3.8 Other emergencies
3.8.1 Control failures
Aileron control fault - the aeroplane is possible to control laterally by
the secondary effect of the rudder. Start and
termination of the yawing up to bank angle 15°
is possible using the rudder only.
Rudder control fault - the yawing and the termination is conducted
with help of the lateral control of the ailerons.
.
3.8.2 Vibrations
The power plant can be the source of the vibrations.
1. Reduce engine speed to minimize the vibrations.
2. Proceed to the nearest airport for landing or select a suitable precautionary landing
field in accordance with item 3.6.2.
3.8.3 Rescue system
For operation and handling with rescue system to see Operation manual delivered by
producer of eqipment.
3.8.4 Unsecured cockpit canopy
If the „Before Take-off“ Checklist is performed insufficiently (cockpit canopy -
latched), there is possibility of partial cockpit canopy latching. The canopy is equipped
with a lock on the upper rear section of the frame and it is secured by the lock lever
shot backwards. The lock pin is projected as latch with compression spring. The gap
cca. 8-12 mm will be rise between fuselage and cockpit canopy, which is constant
during straight line flight without
side-slipping due to the air flow and the function of the gas struts. Partial cockpit
canopy latching will stack up by the noise increase due to the agitated air through the
gap between fuselage and cockpit canopy. Partial cockpit canopy latching is possible
to close safely during straight line flight without side-slipping by the following way
according to appropriate stage of flight:
3.8.4.1 During take-off roll
1. Abort the take-off, if the cockpit canopy unlatching is detected during take-off roll.
2. Close and latch the cockpit canopy by normal procedure ( the cockpit canopy
handle pull down and check the cockpit canopy latching by position of the red ring on
lockpin ) after stopping.
