Incident Overview
The flight crew reported that the flight proceeded normally until the landing roll. During the landing roll, the first officer felt the antiskid releasing, and the captain took over the controls. Braking action was initially felt, but then all braking action was lost. The aircraft departed the end of the runway and came to a stop about 200 feet past the departure end, in the grass. The left outboard main tire was blown.
Examination Findings
Examination of the aircraft revealed that the left inboard antiskid valve brake and return lines were crossed. Additionally, the left inboard skid detect circuit was found inoperative. The wiring to the left inboard and left outboard wheel speed transducers was also crossed. There was also evidence that the aircraft had hydroplaned near the departure end of the runway.
Prior Testing
The aircraft discrepancies were not discovered during antiskid system testing performed about 2 weeks prior to the accident.
