- if you have any doubts the landing gear is properly open and
locked, check visually yellow-black flag-arrow via check windows
- this visual check is superior to electronic information
- in case of one leg stays locked, safe procedure is to retract other
legs as well, and perform belly landing. When landing on grass,
close flaps, stop engine with 2 blades proppeler in horizontal
position to reduce demage to minimum
CAUTION:
When landing gear emergency release is used, landing gear stays
open without possibility to retract it without re-assembling by authorised
technician!
3.10. VIBRATIONS FROM ENGINE OR OTHER ENGINE
PROBLEM
Vibrations:
- use engine power with minimal vibrations
- in case the airplane has in flight adjustable propeller try to find in
manual control regime angle with minimal vibrations
- land as soon as possible, consider off-airfield landing if vibrations
increase
Oil pressure drop - probability of engine failure. In this case reduce
engine power and land as soon as possible (before the failure occurs),
consider off-airfield landing.
3.11. INADVERTENT ICING ENCOUNTER
- throttle increase above normal cruise settings
- course reverse or alter as required to avoid icing
- altitude climb (if possible)
3.12. EXTREME TURBULENCE ENCOUNTER
- airspeed recommend 200 km/h (V
RA
=249 km/h)
- safety belts tighten
- loose objects fixed
