The NTSB's narrative final · quoted from the NTSB record

The pilot had been cleared to enter the class B airspace surrounding the Salt Lake City International Airport, and was southbound over Interstate Highway 15 at 5,500 feet mean sea level. When he was about 3 miles northeast of the airport, he noticed an eagle soaring at his altitude and at his 1 o'clock position. As the eagle drew closer, the pilot made an evasive turn to the left, but the eagle struck the right wing about 18 inches inboard of the wing tip. The airplane landed on runway 32 without further incident. Postaccident inspection by an FAA airworthiness inspector disclosed wing spar damage.
