Exhibit 31.2

                    CERTIFICATION OF CHIEF EXECUTIVE OFFICER

I, Eric D. Gadd, certify that:

1.   I have reviewed this annual report on Form 10-K for the fiscal years ended
     December 31, 2002 and 2003 of Zond-PanAero Windsystem Partners I;

2.   Based on my knowledge, this annual report does not contain any untrue
     statement of a material fact or omit to state a material fact necessary to
     make the statements made, in light of the circumstances under which such
     statements were made, not misleading with respect to the period covered by
     this annual report;

3.   Based on my knowledge, the financial statements, and other financial
     information included in this annual report, fairly present in all material
     respects the financial condition, results of operations and cash flows of
     the registrant as of, and for, the periods presented in this annual report;

4.   The registrant's other certifying officer and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15e and 15d-15(e)) for the registrant and we
     have:

     a) Designed such disclosure controls and procedures, or
        caused such disclosure controls and procedures to be designed
        under our supervision, to ensure that material information
        relating to the registrant, including its consolidated
        subsidiaries, is made known to us by others within those
        entities, particularly during the period in which this report is
        being prepared;

    b) Evaluated the effectiveness of the registrant's
       disclosure controls and procedures and presented in this report
       our conclusions about the effectiveness of the disclosure
       controls and procedures, as of the end of the period covered by
       this report based on such evaluation; and

    c) Disclosed in this report any change in the registrant's
       internal control over financial reporting that occurred during
       the registrant's most recent fiscal quarter (the registrant's
       fourth fiscal quarter in the case of an annual report) that has
       materially affected, or is reasonably likely to materially
       affect, the registrant's internal control over financial
       reporting.

5.   The registrant's other certifying officer and I have disclosed, based on
     our most recent evaluation of internal control over financial reporting, to
     the registrant's auditors and the audit committee of the registrant's board
     of directors (or persons performing the equivalent functions):

     a) All significant deficiencies and material weaknesses in
        the design or operation of internal control over financial
        reporting which are reasonably likely to adversely affect the
        registrant's ability to record, process, summarize and report
        financial information; and


<PAGE>

     b) Any fraud, whether or not material, that involves
        management or other employees who have a significant role in the
        registrant's internal control over financial reporting.
