@aircrashbriefs: USAir Flight 427 was a scheduled flight from Chicago O’Hare to Pittsburgh on September 8, 1994. 🔻 What happened: • The aircraft was a Boeing 737-300. • While approaching Pittsburgh International Airport, the plane suddenly rolled uncontrollably to the left. • The pilots tried to recover but within seconds the jet went into a steep dive. • It crashed in Hopewell Township, Pennsylvania, killing all 132 people on board. 🔻 Cause: The NTSB concluded after a long investigation that the crash was caused by a rudder malfunction. The rudder unexpectedly moved in the opposite direction of the pilots’ command, a known design flaw in Boeing 737s at the time. This accident, along with United Flight 585 (1991) and Eastwind Flight 517 (1996), led to major changes in 737 rudder systems and pilot training. #Flight427 #PlaneCrash #AviationDisaster #USAir #aviation
