H.Amdt.232 - Amendment improves Federal Aviation Administration (FAA) rulemaking activities by requiring the Agency to recognize that the United States aviation industry is composed of a variety of different segments with different operating characteristics and requiring the FAA to tailor regulations to address the unique characteristics of each industry segment. The amendment also requires the FAA to conduct appropriate cost/benefit studies on all proposed regulations and only enact regulations upon a finding that the costs are justified by the benefits.
