In case of canopy misting, open air vents and windows to ensure proper ventilation. If the
situation cannot be corrected or occurs suddenly, such as after a bird strike or canopy icing,
maintain safe attitude by visual reference to the sides, using the open sliding window, if
necessary.
When at safe height, stabilize the aircraft at 90 km/h and clear the viewing obstruction by
using a hand through the sliding window or from the inside.
If forward vision is still impaired or lost, continue flight in a side slip, using the open sliding
window for visual reference. Land at the nearest suitable location and align just prior to
touch-down.
3.17 Rotor Icing
A more than normal or constantly increasing power demand may be caused by an iced-up
rotor system. This could ultimately result in a condition where altitude cannot be maintained,
even at maximum power. An iced-up rotor system can also cause severe vibration. If any of
the signs for rotor icing is evident, carry out a precautionary landing.
3.18 Landing with a Deflated Tyre
Plan to land directly into the wind with minimum rate of descent at touch-down, if possible
on a grass runway. Maintain directional control with adequate pedal input. Consider the use
of some propeller thrust to increase rudder effectivity. Lower nose gently with the nose
wheel pointing straight.
Alternatively, if landing on asphalt is unavoidable, approach normally, with the intent of a
zero-speed touch-down directly into wind.
Only if impossible to recover the aircraft from the landing area should it be manoeuvred
under its own power, as this could further damage the tyre and wheel rim.
3.19 Failure of CSP/VPP Propeller (if installed)
Noticeable defect:
In case of a noticeable mechanical defect, indicated by sudden vibration or noise, perform a
precautionary landing.
Run-away:
Propeller pitch changes without command, usually resulting in unexpected or sudden
change in engine RPM and engine manifold pressure.
Run-away to FINE
: RPM will increase and propeller pitch will stop in full
FINE position. Reduce power if needed, to stay within RPM limits.
Run-away to COARSE
: RPM will decrease until propeller pitch stops in
full COARSE position. Reduce power if needed.
Continue according to emergency procedure ‘FREEZE’.
