a report that operators may not have been 

provided with enough data to determine the 

accumulated life of certain propeller shafts. 

The FAA is issuing this AD to prevent the

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) For affected M601F model turboprop 

engines, before the propeller shaft 

accumulates 12,000 flight hours (FHs) since 

first installation on an engine, or before 

accumulating 350 FHs after the effective date 

of this AD, whichever occurs later, remove 

the propeller shaft and replace with a part 

eligible for installation. 

(2) For affected M601D–11, M601E–11, 

M601E–11A, M601E–11AS, and M601E–11S

of this AD, calculate the total time since new 

of the propeller shaft in accordance with the 

Accomplishment Instructions, section 2.2 

Group 2 Engines, paragraph 1., of the ASB. 

(ii) Remove the propeller shaft prior to 

reaching its applicable life limit and replace 

with a part eligible for installation in 

accordance with the Accomplishment 

Instructions, section 2.2 Group 2 Engines, 

paragraph 2., of the ASB. 

(h) Definitions

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Saab AB, Support and Services Model 

340A (SAAB/SF340A) and SAAB 340B 

airplanes. This AD was prompted by a 

report that there is no evidence that 

post-machining stress relief or deembrittlement post-cadmium plating 

treatments were performed on certain 

torque arm center pins. This AD 

requires replacing each affected torque 

arm center pin on the main landing gear 

(MLG), as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is incorporated by reference. 

This AD also prohibits the installation 

of affected parts. The FAA is issuing 

this AD to address the unsafe condition 

on these products. 

DATES: This AD is effective August 18, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 18, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0273, 

dated December 8, 2021 (EASA AD 

2021–0273) (also referred to as the 

MCAI), to correct an unsafe condition 

for certain Saab AB, Support and 

Services Model 340A (SAAB/SF340A) 

and SAAB 340B airplanes. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Saab AB, Support and 

Services Model 340A (SAAB/SF340A) 

and SAAB 340B airplanes. The NPRM 

published in the Federal Register on 

May 6, 2022 (87 FR 27035). The NPRM 

was prompted by a report that there is 

no evidence that post-machining stress 

relief or de-embrittlement postcadmium plating treatments were 

performed on certain torque arm center 

pins. The NPRM proposed to require 

replacing each affected torque arm 

center pin on the MLG, as specified in 

EASA AD 2021–0273. The NPRM also 

proposed to prohibit the installation of 

affected parts. 

The FAA is issuing this AD to address 

untreated torque arm center pins 

installed on any MLG, which, if not 

corrected, could lead to failure of the 

torque arm center pin and free swinging 

of the MLG, possibly resulting in loss of 

control of the airplane on ground, or 

loss of the MLG hydraulic braking 

function. See the MCAI for additional 

background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the cost to the public. 

Conclusion 

The FAA reviewed the relevant data 

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 2021–0273 specifies 

procedures for replacing each affected 

torque arm center pin on the MLG. 

EASA AD 2021–0273 also prohibits the 

installation of affected parts. 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 43 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators * 

8 work-hours × $85 per hour = $680 .......................................................................................... $2,839 $3,519 $151,317 

* According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the 

cost estimate. 

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.

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as
