## Abstract

This action 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.
