Engine failure occurs when an engine stops functioning properly, which can happen in various vehicles, including cars, airplanes, and boats. This malfunction can be caused by several factors, such as mechanical issues, lack of fuel, or electrical problems. When an engine fails, it can lead to a loss of power and control, making it crucial for operators to understand how to respond safely. In aviation, engine failure is particularly critical, as it can affect flight safety. Pilots are trained to handle such situations, often relying on backup systems or emergency procedures. Regular maintenance and inspections are essential to minimize the risk of engine failure in any vehicle.
