UNSAFE GEAR LIGHT IN CRUISE, GEAR HANDLE UP
Airspeed ...................................................................... MAX 230 KIAS
Spoiler / Speedbrake Lever .............................. VERIFY DISARMED
Caution: If spoiler/speedbrake lever cannot be disarmed, speedbrake
stop and intermediate notches will not be engaged.
Caution should be exercised to ensure lever is not
inadvertently moved to full aft position as this would
permit speedbrakes to full 60. position.
Caution: If damage to landing gear is suspected or if previous gear
malfunction has been indicated, do not recycle gear as this
may cause further damage and make it impossible to
re-extend gear.
ALL HYD PUMPS Switches..................................................... ON, HI
GEAR Handle ........................................................................... DOWN
Move GEAR handle to DOWN and observe gear lights are green and
GEAR DOOR OPEN light is off.

IF Any Gear Light(s) Or GEAR DOOR OPEN Light Is On:
Continue flight without exceeding landing gear extension speed of 300 KIAS / .70 Mach. Leave GEAR handle in UP and operate with both ENG HYD PUMPS switches in HI, TRANS pump switch in ON, and AUX pump switch as required.
Note: Check operation of electrical circuits. Inoperative automatic pressurization, and takeoff warning after flap retraction indicate ground shift mechanism is in ground mode.
