The independent inquiry board set up to investigate the first explosive failure said the flight control system failed because of errors in computer software design.
Digital Storm technicians stress-test and benchmark the system via industry standard testing software coupled with a proprietary testing process that detects components which can be prone to future failure.
Saturday's failure was caused by a software malfunction, while the error earlier in the month, which caused the system to shut down for 20 minutes, was caused by incorrect input by an adjoining air traffic control center.
