What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) At approximately 1735 CDT the pilot of N3818E departed the airport traffic area for 15 minutes. When the pilot returned to the airport he made a left downwind entry for runway 08. The pilot of the ultralight departed the same airport approximately 5 minutes after N3818E and flew around out side the airport traffic pattern for about 10 minutes. Aircraft N3818E was flying 1500 feet above the surface and the ultralight was about 300 to 500 feet above the surface. During this entire flight the sun was slowly approaching the horizon to the west, southwest of the runway centerline. The two aircraft collided in flight as N3818E was on 1/3 mile final at about 300 feet above the terrain. After the collision the two aircraft hung together briefly. Following separation N3818E was able to be flown to a successful landing on the airport while the ultralight descended to the trees and hung up on the tree tops. There were no injuries to the occupants of the aircraft. The sun appears to be the contributin factor to the accident. No further action is to be taken.
