8 Hydraulic Installation

Ensure all pressure has been bled from the system before disconnecting any lines

or fittings. Hydraulic pressure will exist on the wing tilt circuits unless the wings

are being supported by other means. The hydraulic installation may be performed

with the wings in transport position, resting on the ground or with the tilt cylinders

fully extended.

Component failure due to oil contamination is not covered under the NORAC

UC4.5 system warranty. It is recommended that a qualified technician perform the

hydraulic installation.
