(e) Unsafe Condition 

This AD was prompted by investigation by 

the manufacturer that revealed Teflon 

material in the A-sump oil strainer (strainer 

assembly) screen after several reports of inflight shutdowns and unscheduled engine 

removals. The FAA is issuing this AD to 

prevent failure of the stationary oil seal at the 

No.1 forward bearing. The unsafe condition, 

if not addressed, could result in failure of the 

engine, in-flight shutdown, and loss of 

control of the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) Within the compliance time specified 

in paragraph (g)(1)(i) or (ii) of this AD, as 

applicable, perform an initial visual 

inspection of the strainer assembly screen for 

Teflon material. Guidance on performing the 

visual inspections of the strainer assembly 

screen can be found in the Accomplishment 

Instructions, paragraphs 3.A.(1)(d), of GE 

CF34–10E Service Bulletin (SB) 72–0365 

R04, dated April 27, 2021. 

(i) For an affected stationary oil seal having 

fewer than 2,250 flight hours (FHs) since new 

on the effective date of this AD, perform the 

initial inspection of the strainer assembly 

screen at the next engine shop visit after 

accumulating 2,250 FHs since new, but no 

later than 2,350 FHs since new. 

(ii) For an affected stationary oil seal 

having 2,250 or more FHs since new on the 

effective date of this AD, perform the initial 

inspection of the strainer assembly screen 

within 100 FHs after the effective date of this 

AD. 

(2) Thereafter, within the following 

compliance times, repeat the visual 

inspection of the strainer assembly screen 

required by paragraph (g)(1) of this AD: 

(i) For an affected stationary oil seal having 

2,250 to 7,000 FHs since new at the time of 

the last inspection, repeat the visual 

inspection every 750 FHs. 

(ii) For an affected stationary oil seal 

having 7,001 to 10,000 FHs since new at the 

time of the last inspection, repeat the visual 

inspection every 375 FHs. 

(iii) For an affected stationary oil seal 

having more than 10,000 FHs since new at 

the time of the last inspection, repeat the 

visual inspection every 100 FHs. 

(3) If, based on the inspections required by 

paragraph (g)(1) or (2) of this AD, Teflon 

material is found in the strainer assembly 

screen, before further flight, remove the 

stationary oil seal at the No. 1 forward 

bearing from service and replace it with a 

part eligible for installation. 

(4) Before an affected stationary oil seal 

accumulates 10,000 FHs since new or within 

500 FHs after the effective date of this AD, 

whichever occurs later, remove the stationary 

oil seal at the No. 1 forward bearing from 

service and replace it with a part eligible for 

installation. 

(h) Terminating Action 

Removal of the stationary oil seal, P/N 

B1316–00453 or P/N B1316–01274, installed 

at the No. 1 forward bearing, and 

replacement with a part eligible for 

installation, constitutes terminating action 

for the initial and repetitive inspections 

required by paragraphs (g)(1) and (2) of this 

AD. 

(i) Definition 

For the purpose of this AD, a ‘‘part eligible 

for installation’’ is a stationary oil seal that 

has a P/N other than P/N B1316–00453 or P/ 

N B1316–01274. 

(j) Special Flight Permit 

Special flight permits, as described in 14 

CFR 21.197 and 21.199, are subject to the 

requirements of paragraph (j)(1) of this AD. 

(1) Operators who are prohibited from 

further flight due to Teflon material found in 

the strainer assembly screen may perform a 

non-revenue ferry flight, consisting of no 

more than five cycles, to a location where the 

engine can be removed from service if 

operators perform the actions in Appendix— 

A, paragraph 4.A., GE CF34–10E Service 

Bulletin (SB) 72–0365 R04, dated April 27, 

2021 and the engine still meets the criteria 

in paragraph 4.A. for flying an additional five 

cycles. This ferry flight must be performed 

with only essential flight crew, without 

passengers, and involve non-ETOPS 

operations.

RIN 2120–AJ38 

Safety Management System for 

Certificated Airports 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (SNPRM); 

reopening of comment period. 

SUMMARY: This action reopens the 

comment period for the Safety 

Management System for Certificated 

Airports SNPRM published July 14, 

2016. In the SNPRM, the FAA proposed 

to amend certain requirements included 

in the notice of proposed rulemaking 

published on October 7, 2010. Most 

notably, the FAA revised the proposed 

applicability of the rule so that a Safety 

Management System (SMS) is only 

required for a certificated airport 

classified as a small, medium, or large 

hub airport in the National Plan of 

Integrated Airport Systems; serving 

international air traffic; or having more 

than 100,000 total annual operations. 

The FAA also proposed changes that 

would extend the implementation 

period from 18 to 24 months; require 

submission of an implementation plan 

within 12 months instead of 6 months 

of the effective date of the final rule; 

modify the training requirements;

SMS initiatives, and reduce the 

implementation burden. 

DATES: The comment period for the 

SNPRM published on July 14, 2016 (81 

FR 45872) closed on September 12, 

2016, and is reopened until September

SUPPLEMENTARY INFORMATION: See the 

‘‘Additional Information’’ section for 

information on how to comment on this 

proposal and how the FAA will handle 

comments received. The ‘‘Additional 

Information’’ section also contains 

related information about the docket, 

privacy, the handling of proprietary or 

confidential business information. In 

addition, there is information on 

obtaining copies of related rulemaking 

documents. 

Background 

On October 7, 2010, the FAA 

published in the Federal Register a 

notice of proposed rulemaking (NPRM) 

titled ‘‘Safety Management System for 

Certificated Airports’’ (75 FR 62008). 

The NPRM proposed to require all part 

139 certificate holders to establish a 

Safety Management System (SMS) for 

the entire airfield environment, 

including movement and nonmovement areas, to improve safety at 

airports hosting air carrier operations. 

While reviewing the comments on the 

NPRM, the FAA reevaluated whether 

requiring an SMS at all part 139 

certificated airports was appropriate. As 

part of the re-evaluation, the FAA 

assessed various combinations of 

criteria that could trigger the 

requirement to implement SMS and to 

maximize safety benefits in the least 

burdensome manner. 

On July 14, 2016, the FAA published 

an SNPRM titled ‘‘Safety Management 

System for Certificated Airports’’ (81 FR 

45872). The SNPRM revised the 

proposed triggers for implementing SMS 

and proposed the FAA’s preferred 

alternative, which is to require SMS at 

airports that (a) are large, medium, or 

small hubs; (b) serve international air 

traffic; or (c) have more than 100,000 

total annual operations. The FAA also 

revised the proposed implementation 

schedule to extend the implementation 

period from 18 months to 24 months 

and require the submission of an 

Implementation Plan within 12 months 

(instead of 6 months) from the effective 

date of the rule. The SNPRM clarified 

the training requirements and revised 

certain definitions to ensure 

consistency—when deemed 

appropriate—among various FAA SMS 

initiatives. 

The SNPRM comment period closed 

on September 12, 2016. The FAA 

received 38 comments on the SNPRM. 

Although most commenters were 

certificate holders, some were air 

carriers, consultants, academia, and 

individuals. Additionally, the following 

industry associations submitted 

comments: Airlines for America, 

Airports Council International-North 

America, American Association of 

Airport Executives, Helicopter 

Association International, and the 

National Business Aviation Association. 

The comments primarily addressed the 

following areas of the proposal: 

• Applicability; 

• Implementation; 

• Non-movement area; 

• Data protection; 

• Safety reporting and 

interoperability; 

• Training and orientation; 

• Accountable executive; 

• Definitions; and 

• Miscellaneous topics. 

Reopening of Comment Period 

As a result of the time that has passed 

since the close of the SNPRM comment 

period, the FAA has determined that it 

is appropriate to solicit comments on 

any new information or data that has 

come to light since the close of the 

comment period. Accordingly, the FAA 

is reopening the comment period for the 

SNPRM published at 81 FR 45872, for 

30 days, until September 23, 2021 for 

the aforementioned limited purpose. 

The most helpful comments provide 

only data and information that was not 

previously submitted to the rulemaking 

docket, reference a specific portion of 

the proposal, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should send only one copy 

of written comments, or if comments are 

filed electronically, commenters should 

submit only one time. 

Additional Information 

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 file in the docket all 

comments it receives, as well as a report 

summarizing each substantive public 

contact with FAA personnel concerning 

this proposed rulemaking. Before acting 

on this proposal, the FAA will consider 

all comments it receives on or before the 

closing date for comments. The FAA 

will consider comments filed after the 

comment period has closed if it is 

possible to do so without incurring 

expense or delay. The agency may 

change this proposal in light of the 

comments it receives. 

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 SNPRM
