The paint hangar of the glorious C27J aircraft also had to accommodate maintenance programmes of military aircraft, which, due to their small size, would have occupied only part of the existing paint hangar. It was therefore necessary to create a mobile partialisation, consisting of motorised bulkheads for the part at constant height and motorised roll-up curtains for the upper part (vertical stabiliser); naturally, the aeraulic circuits were modified for the relative partialisation.
