The U.S. Federal Aviation Administration (FAA) proposed a $2.75 million civil penalty against Boeing’s commercial airplanes unit for allegedly failing to maintain its quality control system in accordance with approved FAA procedures. In September 2008, Boeing discovered that it had been installing nonconforming fasteners on its model 777 airplanes. The FAA alleged that Boeing repeatedly submitted action plans that set deadlines for the accomplishment of certain corrective actions, but failed to implement those plans until more than two years after Boeing first learned of the problem. In December 2015, Boeing settled this and other pending and potential FAA enforcement cases for $12 million (see Boeing instance, “Settlement of Pending and Potential Enforcement Cases”).
