CONTROL SYSTEM
♦ Check that canopy sponge seals are in place and that the
canopy locking handle is adjusted so it must be forced hard
forward to lock. This is extremely important to eliminate any
possibility of it being bumped open in flight.
♦ Check elevator and aileron pushrods for proper installation
(spacers, washers, bolts, locknuts, clevis pins, and safety
clips installed properly)
♦ Check elevator and aileron pushrods for freedom of
movement through-out control travel.
♦ Check elevator and aileron for freedom of movement
throughout range without binding or chafing.
♦ Check pitch and roll trim mechanisms for proper function,
and freedom of movement.
♦ Check rudder pedals for freedom of movement, cable
attachment, and positive return to neutral
♦ Check rudder pulleys for free rotation and cable guard
installation (the eight cotter pins through the pulley
brackets).
♦ Check rudder cable clearance throughout control travel.
♦ Check brake actuating mechanism for freedom.
♦ Check all rod ends. Reject any with evidence of bent tangs.
♦ Check elevators for proper mass balance. They should
hang 12 to 25 degrees nose down when suspended from
the hinge pin by a fine wire. Weight should be evenly
distributed between inboard and outboard locations.
Maximum elevator weight with mass balances installed is
3.9 Ibs. left and 3.6 lbs. right . Check this.
♦ Check ailerons for proper mass balance. When suspended
from the hinge pivots, the ailerons must hang between the
angle that makes the bottom surface level and the angle
that makes the top surface level (after painting).
♦ Check for 1/16" minimum clearances around all mass
balances. Binding can occur at elevated load factors if the
clearance is too tight.
