| Abstract: | P2 engine split faults on C J 1＋ aircraft in CAFUC happen several times. The authors analyze the operating principle of the system based on one P2 split fault incident and conclude the cause： it will trigger the P2 engine split fault message when the mean value differential of inlet total pressure exceeds 0.5 psi between left engine and right engine. This article proposes some beneficial suggestions to pilots and maintenance staff on dealing with the fault to decrease the rate of incident. |
