§ 875.410 May I continue my coverage 

when I leave Federal or military service? 

If you are an active workforce 

member, your coverage will 

automatically continue when you leave 

active service, as long as the Carrier 

continues to receive the required 

premium when due. 

■ 21. Revise § 875.413 to read as 

follows: 

§ 875.413 Is it possible to have coverage 

reinstated? 

(a) Under certain circumstances, your 

coverage can be reinstated. The Carrier 

will reinstate your coverage if it receives 

proof satisfactory to it, within 6 months 

from the date of the written notice of 

termination, that you suffered from a 

cognitive impairment or loss of 

functional capacity, before the grace 

period ended, that caused you to miss 

making premium payments. In that 

event, you will not be required to 

submit to underwriting. Your coverage 

will be reinstated retroactively to the 

termination date but you must pay back 

premiums for that period. The premium 

will be the same as it was prior to 

termination. 

(b) If your coverage has terminated 

because you did not pay premiums or 

because you requested cancellation, the 

Carrier may reinstate your coverage 

within 12 months from the date of the 

written notice of termination at your 

request. You will be required to reapply 

based on full underwriting, and the 

Carrier will determine whether you are 

still insurable. If you are insurable, your 

coverage will be reinstated retroactively 

to the termination date and you must 

pay back premiums for that period. The 

premium will be the same as it was 

prior to termination.

Airworthiness Directives; General 

Electric Company Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain General Electric Company (GE) 

GEnx-1B model turbofan engines. This 

proposed AD was prompted by several 

reports of fuel leaks caused by high 

cycle fatigue (HCF) cracks found at the 

braze joints on fuel manifolds, and the 

subsequent manufacturer redesign of the 

high-pressure turbine (HPT) fuel hose 

variable stator vane (VSV) manifold, 

VSV fuel hose manifold, low-pressure 

turbine (LPT) fuel hose variable bleed 

valve (VBV) manifold, and VBV fuel 

hose manifold. This proposed AD 

would require removal and replacement 

of the fuel hydraulic lines. The FAA is 

proposing this AD to address the unsafe 

condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by July 18, 2022. 

ADDRESSES: You may send comments,

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 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. 

Background 

The FAA received reports of fuel 

manifold leaks resulting in multiple 

flight delays and cancellations on four 

separate occasions between 2018 and 

2021 on airplanes with GEnx-1B model 

turbofan engines installed. The 

manufacturer’s investigation revealed 

that variations in braze coverage and 

braze fillet radii caused high stress 

concentration factors at the braze block 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 87, No. 107 / Friday, June 3, 2022 / Proposed Rules 33659 

joints, leading to HCF failure in the tube 

bundles with brazed joints. As a result 

of its investigation, the manufacturer 

determined that the HPT fuel hose VSV 

manifold, VSV fuel hose manifold, LPT 

fuel hose VBV manifold, and VBV fuel 

hose manifold required redesign by 

replacing all braze features and 

cushioned clamps with block clamps. 

The manufacturer published GE GEnx1B Service Bulletin 73–0099 R00, dated 

February 28, 2022, which specifies 

procedures for the replacement of fuel 

hydraulic lines with redesigned fuel 

hydraulic lines. This condition, if not 

addressed, could result in engine fire 

and damage to the airplane. 

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 GE GEnx-1B 

Service Bulletin 73–0099 R00, dated 

February 28, 2022. This service 

information specifies procedures for the 

removal and replacement of the fuel 

hydraulic lines. 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 the 

removal and replacement of the fuel 

hydraulic lines. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 298 

engines installed on 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 

Remove fuel hydraulic lines ............................ 2 work-hours × $85 per hour = $170 ............. $0 $170 $50,660 

Install redesigned fuel hydraulic lines ............. 2.5 work-hours × $85 per hour = $212.50 ..... 232,000 232,212.50 69,199,325 

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.
