Incident Overview
According to the pilot's report, the landing approach was normal until touchdown. The pilot stated that the airplane touched down further down the runway than intended, resulting in two porpoising events during the touchdown phase. After the second porpoise, the pilot decided to abort the landing and perform a go-around due to diminishing runway length.
Go-Around Sequence
During the go-around, the pilot retracted the flaps from the full setting to neutral, applied full engine power, and added right rudder input. However, the pilot reported that the airplane subsequently developed a left yaw and roll during the go-around. The aircraft then departed the runway environment.
Post-Impact Events
The airplane contacted a hangar structure, a chain link fence, and a ditch. Following these impacts, the aircraft spun 180 degrees before sliding to a stop. The pilot did not specify the extent of damage to the airplane or the hangar, nor any injuries to persons on the ground.
Pilot Actions
The pilot's account indicates that the decision to go-around was made after two porpoises and recognition of insufficient runway remaining. The flap retraction from full to neutral, combined with full power and right rudder, was part of the go-around procedure. The pilot noted the ensuing left yaw and roll, but no further corrective actions were described.
