Flap malfunction detection system

According to an embodiment, a flap malfunction indicator assembly for notifying an observer making a walk-around inspection of an aircraft of a malfunction of one or more connection points coupling a flap assembly to an aircraft wing includes a support mounted to the flap assembly having a perimeter defining an area, an indicator arm pivoted to the support and movable between a first stowed position in which a major portion of the arm is arranged substantially entirely within the area and a second deployed position in which a major portion of the arm is arranged substantially outside the area, a frangible pin or fastener securing the indicator arm to the support in the first stowed position, a trigger element mounted for rotation about a first pivot, an elongated pull linkage coupling the trigger element with a flap assembly, the pull linkage being supported for movement relative to the first pivot to cause rotation of the trigger element when malfunction of a flap assembly occurs, and a spring assembly at the support having one portion exerting a biasing force against a portion of the indicator arm located outside of the area, the spring assembly driving the indicator arm into the second deployed position when the frangible pin or fastener is broken.
