Boeing rudder issues in the 1990s? How about the 2010s? A KC-135R(Boeing 707 variant) in 2013 crashed of the same issues as the article.[1] The KC-135R is essentially a modified 707 retooled with 737 engines and a beefed up vertical stabilizer to account for the increased power of the engines. This modification of the KC-135R occurred in the 90s and has been plagued with rudder problems ever since. The accident in 2013 was attributed to pilot error, because there are procedures to turn off the PCU if the rudder goes haywire... but why not just fix the problem outright?
