United Airlines Flight 328, a Boeing 777-200ER, experienced an engine failure and subsequent emergency landing at Denver International Airport (DEN) on February 20, 2021. The incident garnered significant attention, raising questions about aircraft safety and emergency procedures. This comprehensive guide delves into the events leading up to the emergency landing, the response from United Airlines and authorities, and the lessons learned from the incident.
Prior to departure from San Francisco International Airport (SFO), United Airlines Flight 328 underwent a routine pre-flight inspection. No significant issues were identified during this inspection.
During the initial ascent after takeoff, the left engine of the aircraft experienced a catastrophic failure. Witnesses on the ground reported seeing debris falling from the engine. The failure caused substantial damage to the engine casing and surrounding components.
The flight crew immediately followed established emergency procedures. They shut down the failed engine and began descending the aircraft. The pilots declared an emergency and requested immediate priority landing at DEN.
Due to the severity of the engine damage, the flight crew selected Runway 17R at DEN, which is designated for emergencies. Runway 17R is one of the longest runways at DEN, providing ample space for the aircraft to land safely.
Weather conditions at the time of landing were favorable, with clear skies and calm winds. However, there was a small patch of ice on a portion of Runway 17R.
The pilots skillfully maneuvered the aircraft to the designated landing area. Despite the ice patch and high engine thrust from the remaining engine, the aircraft touched down safely on Runway 17R.
Fire and rescue crews were immediately deployed to the scene of the landing. They quickly extinguished a small fire that had ignited in the left engine area. There were no reported injuries among the 241 passengers and 12 crew members on board the aircraft.
Passengers were evacuated from the aircraft using inflatable slides. They were then transported to the terminal for further assistance.
After the evacuation, officials conducted a thorough inspection of the aircraft. The extent of the damage to the left engine and surrounding components was significant.
The National Transportation Safety Board (NTSB) launched an investigation into the incident to determine the cause of the engine failure and to identify any safety issues.
The NTSB released a preliminary report on March 3, 2021, which provided the following key findings:
The NTSB is currently conducting ongoing investigations and is expected to release a final report on the incident in the coming months.
The incident highlighted the importance of rigorous manufacturing standards and quality control in aircraft engine production. The NTSB recommended that engine manufacturers implement additional inspections and testing to prevent similar defects in the future.
The incident also raised questions about the effectiveness of engine monitoring systems. The NTSB recommended that airlines and aircraft manufacturers explore enhancements to these systems to provide earlier detection of potential engine failures.
The successful emergency landing of United Airlines Flight 328 demonstrated the professionalism and skill of the flight crew. The incident reinforced the importance of regular training and adherence to established emergency procedures.
