Aviation News FAA addresses dual-engine shutdown of A220 P&W engines An airBaltic Airbus A220-300, registered as YL-AAQ, experienced a dual-engine shutdown while landing at Copenhagen Airport (CPH) in July 2021. The FAA investigation found that “the sequence of the auto-throttle increasing throttle to maintain Mach number, immediately followed by pilot command to decrease throttle to idle, caused a transient disagreement between actual and commanded thrust.” This triggered the thrust control malfunction (TCM) detection logic which shut down both engines as soon as wheel sensors detected that the aircraft had physically landed on the runway. The FAA issued an Airworthiness Directive (AD) that requires a FADEC software update.
