Recommendation Date:11 August 2004
Date Closed:24 February 2017
Ensure that, in addition to the current installation and operating requirements, all CVRs and FDRs are periodically interrogated to ratify the content and quality of the information recorded.
I will not accept this recommendation as the current rule is adequate, in particular Rule Part 21 sets out the requirements. I will however review Convair CVR and FDR modification, installation and maintenance instructions in conjunction with the design data holder to ensure that instructions for continued airworthiness meet rule requirements.
