Excerpt
Excerpt: On May 28, 1992, the National Transportation Safety Board issued four safety recommendations (A-92-45 through -48) to the Federal Aviation Administration (FAA) concerning fire protection standards for cockpit voice recorders (CVR) and flight data recorders (FDR). The recommendations were prompted by the loss of vital information from several CVRs and FDRs as a result of thermal destruction of the magnetic tape recording media in post impact fires.' The recommendations asked the FAA to cancel Technical Standard Orders (TSO) C51a and C84 (for FDRs and CVRs, respectively), which contain less stringent survivability standards than the current standards in TSOs C123 and C124 (for CVRs and FDRs, respectively) (Safety Recommendation A-92-45), to conduct a study to determine the actual thermal profile of post impact fires and a revised certification test protocol (A-92-46); to revise TSQs C123 and C124 to reflect the results of the study (A-92-47); and to cancel the original (unrevised) editions of C123 and C124 once the TSOs are revised (A-92-48). In its letter to the Board dated August 5, 1992, the FAA agreed with the recommendations and planned to take appropriate actions. On October 6, 1992, the Safety Board classified Safety Recommendations A-92-45 through -48 Open-Acceptable Response. In the interim, the Safety Board has monitored the progress of the FAA's response through staff-level communications and meetings with personnel from FAA headquarters and the FAA Technical Center.
