12
With a turboprop engine the prop would have to be removed
Prior to removal and fitted after the engine is mounted
13

Nacelles and pods are streamlined enclosures used on multi-engine aircraft primarily to
house the engines. They are located below, or at the leading edge of the wing or on the tail of the aircraft.
21
Wing Pylon Mounted Engine (Turbo-fan) The engine is attached to the aircraft pylon by
two mounts, which support the weight of the engine and transmit thrust loads to the aircraft structure
