The NTSB's narrative final · quoted from the NTSB record

THE DESIGNATED EXAMINER WAS GIVING THE STUDENT PILOT HIS PRIVATE PILOT EXAMINATION FLIGHT CHECK. DURING A SOFT FIELD LANDING DEMONSTRATION BY THE STUDENT, THE GEAR WAS LOWERED AND THE GEAR HANDLE WAS VERIFIED DOWN BY BOTH PILOTS. HOWEVER, NEITHER PILOT VERIFIED THE GEAR VIA THE GEAR LIGHT. THE GEAR WARNING SOUNDED DURING FINAL APPROACH, BUT BOTH PILOTS MISIDENTIFIED IT AS A STALL WARNING. THE AIRCRAFT WAS LANDED WITH THE GEAR UP AND THE GEAR DOORS PARTIALLY OPENED. THE LANDING GEAR MOTOR HAD FAILED AND THE CIRCUIT BREAKER WAS POPPED.
