Background

    This AC focuses on aircraft recording system performance and 
logical recording point locations for storing data communication 
information in onboard crash-survivable memory. Issuance of this AC is 
based in part, on recommendations received from the National 
Transportation Safety Board (NTSB), following investigations of several 
aircraft accidents and incidents. This AC provides guidelines to 
improve the quality and quantity of recorded in-flight information, 
allowing for an increase in the potential for the retention of 
important information needed during accident and incident 
investigations.

How To Obtain Copies

    You can view or download the draft AC from its online location at:
