The NTSB's narrative final · quoted from the NTSB record
The pilot of the tailwheel-equipped airplane reported that, during landing, the airplane bounced, so he applied power for a go-around. He added that the airplane "immediately banked left sharply." He attempted to recover by using rudder and aileron inputs, but the airplane impacted terrain. 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. A review of recorded data from the automated weather observation station located on the airport revealed that, about 5 minutes before the accident, the wind was calm. The airplane was landing on runway 34.
