The NTSB's narrative final · quoted from the NTSB record
The pilot attempted to land, but had to execute a go-around because the airplane was too fast and far down the runway. During the second landing attempt, the airplane touched down about half way down the runway and bounced. As the airplane reached the departure end of the runway, the pilot steered the airplane off into vegetation which resulted in substantial damage to the fuselage, wings, and empennage.
