The Federal Aviation Administration (FAA) proposed a $1.55 million civil penalty against FedEx Corp. for allegedly failing to revise its maintenance program for airplane loading containers. FAA alleged FedEx failed to ensure that it used approved standards, inspections, and time limitations for 14 cargo Unit Load Devices (ULDs) used on the company’s airplanes beginning in early 2008. The civil penalty addressed 124 flights from March 20 to April 17, 2008. Aircraft ULDs are containers used to load freight. FAA also claims FedEx was notified of the problem in March 2008 but did not fix it until almost a month later.
