Place flaps in "retracted" position and have a helper hold the left flaperon trailing edge in line
with tip trailing edge (in trail) position.
Verify right flaperon trailing edge is 1/4 inch [6.3mm] to 1/2 inch [12.6 mm] below trail
position.
Verify that when a 10lb [4.5kg] upward load is applied to the trailing edge of the right flaperon,
the trailing edge does not flex above trail position more than 1/2 inch [12.6 mm].
Move stick full aft and hold against the aft stop while moving the stick left stop-to-right stop.
Verify smooth operation, no interference or binding, and a minimum of 1/8 inch [3.17mm] gap
between each flaperon (top and bottom skins) and the fuselage skin when the flaperon is
deflected to its highest trailing edge up position. If the flaperon gap is below minimum, mark
the trim line for proper gap and use aluminum shears and a file to trim the excess.
Move stick full forward and hold against the forward stop while moving the stick left stop-to-
right stop.
Verify smooth operation, no interference or binding, and a minimum of 1/8 inch [3.17mm] gap
between the flaperon and the fuselage skin when the flaperon is deflected to its highest up

excess.
Place flaps in "50%" position.
Move stick full aft and hold against the aft stop while moving the stick left stop-to-right stop.
Verify smooth operation, no interference or binding.
Move stick full forward and hold against the forward stop while moving the stick from left stop-
to-right stop. Verify smooth operation, no interference or binding.
Place flaps in "full" position.
Move stick full aft and hold against the aft stop while moving the stick from left stop-to-right

Move stick full forward and hold against the forward stop while moving the stick from left stop-
to-right stop. Verify smooth operation, no interference or binding.
