Civil Aviation Authority: Safety Notice. Prevention of the loss of recordings from cockpit voice (CVR) and flight data recorders (FDR).

SAFETY NOTICE, Number: SN–2011/011, Issued: 17 August 2011.

PREVENTION OF THE LOSS OF RECORDINGS FROM COCKPIT VOICE AND FLIGHT DATA RECORDERS

This Safety Notice contains recommendations regarding operational safety.

The Air Accidents Investigation Branch (AAIB) has recently investigated two incidents where the operator failed to preserve recordings from either the Cockpit Voice Recorder (CVR) or Flight Data Recorder (FDR). This prompted them to publish Safety Recommendations 2010-012, 2011-020 and 2011-025. The intent of these recommendations was to bring to the attention of the CAA, AOC operators and associated Continuing Airworthiness Management Organisations (CAMOs) the need to have procedures in place to prevent the loss of such recordings following an occurrence requiring mandatory reporting and to keep a document which presents the information necessary to retrieve and convert the stored data into engineering units.
