Flight and Electrical Malfunction
During the flight, the pilot-in-command observed that the ammeter indicated a discharge. The pilot chose not to divert or land to assess the malfunction, continuing the flight until a total loss of electrical power occurred.
Descent and Landing Gear
At the beginning of the descent from 6,000 feet, the landing gear extended normally. Using a hand-held radio, the pilot asked the tower controller to examine the landing gear, and the controller reported that it appeared down. However, a manual extension of the landing gear was not performed in accordance with the flight manual emergency procedures.
Touchdown and Gear Collapse
After a flyby, the oil pressure gauge went to zero. The pilot then decided to land immediately. Upon touchdown, the nose landing gear and right main landing gear collapsed.
