Final Rule - Request for Comment

Digital Flight Data Recorder

This regulation allows operators of specified airplanes to operate those airplanes under part 121, part 125, or part 135 without meeting the resolution requirements for certain parameters of information recorded by flight data recorders. Shortly before the compliance date for the regulations, the FAA received information from airplane manufacturers that certain airplane models in service did not meet the resolution requirements. This regulation is needed to allow operators of these airplanes to continue operating these airplanes with their current recording capabilities until the FAA is able to determine the appropriate remedy for this problem. Dates: Effective: August 17, 2001. Submit comments by September 21, 2001.

Comments of National Transportation Safety Board

Digital Flight Data Recorder

The Safety Board has reviewed Special Federal Aviation Regulation (SFAR) No. 89 "Digital Flight Data Recorder [DFDR] Resolution Requirements" dated August 22, 2001, and concurs with the intent of the regulatory change to provide temporary relief to the operators of specified airplanes from the FDR resolution requirements of appendix M for certain parameters.

Because this SFAR was the direct result of a petition for exemption from the Boe:ing Company (Boeing), the Safety Board believes that its comments would be most effective if specifically directed toward the Boeing petition. To that end, the Safety Board requested and received a copy of the May 22, 2001, letter from Boeing to the Federal Aviation Administration (FAA) Office of Rulemaking that requested the exemption from FAR 121.344, appendix M resolution requirements for certain parameters on some Boeing airplane models. In reviewing this letter, the Safety Board found a number of exemption requests, regulation updates, and position statements that go beyond what is addressed by this SFAR. The Safety Board believes that some of the positions and opinions expressed in that letter could significantly influence subsequent DFDR rulemaking. Therefore, the Safety Board offers the following comments to the May 22, 2001, letter from Boeing that requests an exemption from FAR 121.344, appendix M resolution requirements.
