Unsafe Condition
Occurrence of outboard slat skew sensor failure in open or closed position. The combination of an outboard slat skew sensor failed closed, an outboard slat actuator structural failure (rupture), and its adjacent actuator torque limiter failing high (allows higher loads to the panel structure) occurring in the same slat surface, under normal flight loads, may lead to the slat surface detaching from the wing with the possibility of hitting and damaging the horizontal stabilizer and elevator, which may affect the airplane controllability.
