Airworthiness Directives; Learjet Inc. 

Model 45 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD requires 

replacing aluminum fire extinguisher 

discharge tubes with new, improved 

tubes; checking the fire extinguisher 

container for certain serial numbers; 

replacing fire extinguisher containers 

that have affected serial numbers; 

inspecting the pressure indicator on 

certain fire extinguisher containers for 

discrepancies; and performing 

corrective action if necessary. This AD 

was prompted by a report of accidental 

discharge of a fire extinguisher 

container and damage to an aluminum 

discharge tube. Investigation revealed 

that following the discharge an 

inaccurate pressure indication, due to 

the indicator dial being incorrectly 

staked, showed that the container was 

fully charged. We are issuing this AD to 

prevent inaccurate pressure readings 

and subsequent damage to the discharge 

tubes during operation, which could 

result in failure of the fire extinguisher 

system and an uncontained fire in an 

emergency situation. 

DATES: This AD is effective November 

18, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of November 18, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to the 

specified products. That NPRM was 

published in the Federal Register on 

July 7, 2010 (75 FR 38941). That NPRM 

proposed to require replacing aluminum 

fire extinguisher discharge tubes with 

new, improved tubes; checking the fire 

extinguisher container for certain serial 

numbers; replacing fire extinguisher 

containers that have affected serial 


emcdonald on DSK2BSOYB1PROD with RULES
Federal Register / Vol. 75, No. 198 / Thursday, October 14, 2010 / Rules and Regulations 63065 

numbers; inspecting the pressure 

indicator on certain fire extinguisher 

containers for discrepancies; and 

performing corrective action if 

necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

We estimate that this AD affects 322 

airplanes of U.S. registry. We also 

estimate that it will take 5 work-hours 

per product to comply with this AD. 

The average labor rate is $85 per workhour. Required parts cost is minimal. 

Where the service information lists 

required parts costs that are covered 

under warranty, we have assumed that 

there will be no charge for these costs. 

As we do not control warranty coverage 

for affected parties, some parties may 

incur costs higher than estimated here. 

Based on these figures, we estimate the 

cost of this AD to the U.S. operators to 

be $136,850, or $425 per product. 

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 

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) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation 

in Alaska, 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.

SUPPLEMENTARY INFORMATION: 

History 

On July 29, 2010, the FAA published 

in the Federal Register a notice of 

proposed rulemaking to establish 

controlled airspace at Clifton/Morenci, 

AZ (75 FR 44725). Interested parties 

were invited to participate in this 

rulemaking effort by submitting written 

comments on the proposal to the FAA. 

No comments were received. 

Class E airspace designations are 

published in paragraph 6005 of FAA 

Order 7400.9U dated August 18, 2010, 

and effective September 15, 2010, which 

is incorporated by reference in 14 CFR 

Part 71.1. The Class E airspace 

designations listed in this document 

will be published subsequently in that 

Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) Part 71 by 

establishing Class E airspace extending 

upward from 700 feet above the surface, 

at Greenlee County Airport, Clifton/ 

Morenci, CA, to accommodate IFR 

aircraft executing new RNAV (GPS) 

SIAPs at the airport. This action is 

necessary for the safety and 

management of IFR operations. 

The FAA has determined this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (1) Is 

not a ‘‘significant regulatory action’’ 

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under DOT
