As of Monday, a thief with a taste for avionics apparently is working his (or her) way south along Interstate 95, the ACPI said. Reports began a few weeks ago in the Northeast and the most recent report came last Friday from Freeway Airport in Bowie, Md., near Washington, D.C. Late-model Bendix/King and Garmin units are the preferred choice of thieves overall, and GPS units have become very popular, says the ACPI. Owners of airplanes with that kind of equipment may want to beef up their vigilance or anti-theft protection. The ACPI is a non-profit organization working to reduce aviation-related crime through education and by facilitating cooperation between the aviation industry and law-enforcement agencies. A new Web site is under construction that will help to quickly disseminate information about stolen aircraft and thefts, as well as offering theft-prevention advice.
