  • Page 75: Section 9 - Safety Tips

    Pilot Operating Handbook SECTION 9 H3 Sport 135 HP 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 76 Pilot Operating Handbook SECTION 9 H3 Sport 135 HP SAFETY TIPS Never push the control stick forward to descend or to terminate a pull-up (as you would in an airplane). This may produce a low-G (near weightless) condition which may result in a mast bumping occurrence, causing fatal damage to the rotor mast.
  • Page 77 Pilot Operating Handbook SECTION 9 H3 Sport 135 HP SAFETY TIPS Do not push the envelope and remain easy on the controls Avoid abrupt control inputs or accelerated manoeuvres, particularly at high speed. These produce high fatigue loads in the dynamic components and could cause a premature and catastrophic failure of a critical component.
  • Page 78 Pilot Operating Handbook SECTION 9 H3 Sport 135 HP SAFETY TIPS Loss of visibility can be fatal Flying a helicopter in obscured visibility due to fog, snow, low ceiling, or even a dark night can be fatal. Helicopters have less inherent stability and much faster roll and pitch rates than airplanes.
  • Page 79 Pilot Operating Handbook SECTION 9 H3 Sport 135 HP SAFETY TIPS realize their loss of depth perception when flying over water. Flying over calm glassy water is particularly dangerous, but even choppy water, with its constantly varying surface, interferes with normal depth perception and may cause a pilot to misjudge his height above the water.
  • Page 80 Pilot Operating Handbook SECTION 9 H3 Sport 135 HP SAFETY TIPS Beware of demonstration or initial training flights A disproportionate number of fatal and non-fatal accidents occur during demonstration or Initial training flights. The accidents occur because individuals other than the pilot are allowed to manipulate the controls without being properly prepared or indoctrinated.
  • Page 81 Pilot Operating Handbook SECTION 9 H3 Sport 135 HP SAFETY TIPS Hovering above high-level grass Do not take off in high level grass. There is a danger of fire. Do not perform hover flight above high level grass. The ground effect may be lost.
  • Page 82 Pilot Operating Handbook SECTION 9 H3 Sport 135 HP SAFETY TIPS After a hard landing The chassis cannot be repaired if damaged. It must be replaced. The angle between main transmission shaft, main rotor mast and tail boom must be checked.

  • Page 83: Section 10 - Warranty Conditions

    WARRANTY SECTION 10 - WARRANTY CONDITIONS The Dynali warranty covers the design of its helicopters as a whole as well as all parts designed by Dynali and manufactured by Dynali or sub-contracted by Dynali. Warranty conditions applying to the equipment, instruments and battery are those of the suppliers concerned. 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.
  • Page 84 If a defect cannot be remedied, or if the buyer cannot 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.
