There are many causes of provider aborts. One signficant contributor is known as 'VDR Deafness' which affects Rockwell Collins VDRs and accounts for approximately 50% of the PAs seen currently. A fix for the problem is now available and known to work, so in order to find other causes of provider aborts it has been decided to investigate PAs that occur in aircraft that are fitted with the fix for VDR deafness. These aircraft of special interest are being closely monitored and any PAs investigated.
The following aircraft are known to have the version of the Rockwell Collins VDR that includes a fix for the VDR deafness problem from at least the dates given (and possibly before):
