As reported to the FAA. Reports are unverified, and codes are left as the FAA publishes them.

What was found

RIGHT MAIN GEN FAILED IN FLIGHT. REPORTING THE EVENT BECAUSE WHEN THE GEN SEIZED, THE QUILL SHAFT DID NOT BREAK AWAY. THE GEN QAD MOUNT BROKE & THE GEN WAS FOUND ATTACHED BY THE WIRING & THE COOLING DUCT WITH THE QUILL SHAFT HANGING IN THE DRIVE ADAPTER RECESS & SUPPORTING THE DRIVE END. THERE WAS SLIGHT DAMAGE TO THE ACCESSORY DRIVE FOR THE UNIT, BUT IT IS POSSIBLE THAT THIS COULD HAVE BEEN WORSE AS THE MOUNT GAVE WAY & THE SHAFT CAME OUT OF ITS DRIVE SPLINES OR HAD THE GEN COME COMPLETELY LOOSE. PHOTOS WILL BE SENT.
