Nose Gear Actuating Cylinder; Removal Of Nose Gear Actuating Cylinder - Piper Lance II Service Manual

LANCE II SERVICE MANUAL
d. Gear "Back-Up" Down and Up:
1. Gear Down: Set power at idle. Glide the aircraft at 113 KIAS. Decrease the
airspeed at the rate of 1 knot per second. The gear should start down between 98 to 108
KIAS. Place the gear selector switch down, after the gear is down and locked.
2. Gear Up: Set maximum climb power. Maintain approximately 70 KIAS for
approximately 15 seconds. Move the gear selector up. The gear should stay down and
locked. Increase the airspeed at the rate of 1 knot per second. The gear should begin to
retract between 76 and 85 KIAS at zero density altitude. The speed at which the gear starts
up will increase 1.3 KIAS for each 1000 feet increase of density altitude.
3. Manual Override Up Latch: With the gear up, the aircraft in normal flight
configuration, select up on the gear override lever. Engage the up latch. The amber up latch
warning light, below the gear selector switch, should be flashing. Gradually slow the aircraft
below the auto gear extend speed and observe that the gear stays fully retracted. Disengage
the up latch. The flashing amber warning light should go out.
e. Gear Indicator Lights:
1. The green lights indicate when the corresponding gear is in the down and
locked position. Turn landing light switch on and off-observe ammeter for indication.
2. The red gear warning light will indicate an unsafe condition. It will indicate
when the gear is in an intermediate position neither fully up nor down. In conjunction with
the gear warning horn, it will indicate when the throttle setting is less than 14 ± 2 inches of
manifold pressure while the gear is not down and locked. It will also indicate when the gear
is down and locked while the selector switch is in the UP position, except at full throttle.
f. The Gear Warning Horn: It will sound in conjunction with red gear unsafe light
per the conditions noted above.
g. Micro Switch Check:
1. The forward throttle micro switch is checked by moving the throttle full
forward while the gear is down and the gear selector switch is in the up position. The horn
should stop sounding and the red light should go out. Retard the throttle slightly and the
horn and light should come on.
2.
The aft throttle micro switch setting is checked as follows: With the gear up,
reduce the throttle at a normal rate. The gear warning horn and the red light should come
on at 14 inches of manifold pressure + 2".
