Incident Overview
A pilot encountered multiple system failures during flight, including trouble with radios, electrical system, fuel and engine gauges, and the ammeter. In response, the pilot turned off all electrical equipment and prepared for an emergency landing. Concerned about potential fuel exhaustion, the pilot maintained a close spacing behind another aircraft in the landing pattern. During the flare, the aircraft encountered wake turbulence, causing the right wing to strike the ground. The aircraft subsequently slid to a stop.
Post-Accident Examination
An examination of the aircraft after the incident revealed a dead battery, a faulty battery contactor, and that the starter was engaged. Following repairs, a test flight was conducted. During this test flight, the alternator control unit malfunctioned. The component was replaced, and no further discrepancies were noted.
