Flight Crew Overcame Equipment Problem
Aircraft; Human Factors; Weather
While in cruise flight the right engine was inadvertently shut down when a window shade fell onto the right engine fuel control during light turbulence. The flight crew took immediate action and slightly decreased pitch to account for decreasing airspeed. The crew was aware of what caused the engine to shut down and corrected the problem by returning the fuel control to the run position. The engine spooled back to cruise power and the aircraft was returned to the assigned altitude of FL390. Altitude loss was estimated to be no more than 300 feet. The event did not cause a response from ATC. The crew evaluated the matter; called company operations control; explained the event and continued on to destination.
No engine or airframe limits were approached or exceeded during the event.
When a windshield sun visor fell from its hanger on a B767-300ER in cruise at FL390 it struck the right engine fuel control; causing it to move to the cutoff position and shutting down the engine.  The flight crew promptly returned it to the run position and the engine restarted.  A loss of 300 feet during the episode went unnoted by ATC and the flight continued to destination.
