Part B Section 12.29
12.29 HYDRAULIC SYSTEM
01 GENERAL
The hydraulic system is a high-pressure accumulator system provided for operation of the
undercarriage and the brakes. The system can be supplied with pressure from:
1) Engine pump
2) Electric pump
3) Hand pump
Normal operating pressure is 800-1000 psi
The system comprises of a hydraulic reservoir, an engine driven pump on the starboard
engine (with back up electric and hand pumps), accumulators, selector valves, a filter and
the necessary hydraulic lines and actuating and latching cylinders. Gauges on the First
Officers instrument panel and in the nose compartment can monitor the pressure within
the system.
02 HYDRAULIC RESERVOIR
The reservoir tank is in the Starboard engine nacelle, outboard, accessed through a lift up
panel secures by fasteners. The tank holds 2 Imperial Gallons of hydraulic oil and the fill
marks are ringed on the dipstick, which is located next to the tank. The fluid level should
be between the top and middle marks when the system pressure is up. It is very easy to
over
Tighten the cap for the reservoir.
03 HYDRAULIC OIL SPECIFICATION
Mineral based (red dyed) fluid Mil H.5606 with total capacity 7 Imp Gals
04 ENGINE DRIVEN HYDRAULIC PUMP
The engine driven pump, mounted on the starboard engine. Will not supply full pressure
below 1500 RPM.
Under normal conditions the pump is idled by a bypass valve, which unloads the system
once, pressure has built up to normal operating pressure of 800- 1000psi. When a service
is employed and the pressure drops below 800 psi the hydraulic pump comes on line and
replenishes the used pressure and oil.
The pump has a safety pressure relief valve, which operates at 1250 psi
05 SYSTEM CAPACITY
The full capacity of the system is 7 Imp gals, with 2 Imp gals being held in the reservoir. A
further supply of hydraulic oil may be kept in the wing cavity just outboard of the reservoir,
together with a funnel for topping up the tank. More usually the container of hydraulic oil is
stored in the Galley Compartment but the funnel remains in the wing next to the reservoir.
