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. If there
should occur a case of emergency, the guidelines of this chapter should be followed in
order to manage the emergency. However, evaluation of the situation and remedial
actions to deal with it remain the responsibility of the pilot.
Strict compliance with the engine manufacturer’s maintenance schedules, operational
procedures is essential. The helicopter must always be flown with the risk of engine
failure in mind, and must not be flown over any large bodies of water where a forced
landing cannot be safely executed.
