45580 Federal Register / Vol. 83, No. 175 / Monday, September 10, 2018 / Proposed Rules 

Regulatory Findings 

We 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, I certify 

this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); 

3. Will not affect intrastate aviation in 

Alaska to the extent that it justifies 

making a regulatory distinction; and 

4. 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. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to participate in this 

rulemaking by submitting written 

comments, data, or views. We also 

invite comments relating to the 

economic, environmental, energy, or 

federalism impacts that might result 

from adopting the proposals in this 

document. The most helpful comments 

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. 

We will file in the docket all 

comments that we receive, as well as a 

report summarizing each substantive 

public contact with FAA personnel 

concerning this proposed rulemaking. 

Before acting on this proposal, we will 

consider all comments we receive on or 

before the closing date for comments. 

We will consider comments filed after 

the comment period has closed if it is 

possible to do so without incurring 

expense or delay. We may change this 

proposal in light of the comments we 

receive. 

Discussion 

We propose to adopt a new AD for 

MDHI Model 600N helicopters with a 

yaw stability augmentation system and 

with a link assembly part number (P/N) 

600N7617–1 installed. This proposed 

AD would require establishing a life 

limit of 15,000 hours time-in-service 

(TIS) for the link assembly. 

This proposed AD is prompted by a 

report from MDHI that during a review 

of the Airworthiness Limitations section 

of the applicable maintenance manual, 

MDHI discovered that it did not include 

a life limit for link assemblies installed 

on MDHI Model 600N helicopters with 

a yaw stability augmentation system. 

Link assembly P/N 600N7617–1, which 

is made of aluminum, is a life-limited 

part with a life limit of 15,000 hours 

TIS. MDHI subsequently revised the 

Airworthiness Limitations section of the 

maintenance manual to include the life 

limit. The proposed actions are 

intended to prevent a link assembly 

remaining in service beyond its life 

limit, which could result in fatigue 

failure, loss of M/R blade pitch control, 

and subsequent loss of helicopter 

control. 

Related Service Information 

We reviewed MDHI CSP–HMI–2 

MDHI Maintenance Manual, Chapter 04, 

Airworthiness Limitations, Revision 47, 

dated September 30, 2016. This service 

information specifies a 15,000-hour TIS 

life limit for link assembly P/N 

600N7617–1 for helicopters with a yaw 

stability augmentation system. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all known relevant 

information and determined that an 

unsafe condition exists and is likely to 

exist or develop on other products of 

these same type designs. 

Proposed AD Requirements 

This proposed AD would require 

creating a component history card or 

equivalent record for each affected link 

assembly, if one does not exist, and 

recording a life limit of 15,000 hours 

TIS. This proposed AD would also 

require determining the hours TIS of the 

link assembly and replacing each link 

assembly that has reached or exceeded 

its life limit. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 26 helicopters of U.S. 

Registry and that labor costs average $85 

a work-hour. Based on these estimates, 

we expect it would take 30 minutes to 

determine the hours TIS of each link 

assembly and update the aircraft records 

for a cost of $85 per helicopter and 

$2,210 for the U.S. fleet. Replacing a 

link assembly, if needed, would require 

2 work-hours, and parts would cost 

$984 for a cost of $1,154 per link per 

helicopter. 

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. 

We are 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 

We 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, I certify 

this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); 

3. Will not affect intrastate aviation in 

Alaska to the extent that it justifies 

making a regulatory distinction; and 

4. 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. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

1The Commission issued the Guides in 1979 (44 

FR 11176 (Feb. 27, 1979)) to replace trade practice 

rules for the nursery industry (16 CFR part 34) first 

promulgated in the 1950’s (23 FR 4803 (June 28, 

1958)). The Guides help marketers avoid making 

claims that are unfair or deceptive under Section 5 

of the FTC Act, 15 U.S.C. 45. Industry guides, such 

as the Nursery Guides, are administrative 

interpretations of laws administered by the 

Commission. They do not have the force of law and 

are not independently enforceable. Failure to follow 

industry guides may result, however, in 

enforcement action under the FTC Act, 15 U.S.C. 

45. In any such action, the Commission must prove 

that the act or practice at issue is unfair or deceptive 

in violation of Section 5 of the FTC Act.

SUPPLEMENTARY INFORMATION: 

I. Background 

The Commission issued the Guides 

for the Nursery Industry in 1979.1 These 

Guides address various sales claims for 

outdoor plants, including 

representations regarding quantity, size, 

grade, kind, species, age, maturity, 

condition, vigor, hardiness, growth 

ability, price, and origin or place where 

grown. The Commission amended the 

Guides in 1994 to update legal 

terminology, and again in 2007 to make 

a technical correction.2

The Commission reviews its rules and 

guides periodically to seek information 

about their costs and benefits to 

consumers and businesses, regulatory 

and economic impact, and general 

effectiveness in protecting consumers 

and helping industry avoid deceptive 

claims. These reviews assist the 

Commission in identifying rules and 

guides that may warrant modification or 

rescission. 

On February 22, 2018, the 

Commission initiated its scheduled 

regulatory review of the Guides and 

solicited public comment on several 

issues.3 Specifically, the Commission 

sought input on, among other things, the 

continuing need for the Guides; their 

economic impact; possible conflict 

between the Guides and state, local, 

federal, or international laws; and the 

effect of any technological, economic, 

environmental, or other industry 

changes. The Commission also solicited 

comment on issues specific to the 

Guides, such as whether the 

Commission should update plant name 

classification references. The 

Commission received one comment, 

discussed below.
