This refers to a specific incident involving United Airlines Flight 1712, piloted by Captain Terri Owens, on December 27, 1997. Experiencing severe oscillations during its descent into Portland International Airport, the aircraft narrowly avoided a catastrophic crash. This event prompted significant investigations by the National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA).
The incident’s importance lies in its contribution to aviation safety improvements. The ensuing investigations revealed critical issues related to pilot training, aircraft design (specifically the Boeing 747-400’s horizontal stabilizer system), and emergency response protocols. The lessons learned directly influenced changes in pilot training procedures regarding unusual attitude recovery, improved aircraft maintenance practices, and enhanced understanding of aerodynamic phenomena. This event stands as a critical case study in aviation safety training programs worldwide.
