A mechanical amplifier is provided for use in a failure correction control system in which the amplifier receives two mechanical input signals during failure-free operation of the control system, and combines these signals to produce an output. The amplifier includes two mechanical channels which can comprise a series of pivotally connected links. Each channel includes an input element that receives a separate input signal and transmits this signal to an output member. Gain control means are connected to each channel to restore a full range of movement to the output member if one of the input signals is jammed. The gain control means increase the length of the output moment arm in the nonfailed channel. This increased moment arm increases the distance the nonfailed channel can move the output member and offsets the effect of the failed channel. The amplifier also includes disconnect failure accommodation means for maintaining a full range of output after a disconnect failure in the linkage supplying one input signal, or in one channel of the amplifier.
