Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The private pilot reported that, while en route in the airplane, a “puff of smoke” originated from the instrument panel, so he decided to conduct a precautionary landing at a nearby airport. While on final approach to land, the airplane stalled and then impacted the ground hard just short of the runway. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
