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

During takeoff the #2 wheel separated from the left main landing gear assembly. A company mechanic stated that during a walk-around inspection he noted the #1 and #2 main landing gear tires needed to be replaced. The #1 & #2 tires are on the left main landing gear assembly; with the #1 tire being outboard of the #2 tire. The mechanic reported, "We removed & replaced #2 main landing gear [tire], with nothing unusual during the tire change." The axle nut/spacer assembly was found with the wheel. The axle nut lock-bolts were found installed in the axle nut/spacer assembly with safety wire connecting the lock-bolts to the axle nut. The lock-bolts were not damaged. The interfacing threads between the axle nut/spacer assembly and the axle were not stripped and the treads were not worn. A demonstration of a wheel installation and a review of the installation procedures were performed at the request of the NTSB. In order for the lock-bolts to engage the axle keyslot, the axle nut/spacer assembly had to be properly torqued and wheel bearings seated.
