The engine then has a dummy module one (fan) outer air casing installed. It is then winched into the vertical
position and placed and clamped onto a "pot" which is bolted to the floor. On the Adour, the accessory gearbox,
oil tank, engine dressing etc is all removable in one go as a single unit refered to as the pack. In the above pictures
you can see the engine undressed with its dummy module one case installed and clamped verticaly to its pot on the

The first item to be removed following
the pack and various pipes, the bleed
valve, trunions, rear bearing vent tube etc
is the exhaust mixer unit which can be
seen on the left, installed and on the
right sat on the bench
