 

a certain oil filter adapter installed. This 

AD was prompted by reports of two 

accidents that were the result of power 

loss due to oil starvation. This AD 

requires replacing the oil filter adapter 

fiber gasket (fiber gasket) with an oil 

filter adapter copper gasket (copper 

gasket). The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective March 29, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 29, 2022.

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 certain Continental Aerospace 

Technologies, Inc. (Type Certificate 

previously held by Continental Motors, 

Inc., and Teledyne Continental Motors) 

C–125–1, C–125–2, C145–2, C145–2H, 

IO–360–C, IO–360–D, IO–360–DB, IO– 

360–H, IO–360–HB, IO–360–K, IO–360– 

KB, IO–470–E, IO–470–S, IO–550–B, 

IO–550–G, O–300–B, O–300–C, O–300– 

D, O–300–E, O–470–A, O–470–B, O– 

470–G, O–470–J, O–470–K, O–470–L, 

O–470–M, O–470–N, O–470–R, O–470– 

S, O–470–U, O–470–11, O–470–15, 

TSIO–360–E, TSIO–360–EB, TSIO–360– 

F, TSIO–360–FB, TSIO–360–GB, TSIO– 

360–LB, TSIO–360–MB, TSIO–360–SB, 

TSIO–520–C, TSIO–520–CE, TSIO–520– 

E, TSIO–520–UB model reciprocating 

engines; and Continental Motors (Type 

Certificate previously held by Teledyne 

Continental Motors) IO–520–A, IO–520– 

B, IO–520–BA, IO–520–BB, IO–520–C, 

IO–520–D, IO–520–J, and IO–520–L 

model reciprocating engines. The NPRM 

published in the Federal Register on 

October 12, 2021 (86 FR 56658). The 

NPRM was prompted by reports of two 

accidents that were the result of power 

loss due to oil starvation. The first was 

a fatal accident on May 1, 2019, in Mill 

Creek California, involving a Cessna 

182P airplane with an installed 

Continental Motors O–470–S engine. 

The National Transportation Safety 

Board’s preliminary accident 

investigation report, docket number 

WPR19FA126, identified evidence of 

improperly maintained or installed oil 

filter adapters. An improperly 

maintained or installed oil filter adapter 

may lead to failure of the fiber gasket, 

which may result in oil loss or oil 

starvation. Based on the investigation, 

the manufacturer determined the need 

to replace the fiber gasket with a copper 

gasket. In the NPRM, the FAA proposed 

to require removal of the fiber gasket 

and replacement with a copper gasket.
