7.5.2 Precautionary landing A precautionary landing may be carried out due to low fuel and/or bad weather conditions. It is best to land at an airport whenever possible. But if an airport is not available, a landing may be made in a field or on a road.
7.5.3 Landing with a flat tire 1. Approach Normal 2. Touch down - good tire first, keep the damaged wheel above ground as long as possible using ailerons 3. Maintain the direction at landing run, applying braking control Date of Issue: 07/28/2010...
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 3. Note that if unbalanced wheel spins in flight, vibration may result.
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: 07/28/2010...

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 2500 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 (CCCCIGAAR – Lights, Camera, Action) 1. Controls - check of free movement 2. Canopy -closed and locked 3. Choke - off 4. Cowl flap -open 5. Instruments - set and in the green 6. Gas - fuel valve on left tank 7.
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.
8.2.4 Engine extraction and retraction 8.2.5 Best rate of climb For Rotax 912UL and VARIA 1.6 propeller the best rate-of-climb speed is 1000 feet/min. 1. Throttle - Max. continuous power (5 500 rpm) 2. Speed - 55 kts 3. Trim - adjust as needed to reduce stick pressure 4.
6. Master switch - off 7. Fuel valve - off 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!
Check before landing – GPS-FUSTALL 1. Gas - fuel on left tank 2. Pump -fuel pump on 3. Straps -tight 4. Flaps -0° or +10° 5. Undercarriage - down 6. Speed - 60kts 7. Trim - adjust as required 8. Airbrakes - unlocked and operational 9.
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.
Information on stalls, spins and any other useful pilot info Recovery from unintentional spin and stall 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.
Flight in rain When flying in the rain, no additional steps are required. Airplane qualities and performance are not substantially changed. Feathering of the propeller 1. Shut off engine with ignition key (off position) Engine restarting Follow same engine start procedures as in 8.2.1 Caution After extended soaring flight, the engine could be cooled down.

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 airplane is relatively low. Suitable surfaces to hold the airplane airframe are the rear part of the fuselage before the fin, wing roots, and cockpit forward frame.
Tie-down The airplane is usually tied-down after a flight day or when needed. This is necessary to protect the airplane 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.
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. It is neces- sary to dismantle airplane before loading to avoid damage to roadway signs.
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 gripping.
Page 74
• Wing Installation: Set the left wing on the pins and check automatic connection of control rods. Connect the fuel lines and fuel sensor. Then secure the rear auxiliary pin. Follow with the right wing, insert the wing in automatic connection device and secure the rear auxiliary pin.
Page 75
Insert the main eccentric pin, turn it 180 ° to tighten both halves of the wing together. Then secure the main pin with a bolt through the handle and at the rear with a safety pin. Check control system and fuel gauge function. Use an adhesive tape to cover the gap between the center section and the wing root.
Airplane Disassembly Follow the Assembly steps in reverse order. Date of Issue: 07/28/2010...

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. Boating supply companies such as West Marine carry a large supply of cleaners and wax cleaners such as Maguiers which are designed for use on gel coat surfaces.
