Re: Post-Effective Amendment No. 1 for Pacific Dynamix (File Number 333-140881) funded by Separate Account A of Pacific Life Insurance Company (File Number 811-08946); Request for Withdrawal of Registration Statement

Dear Sir or Madam:

Pursuant to Rule 477 of the Securities Act of 1933, as amended, and on behalf of Pacific Life Insurance Company (“Pacific Life”) and Separate Account A of Pacific Life, we hereby request the withdrawal of the Registration Statement on Form N-4 for the Pacific Dynamix Variable Annuity, initially filed with the U.S Securities and Exchange Commission on February 26, 2007 (Accession No. 0000892569-07-000159) and declared effective July 17, 2007.

We request withdrawal of this Registration Statement since Pacific Life did not market the security, no securities were sold in connection with the offering, and Pacific Life will not offer the security in the future. Please note that this request for withdrawal is not meant to extend to the registered status of the separate account, which is the funding vehicle for other variable annuity contracts of the company.

If you have any questions regarding this matter, please contact the undersigned at (949) 219-3943.

Sincerely,

/s/ BRANDON J. CAGE
