OPERATIONAL PROCEDURES
Perform the following steps for unpressurized low-level flight:
Prior to the first flight of the day and before engine and APU start, confirm Ram Air and Dump Valve, or Vent
Valve (Post Mod. 25G726A/C) operative. Ram Air Valve movement can be heard from Rear Equipment Bay
when DUMP VLV , or VENT VALVE (Post Mod. 25G726A/C) is selected OPEN.
1. Configure the aircraft for unpressurized flight:
• Select DUMP VLV, or VENT VALVE (Post Mod. 25G726A/C) fully OPEN.
• F/DK VLV positioned as required.
2. Operate at or below 15,000 feet MSL.
3. Comply with FAR 91.211 or FAR 135.89 and FAR 131.157.
Passenger Oxygen Masks will deploy automatically when the cabin altitude reaches 12,000 feet MSL +/- 500
feet.
The Passenger Supply Valve may be selected closed to prevent passenger oxygen mask deployment,
provided the aircraft is operated at or below 10,000 feet MSL or the passenger cabin has no occupants.

MAINTENANCE
PROCEDURES
Perform the following procedure to bypass the LH and RH Flap Bias Switches:
1.
Ensure power is removed from aircraft.
2.
To bypass LH Wing Flap microswitches:
•
Remove 2nd (from the rear) overwing access panel on LH side, using quick release fasteners.
•
Locate terminal block JBA, remove nut from JBA8, and remove the wire marked A8JB:W1:55:W1:JD3L. Stow wire to safely isolate
the 15/45 Flap LH microswitch.
•
Remove nut from JBA7, and remove the wire marked A7JB:W1:55:W1:P1N from JBA7 and place on JBA8. This isolates the 0
Flap LH microswitch and provides 28V to the SSU 1.
•
Replace nuts on JBA7 and JBA8 terminal blocks and replace overwing access panel.
3. To bypass RH Wing Flap microswitches:
•
Remove 2nd (from the rear) overwing access panel on LH side, using quick release fasteners.
•
Locate terminal block KB, remove nut from KB8, and remove the wire marked 8KB:W2:55:W2:KD4L. Stow wire to safely isolate the
15/45 Flap RH microswitch.
•
• Remove nut from KB7, and remove the wire marked 7KB:W2:55:W2:P2N from KB7 and place on KB8. This isolates the 0 Flap
RH microswitch and provides 28V to the SSU 2.
•
• Replace nuts on KB7 and KB8. terminal blocks and replace overwing access panel.
4. Power up the aircraft and check that the SSU Fault light and the STALL IDENT light are not illuminated.

OPERATIONAL
PROCEDURES
Perform the following steps for unpressurized low-level flight:
Prior to the first flight of the day and before engine and APU start, confirm Ram Air and Dump Valve, or Vent
Valve (Post Mod. 25G726A/C) are operative. Ram Air Valve movement can be heard from Rear Equipment
Bay when DUMP VALVE OPEN is selected.
1. Configure the aircraft for unpressurized flight:
•
Select DUMP VLV, or VENT VALVE (Post Mod. 25G726A/C) fully OPEN.
•
F/DK VLV positioned as required.
2.
Operate at or below 15,000 feet MSL.
3.
Comply with FAR 91.211 or FAR 135.89 and FAR 131.157.
Passenger Oxygen Masks will deploy automatically when the cabin altitude reaches 12,000 feet MSL +/- 500
feet.
The Passenger Supply Valve may be selected closed to prevent passenger oxygen mask deployment,
provided the aircraft is operated at or below 10,000 feet MSL or the passenger cabin has no occupants.
NOTE
Special attention should be given to planning low altitude flights.
