(ii) The specimen set must have a 

minimum of ten (10) flaws which 

provide an acoustic response similar to 

PWSCC indications. All flaws must be 

greater than 10 percent of the nominal 

pipe wall thickness. A minimum of 20 

percent of the total flaws must initiate 

from the inside surface and 20 percent 

from the outside surface. At least 20 

percent of the flaws must be in the 

depth ranges of 10–30 percent through 

wall thickness and at least 20 percent 

within a depth range of 31–50 percent

Airworthiness Directives; Pilatus 

Aircraft Limited Model PC–7 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

This Airworthiness Directive (AD) is 

prompted due to reported corrosion on the 

bolts and in the bores of the attachment 

fittings for the engine mounting frame. The 

corrosion is caused by damaged cadmium 

plating of the bolts or damaged surface finish 

of the attachment fitting. 

Such a condition, if left uncorrected, could 

lead to crack initiation at the bolt and the 

fitting bore and subsequently to the failure of 

the engine attachment fitting. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

September 9, 2009. 

On September 9, 2009, the Director of 

the Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on June 5, 2009 (74 FR 26994). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

This Airworthiness Directive (AD) is 

prompted due to reported corrosion on the 

bolts and in the bores of the attachment 

fittings for the engine mounting frame. The 

corrosion is caused by damaged cadmium 

plating of the bolts or damaged surface finish 

of the attachment fitting. 

Such a condition, if left uncorrected, could 

lead to crack initiation at the bolt and the 

fitting bore and subsequently to the failure of 

the engine attachment fitting. 

In order to correct and control the 

situation, this AD requires a visual 

inspection of the relevant bolts and fittings. 

Additionally, the replacement of the bolts is 

required. 

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 available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

10 products of U.S. registry. We also 

estimate that it will take about 4.5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $80 per work-hour. 

Required parts will cost about $300 per 

product. 

Based on these figures, we estimate 

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

to be $6,600 or $660 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 

We determined that 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 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); and 


srobinson on DSKHWCL6B1PROD with RULES
Federal Register / Vol. 74, No. 149 / Wednesday, August 5, 2009 / Rules and Regulations 38895 

(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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD Docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through
