ALIGNMENT OF NOSE LANDING GEAR.
1. Place the airplane on a smooth level floor that will accommodate the striking of a chalk line.
2. Ascertain that the nose gear is properly adjusted.
3. With the landing gear in the down-locked position, weight proportionally on the nose gear and the
nose wheel facing forward, adjust the steering bellcrank. The bellcrank is attached at the lower front of the
engine mount directly aft of the gear housing and may be adjusted by loosening its attachment bolt and sliding
the bellcrank fore and aft until it clears each steering arm rollers by .03 of an inch. Retighten the attachment
bolt.
4. Place the airplane on jacks. (Refer to Jacking, Chapter 7.)
5. Level the airplane laterally and longitudinally. (Refer to Leveling, Chapter 8.)
6. From the center point of the tail skid, extend a plumb bob and mark the contact point on the floor.
7. Extend a chalk line from the mark on the floor below the tail skid to a point approximately three feet
forward of the nose wheel. Allow the line to pass under the wheel at the center line of the tire. Snap the chalk
line.
8. Clamp the rudder pedals to align them in a lateral position. Ascertain that the rudder pedals are in their
neutral position. (Refer to Figure 32-9.)
9. Adjust the rod end bearings of each steering control rod to align the nose wheel with the chalk line and
to bring the rudder pedals into neutral angle fore and aft.
10. Install the steering push rods on the pilot's rudder pedals. Adjust the rods so the lengths are both the
same and the rudder pedals are at their neutral position.
11. To align the nose wheel straight forward, stand in front of the nose gear and align the center rib of the
tire with the chalk line, or lay a straight edge along the side of the tire and parallel the straight edge with the
chalk line.
12. Install the nose wheel bungees in their neutral position (no load on the bungee springs). Adjust bungee
rod ends as necessary.
13. Place a bubble protractor against a rudder pedal steering tube to check the neutral angle as shown in
Figure 32-9.
