[Docket No. 2002–NM–182–AD; Amendment 

39–13882; AD 2004–24–06] 

RIN 2120–AA64

Airworthiness Directives; Saab Model 

SAAB SF340A and SAAB 340B Series 

Airplanes

AGENCY: Federal Aviation 

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a 

new airworthiness directive (AD), 

applicable to certain Saab Model SAAB 

SF340A and SAAB 340B series 

airplanes. This AD requires replacement 

of the retract actuator bracket 

attachment bolt (RABAB) of the main 

landing gear (MLG) with a new RABAB; 

reidentification of the MLG shock strut; 

an inspection for corrosion, fretting, or 

other damage of certain RABABs; and 

applicable corrective actions. The 

actions specified by this AD are 

intended to prevent failure of the 

RABAB, which could result in 

loosening of the actuator bracket and 

consequent failure of the MLG to retract, 

with considerable damage to other 

landing gear parts, including the MLG 

trunnion fitting. This action is intended 

to address the identified unsafe 

condition.

DATES: Effective January 4, 2005. 

The incorporation by reference of a 

certain publication listed in the 

regulations is approved by the Director 

of the Federal Register as of January 4, 

2005.

ADDRESSES: The service information 

referenced in this AD may be obtained 

from Saab Aircraft AB, SAAB Aircraft 

Product Support, S–581.88, Linko ̈ping, 

Sweden. This information may be 

examined at the Federal Aviation 

Administration (FAA), Transport 

Airplane Directorate, Rules Docket, 

1601 Lind Avenue, SW., Renton, 

Washington; or at the National Archives 

and Records Administration (NARA).

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 and SAAB 340B series 

airplanes was published as a 

supplemental notice of proposed 

rulemaking (NPRM) in the Federal 

Register on September 28, 2004 (69 FR 

57892). That action proposed to require 

replacement of the retract actuator 

bracket attachment bolt (RABAB) of the 

main landing gear (MLG) with a new 

RABAB; reidentification of the MLG 

shock strut; an inspection for corrosion, 

fretting, or other damage of any RABAB; 

and applicable corrective actions. 

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 

We estimate that approximately 281 

airplanes of U.S. registry will be affected 

by this AD, that it will take 

approximately 7 work hours per 

airplane to accomplish the required 

actions, and that the average labor rate 

is $65 per work hour. Required parts 

will be supplied at no cost by the 

manufacturer. Based on these figures, 

the cost impact of this AD on U.S. 

operators is estimated to be $127,855, or 

$455 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 

the caption ADDRESSES.
