General aviation (GA) -- a catch-all category that includes about 57% of all civilian aviation activity within the United States -- encompasses a wide range of airports, aircraft, and flight operations. Because GA plays a small but important role in the U.S. economy, improving upon GA security without unduly impeding air commerce or limiting the freedom of movement by air remains a significant challenge. However, policy makers have received mixed signals about the relative security risk posed by GA, due to its diversity and a general lack of detailed information regarding the threat and vulnerability of various GA operations. While some recent high-profile breaches of GA security point to persisting vulnerabilities and limited intelligence information suggests a continued terrorist interest in using GA aircraft, it is evident that GA airports, aircraft, and operations vary significantly with regard to security risk. While the small size and slow speed of most GA aircraft significantly limits the risk they pose, some experts still fear that they could be used as a platform for a chemical, biological, radiological, or nuclear attack. Certain sectors of GA such as crop dusters and larger business aircraft present more specific risks because of their unique capabilities and aircraft characteristics. Because various segments of GA differ significantly in terms of their perceived risk, mitigation strategies should arguably be tailored to some degree based on risk. In step with the premise that security measures should be predicated on assessments of risk, a provision in the FY2006 Department of Homeland Security Appropriations Act (P.L. 109-90) requires the DHS to examine the vulnerability of high-risk sites to possible terrorist attacks using GA aircraft. Based on an analysis of risk, a variety of options exist for mitigating security risks that can be tailored to specific GA airports and operations.
