NTSB Narrative Summary Released at Completion of Accident

The airplane's nose gear collapsed while landing. The airplane bounced upon touchdown and continued to porpoise down the runway. The nose gear fork separated from the lower strut, resulting in the nose impacting the runway. Examination of the nose tire revealed a flat spot and several cuts surrounding it. The nose wheel was broken and pieces of the wheel penetrated the tire, destroying the inner tube.

NTSB Probable Cause Narrative

the pilot's improper flare and inadequate recovery from a bounced landing, which resulted in a collapse of the nose landing gear.
