During the 1990s, a series of [[Boeing 737 rudder issues|rudder issues]] on series -200 and -300 aircraft resulted in multiple incidents. In two total loss accidents, [[United Airlines Flight 585]] (a -200 series) and [[USAir Flight 427]], (a -300), the pilots lost control of the aircraft following a sudden and unexpected deflection of the [[rudder]], killing everyone aboard, a total of 157 people.<ref>{{Cite news|url=https://news.google.com/newspapers?nid=1842&dat=19990912&id=LIUfAAAAIBAJ&sjid=bckEAAAAIBAJ&pg=3456,2004004|title=Report says Boeing 737 rudder problems linger|date=September 12, 1999|newspaper=[[TimesDaily]]|access-date=July 10, 2016|archive-date=October 7, 2018|archive-url=https://web.archive.org/web/20181007121023/https://news.google.com/newspapers?nid=1842&dat=19990912&id=LIUfAAAAIBAJ&sjid=bckEAAAAIBAJ&pg=3456,2004004|url-status=live}}</ref> Similar rudder issues led to a temporary loss of control on at least five other 737 flights before the problem was ultimately identified. The [[National Transportation Safety Board]] determined that the accidents and incidents were the result of a design flaw that could result in an uncommanded movement of the aircraft's rudder.<ref name="AAR01-01 (UA Flight 585 Amended) Final Report">{{cite book |url=https://www.ntsb.gov/investigations/AccidentReports/Reports/AAR0101.pdf |title=Uncontrolled Descent and Collision With Terrain, United Airlines Flight 585, Boeing 737-200, N999UA, 4 Miles South of Colorado Springs Municipal Airport, Colorado Springs, Colorado, March 3, 1991 |publisher=[[National Transportation Safety Board]] |id=NTSB/AAR-01-01 |date=March 27, 2001 |access-date=January 17, 2016 |archive-date=October 2, 2015 |archive-url=https://web.archive.org/web/20151002041524/http://www.ntsb.gov/investigations/AccidentReports/Reports/AAR0101.pdf |url-status=live}}</ref>{{rp|13}}<ref name="NTSB AAR-99-01 (USAir Flight 427) Final Report">{{cite book |date=March 24, 1999 |publisher=[[National Transportation Safety Board]] |url=https://www.ntsb.gov/investigations/AccidentReports/Reports/AAR9901.pdf |title=Aircraft Accident Report – Uncontrolled Descent and Collision With Terrain, USAir Flight 427, Boeing 737-300, N513AU, Near Aliquippa, Pennsylvania, September 8, 1994 |id=NTSB/AAR-99-01 |access-date=July 10, 2016 |archive-date=October 14, 2012 |archive-url=https://web.archive.org/web/20121014045026/http://www.ntsb.gov/doclib/reports/1999/AAR9901.pdf |url-status=live}}</ref>{{rp|ix}} As a result of the NTSB's findings, the [[Federal Aviation Administration]] ordered that the rudder servo valves be replaced on all 737s and mandated new training protocols for pilots to handle an unexpected movement of control surfaces.<ref>{{Cite web|url=http://www1.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAD.nsf/WebNewAD/2A37F5FABA444A8086256C4B005A2884?OpenDocument|title=Boeing Model 737 Series Airplanes|website=www1.airweb.faa.gov|access-date=May 21, 2016|archive-url=https://web.archive.org/web/20181007121005/http://www1.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAD.nsf/WebNewAD/2A37F5FABA444A8086256C4B005A2884?OpenDocument|archive-date=October 7, 2018|url-status=dead}}</ref>
