After months of investigation and extensive research, testing, and analysis, the cause of this accident has never been determined. The Army Safety Center, the CCAD Investigative Analysis Unit, and Boeing continue to monitor and evelauate all CH-47 flight-control anomalies to determine the cause of this accident and take corrective actions.
That entire incident makes uncomfortable reading. And the quote above seems to indicate that they need more incidents/accidents to occur in order to have enough evidence to "take corrective actions". Blinkin' 'eck!
