The NTSB's narrative final · quoted from the NTSB record
The pilot reported that on final approach to the runway, the airplane was high on the glide slope, so he increased the flap setting to 40 degrees. He stated that he flew past the numbers and fixed distance marker, then initiated a flare. Also, the pilot reported, 'Flared high, banged hard on the two main wheels. Bounced up and came down again. Bounced about 5 more times.' On the fifth bounce the nose gear broke off. The pilot reported that the airplane veered off the prepared runway surface, crossed a taxiway, into a grass section between the taxiway and runway 8. After reaching the grass section, the airplane nosed over and came to rest inverted.
