Item 5.          Other Events.

     Attached hereto as Exhibit 99.1 is the unaudited financial and business
information of Zond-PanAero Windsystem Partners I, a California Limited
Partnership (the "Partnership") for the fiscal year ended December 31, 2002 (the
"Operating Report"). As explained in the Partnership's Current Report on Form
8-K filed with the Securities and Exchange Commission on November 14, 2003,
Arthur Andersen LLP resigned as the auditor of the Partnership on February 5,
2002, and the Partnership has not had an auditor since that date. Accordingly,
the Partnership did not file an Annual Report on Form 10-K for the year ended
December 31, 2002 in accordance with the requirements of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"). Because the Partnership still has
no auditor, it is now providing the Operating Report attached hereto. December
19, 2003 is the date on which the Operating Report was completed.

     The Partnership intends to file as exhibits to Form 8-K operating reports
for the first, second and third quarters of 2003, and for the year ended
December 31, 2003 as soon as practicable, which the Partnership expects will be
by March 31, 2004. Thereafter, the Partnership intends to file quarterly and
annual operating reports using Form 8-K until the Partnership is able to retain
an auditor and recommence filing periodic reports on Forms 10-K and 10-Q.
