According to the pilot, shortly after takeoff the left "generator light" on the annunciation panel illuminated. He attempted a reset but was unsuccessful. Shortly after that the right generator and battery failed. As the flight progressed, various instruments failed, including radio and navigational instruments. The pilot attempted to manually extend the landing gear but was unable to verify that the gear was down and locked. With the power out the landing gear position lights in the cockpit would not illuminate. Upon landing the nose gear remained extended, but both main gears collapsed. Examination of the airplane by a Federal Aviation Administration inspector found that both the left and right generators had failed with both generators exhibiting thermal damage. No further examination was performed.
Probable Cause: A total failure of the electrical system for undetermined reasons, which resulted in the pilot's inability to ensure that the landing gear was down and locked.
