CVR Failures and Deficiencies
Trying to put together an informative article for my company's safety news-sheet on the subject of CVR failures (and/or failures to record, failure to stop recording).
In other words I am pursuing instances where investigators, after a serious incident or accident, were denied any useful CVR data due to:
a. System malfunction
b. CB having been pulled (Silkair style)
c. CVR running on and over-writing (either in the air or after landing)
If anybody can point me towards a source of such a compilation or offer up individual cases/instances (preferably with details or a link), or comment generally, it'd be much appreciated.
