An apparatus and method for suppressing dynamic instability in a bleed duct (42) of a gas turbine engine (10) includes a fan bypass duct (32) configured to permit a flow of air (28) through the gas turbine engine (10). The fan bypass duct (42) defines a fan duct surface (31), and the bleed duct (42) has an inlet (41) in fluid communication with the fan bypass duct (32) and a flow control valve (44) having an opened position and a closed position. A flow diverter (50) is positioned on the fan duct surface (31) proximate the inlet (41) of the bleed duct (42) and diverts the flow of air (28) from the inlet (41) when the flow control valve (44) is closed, while permitting a portion (57) of the flow of air (28) to enter the inlet (41) when the flow control valve (44) is opened.
