MAINTENANCE MANUAL EXTRA 330LX
O 12 Check for minimum 3.5 mm (1/8") clearance of rudder
pedal versus safety stop when fully deflected for rudder
cables having 50 h flight time minimum. On newly installed
rudder cables the minimum spacing is 6 mm (1/4"). This
check is to be performed with zero loading on the rudder
pedals.
O 13 Rough check of safety stop clearance. With a force of
approx. 90 kg (200 lbs) acting on the fully deflected rudder
pedal the safety stop shall not be reached. If the stop is
reached the control system indicates too much flexibility
which needs to be traced. In this case contact EXTRA
Flugzeugproduktions- und Vertriebs- GmbH for advice.
O O 14 Inspect all flight control surface ventilation holes for ob-
struction.
O 15 Inspect elevator balance weights for looseness, clearance,
condition and interference with the composite structure.
O 16 Visually inspect metal push/pull control rods for corrosion,
loose or popped rivets, cracks, or other visible damage,
especially at their end fittings. In case of suspected cracks,
remove push/pull control rod, strip the paint in the sus-
pected area and carry out a detailed inspection using a
magnifying glass (x10). Replace the related control rod in
case a crack is found otherwise reapply surface treatment
and reinstall push/pull control rod.
O 17 Visually inspect fiber composite push/pull control rods for
cracks, impacts or other visible damage, especially at their
end fittings. No gap between aluminum head and rod is
allowed. Contact the manufacturer in case a gap is detected.
