Power failures

General

Engine failure can be detected by :
•
Yaw acceleration, nose to the right,
•
Engine noise level decreases,
•
Tachometer needles desynchronization on the EPM (engine
decreases)
•
OIL P warning on the EPM and OIL P red light coming ON.
•
Plasma beeper,
•
Rotor speed decreasing and "low NR" horn.
Caution : A slow decay in engine power, caused by carburetor icing
Primary transmission failure can be detected by :
•
High yaw rate, nose to the right,
•
Engine noise level increases,
•
Tachometer needles desynchronization on the EPM (engine
increases). Eventual engine overspeed only if the governor is OFF
•
Rotor speed decreasing and "low NR" horn.
In case of a primary transmission failure, apply following power failure
actions. Roll off the twist grip as soon as possible.
Safe landing may not be possible if the power failure occurs within
the "unsafe" zone of the H/V diagram (refer to section 5).
3-2
or air filter clogging, is compensated by the governor and can
be overlooked by the pilot.
The MLI indication will not change while in PWR mode, but
will rapidly shift to FLO mode, then increase to 100%.
Operation inside this zone should be avoided.
