Japan Air Lines Flight 123

In compliance with standard procedures, JAL retired flight number 123 for their Haneda-Itami routes, changing it to Flight 121 and Flight 127 on September 1, 1985. The Boeing 747SRs were still used on the same route operating with the new flight numbers in the years following the crash until their retirement in 2006, with modern [[Wide-body aircraft|widebody]] aircraft such as the [[Boeing 747-400#747-400D|Boeing 747-400D]] and [[Twinjet|twin-engined]] widebodies such as the [[Boeing 767]] and [[Boeing 777]] replacing them during the 1990s and early 2000s. Boeing 747 operations at JAL ended in 2011 when the last [[Boeing 747-400|747-400]] was returned to the lessor as part of the airline's efforts to cut costs, with the aforementioned twin-engine planes, [[Boeing 787 Dreamliner]], and [[Airbus A350]] operating these routes today.{{citation needed|date=January 2024}}

In 1989, a [[McDonnell Douglas DC-10]] serving [[United Airlines Flight 232]] experienced a similar total loss of hydraulic pressure after suffering an uncontained engine failure while flying over the Midwestern United States. United Airlines check pilot Dennis Fitch, who was aboard Flight 232 as a passenger, had studied the case of Japan Airlines 123 and had practiced similar scenarios in a flight simulator. This experience enabled him to assist the flight crew in making a controlled crash landing at [[Sioux Gateway Airport]] in [[Sioux City, Iowa]], directly contributing to the survival of 184 of the 296 people on board.<ref>{{cite book |last=Gero |first=David |date=1997 |title=Aviation Disasters |location=Yeovil, Somerset |publisher=Patrick Stephens Ltd (Haynes Publishing) |isbn=978-0750931465}}</ref>{{Reference page|page=210}}

This would not be the only time that a 747 crashed due to faulty repair work following a tailstrike. In May 2002, 17 years after Flight 123's crash and 22 years after the accident aircraft's repair, [[China Airlines Flight 611]] from Taipei to Hong Kong with 225 people on board crashed with no survivors when it broke up while cruising at around {{convert|35000|feet}}. Like Flight 123, a doubler plate was not installed based upon Boeing standards.
