4.4 Vibrations
Vibrations can occur due to flight in bad weather, incorrect flight regime, or due to the
technical failure on the airplane.
If unnatural vibrations occur, make sure you are not flying at a speed close to the stall speed.
The airplane vibrates while flying at the stall speed. In this case perform the change of flying
regime - fly at higher speed.
If you notice unusual vibrations during flight:
•
set RPM for the lowest vibrations
•
land at the nearest airfield or make precautionary landing
•
if the vibrations are getting worse make an emergency landing
4.5. Precautionary landing
If you for any reason, such as rough engine running, sickness or disorientation need to make
an off airport landing proceed as follows:
•
select a long enough and suitable landing site
•
make a pass at 100 km/h at the height of 50 m AGL to check for obstructions
and inspect the surface conditions
•
fly a traffic pattern
•
land in 1/3 of the landing area
•
before touch down turn magnetos and main switch OFF
4.6. Landing gear and tire failure
4.6.1 Main landing gear failure
Using the ailerons perform a one wheel landing and try to land on the functioning leg. Try to
keep the damaged leg up as long as possible.
4.6.2 Nose landing gear failure
In the case of nose landing gear failure, try to keep the nose up as long as possible. If
possible do not use brakes, because while applying brakes the inertia force actuating on the
center of gravity of the airplane is trying to bring the nose of the airplane down. Try to land in
an appropriate area and if possible against the wind, to slow down the landing speed against
the ground.
4.6.3 Tire failure
The landing procedure is the same as in the case of landing gear failure, depending on which
tire failed.
