While climbing through FL150 the electrical system of the aircraft completely failed. The crew switched to VFR and diverted to Lausanne (LSGL).
Conclusions
Ten minutes into the flight, all three cockpit displays failed. The flight crew immediately undertook a visual approach to the nearest airport. This was successful, whereby the emergency instruments that were powered independently of the aircraft’s electrical system, the backup navigation on the iPads, the pilot’s handheld radio, the good weather conditions and the fact that air traffic control kept the airspace clear were contributing factors.
The investigation showed that this failure was not due to a technical defect. After starting the left engine, the three-position switch IGNITION AND ENGINE START was erroneously left in the ON position, which caused the battery to discharge. This error went unnoticed by both pilots, because they did not work their way consistently through the procedural specifications and failed to notice the corresponding warnings and displays.
