14 CFR Part 39

[Docket No. FAA-2007-29337; Directorate Identifier 2007-NM-150-AD]
RIN 2120-AA64


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.

2007.

SUPPLEMENTARY INFORMATION: We proposed to amend 14 CFR part 39 with a 
notice of proposed rulemaking (NPRM) for an AD for all BAE Systems 
(Operations) Limited Model BAe 146 and Model Avro 146-RJ airplanes. 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.

    Issued in Renton, Washington, on November 8, 2007.
