"In 1994, a US Air Boeing 737 crashed in Pittsburgh, Pennsylvania, killing 132 people. Three years earlier, a United Airlines Boeing 737 crashed in Colorado Springs, Colorado, killing 25 people. Investigators blamed both crashes on problems in the planes' rudder control system, leading the FAA to demand regular checks of the 737's rudder system."
The checks in question were not even remotely related to the rudder PCU issue. They were about skin cracks, checks that became required after an Aloha 737 became the first ever cabriolet model in Boeing's line.
