Federal Aviation Administration (FAA), DOT.


Final rule; disposition of comments.


On December 31, 2012, the FAA published a final rule with a request for comments amending the operating regulations for flight data recorders by correcting errors in recording rates in three different appendices. These errors created requirements that could not be met by certain airplanes without extensive modification, which was not intended when the requirements were adopted. The corrected recording rates are as intended when the applicable flight data recorder parameter requirements were adopted, but which had been omitted from the then current publication of the regulatory text.


January 13, 2014.

The final rule amended three appendices in 14 CFR related to flight data recorder (FDR) requirements:

  • First, Appendix E to part 91 was amended to correct a typographical error introduced when the rule was published. For the altitude parameter, the sampling rate per second was listed as 11. The correct rate had always been 1 sample per second.
  • The second and third corrections concerned identical standards in Appendix M to part 121 and Appendix E to part 125. When footnote 5 was added in 1999 to each Appendix, the sampling interval was left off for certain airplanes. The correction put the sampling interval of once per second back in the footnote for the affected airplanes.

None of these changes required action by airplane owners, operators or manufacturers as the affected airplanes already complied with the requirements of the originally adopted rules and the corrections adopted. Since these requirements were intended in the original rules, there was no new impact on safety.

Discussion of Comments

The FAA received no comments on the final rule.


Since no comments were submitted in response to the final rule, the FAA has determined that no revisions to the rule are warranted.
