Airworthiness Directives; General 

Electric Company Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

General Electric Company (GE) Passport 

20–17BB1A, Passport 20–18BB1A, and 

Passport 20–19BB1A model turbofan 

engines. This AD was prompted by a 

report of a manufacturing quality escape 

that requires a reduction to the life limit 

of certain high-pressure turbine (HPT) 

rotor stage 1 disks. This AD requires 

revising the airworthiness limitations 

section (ALS) of the existing 

maintenance manual and the operator’s 

existing approved continuous 

airworthiness maintenance program 

(CAMP) to incorporate a reduced life 

limit for certain HPT rotor stage 1 disks. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD is effective March 21, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 21, 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 all GE Passport 20–17BB1A, 

Passport 20–18BB1A, and Passport 20– 

19BB1A model turbofan engines. The 

NPRM published in the Federal 

Register on November 29, 2021 (86 FR 

67669). The NPRM was prompted by a 

report from GE of a manufacturing 

quality escape that identified a certain 

population of HPT rotor stage 1 disks 

that did not meet the design 

specification. GE determined that 

machining and inspection of the 

affected HPT rotor stage 1 disks was 

inconsistent with the engineering 

drawing. Further analysis by GE 

determined that the nonconformance at 

the forward and aft hooks of the HPT 

rotor stage 1 disks may cause the disks 

to fail prematurely and, therefore, the 

life limit of the affected HPT rotor stage 

1 disks requires reduction. As a result, 

GE decreased the life limit of the 

affected HPT rotor stage 1 disks. In the 

NPRM, the FAA proposed to require 

revising the ALS of the GE Passport 20 

Line Maintenance Manual, GEK 112062, 

and the operator’s existing approved 

CAMP to incorporate a reduced life 

limit for certain HPT rotor stage 1 disks. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received one comment, from 

GE. The following presents the 

comment received on the NPRM and the 

FAA’s response. 

Request To Update Date of Service 

Information 

GE requested that the FAA correct the 

date of GE Service Bulletin (SB) 

PASSPORT20–A–72–00–0116–00A– 

930A–D, Issue 002, in this AD from July 

22, 2021, to August 13, 2021. GE 

commented that the NPRM included the 

date of the draft SB and not the date of 

the published SB. GE stated that there 

was no change to the document content 

between the draft and publication dates. 

The FAA agrees and has revised this 

AD as requested. 

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 and any other changes 

described previously, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator.

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed GE SB 

PASSPORT20–A–72–00–0116–00A– 

930A–D, Issue 002, dated August 13, 

2021. This service information describes 

procedures for removing a certain 

population of HPT rotor stage 1 disks 

from service and provides serial 

numbers of the affected HPT rotor stage 

1 disks. 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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 78 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 

Revise the ALS of the Line Maintenance Manual and the operator’s existing approved CAMP.1 work-hour × $85 per hour = 

$85.

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. 

List of Subjects in 14 CFR Part 39

The Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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 adding 

the following new airworthiness 

directive: 

2022–03–19 General Electric Company: 

Amendment 39–21936; Docket No. 

FAA–2021–1016; Project Identifier AD– 

2021–00625–E. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective March 21, 2022. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to General Electric 

Company (GE) Passport 20–17BB1A, Passport 

20–18BB1A, and Passport 20–19BB1A model 

turbofan engines. 

(d) Subject 

Joint Aircraft System Component (JASC) 

Code 7250, Turbine Section. 

(e) Unsafe Condition 

This AD was prompted by a manufacturing 

quality escape that requires a reduction to the 

life limit for certain high-pressure turbine 

(HPT) rotor stage 1 disks. The FAA is issuing 

this AD to prevent failure of the HPT rotor 

stage 1 disk. The unsafe condition, if not 

addressed, could result in uncontained disk 

release, damage to the engine, and damage to 

the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Action 

Within 120 days after the effective date of 

this AD, revise the airworthiness limitations 

section of the existing maintenance manual 

for your engine and the operator’s existing 

approved continuous airworthiness 

maintenance program by adding Figure 1 to 

paragraph (g) of this AD.

Airworthiness Directives; Airbus 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2014–21– 

03, which applied to Airbus Helicopters 

Model AS332L2 helicopters with a 

certain yaw control damper support 

(support) installed. AD 2014–21–03 

required repetitively inspecting the 

support attachment points for a crack. 

Since the FAA issued AD 2014–21–03, 

an improved (reinforced) support was 

developed. This AD retains the 

inspection requirements of AD 2014– 

21–03 and requires installing the 

improved support as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is incorporated by 

reference. The FAA is issuing this AD 

to address the unsafe condition on these 

products. 

DATES: This AD becomes effective 

March 1, 2022.
