Start Preamble


Federal Aviation Administration (FAA), DOT.




This document makes corrections to the correction to the final rule published in the Federal Register on August 20, 2003 (68 FR 50069). This document makes a minor change to a section number that was changed in the previous correction to the final rule. In the first correction document, we inserted a corrected Parameter 15 into the appendixes for part 121 and part 125 in the final rule. We inadvertently cited § 135.152(j) in the “Seconds per sampling interval” column when we should have cited § 121.344(f).


This correction is effective August 18, 2003.

In response to a series of recommendations issued by the National Transportation Safety Board (NTSB), the FAA revised and updated parts 121, 125 and 135 of Title 14, Code of Federal Regulations (14 CFR) in 1997 to require that flight data recorders on U.S. registered airplanes be upgraded to record additional parameters of data (62 FR 38362, July 17, 1997). The exact number of parameters required depends on the age of the airplane; airplanes manufactured after August 19, 2002, must record 88 parameters of flight data.

The final rule published on July 18, 2003 (68 FR 42932) amends the flight data recorder regulations by expanding the recording specifications of certain data parameters for specified airplanes, and by adding aircraft models to the lists of aircraft excepted from the 1997 regulations. In addition, this rule corrects specifications in an operating rule appendix that were inadvertently omitted in previous actions. These changes are necessary to allow the continued operation of certain aircraft that are unable to meet the existing recorder criteria using installed equipment. The changes are also necessary for certain aircraft for which the cost to retrofit under 1997 regulatory changes would be cost prohibitive.
