The NTSB's narrative final · quoted from the NTSB record
The airplane veered off the runway and collided with a taxiway light, followed by a collision with a hangar. The airplane bounced upon initial touchdown onto the runway. The pilot added power to soften the following touchdown and the airplane veered to the left and collided with a taxiway light and then a hangar. The pilot said that the bi-wing structure of the airplane reduced his forward visibility and made regaining runway alignment difficult. The pilot noted no mechanical problems with the airplane prior to the accident.
