2.3 MAINTENANCE PRACTICES FOR AIRCRAFT EQUIPPED WITH WIPAIRE
2100 A AMPHIBIOUS FLOATS
2.3.1 PREPARATION
a. Remove any items not listed on the Aircraft Equipment List (such as rags, charts,
tools, etc.) The Aircraft Equipment List is found in Section 6 of the Pilot's
Operating Handbook and Aircraft Flight Manual.
b. Clean the aircraft to remove excess dirt and grease.
c. Remove the fuel from the aircraft. This may be accomplished by opening the fuel
drains until all remaining fuel is drained.
d. Check that the oil is full (8 quarts on the dip stick).
e. Position the pilot's seat in the mid position.
f. Zero the scales or record the tare, as appropriate.

2.3.2 WEIGHING THE AIRCRAFT

a. Place the aircraft on calibrated scales. The range of the scales should be 1000
lb. for each main wheel.
b. Level the aircraft (Refer to Section 08-00-11.2).
c. Measure the arm for the front and rear wheels. This is to be done by dropping a
plumb bob off the left and right extremes of the leading edge of the forward float
spreader bar and marking these locations on the floor. Draw a line on the floor
between these points. Then, measure the longitudinal distance from each of the
front and rear wheels to the line. The leading edge of the forward spreader bar is
located at FS 40.1 (Figure 08-00-8). Record this information in Figure 08-00-6.
The Left and Right front wheel measurements of the floats will be a negative number
d. Record the weight of all four wheels in Figure 08-00-7.
