The FAA proposes an airworthiness directive for the Cessna 750 Citation X prompted by reports of direct current (DC) generator overvoltage events. The generator control unit (GCU) overvoltage protection circuit can become damaged and allow high voltage to pass through to the airplane systems and electrical components, which, if not corrected, could result in smoke in the cockpit and loss of avionics and electrical systems.

The Nor’Easter that tore through the Northeast over the weekend caused flooding damage and power outages throughout the region and spurred New Jersey to declare a state of emergency. At Teterboro (N.J.) Airport, wind gusts of nearly 60 miles per hour were reported, knocking out power to the control tower and remote antenna transmitters around 6 p.m. Saturday, resulting in an immediate switch to back-up batteries.

Fortunately, it was a clear, sunny day (rather than the proverbial dark, stormy night) over the Northeast when the electrical power gridwork gave up the ghost at 4:11 p.m. on August 14. Though 9/11 jitters surfaced, initial fears of terrorism were quickly calmed. U.S. and Canadian power providers were pointing fingers at each other long before most affected areas had their lights back on.
