Exhibit 31.2

                    CERTIFICATION OF CHIEF FINANCIAL OFFICER

I, Mary H. Cilia, certify that:

    1.   I have reviewed this quarterly report on Form 10-Q for the
         three months ended September 30, 2003 of Zond-PanAero
         Windsystems Partners I;

    2.   Based on my knowledge, this quarterly 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 quarterly report;

    3.   Based on my knowledge, the financial statements, and other financial
         information included in this quarterly 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 quarterly report;

    4.   The registrant's other certifying officers and I are responsible for
         establishing and maintaining disclosure controls and procedures (as
         defined in Exchange Act Rules 13a-15e) 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
                    quarterly 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

                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.
