SECTION 2 - AIRCRAFT SYSTEMS D. HYDRAULIC Aircraft Ground Training:

Section 2 - Aircraft Systems Hydraulic Brake System  The brake system is the only hydraulically activated system on the PA  The Brakes are operated by toe pedals attached to the left rudder pedals or by a hand lever and master cylinder located below and behind the left center of the instrument sub-panel.  Hydraulic cylinders are located above each pedal and adjacent to the hand lever.  The brake fluid reservoir is on the top left front of the fire wall.

SECTION 2 - AIRCRAFT SYSTEMS D. FUEL Aircraft Ground Training:

Section 2 - Aircraft Systems E. Fuel 1) Fuel tanks 2) Pumps (engine driven and boost pumps) 3) Valves 4) Fuel system schematic 5) Quantity indicators

Aircraft Ground Training: Section 2 - Aircraft Systems Fuel The fuel system consists of two aluminum tanks contained in the inboard leading edge section of the wings plus two fiberglass tanks, one located in each wing tip.  Main Tank Capacity = 25 U.S. gallons  Tip Tank Capacity = 17 U.S. gallons Fuel Grade = 100 LL Avgas

Aircraft Ground Training: Section 2 - Aircraft Systems Fuel System Schematic

Aircraft Ground Training: Section 2 - Aircraft Systems Fuel Fuel is taken from each tank through a screen located in the tank outlet fitting and onto a combination fuel selector valve and strainer located under the floor panel under the middle seats.

Aircraft Ground Training: Section 2 - Aircraft Systems Fuel Selector Valve

Aircraft Ground Training: Section 2 - Aircraft Systems Fuel The fuel selector valve is controlled remotely by a selector lever located on the sloping face of the control tunnel. The strainer portion of the valve is operated by a lever located on the right front side of the spar cover under the forward end of the right middle seat. From the selector valve, fuel is drawn through the electric fuel pump(s) located in the area under the middle seats, through the engine driven pump and onto the injector.

Aircraft Ground Training: Section 2 - Aircraft Systems Fuel Four electric fuel quantity gauges are mounted in the instrument cluster located on the right side of the instrument panel. Each gauge is connected to a sender unit installed in the fuel tanks.

SECTION 2 - AIRCRAFT SYSTEMS D. AIR CONDITIONING Aircraft Ground Training:

Section 2 - Aircraft Systems F. Air Conditioning 1) Heaters 2) Fans 3) Environmental control devices

Aircraft Ground Training: Section 2 - Aircraft Systems Air Conditioning The air conditioning system is a recirculating, independent air system. Major components include:  Evaporator  Condenser  Compressor  Blower  Switches  Temperature Controls Evaporator, located behind the rear baggage compartment, cools the air.

Aircraft Ground Training: Section 2 - Aircraft Systems Air Conditioning Condenser  Mounted on a retractable scoop on the bottom of the fuselage.  The scoop extends when the system is ON and retracts flush to the fuselage when the system is OFF. Compressor  Mounted on the forward right underside of the engine.  Electric clutch automatically engages or disengages the compressor to the belt drive system.

Aircraft Ground Training: Section 2 - Aircraft Systems Air Conditioning Controls mounted on right side of instrument panel.  Fan can be operated independently of A/C, but must be ON for A/C operation.  Cooling air should be felt within one minute after A/C is turned ON. Condenser door light is located to the right of the engine instrument cluster. Light illuminates when the door is open and is off when door is closed.

Aircraft Ground Training: Section 2 - Aircraft Systems Air Conditioning Whenever the throttle is in the full forward position a micro-switch disengages the compressor and retracts scoop allowing for maximum power and rate of climb. When the throttle is retarded approx ¼” from full forward, the clutch with engage, scoop extend, and system will again supply cool air. Recommended to turn off A/C prior to takeoff. Always remember to shutoff A/C and ensure scoop is fully retracted prior to engine shutdown.

Air Conditioning System Schematic

Aircraft Ground Training: Section 2 - Aircraft Systems Air Conditioning (heating and ventilating system) Heat for the cabin interior and defroster comes from a heater muff attached to the exhaust system. Controls are located on the lower right side of the instrument panel. Fresh air inlets are located in the leading edge of each wing and in the fin. Two adjustable outlets are located on each side of the cabin (forward and aft of front seat near floor) Adjustable outlets also on cabin ceiling above each seat.
