The Investigation: Uncovering the Truth

The National Transportation Safety Board (NTSB) launched an immediate and thorough investigation into the crash of Alaska Airlines Flight 261. The investigation involved the meticulous examination of the wreckage recovered from the ocean floor, as well as a review of the aircraft's maintenance records, flight data recorder (FDR), and cockpit voice recorder (CVR). The NTSB investigators faced a challenging task due to the extent of the damage to the aircraft and the underwater conditions. However, they were able to piece together a detailed account of the events leading up to the crash. The investigation focused on the horizontal stabilizer jackscrew assembly, a critical component responsible for controlling the stabilizer's movement. The jackscrew is a threaded rod that moves the horizontal stabilizer up and down, allowing the pilots to adjust the aircraft's pitch. The investigation revealed that the jackscrew was severely worn due to inadequate lubrication and maintenance. This wear led to excessive play in the assembly, making it difficult for the pilots to control the stabilizer. The NTSB's investigation also uncovered systemic issues within Alaska Airlines' maintenance program, including failures to properly inspect and lubricate the jackscrew assembly. The investigation was a complex and time-consuming process, but it ultimately provided critical insights into the causes of the crash and led to important safety recommendations.

The Jackscrew Assembly: A Critical Failure

The investigation into the crash of Alaska Airlines Flight 261 revealed that the primary cause of the accident was the failure of the horizontal stabilizer jackscrew assembly. The jackscrew is a critical component that translates the rotation of a motor into linear motion, which in turn moves the horizontal stabilizer. This movement allows the pilots to control the pitch of the aircraft, which is essential for maintaining stable flight. The NTSB's investigation found that the jackscrew on Flight 261 was severely worn due to insufficient lubrication. Over time, the lack of lubrication caused the threads of the jackscrew to wear down, creating excessive play in the assembly. This play made it increasingly difficult for the pilots to control the horizontal stabilizer, eventually leading to a complete loss of control. The investigation also revealed that Alaska Airlines had extended the intervals between jackscrew inspections, which further contributed to the problem. The combination of inadequate lubrication and extended inspection intervals created a dangerous situation that ultimately led to the crash. The failure of the jackscrew assembly was a direct result of maintenance deficiencies and systemic issues within Alaska Airlines' maintenance program. This critical failure underscores the importance of proper maintenance and the need for strict adherence to safety protocols.

Systemic Failures and Maintenance Deficiencies

The crash of Alaska Airlines Flight 261 exposed significant systemic failures and maintenance deficiencies within Alaska Airlines' operations.
