Pilot Operating Handbook SECTION 3 H3 EasyFlyer Sport EMERGENCY SECTION 3 - EMERGENCY PROCEDURES This chapter contains all the checklists and procedures to be executed in emergency situations. Emergencies due to defects of the helicopter or its engine are extremely rare if the aircraft is checked thoroughly before each flight and continuously maintained.

Pilot Operating Handbook SECTION 3 H3 EasyFlyer Sport EMERGENCY FORCED DITCHING ➢ Autorotation procedure until contact with water. ➢ Lay the helicopter down on the left as soon as contact has been made with water in order to stop the rotation of the main rotor.
Pilot Operating Handbook SECTION 3 H3 EasyFlyer Sport EMERGENCY TAIL ROTOR OR TRANSMISSION FAILURE IN TRANSLATION ➢ Sudden yaw to the left cannot be controlled with the right pedal if the airspeed is below 100km/h. Above 100km/h, the vertical stabilisers remain efficient enough to maintain heading (with slight deviation however).
Pilot Operating Handbook SECTION 3 H3 EasyFlyer Sport EMERGENCY LOSS OF VISIBILITY In case of canopy misting, open air vents and lateral sliding vents to ensure proper ventilation. If the situation cannot be corrected or occurs suddenly, such as after a bird strike or canopy icing, maintain safe altitude by visual reference to the sides, using the open sliding window, if necessary.

Pilot Operating Handbook SECTION 3 H3 EasyFlyer Sport EMERGENCY ➢ Rotax 912ULS If GEN warning is alight, switch off all unnecessary electrical systems and land at the nearest place. The battery is expected, in good condition, to provide 15 minutes of reserve power to supply the aircraft instrumentation, avionics and fans, after which time electrical equipment may cease to function.

Pilot Operating Handbook SECTION 3 H3 EasyFlyer Sport EMERGENCY In any case, you should not follow your initially planned approach if you have a Low RPM warning. Fuel (Orange) This warning will light up when there are 15L of fuel remaining. The engine will run dry after about 45 minutes of operation at nominal power.

➢ Coolant liquid ➢ The quantity of unusable fuel The empty weight and the empty C.G. must be measured for each Dynali H3 EasyFlyer ‘Sport’ helicopter, once assembly is completed. The empty weight may not in any case (except for options) exceed the standard reference empty weight as indicated in this manual.
Before each flight you should : ➢ Check that the position of the C.G. of the Dynali H3 EasyFlyer ‘Sport’, as it will be on takeoff, is within the fore and aft balance limits.

The Dynali H3 EasyFlyer ‘Sport’ is equipped with dual controls. Apart from solo flights, for which the pilot must be in the left hand seat, the Dynali H3 ‘Sport’ may be flown from the left or the right hand seat. In order to guarantee the easy piloting of the aircraft, the left hand side must always be heavier than the right hand side.
SYSTEMS SECTION 7 - SYSTEMS The purpose of this chapter is to introduce the pilot who has not assembled his Dynali H3 EasyFlyer ‘Sport’ to the various systems forming part of this helicopter. Further information can be found in the assembly manual. We advise all pilots to read through this in order to better understand the design and mechanics of the Dynali H3 EasyFlyer ‘Sport’.
The stainless steel sleeves have a small slot in the middle. It enables the sleeves to open under shock, preventing the breaking of the aluminum legs. The tail boom of the Dynali H3 EasyFlyer ‘Sport’ is made of aluminum. It is supported by two carbon struts.
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS ➢ The Rotax 914UL 115HP with TURBO, which provides for the maintenance of the full power range at any altitude. Although there is some added weight resulting from the addition of a turbo and associated equipment, this version promises to be popular for heavy pilots in hot and high environments.
Page 54
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS Four V-belts transfer the movement to the receiving (driven) pulley which houses one freewheel. The freewheel is oil lubricated and can bear a torque of 660Nm. It drives the rotor while the engine is running and keeps it free of movement when the engine is stopped or idle (failure or landing).
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS MAIN TRANSMISSION GEARBOX (MTG) The main transmission gearbox transfers the rotating movement from the main transmission shaft to the main rotor mast. The MTG of the H3 is dimensioned to support 250 HP whereas in reality it only has to bear a maximum of 115 HP. The total weight of the assembled MTG is 15kg.
All controls operate through control rods with ball joint endings. The flight controls of the Dynali H3 EasyFlyer ‘Sport’ operate in the same manner as those of most other helicopters. The cyclic and the collective control the pitch of each blade via the swash plate.
Page 57
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS WARNING ! The controls are very sensitive, this being why we recommend frictions on the three controls. Fully unscrew and re-screw 6 threads the lateral frictions and 11 threads the pitch friction.
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS The friction of the collective lever is set by the degree of tightening of its attachment bolt. The rudder pedals act on the pitch variator lever of the rear rotor through two teleflex cables.
Pilot Operating Handbook SECTION 7 H3 EasyFlyer Sport SYSTEMS 7.10 FUEL CIRCUIT The engine is fed directly by 2 fuel taps, connected to the fuel tank. The two fuel taps each have a filter. The two fuel taps can be kept opened for checking state of the hoses.
We ask that each new owner/operator contacts us and remains in close contact with Dynali SPRL or his local authorised distributor in order to receive the latest service bulletins concerning the Dynali H3 EasyFlyer ‘Sport’.
7) Every 2400h. This operation must be performed in an authorised maintenance center by a qualified technician. Dynali SPRL recommends a full inspection of the machine every 12 months. This must be performed by an authorised maintenance center. Furthermore as from the 50 hour, the operation to be undertaken is, in fact, a series of operations.

Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS SECTION 9 - SAFETY TIPS General This section provides miscellaneous suggestions and guidance to help the pilot operate the helicopter more safely. It is essential to warn the owner/operator about several risks that are too often underestimated or neglected through force of habit and to provide with the experience acquired by the whole family of pilots of light helicopters.
Page 65
Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS Entering the vortex In the event of descending too fast or moving forward with a tail wind, there is a danger of entering your own vortex and catching up with your own turbulence. The rotor operates in turbulent air and loses a large part of its lift.
Page 66
Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS Lateral translation Excessive and longer lateral translation has to be avoided at all means. An engine failure during a lateral translation close to the ground may have fatal consequences. Flying low on fuel is dangerous Never intentionally allow the fuel level to become critically low.

Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS AND, ABOVE ALL, HE MUST NEVER ABRUPTLY PUSH THE CONTROL STICK FORWARD. Beware of demonstration or initial training flights A disproportionate number of fatal and non-fatal accidents occur during demonstration or Initial training flights.

Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS Parking Restrain/strap the rotor blades which flap in the wind. The shocks leave traces of impacts on the balls of the bearings. Transporting the helicopter on a trailer Without main rotor blades or support the rearward blade. Possibly, on a short trip, let the blades hang and prevent flapping by using straps left fairly loose.
Page 71
Pilot Operating Handbook SECTION 9 H3 EasyFlyer Sport SAFETY TIPS This sound always accompanies blade same position. The "roar" in the tail pipe comes from the pinions of the RTG. When the tail rotor turns slowly, rear blades, one after the other, falls in its roots, causing a “knock”.
Where this is not the case the general warranty of Dynali applies, this being of 24 months from the date of delivery ex-works Dynalii or 200 hours in operation, whichever of these events should occur first.

If a defect can not be remedied, or if the buyer can not reasonably accept the remedies proposed by Dynali, the buyer may demand a voiding of the contract of sale or re-negotiation of the sale price.
