14 CFR Part 39

[Docket No. FAA-2007-29331; Directorate Identifier 2007-NM-136-AD]
RIN 2120-AA64


Airworthiness Directives; Saab Model SAAB-Fairchild SF340A (SAAB/
SF340A) and SAAB 340B Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM); reopening of comment 
period.

-----------------------------------------------------------------------

SUMMARY: This document announces a reopening of the comment period for 
the above-referenced NPRM. The NPRM proposed the adoption of a new 
airworthiness directive for certain Saab Model SAAB-Fairchild SF340A 
(SAAB/SF340A) and SAAB 340B airplanes. That NPRM invited comments 
concerning the proposed requirements for doing repetitive ultrasonic 
inspections to detect cracking in the axle adaptor, replacing the axle 
adaptor if necessary, and ultimately doing the terminating action of 
inspecting and modifying the main landing gear shock strut and axle 
adaptors. This reopening of the comment period is necessary to provide 
additional opportunity for public comment on the proposed requirements 
of that NPRM.

DATES: We must receive comments on this proposed AD by December 20, 
2007.

SUPPLEMENTARY INFORMATION: We proposed to amend 14 CFR part 39 with a 
notice of proposed rulemaking (NPRM) for an AD for certain Saab Model 
SAAB-Fairchild SF340A (SAAB/SF340A) and SAAB 340B airplanes. The NPRM 
was published in the Federal Register on September 28, 2007 (72 FR 
55116). The NPRM proposed to require doing repetitive ultrasonic 
inspections to detect cracking in the axle adaptor, replacing the axle 
adaptor if necessary, and ultimately doing the terminating action of 
inspecting and modifying the main landing gear shock strut and axle 
adaptors. The NPRM action invites comments on the overall regulatory, 
economic, environmental, and energy aspects of the proposed AD.

Actions Since NPRM Was Issued

    Since we issued the NPRM, the DOT's Docket Management System (DMS) 
was replaced by the Federal Docket Management System (FDMS). FDMS is a 
government-wide, electronic docket management system, which contains 
the public dockets and is the method used for submitting comments on 
the overall regulatory, economic, environmental, and energy aspects of 
proposed rulemaking actions. However, due to the service disruption 
caused by the transition from DOT's DMS to the FDMS, the docket 
material was not posted on the FDMS until November 1, 2007. Therefore, 
we have determined that the public was not provided adequate 
opportunity to submit comments on the NPRM. As a result, we have 
decided to reopen the comment period for 30 days to receive additional 
comments.
    No part of the regulatory information has been changed; therefore, 
the NPRM is not republished in the Federal Register.

Comments Due Date

    We must receive comments on this AD action by December 20, 2007.

    Issued in Renton, Washington, on November 8, 2007.
Ali Bahrami,
Manager, Transport Airplane Directorate, Aircraft Certification 
Service.
