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.

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, EASA AD 2021–0127. 

(h) Exceptions to EASA AD 2021–0127 

(1) Where EASA AD 2021–0127 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(2) The ‘‘Remarks’’ section of EASA AD 

2021–0127 does not apply to this AD. 

(3) Where EASA AD 2021–0127 requires 

modifying the airplanes and specifies the 

modification ‘‘can be accomplished in 

accordance with the instructions of the SB,’’ 

for this AD, replace the text ‘‘the instructions 

of the SB’’ with ‘‘paragraphs 3.C. and 3.E. of 

the Accomplishment Instructions of the SB.’’

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0136, 

dated June 4, 2021 (EASA AD 2021– 

0136) (also referred to as the MCAI), to 

correct an unsafe condition for all 

Airbus SAS A330–201, A330–202, 

A330–203, A330–223, A330–243, A330– 

301, A330–302, A330–303, A330–321, 

A330–322, A330–323, A330–341, A330– 

342, A330–343, A330–841, A330–941, 

A340–211, A340–212, A340–213, A340– 

311, A340–312, A340–313, A340–541, 

A340–542, A340–642, and A340–643 

airplanes. Model A340–542 and A340– 

643 airplanes are not certificated by the 

FAA and are not included on the U.S. 

type certificate data sheet; this AD 

therefore does not include those 

airplanes in the applicability. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Airbus SAS Model A330– 

200, –300, –800, and –900 series 

airplanes; and Model A340–200, –300, 

–500, and –600 series airplanes. The 

NPRM published in the Federal 

Register on October 7, 2021 (86 FR 

55747). The NPRM was prompted by 

reports that the instructions on the 

doghouse door lock placard are unclear 

and incomplete. The NPRM proposed 

replacing the placard with an improved 

instruction placard, as specified in 

EASA AD 2021–0136. The NPRM also 

proposed to prohibit the installation of 

affected parts under certain conditions. 

The FAA is issuing this AD to address 

possible incorrect operation of the 

doghouse door lock due to unclear and 

incomplete handling instructions on the 

door placard installed near the lock. 

This condition, if not addressed, could 

lead to failure of the latch, which could 

block the door in the closed position 

and prevent access to the emergency 

equipment inside the doghouse. See the 

MCAI for additional background 

information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from the 

Air Line Pilots Association, 

International (ALPA) who supported the 

NPRM without change. 

The FAA received an additional 

comment from Delta Air Lines (DAL). 

The following presents the comments 

received on the NPRM and the FAA’s 

response. 

Request for Exception to Required Part 

DAL requested an exception to allow 

the use of internally manufactured 

placards having the same text and font 

size as the Diehl placard, part number 

(P/N) 1500500–00C844, specified in the 

Diehl Aviation service information 

referenced in EASA AD 2021–0136. 

DAL stated that if one of the installed 

Diehl placards were missing or 

damaged, alternate placard sources may 

be able to provide replacements faster 

while maintaining an acceptable level of 

safety. 

The FAA does not agree with the 

requested exception. This AD mandates 

the use of a placard, P/N 1500500– 

00C844, specified in the Diehl Aviation 

service information. Operators may 

request to use an alternate placard 

through the alternative method of 

compliance (AMOC) process specified 

in the provisions of paragraph (i)(1) of 

this AD. Operators should provide 

justification that such an alternate 

placard meets all airworthiness 

requirements, not only that the placard 

would have the same text and font size. 

This AD has not been changed with 

regard to this request. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comments received, and 

determined that air safety requires 

adopting this AD as proposed. 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. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0136 specifies 

procedures for replacing the instruction 

placard on the passenger cabin 

doghouse door. EASA AD 2021–0136 

also prohibits the installation of 

doghouses with incorrect instruction 

placards. 

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 62 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 


jspears on DSK121TN23PROD with RULES1
Federal Register / Vol. 87, No. 30 / Monday, February 14, 2022 / Rules and Regulations 8171 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per product Cost on U.S. 

operators 

2 work-hours × $85 per hour = 

$170.

Up to $95 per placard .................. Up to $265 per placard ................ Up to $16,430.* 

* Assuming one placard per product. The number of placards on an airplane depends on the passenger configuration and varies from operator 

to operator. 

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.

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.
