Shutdown Procedures
Start the Shutdown Procedures after aircraft comes to a complete stop.
PARKING BRAKE ................................................................. Set (C)
Verify warning light is illuminated.
Check Electrical Power.
Engine start levers...............................................................Cutoff (C)
Operate the engines at or near idle thrust for a minimum of three
minutes before shutdown to thermally stabilize the engines and
reduce undercowl soak-back temperatures. This time period is a
recommendation, not an engine limitation.
Note:
if idle reverse thrust is used during the landing rollout the
cooldown time should be of two and a half minutes.
Routine cooldown times of less than three minutes or less than two
and a half minutes (after an idle reverse landing) before engine
shutdown can cause engine degradation.
If APU is not available shut down ENG No. 2 and after Ground
Power is available and on bus shut down ENG No.1.
Fuel Panel ...........................................................................Check (C)
Note:
check SPAR VALVE Closed light. It illuminates bright when
fuel control switches or engine start levers are moved to
cutoff and remains illuminated DIM with engines shut
down.
FASTEN BELTS switch ................................................... OFF (F/O)
Set immediately after the engines are shutdown.
ANTI COLISION LIGHT switch...................................... OFF (F/O)
Set immediately after the Fasten Belts switch is placed OFF.
PARKING BRAKE ................................................................. Set (C)
Release the Parking Brake only after Ground Staff confirms the
airplane is on chocks. Release the brakes smoothly to prevent
unwanted aircraft movement. Make sure the aircraft does not
move after parking brake is released.
