Airworthiness Directives; ATR Model ATR42 and ATR72 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 all ATR Model ATR42 and ATR72 airplanes. 
That NPRM invites comments concerning the proposed requirements for 
revising the Airworthiness Limitations Section of the Instructions for 
Continued Airworthiness to incorporate new limitations for fuel tank 
systems. This reopening of the comment period is necessary to provide 
additional opportunity for public comment on the proposed requirements 
of that NPRM.

2007.

SUPPLEMENTARY INFORMATION: We proposed to amend 14 CFR part 39 with a 
notice of proposed rulemaking (NPRM) for an AD for all ATR Model ATR42 
and ATR72 airplanes. The NPRM was published in the Federal Register on 
September 28, 2007 (72 FR 55113). The NPRM proposed to require revising 
the Airworthiness Limitations Section of the Instructions for Continued 
Airworthiness to incorporate new limitations for fuel tank systems. 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 19, 2007.

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