A 2020 British Airways Boeing 777 incident at Denver International Airport, where an engine caught fire during takeoff, was caused by pilot error, according to a recently released National Transportation Safety Board (NTSB) report. The investigation revealed the pilots inadvertently applied excessive brake pressure during the initial takeoff roll while attempting to abort due to a perceived anomaly. This mismanaged braking led to extreme heat buildup in the left main landing gear, ultimately igniting a tire and spreading to the adjacent engine.
The NTSB report highlights the crew’s decision-making process and identifies a lack of adherence to standard operating procedures as contributing factors. Specifically, the pilots prematurely rejected the takeoff based on ambiguous airspeed indications, failing to adequately analyze the situation before initiating the abort procedure. The report emphasizes that proper adherence to established protocols, including verifying airspeed discrepancies with other instruments, could have prevented the incident.
Investigators meticulously examined flight data recorders and cockpit voice recorders to reconstruct the sequence of events. The analysis revealed that although one pilot perceived an unusual airspeed indication, the other pilot’s instruments showed normal readings. Despite this conflicting information, the crew opted to abort the takeoff at a relatively high speed. This decision, compounded by the application of excessive braking, resulted in the catastrophic tire failure and subsequent fire.
The NTSB report also addresses the role of training and crew resource management in preventing similar incidents. It underscores the importance of effective communication and coordination within the cockpit, particularly during high-stress situations. The report suggests that airlines should reinforce training programs to emphasize proper decision-making processes, adherence to standard operating procedures, and the effective utilization of all available resources during abnormal events. Furthermore, the investigation touched upon the design and maintenance of braking systems, although the primary cause was attributed to pilot error. The findings serve as a critical reminder of the potential consequences of deviating from established procedures and the crucial role of pilot training in ensuring aviation safety. The incident resulted in significant damage to the aircraft but fortunately, no injuries were reported among the passengers and crew.
