Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ 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 BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ airplanes. That NPRM invites comments concerning the proposed requirements for repetitive detailed visual inspections for corrosion, pitted fasteners, or pillowing of the APU heat shield and surrounding skin and, if applicable, removal of the heat shield and repair. This reopening of the comment period is necessary to provide additional opportunity for public comment on the proposed requirements of that NPRM.

The NPRM was published in the Federal Register on September 28, 2007 (72 FR 55122). The NPRM proposed to require

repetitive detailed visual inspections for corrosion, pitted fasteners, or pillowing of the APU heat shield and surrounding skin and, if applicable, removal of the heat shield and repair. 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.
