FAA Approved
Procedures:
Engine Failure − Above 12 Feet and Below 500 Feet AGL
The Height − Velocity Diagram (Ref. Section V) depicts the combinations of air-
speeds vs. altitudes wherein a successful autorotation landing can be made in
the event of an engine failure. Flight within the cross−hatched regions repre-
sent airspeed/altitude combinations from which a successful autorotation land-
ing may be difficult to perform. Operation within the cross−hatched area
should be undertaken with caution.
In the event of a power failure during takeoff/low level flight, the collec-
tive pitch must be initially lowered to maintain rotor speed. The amount
and duration of collective reduction depends upon the airspeed and height
above the ground at which the power loss occurs.
As the ground is approached, flare as required to reduce forward speed
and rate of descent.
Touch down in a level attitude, increasing collective pitch to cushion land-
ing.
Avoid the use of aft cyclic or rapid lowering of the collective during initial
ground contact or during ground slide.
Procedures:
Engine Failure − Hovering Flight Below 12 Feet AGL
Do not reduce collective pitch.
Apply right pedal to prevent yawing.
Increase collective pitch as necessary to cushion landing.
PARTIAL POWER LOSS
Indications:
Under partial power conditions, the engine may operate smoothly with
reduced power or it may operate erratically with intermittent surges of
power.
Procedures:
Turning the start pump ON may smooth out an erratic operating engine
and/or restore power enabling the pilot to fly to a favorable landing area.
However, do NOT disregard the need to land.
If possible, fly at reduced power to the nearest safe landing area and land
as soon as possible. Be prepared for a complete power loss at any time.
