An engine pylon on a transport aircraft is designed to

  • A.Thrust, weight and inertia loads
  • B.Provide the aerodynamic fairing only
  • C.Carry cabin pressure loads
  • D.Act as the primary wing bending member

Answer: A

The pylon transmits thrust, engine weight and manoeuvre inertia into the wing, and it is designed so that in a severe overload the engine departs cleanly rather than tearing the wing structure. That deliberate weak-link behaviour is a certification consideration in its own right.
