   Mechanical throttle linkages went out with the DC3, all modern   
   aircraft since the 1950's have had electrical or electro-mechanical control   
   systems. Early engines so equipped include the Bristol Siddeley   
   Viper designed in 1953   
      
   While not used on commercial aircraft they have indeed caused failures   
   on GA aircraft, an airworthiness directive for the Pt-220C reads   
      
      
   Instances have been reported of throttle quadrants pulling off the fuselage   
   skin to which they were glued and nailed during manufacture. Both front and   
   rear cockpit throttle quadrants must therefore be inspected for looseness   
   immediately and if found loose must be repaired prior to the next flight   
      
      
      
   Think about the problem of running a mechanical control system   
   to the engine hanging on a Boeing 707 pylon. In fact FADEC's   
   have contributed to the far greater reliability of modern engines.
