Introduction

This Amendment No. 3 to Schedule 13D (this “Amendment”) amends the Schedule 13D initially filed on June 28, 2007 (the “Initial Schedule 13D”), the Amendment No. 1 to Schedule 13D filed on December 14, 2007, as well as the Amendment No. 2 to Schedule 13D filed on January 10, 2008 (collectively, “Schedule 13D”). Except as provided herein, this Amendment does not modify any of the information previously reported on the Schedule 13D. Capitalized terms used and not otherwise defined have the meaning given to them in the Schedule 13D.

Item 1. Security and Issuer.

Item 1 is hereby amended and restated as follows:

This statement on Schedule 13D relates to the common units (the “Common Units”) of Regency Energy Partners LP, a Delaware limited partnership (the “Issuer”). The principal executive offices of the Issuer are located at 1700 Pacific Avenue, Suite 2900, Dallas, Texas 75201. The total number of Common Units reported as beneficially owned in this Amendment is 22,406,830, which constitutes approximately 35.5% of the total number of Common Units outstanding, with the Class E Units having been converted into Common Units, and assuming the Subordinated Units (defined below) were converted into Common Units. This number and percentage is comprised of 17,705,796 subordinated units (the “Subordinated Units”), and 4,701,034 Common Units of the Issuer (the “Common Units”). On April 21, 2008, ASC Hugoton LLC converted 4,701,034 Class E Common Units of the Issuer to 4,701,034 Common Units. The beneficial ownership reported in this Schedule 13D assumes that at the date hereof there were 45,405,054 Common Units outstanding (not including the Subordinated Units but reflecting the conversion of the Class E units). The Common Units represent limited partner interests in the Issuer.

Item 2. Identity and Background.

(a)

This Amendment is filed jointly by each of the following persons pursuant to Rule 13d-1(k) promulgated by the Securities and Exchange Commission pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the “Act”):

	(ii)		EFS Regency GP Holdco II, LLC, a Delaware limited liability company (the “LP Holdings GP,” and collectively with LP Holdings, the “LP Holdings Entities”); and

	(iii)		Aircraft Services Corporation, a Nevada corporation (“ASC”).

	(iv)		ASC Hugoton LLC (“ASC Hugoton”), a Delaware limited liability company

The persons listed in (i) through (iv) above are collectively referred to as the “Reporting Persons.” The Reporting Persons have entered into a Joint Filing Agreement, dated the date hereof, a copy of which is filed with this Amendment as Exhibit A (which is hereby incorporated by reference) pursuant to which the Reporting Persons have agreed to file this statement jointly in accordance with the provisions of Rule 13d-1(k)(1) under the Act. Information with respect to each Reporting Person is given solely by such Reporting Person, and no Reporting Person assumes responsibility for the accuracy or completeness of the information furnished by another Reporting Person. The Reporting Persons expressly disclaim that they have agreed to act as a group other than as described in this Schedule 13D.

Pursuant to Rule 13d-4 of the Act, the Reporting Persons expressly declare that the filing of this statement shall not be construed as an admission that any such person is, for the purposes of Section 13(d) and/or Section 13(g) of the Act or otherwise, the beneficial owner of any securities covered by this Schedule 13D held by any other person.

Certain information required by this Item 2 concerning the executive officers, directors and managers of certain of the Reporting Persons was set forth on Schedule A, attached to the Schedule 13D, which is incorporated herein by reference.
