# ACTION:

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

# SUMMARY:

This document announces the reopening of the comment period for the above-referenced NPRM, which proposed the adoption of a new airworthiness directive (AD) that applies to The Boeing Company Model 747 airplanes equipped with a main deck side cargo door (MDSCD). The NPRM proposed to require revising the airplane flight manual to incorporate limitations for carrying certain payloads. This reopening of the comment period is necessary to ensure that all interested persons have ample opportunity to submit any written relevant data, views, or arguments regarding the proposed requirements of the NPRM.

# SUPPLEMENTARY INFORMATION:

                     We proposed to amend 14 CFR part 39 by adding a notice of proposed rulemaking (NPRM) that would apply to The Boeing Company Model 747 airplanes equipped with an MDSCD. The NPRM was published in the                     **Federal Register**                     on December 1, 2014 (79 FR 71037). The NPRM proposed to require revising the airplane flight manual to incorporate limitations for carrying certain payloads. The NPRM also invites comments on its overall regulatory, economic, environmental, and energy aspects.                

## Events Leading to the Reopening of the Comment Period

Since we issued the NPRM (79 FR 71037, December 1, 2014), several commenters have requested that the comment period be extended/reopened to provide additional time to comment on the merits of the proposal.

## FAA's Determination

We found it appropriate to reopen the comment period to give all interested persons additional time to examine the proposed requirements of the NPRM (79 FR 71037, December 1, 2014) and submit comments. We have determined that reopening the comment period for 30 days will not compromise the safety of these airplanes.

## Extension of Comment Period

The comment period for Docket No. FAA-2014-0780, Directorate Identifier 2014-NM-168-AD, has been revised. The comment period now closes March 2, 2015.

                    No other part of the regulatory information has been changed; therefore, the NPRM (79 FR 71037, December 1, 2014) is not republished in the                     **Federal Register**                    .                

Issued in Renton, Washington, on January 16, 2015.

Manager, Transport Airplane Directorate, Aircraft Certification Service.
