Background of Alaska Airlines Flight 261
Overview of Alaska Airlines
Alaska Airlines, a well-established carrier in the United States, has a reputation for safety and reliability. However, the events surrounding Alaska Airlines Flight 261 challenged this perception. This flight was a regularly scheduled domestic passenger service from Puerto Vallarta, Mexico, to San Francisco, California, with a planned stopover in Los Angeles.
Flight Details
Flight 261 departed from Puerto Vallarta on January 31, 2000, carrying 83 passengers and five crew members. The McDonnell Douglas MD-83 aircraft, a widely used model at the time, was operated by experienced pilots. However, the flight was destined for disaster, with mechanical failures leading to a catastrophic outcome.
Timeline of the Incident
The sequence of events during Alaska Airlines Flight 261 highlights the rapid progression of mechanical issues and the challenges faced by the crew. Below is a detailed timeline of the incident:
- Approximately one hour into the flight, the crew noticed unusual pitch control problems.
- The aircraft began experiencing severe vibrations, indicating significant structural issues.
- Attempts to regain control were unsuccessful as the horizontal stabilizer failed completely.
- The aircraft plunged into the Pacific Ocean near Point Mugu, California, resulting in the loss of all 88 people on board.
Causes of the Crash
Mechanical Failure
The primary cause of the crash was attributed to a catastrophic failure of the horizontal stabilizer trim jackscrew assembly. The jackscrew, responsible for adjusting the horizontal stabilizer, had experienced excessive wear due to inadequate lubrication over time.
Human Factors
While the mechanical failure was the direct cause, human factors also played a significant role. Inadequate maintenance procedures and insufficient inspection protocols contributed to the failure. The lack of a robust maintenance schedule for the jackscrew assembly was a critical oversight.
Investigation and Findings
The National Transportation Safety Board (NTSB) conducted a thorough investigation into the crash of Alaska Airlines Flight 261. Their findings revealed the following:
