Here's Why Airplanes Have Engines On The Wings Or On The Tail

 

Wing Mount

Pro: Much easier engine access for service, can mount more and/or bigger engines, less structural reinforcing needed, shorter fuel lines, safer in case of engine fire

Con: High noise levels, susceptible to ground/foreign objects/debris damage, requires larger rudder (in case one engine is lost)

Rear Mount

Pro: Quieter operation (from inside cabin), less likely to take in debris/foreign objects, more suitable to more kinds of runways/airstrips, can reverse aircraft on ground
Con: Harder to access for maintenance, requires more structural support and longer fuel lines, more dangerous in case of fire
