TRANSPORTATION
The engine is transported in metallic container with nitrogen atmosphere. The engine is mounted on a transport stand that serves also as a fixture on which the engine is being prepared for installation in the aircraft. The engine is attached to the transport stand at the reduction gearbox and by the engine mounting ring.
When held in a container, the engine can be transported by any transport means - truck, train, ship or airplane. When transported by air in an aircraft without pressurized cabin (at altitudes above 4,000 m (ISA), it is necessary to loosen the container lid or plugs with the humidity indicator to allow for atmospheric pressure equalization at high altitudes and thus prevent any container damage. However, the nitrogen atmosphere protection would be thus destroyed.
Tools according to the subsection 72.03.01 and accompanying documentation are transported together with the engine. Containers are provided with hoisting eyes.
Metallic container Mass:
Engine on the transport stand ... 225 kg Container with engine, tools, etc. ... 382 kg Container empty, with transport stand ... 165 kg
Metallic container is shown in Fig. 1001, page 1003. Recommended handling is described in subsequent technological instructions.
Working procedure for engine lifting from the container or from the PVC wrapping as well as preparatory work required for shipping the engine to the manufacturer are described in subsequent technological instructions.

Metallic containerMetallic container for the WALTER M601 engine has been manufactured especially for air transportation (in the IL 62, TU 154, L 410 or other types of aircraft). Metallic container is of cylinder configuration with a single-ended cover fastened by lugs. It is provided with inner stiffeners and guide bars that enable an engine on a transport stand to slide in. The stand forms a part of the container and in slid-in position is secured against movement in any direction.
The container is gastight and both its faces are provided with checking plugs for indicators that check moisture content inside the container.
The transport stand serves for convenient handling of the transported engine in dispatch departments as well as for the engine withdrawal from the container at the customer workplace. It is not intended for the transportation of the engine without the container.
The container is equipped with lugs ensuring its stability during transportation. The lugs make possible to stock full containers in stores up to three layers, empty containers in four layers and both full and empty containers in two layers, in any type of transportation. The lugs make also possible horizontal connection of containers into groups as required.
The container provides also for the delivery of a 1 : 1 set of spare parts, tools and parts to accompany the engine.
The container is designed so as to enable its loading by means of a high-lift truck through any of its faces or by a crane using hoisting eyes located on the container upper part.
The container is equipped with an outer closed box for the Engine Log Book insertion. The box can be sealed.
