Read the full NTSB narrative
The left main landing gear outboard wheel/brake assembly separated from the airplane during a landing roll. The Captain did not report any difficulties in controlling the airplane. Inspection of the failed axle revealed a crack which originated at the surface of one of the brake flange holes. This crack had previously been repaired. Detailed metallurgical examination of the crack revealed properties consistent with the surface having been heated to an excessive temperature during the repair process.
