Rudder Action, Wake Turbulence Still Figure In USAir 737 Crash Probe
Rudder action and wake turbulence still are being investigated as possible causes of the September 1994 crash of a USAir 737-300 near Pittsburgh, the National Transportation Safety Board's unusual second public hearing into the crash was told yesterday in Springfield, Va. Board investigator Thomas Haueter said the 737 experienced a yawing or change of direction just before it went into a roll and crashed, killing all 132 aboard. Possible causes of the yaw are malfunctioning of the rudder cable, wake turbulence, an electrical problem or pilot action, he said.
