The goal of this National Transportation Safety Board study was to better understand the risk factors associated with accidents that occur in weather conditions characterized by IMC or poor visibility ("weather-related accidents"). The study accomplished this goal using the case control methodology, which compared a group of accident flights to a matching group of nonaccident flights to identify patterns of variables that distinguished the two groups from each other. This methodology expands on previous Safety Board efforts that have typically concentrated on summaries of accident cases. For this study, Safety Board air safety investigators (ASI) collected data from 72 GA accidents that occurred between August 2003 and April 2004.

The primary goal of this project is to learn more about the housing conditions of the rural elderly in Illinois. By using questions similar to those included in the American Housing Survey (AHS) used by the Bureau of the Census, comparisons can be made between Illinois residents and a national sample. The questions used in this Housing Conditions and Housing Options for Older Residents Survey (2002) (Appendix B) focus specifically on issues related to the availability and condition of plumbing, heating, electricity, and upkeep using guidelines extablished by the AHS. ... There are three objectives for this study (1) to determine the type and condition of housing occupied by older residents in three regions of Illinois, (2) to determine the types of housing elderly residents would choose from a list of options and what conditions would cause them to choose that type of housing, and (3) to examine whether regional variations exist in housing conditions and housing options among rural residents of Illinois.
