PRE-FLIGHT CHECK 1 2 3 4 5 18 6 7 16 17 8 15 9 10 11 13 14 12 Remove upper engine cover, any canopy cover, pitot-static tube cover. Important places on the aircraft are shown in the above diagram (with numbers). Some checks will require the removal of covers. KAPITOLA 4: Standard procedures The aircraft should be check as follows: a) Canopy - Master ON, check sufficient volume of fuel - Master, Magnetos and other switches OFF! - Fuel OFF - Visual check of the interior, remove all free-moving objects - Check for the free-movement of controls b) Engine (2. 3. 4.) - remove upper cowling, visual check of engine and accessories - check the status and fixation of units, tightening and locking of screws, condition of tubes (look for cracks), condition and fixation of electric-installation. - check the volume of oil and cooling liquid - check propeller blades, fixation of propellers cone - Replace the cowling and lock it c) Front Landing gear (2. 4.) - check the tire pressure, and condition of each gear d) Wings (5.18) - visual check of leading and trailing edge - visual check of fuel tanks, check the volume of fuel - check the Pitot tube (status, fixation, direction) e) Ailerons (6. 17.) - visual check of condition - check easy and free movement - check the hinge-line of the ailerons f) Flaps (7.16.) - visual check of condition - check free movement, locking of each flaps position - check hinge-line of flaps g) Main landing gear (8. 15.) - check pressure of tires - check fixation h) Fuselage ( 9.14. ) - visual check for any damage - check antenna (condition, fixation) i i) Horizontal Tailplane ( 11. 12. ) - visual check of condition - check the connection to vertical tail surfaces - check hinge of elevator and trim surfaces - check free movement, easy to control k) Vertical Tailplane (10. 13. ) - visual check of condition - check the rudder hinges - check condition of control cables (strain, secure, free-movement) 23 PROCEDURES AFTER ENTERING THE AIRCRAFT STARTING THE ENGINE 1. check the locking of the ballistic rescue system (if there is one) 2. set your position of seats 3. canopy – closed and locked 4. safety belts –lock and tight 5. controls – free movement 6. flaps – check function 7. brakes – check function 8. Master ON 9. instruments – check the values, settings 10. trim – check the function, start position neutral 11. fuel valve – open (left or right) 1. fuel levels – check the volume of fuel in tanks 2. radio Off 3. fuel valve open to the tank with the larger volume of fuel 4. throttle (idle position for cold engine with choke combination, 1 turn for warm engine) 5. choke depends on the temperature of the engine (full for cold, not needed if the engine is warm) 6. set minimal pitch to propeller blades for start (if adjustable propeller) 7. check the space around propeller to be sure that it is clear 8. Magnetos ON – both circuits 9. electric pump - On 10. starter 11. rpm after start 2500 rpm 12. check oil and fuel pressure 13. switches ON (radio, strobe, …) Warning: - Before starting you will have carefully read the Manual for the Rotax Engine! - Before warm up or testing the engine the airplane has to be: - in position against the wind - wheel chocks in place - assistant with a fire extinguisher nearby - The engine must not be started without pilot in the aircraft! - Getting In or Out with the engine running is strictly prohibited! Warnings: Maximum time for trying to start up the engine is 10s. Another start can be repeated after cooling down of the starter, about 2 minutes. Oil pressure must rise in 10 seconds after start. After reaching stable values of oil pressure (above 2 bar) rpm can be increased. Aircraft is using integral fuel tanks in wings. It is controlled by three-way valve (opening left or right side and off position). Lateral balance can be maintained by using fuel from the left and right tanks to keep fuel levels in both tanks equal. WARMING UP AND PRE-FLIGHT CHECK OF THE ENGINE PROCEDURES BEFORE TAXING PROCEDURES BEFORE TAKE-OFF 1. brake the aircraft by chocks 2. all controls in neutral position 3. minimum pitch on propeller 4. set rpm as 2000 rpm and let it run for 2 min, then continue warming with 3000 rpm until oil temperature reaches 50°C 5. slowly increase rpm to maximum ( or at least to 4000 rpm), for 5s, slow to the idle, and repeat 2 or 3 times 6. Set to 3850 rpm, check magnetos by turning them off separately. The rpm should NOT decrease by more than 300 rpm. The difference in rpm drop should be not more then 115 rpm.

It is better to set the neutral position to easy fit in. Horizontal tail surfaces Procedure: − remove covers − disconnect the wires to trim and to strobe light in front socket. In rear one disconnect the rod for controlling elevator − remove 4 screw of attachment to vertical tail surfaces − put it on soft clean surface Putting on: − opposite procedure Note: Assemble on place with possibility to fly! During carrying part of aircraft hold it close to the rivets lines (ribs). Replace old self-blocking nuts with new ones. Do not loose some parts! Procedure − remove covers of controls and floor − disconnect aileron push rods to the wing − disconnect fuel tubes from the wing − disconnect pitot-static tubes – left wing − disconnect wires to the wings − remove the main spar bolts (3+3 pcs) and remove the rear spar bolt, leave one main spar bolt up and one main spar bolt down − hold the end of the wing and carefully remove last two bolts − pull out the wing carefully – hold the flaps (it will automatically disconnected when the wing is pulled out) − put the wing on soft clean surface − same procedure for second wing PART 7: Disassembling 31 Manufacturer: DOVA AIRCRAFT, s.r.o.
