**SUPPLEMENTARY INFORMATION :**  On February 28, 2012, the U.S. Department of Energy (DOE) published a notice of public meeting (NOPM) and availabilityof framework document for highintensity discharge (HID) lamps, initiating the rulemaking and data collection process to consider establishing energy conservation standards (77 FR 11785). The NOPM requested public comment from interested parties and provided for the submission of comments by April 5, 2012. The National Electrical Manufacturers Association (NEMA), on behalf of itself and its members, requested an extension of the public comment period by one week. NEMA stated that the additional time is necessary to more fully evaluate and prepare the information requested in the NOPM. NEMA stated that the extension will allow NEMA to conduct necessary meetings before providing its comments.

Based on NEMA’s request, DOE believes that extending the comment period to allow additional time for interested parties to prepare and submit comments is appropriate. Therefore, DOE is extending the comment period until April 12, 2012. Accordingly, DOE will consider any comments received by April 12, 2012 to be timely submitted. Issued in Washington, DC, on March 23,

2012. Patrick Davis, Program Manager, Office of Vehicle Technologies, Energy Efficiency and Renewable Energy.

**[Docket No. FAA–2012–0342; Directorate Identifier 2011–SW–028–AD]** 

**RIN 2120–AA64**

**Airworthiness Directives; MD Helicopters, Inc.** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to supersede an existing airworthiness directive (AD) for MD Helicopters, Inc. (MDHI) Model MD900 helicopters. The existing AD requires a visual inspection, and if necessary, an eddy current inspection of the main rotor lower hub assembly (lower hub) for a crack. If a crack exists, the AD requires replacing the lower hub with an airworthy lower hub before further flight. Because that AD was immediately effective, we did notinclude in its requirements certain longterm actions that did not necessitate adoption prior to public comment. Thisproposed AD would require those longterm actions. This proposed AD would require the same inspections as the existing AD but would also require recurring inspections and replacing the lower hub with an airworthy lower hub. We are proposing this AD to detect a crack in the lower hub and prevent failure of the lower hub and subsequent loss of control of the helicopter.

**DATES :**  We must receive comments on this proposed AD by May 29, 2012.

**ADDRESSES :**  You may send comments by any of the following methods:

• Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your comments electronically.

• Fax: 202–493–2251.
