Our CTLS has just come back from hard landing repair, annual and rubber hose replacement. Yes, we did it all at once since the engine was going to be off the plane anyway. Just before the accident that caused all this work (end of September) one of our club members reported all the electrical systems "shut down". This happened while taxiing to the runway for takeoff. According to the pilot, all avionics, interior and exterior lights all shut off. The engine was still running so he taxied back to the hanger. There were no abnormal readings or alarms prior to the failure. The next day all powered up and worked as expected. A day or two later the plane had a hard landing that took it out of service for three months. While down I had the A&P replace the 5 year old battery and generator breakers thinking one of them could be going bad and causing the electrical failure. The aircraft was put back into service last Sunday. I flew for an hour without trouble. One day later, the same pilot who had experienced electrical failure last time had it happen again. This time while warming the engine in front of our hanger. He reports that the engine continued to run so he spent some time cycling breakers with no effect. When he shut down the engine to "start from scratch" he says the engine wouldn't even turn over. No cranking. After an overnight battery charge, all seems to be working again. There have never been alarms or abnormal readings on the EMS. We're looking for where to start to identify this problem. Any ideas? Stuart Rauh
