Section 7 provides checklist and amplified procedures for coping with emergencies that may occur. Emergencies caused by airplane or engine malfunctions are ex- tremely rare if proper pre-flight inspections and maintenance are practised. However, should an emergency arise, the basic guidelines de- scribed in this section should be considered and applied as necessary to correct the problem.
9. Master key - switch off position before landing 10. Land Note Skip 6-10 if necessary. 7.1.3 Engine failure in flight (Forced landing) 1. Speed - keep gliding speed at 55 kts - sink rate 180 feet/min 2. Altitude - below 100 feet: land in take-off direction - over 150 feet: choose landing area 3.
In-Flight start 1. Speed - keep speed a bit higher at 65 kts 2. Altitude - check 3. Landing area - choose according to altitude (safest area) 4. Master switch - on 5. Fuel valve - open 6. Choke - closed initially, then as needed 7.
7.3.2 Fire during take-off 1. Fuel valve - off 2. Throttle - full 3. Speed - 55 kts 4. Master switch - off 5. Ignition - off 6. Land and brake 7. Abandon the airplane 8. Extinguish fire if possible or call fire department. Date of Issue: 24/07/2010...
7.3.3 Fire in flight 1. Fuel valve - off 2. Throttle - full 3. Master switch - off 4. Ignition - off after using up fuel in carburettors then engine stops 5. Choose of area - heading to the nearest airport or choose emergency landing area 6.
Landing emergencies 7.5.1 Emergency landing 1. An emergency landing may be carried out due to engine fail- ure and when the engine cannot be restarted. 2. Speed - 55 kts 3. Trim - trim the airplane 4. Safety harness - tighten 5.
7.5.2 Precautionary landing A precautionary landing may be carried out due to low fuel and/or bad weather conditions. 1. Choose landing area, determine wind direction 2. If a COMM is installed - report your plan to land and land area location to nearest ATC 3.
7.5.4 Landing with a defective landing gear 1. If the main landing gear is damaged, perform touch-down at the Lowest speed possible and maintain direction during land- ing run, if possible 2. If the tail wheel is damaged perform touch-down at the lowest possible speed and maintain direction during landing run, if possible.
Recovery from unintentional spin Warning Intentional spins are prohibited! There is no tendency of spontaneous uncontrollable spin entry if normal pilot techniques are used. Should an inadvertent spin occur, the following recovery procedure should be used: 1. Throttle retard to idle 2.
Other emergencies 7.7.1 Vibration If vibrations appear: 1. Set engine speed to power setting where the vibrations are the lowest. 2. Land at the nearest airfield or perform a precautionary landing according to 3.6.2 7.7.2 Carburetor icing Carburetor icing mostly occurs when getting into an area of humid- ity formation.
Pre-flight check The pre-flight inspection is very important because an incomplete or careless inspection could allow airplane failure. The following pre-flight inspection procedure is recommended by the airplane Manufacturer: Date of Issue: 24/07/2010 8-12...

Before engine starting and Engine starting 1. Fuel valve - on 2. Ignition key - off 3. Circuit breakers - in 4. Throttle - set for idling 5. Choke - according to engine temperature 6. Control stick - fully pulled 7.
Caution The starter should be activated for max.10 sec., then 2 min. pause for engine cooling. After engine starting adjust the throttle for smooth running at 1500 rpm. Check oil pressure which should increase within 10 sec. Increase engine speed after oil pressure reaches2 bars and is steady.
8.2.2 Taxiing The maximum recommended taxiing speed is 8 kts. The direction of taxiing can be controlled by the steerable rear wheel – rudder. Use the lever on the control stick to operate the brakes intermittently. Do not ride the brakes which can cause overheating of the brake pads and possible locking of the brakes.
8.2.3 Normal takeoff Before take-off (CCCIGAAR – Lights, Camera, Action) 1. Controls - check of free movement 2. Canopy -closed and locked 3. Choke - off 4. Instruments - set and in the green 5. Gas - fuel valve on left tank 6.
Take-off Gradually increase the throttle (max. power) to set the airplane into motion. The direction of take-off run can be controlled by steerable tail wheel and rudder. Place the stick 2 inches forward of the rear stop. The airplane takes-off at a speed above 38 kts, then slightly push forward the stick to reach climb speed of 55 kts.
8.2.5 Best rate of climb For Jabiru 2200 and Sensenich propeller is the best rate-of-climb 1000 feet/min. 1. Throttle - Max. 2. Speed - 70 kts 3. Trim - adjust as needed to reduce stick pressure 4. Instruments - CHT, Oil temp. and pressure within limits. Caution If cylinder head or oil temperature exceed limits, reduce the angle of climb to increase airspeed and allow better cooling.
Cruise The airplane flight characteristics are very forgiving within permit- ted limits of airspeeds, configurations and C/G range. The airplane can be controlled very easily. Refer to the Section 5 par. 5.3.1 . Warning Never remove your feet from rudder pedals during flight! Your feet are making tension in rudder control line! Approach Descent...
Check before landing – GPS-USTALL 1. Gas - fuel on left tank 2. Pump -fuel pump on 3. Straps -tight 4. Undercarriage - down 5. Speed - 55kts 6. Trim - adjust as required 7. Airbrakes - unlocked and operational 8.
Normal landing Landing The airspeed during final is slowly reduced, so that the touchdown speed is about 38 kts. Gradually pull the stick after touchdown. The landing run can be shortened by braking. Caution If the airplane rebounds 2 or 3 feet hold the control stick fully pulled.
After landing 1. Engine speed - set as necessary for taxiing 2. Fuel pump - off Engine shutdown 1. Instruments - engine instruments within limits 2. COMM + intercom - off 3. Ignition key - off 4. Circuit breakers - off 5.
Should an inadvertent spin occur, the following recovery procedure should be used: 1. Throttle retard to idle 2. Control stick hold ailerons neutralized 3. Rudder pedals apply full opposite rudder 4. Control stick forward elevator control as required to break the spin 5.
Engine restarting Follow same engine start procedures as in 8.2.1 Caution After extended soaring flight, the engine could be cooled down. Use the choke if engine fails to start initially. Date of Issue: 24/07/2010 8-29...
Servicing fuel, oil, coolant Fuel check 2 x wing fuel tanks (50 l each, 100 l total) are an integral part of the wings, and fuel quantity sensors are located inside the wings. In addition, a coarse filter, fuel valve, and fine filter are parts of the fuel system. For draining use the drain valve located on the bottom of the wing.

Towing and tie-down instructions Towing It is easy to tow the airplane a short distance by holding the blade root because the empty weight of this aeroplane is relatively low. Suitable surfaces to hold the airplane airframe are the rear part of the fuselage before the fin and wing roots..
Page 70
Tie-down The airplane is usually tied-down after a flight day or when needed. This is necessary to protect the aeroplane against possible dam age caused by wind gusts. The airplane is equipped with tie-down bolts on the wing tips. Procedure: Check: Fuel valve off, Circuit breakers and Master switch off, Ignition key off.
To lift the wings, push on the wings lower surface at the main spar. Do not lift by the wing tips. Levelling Refer to the Operating, Maintenance and Repair Manual for U-15 Phoenix for more details about levelling. Road transport The airplane may be transported in a suitable trailer.
Airplane Assembly Note No special qualification needed for assembling/disassembling. Degrease and clean all connecting parts and grease again using suitable lubricants. • Horizontal Tail Unit (HTU) Installation: Set the HTU on the two main pins and at the same time insert the elevator control bell into automatic grip- ping.
• Wing Installation: Set the left half of the wing on the pins and check automatic con- nection of control rods. Then secure the rear auxiliary pin. Follow with the right half of the wing, insert the wing in automatic connection device and secure the rear auxiliary pin.
Page 74
Cleaning and care Use cleaning detergents to clean airplane surface. Oil spots on air- plane surface (except the canopy!) may be cleaned with appropriate de- greasers. The canopy should be cleaned only by washing it with lukewarm water and mild detergents, using clean, soft cloth sponge or deerskin. Then use suitable polishers to clean the canopy.
