Unsafe Condition
Service experience has shown that a case of FADEC channel B manifold air pressure (MAP) sensor hose permeability is not always recognized as fault by the FADEC. The MAP value measured by the sensor may be lower than the actual pressure value in the engine manifold, and limits the amount of fuel injected into the combustion chamber and thus the available power of the engine. Additionally, previous software versions allow, under certain conditions and on DA 42 aircraft only, the initiation of a FADEC self test during flight that causes an engine in-flight shutdown.
