The NTSB last month issued a scathing report highly critical of the FAA and the transport-helicopter industry for not embracing flight data recorders (FDRs). The Safety Board criticized the FAA for its lack of enforcement of Part 135 helicopter FDR requirements, the wording of those requirements that enable operators to avoid compliance by removing seats and for granting numerous requests for exemptions from helicopter operators. The NTSB has asked the FAA to require all Part 91 and 135 transport helicopters to be equipped with a cockpit voice recorder  and an FDR.
