## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

DURING HIS AIRSHOW ROUTINE AT THE KANSAS CITY AVIATION EXPO, THE PILOT EXITED A LOMCEVAK IN AN INVERTED SPIN. HE RECOVERED TO AN UPRIGHT SPIN IN THE OPPOSITE DIRECTION, WHICH CONTINUED TO THE GROUND, IMPACTING TERRAIN NEAR SHOW CENTER. THERE WAS A POST-CRASH FIRE, WHICH INCLUDED AN IMPACT WITH KEROSENE PYROTECHNICS THAT WERE PLACED FOR A SUBSEQUENT DISPLAY BY ANOTHER PERFORMER. THE PILOT WAS FATALLY INJURED IN THE CRASH.AN EXHAUSTIVE EXAMINATION OF THE AIRCRAFT BY AIRWORTHINESS PERSONNEL FROM THIS OFFICE AND BY ENGINEERS FROM THE SMALL AIRPLANE DIRECTORATE DID NOT REVEAL ANY PRE-IMPACT DEFECTS OR MALFUNCTIONS. REVIEW OF EXTENSIVE PHOTOGRAPHIC EVIDENCE SHOW THE CONTROL SURFACES MOVING IN RESPONSE TO PILOT INPUT UP TO IMPACT. A PORTABLE GPS AND ELECTRONIC ENGINE INSTRUMENTATION WERE REMOVED FROM THE WRECKAGE AND FORWARDED TO NTSB FOR POSSIBLE DATA RECOVERY.
