figures discussed in AD rulemaking 

actions represent only the time 

necessary to perform the specific actions 

actually required by the AD. These 

figures typically do not include 

incidental costs, such as the time 

required to gain access and close up, 

planning time, or time necessitated by 

other administrative actions. 

Regulatory Impact 

The regulations adopted herein 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. Therefore, it is 

determined that this final rule does not 

have federalism implications under 

Executive Order 13132. 

For the reasons discussed above, I 

certify that this action (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 (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. A final evaluation has 

been prepared for this action and it is 

contained in the Rules Docket. A copy 

of it may be obtained from the Rules 

Docket at the location provided under

SUPPLEMENTARY INFORMATION: A 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an airworthiness directive (AD) 

that is applicable to certain Saab Model 

SAAB SF340A series airplanes was 

published in the Federal Register on 

April 1, 2004 (69 FR 17072). That action 

proposed to require replacing certain 

power wires with a modification 

harness; and testing the new harness 

installation. 

Comments 

Interested persons have been afforded 

an opportunity to participate in the 

making of this amendment. No 

comments were submitted in response 

to the proposal or the FAA’s 

determination of the cost to the public. 

Conclusion 

The FAA has determined that air 

safety and the public interest require the 

adoption of the rule as proposed. 

Cost Impact 

The FAA estimates that 12 airplanes 

of U.S. registry will be affected by this 

AD, that it will take approximately 30 

work hours per airplane to accomplish 

the required actions, and that the 

average labor rate is $65 per work hour. 

Required parts will cost approximately 

$5,500 per airplane. Based on these 

figures, the cost impact of the AD on 

U.S. operators is estimated to be 

$89,400, or $7,450 per airplane. 

The cost impact figure discussed 

above is based on assumptions that no 

operator has yet accomplished any of 

the requirements of this AD action, and 

that no operator would accomplish 

those actions in the future if this AD 

were not adopted. The cost impact 

figures discussed in AD rulemaking 

actions represent only the time 

necessary to perform the specific actions 

actually required by the AD. These 

figures typically do not include 

incidental costs, such as the time 

required to gain access and close up, 

planning time, or time necessitated by 

other administrative actions. 

Regulatory Impact 

The regulations adopted herein 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. Therefore, it is 

determined that this final rule does not 

have federalism implications under 

Executive Order 13132. 

For the reasons discussed above, I 

certify that this action (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 (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. A final evaluation has 

been prepared for this action and it is 

contained in the Rules Docket. A copy 

of it may be obtained from the Rules 

Docket at the location provided under

SUPPLEMENTARY INFORMATION: A 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an airworthiness directive (AD) 

that is applicable to all BAE Systems 

(Operations) Limited (Jetstream) Model 

4101 airplanes was published in the 

Federal Register on October 1, 2003 (68 

FR 56596). That action proposed to 

require various inspections of the 

fuselage nose structure between stations 

4 and 11, and corrective actions if 

necessary. 

Comments 

Interested persons have been afforded 

an opportunity to participate in the 

making of this amendment. Due 

consideration has been given to the 

comments received from a single 

commenter. 

Request To Withdraw Proposed AD 

The commenter, an operator, states 

that the proposed AD is an unnecessary 

burden to operators. The commenter 

suggests that instead of the FAA issuing 

an AD, the maintenance review board 

(MRB) report should be revised to 

include the actions required by the 

proposed AD. The commenter states 

that it currently performs numerous 

inspections for cracking on its fleet of 

Jetstream Model 4101 airplanes using 

procedures specified in the commenter’s 

maintenance programs. The commenter 

notes that BAE Systems (Operations) 

Limited Service Bulletin J41–53–047, 

Revision 1, dated July 19, 2002, 

specifies that when the inspections and 

procedures in the service bulletin are 

published in the MRB report and the 

maintenance planning document (MPD), 

the inspections and procedures will be 

deleted from the service bulletin and the 

MRB report will become the published 

source document. The commenter also 

notes that another operator, with a fleet 

of 27 Jetstream Model 4101 airplanes, 

did the inspections specified in the 

service bulletin and did not find any 

cracking. Compliance with the proposed 

AD would require the commenter to 

bring 25 airplanes ‘‘off-line’’ to access 

and inspect the areas specified in the 

proposed AD. The commenter states 

that if the inspection procedures were 

added to the MRB report through a 

revision, an operator could merge these 

inspections into its established 

maintenance program so the inspections 

coincide with the operator’s heavy 

maintenance program, which would 

reduce the operational impact. 

The FAA infers that the commenter is 

requesting that the AD be withdrawn. 

We do not agree. The procedures 

specified in operators’ MRB reports are 

not mandatory. Therefore, we must 

issue an AD to ensure that the identified 

unsafe condition is properly addressed. 

We acknowledge that some operators 

may currently have maintenance 

programs that address the unsafe 

condition. If a program is adequate, an 

operator would be in a position to 

request approval for an alternative 

method of compliance with the AD (i.e., 

to follow the operator’s current program 

rather than revise it to comply with the 

AD). Our obligation to issue the AD and 

address an unsafe condition remains; 

the rule must apply to everyone to 

ensure that all affected airplanes are 

covered, regardless of who operates 

them. Furthermore, the airworthiness 

authority for the state of design issued 

an airworthiness directive mandating 

the same actions required by this AD. 

This AD has not been changed regarding 

this issue. 

Request To Revise Cost Impact Section 

The commenter notes that the figure 

in the Cost Impact section of the 

proposed AD does not include 

incidental costs, such as the time 

required to gain access and close up an 

airplane. The commenter states that 

these costs are not incidental, and that 

the majority of time required to perform 

the various inspections is spent 

accessing the areas to be inspected.

We infer that the commenter is 

requesting that the Cost Impact section 

of the proposed AD be revised. We do 

not agree. As stated in the proposed AD, 

‘‘the figures discussed in AD rulemaking 

actions represent only the time 

necessary to perform the specific actions 

actually required by the AD.’’ The 

specific actions required by the AD are 

various inspections of the fuselage nose 

structure between stations 4 and 11. We 

expect that most operators will be able 

to do the actions required by this AD 

during scheduled maintenance. We 

attempt to set compliance times that 

generally coincide with operators’

maintenance schedules. However, 

because operators’ schedules vary 

substantially, we cannot accommodate 

every operator’s optimal scheduling in 

each AD. The time necessary for gaining 

access to and closing the inspection area 

is incidental. This AD has not been 

changed regarding this issue. 

The commenter also objects to the 

FAA’s assumption that ‘‘no operator 

would accomplish those actions in the 

future if this AD were not adopted.’’ The
