The pilots stated that approach and landing were normal. During landing rollout, about 2,000 feet down the runway, the brakes became ineffective. The aircraft continued to roll off the end of the runway, down an embankment, across a 4 lane road, and came to rest in a drainage ditch. Post-crash examination of the main landing gear brakes showed that 3 out of the 4 brake assemblies were worn beyond allowable limits and all 4 antiskid wheel generators were not producing voltage within the allowable limits. The outboard right main tire had failed during landing roll do to the antiskid becoming inoperative due to the low voltage of the wheel generator. The airplane had received an A-1 through A-6 inspection 2 days before the accident and this was the first flight since the inspection. The A-5 inspection requires inspection of the landing gear brake assemblies for wear, cracks, hydraulic leaks, and release.
