airspeed envelope in increments of not more than 5 knots. At
each increment, access the damping of the controls as follows:
Kick a rudder pedal, and jab the stick left, right, forward, and aft.
After each input, the controls should immediately return to trim,
and any structural motion should damp within one cycle. This
will require at least 3 or 4 dives, climbing back to altitude
between dives. Do not expand airspeed in the dive when below
7,000 ft. AGL. Use care to not over speed the engine RPM. If
you have just increased speed and find lower damping (i.e., the
structure or controls shake more after the jab than at the 5-knot
lower speed), do not continue to higher speeds. Recheck
balance and weights of control surfaces. Solve any suspected
cause of low damping before expanding airspeed. Expand
speed to at least the red-line speed you desire to place on your
aircraft, up to, but not exceeding 190 knots (220 mph) IAS.
Placard your airspeed indicator with your red line.
CAUTION
Friction in the pitch system can seriously degrade flying qualities.
