Tail Rotor Failure - Eurocopter AS 350 83 Flight Manual

FLIGHT MANUAL
5 SMOKE IN THE CABIN .
5.1 If Source of Smoke is identified
-Shut off the corresponding system.
-If necessary, use the fire extinguisher *
-Air the cabin by opening:
.The front ventilator
.The ventilation ports
.The bad weather windows.
5.2 If source of Smoke is not identified
-Shut off the heating * demisting system.
If the smoke does not clear:
. .Switch off the electrical master switch ("ALL OFF").
.When the smell of smoke has cleared, set all switches to "OFF",
including the generator and alternator (if installed), close the
-cabin ventilators.
.Reset the "ALL OFF" electrical master switch to normal position.
.Switch on the generator, check voltage and current.
.If everything is normal, switch on the circuits one by one until the
malfunction is identified.
NOTE: If the electrical power supply system is faulty, carry out the
-appropriate procedure, as detailed in SEmON 3.3.
6 TAIL ROTOR FAILURE
6.1 Tail Rotor Drive Failure
Loss of the tail rotor in power-on flight results in a yaw movement to
the left; the extent of such rotation will depend on the power and
speed configuration at the time the failure occurs.
6.1.1 Failure of the Tail Rotor in Hover or at Low Speed
-I.G.E. : set the twist grip to the idling detent and cushion touch-
down by pulling the collective pitch lever.
-O.G.E. : reduce collective pitch moderately, to reduce yaw torque,
.
and simultaneously start to pick up speed.
6.1.2 Failure in Forward Flight
-In forward flight reduce the power as much as possible and maintain
forward speed (weathercock effect), select a suitable landing area
for a steep approach at a power enabling a reasonably coordinated
flight.
-On final approach, shut down the engine and make an autorotative
landing at the lowest possible speed.
