What is a common cause of engine failure in aircraft?

Fuel starvation or contamination is a common cause of engine failure in aircraft because it directly affects the engine's ability to obtain the necessary fuel flow for combustion. If an aircraft engine does not receive an adequate amount of fuel, or if the fuel is contaminated with water, dirt, or other impurities, it can lead to a lean mixture that may cause the engine to stall. This can result in a loss of power or complete engine failure, which is critical for safe flight operations.

Fuel management is vital in aviation; pilots must ensure that the fuel system is free from obstructions and that the fuel quality meets required standards. Disturbances in fuel supply can arise from clogs in fuel lines, malfunctioning pumps, or even improper refueling practices. Thus, regular maintenance and monitoring of fuel systems is essential to prevent such failures during flight.
